Indoor grow cab (converted Home depot wardrobe)
4 pots, two left over KC-36 and two Dutch Passion Oasis
Makeshift growlight - featuring a 125 watt CFL (rated 5000k) with an aluminum turkey pan reflector
one bottom fan (and digital thermometer) blowing cool bottom air at the pots
One top fan 'sucking' the warm air up
average cab temperature 27 Celsius
After 3 days of sprouting only one seedling (one of the KC 36's) popped out of the soil (I did presoak the seeds for 12 hours) on Aug 5th
Still no action with the other seedlings, so I'm soaking 3 more Oasis seeds. This time I'll monitor every 12 hours and only plant them once the seeds have split open.
I'll add a 45 watt soft white CFL to the current one when flowering for extra red spectrum.


Here's what it looks like so far:

I like the light setup haha pretty ghetto :D
good luck to you mate! keep us updated!

u get much bud with that amount of CFL light?

Good luck man! I sprouted under a 12" fluorescent above my sink when i was just messing around, can't wait to see how it goes!

Yeah what kind of yield was your last grow?!?! Don't let them give you shit about it either keep trucking rubber ducky!

CONVOY!

err...... sorry flashbacks of old movies.

"featuring a 125 watt CFL (rated 5000k) with an aluminum turkey pan reflector"

I love this m8.
This one I'm gonna follow. I love when people just look on ther situation and see what they can do and jump right into it.
I am sure you will get bud, hang in there and don't expect loads of it. Do keep us posted though man there are far to few grows like this here even though I am sure they represent a very large portion of the growrooms around the world.

Best of luck.

Yield...I really have nothing to compare it to, I guess it's passable for a small grow of a few plants at a time? I've been changing things at every grow too, keeping what works and improving on what needs to be improved.

The big 125 watt CFL and the Home Depot wardrobe I got last year. I've been adding various CFL's and light fixtures over the past two years. Heck my first Mango grow was in a much smaller cabinet, using a pair of 45 watt soft white CFL's.

As long as the cabinet temps stay within a safe range I could use the 125 watter with both 45 watters for a good light spectrum with enough reds...that would give me 215 watts for a surface a bit smaller that 2 feet square.

The current setup is discreet enough not to raise attention and the wardrobe doubles as an actual storage compartment when I ain't growin'! ;)

Based on Roughrider's info:


2000 lumens sq. ft./21500 lumens sq. m. = Absolute minimum for growth. You won't get much from this, especially after the plant has grown a bit. Not really enough to flower well.

3000 lumens sq. ft./32250 lumens sq. m. = Pretty Good growth. Enough light for the entire light cycle, although your yields may be lower.
4000 lumens sq. ft./43000 lumens sq. m. = Very good growth. Once you pass around 3500, growth rate and ability goes up fast.

Over 5000 lumens sq. ft./53750 lumens sq. m. = Optimal growth. Dense growth in all stages.

I measured my wardrobe's floor and it's well under 2 square feet. The 125 watt CFL generates approximately 13895 lumens, which would fall into the "pretty good growth but limited yield" area.

I went through my CFL box and came across a 45 watt rated at 3000 lumens, 4100K. So I figured that by supplementing the 125 watter with the 45 watter I'll be in the very good to Optimal growth area...

The three Oasis seeds I was soaking have begun to sprout, so I planted them. Here's the setup as of this morning. It was a bit of a challenge to get everythig to fit, but I've come up with a good compromise I think...the 45 watter is focused on the KC Brains that already sprouted out, and the three Oasis are crammed under the 125 watter...current cabinet temerature with both lights on: 29.3 Celsius, within safe parameters...keeping my fingers crossed! :D

That's one powerful CFL. I noticed most 125 watt's are rated for between 12,000 - 12,800 Lumens after googling it. But still that's alot.

I just might have to go get myself one.

I just might have to go get myself one.

It was an approximation based on a chart I found (should have saved it) stating that a CFL with a 5000K temperature can generate 111 pupil lumens per watt, so I multiplied it by 125 which gave 13875 lumens (someone 'splain to me the difference between lumens & pupil lumens?).

I calculated that for optimal growth my cab requires 15500 lumens. As you state, 12000 sounds more like it, so if I add up both CFL's, 12000 + 3000 I get 15000, so I'm still pretty close to optimal, if it's more like 12,800 then I'm actually exceeding optimal!

Temps settling near 31 Celsius...still acceptable but I'll really have to keep an eye on it an make sure it doesn't exceed 35C...

Pedro de Pacas
08-13-2008, 05:01 AM
Found the link! There's a chart towards the end of the document. While not fool proof it can serve as a guideline to determine lumens/pupil lumens per watt when it's not specified by the manufacturer!

Wasn't busting on you at all by the way. And thanks for the chart!

I was actually just curious because I've found contradicting things on my cfl's. So i figured it was the same for you.

I don't go by the book anyways. :D

It's all good :thumbsup: your input is actually quite helpful in fact! Having a more conservative figure allowed me to recalculate my lumens requirement and figure out that my setup is still within optimal or close to optimal conditions!

Okay! One of the Dutch Passion Oasis seeds is showing sign of life...but I'm a bit concerned: what I'm seeing is a very pale split pod and hints of root with shades of green.

I'm concerned it might burn under the CFL, so I added a very thin layer of moist potting soil to protect the root (about 1 mm thick, I don't want to impair growth either).

So...I'm keeping my fingers crossed, hopefully by the end of the day I have 3 healthy babies to grow along with the KC-36 that sprouted last week! Wish me luck! :)

Hopefully my zoom will show that two of the Oasis seeds are sprouting out! One's still camera shy...the last one is the KC-36 which is now a week and a few days old!

Pedro,

Looks like you have got your math down and figured out the lumens needed (good and helpful research for us all )

There is one thing I noticed in the pics that you have not done and will help get more lumens to the plants:)

In your grow box it looks like the walls are still bare wood. Wood is a poor reflector of light and is absorbing precious lumens that would be more beneficial to the plants than the walls. I suggest going to Home Depot and buy some Ultra Pure White Flat Wall Paint. This works as an excellent reflector of light and will make a lot more lumens available to the plants by not being absorbed by the walls.

In CFL grows this is very important because you are already down in intensity compared to HID lighting. So any light available needs to be absorbed by the plants and not the walls, You may want to go as far as painting the inside of your reflector, Aluminum is a very poor reflector of light in fact it is close to gray in the reflectivity scale

The best reflectors of light are Mylar, and Flat White Paint, both are in the 90% range, Aluminum and Gray are around 50%, and Flat Black is close to 0%

Best of Luck with your grow JG

It just seems growing at home ought to be cheap! If you have a brain and no money, Or, if you have the money and are too attached to it: you have shown us what you can do. This can be an expensive hobby for medicine. Nice to see you do it on the cheaper side. In no way will the electricity be cheap.

Tons of info, straight up. Nice start for your log!!! pr

Thx! The wood surface has a bit of a sheen to it, agreed not the best reflection capacity but it's not bare wood either, it's veneered pressboard and the venner has some sort of lacker to protect it.

08-16-2008, 03:48 PM
Awrite! 4 for 4 in the sprouts, however...given the spot where the seed's sprouted from, I think it's one of the seeds I believed dead that decided to come up...I might have 2 sprouts in one pot! Things are becoming verry interresting!

Here's a little reflective "fence" I've come up with those reflective windshield reflectors, all held together with paper clips for easy access (watering purposes and raising the lights & stuff). I just hope it doesn't effect the cab temperatures...

also enclosed is a few pics of the new babies! :cool:

Pedro de Pacas
08-19-2008, 03:15 PM
Removed the reflective fence...it just trapped too much heat, I'll have to figure out something else for extra reflection...I need more potting soil, two of the babies are too leggy for my own taste!

Puffzter
08-19-2008, 05:02 PM
That fencing looks pretty cool otherwise man.
Cant u lift it a bit over the floor so cool air can be sucked in under it?
That would certainly lower the temperature in the "bowl" it creates.

Would you be able to staple the windshield sunshade up against the wood veneer? I agree with Puffz that lifting it would allow a wind tunnel effect, thereby serving to reduce the heat. I really like your setup though - it's something I could do; and, I am trying to come up with some cheap, effective, and easy ideas for an indoor grow to begin later this year.

I can't wait for your lil' ladies to get bigger. I need to do some research on these strains, as I don't know a thing about them, but they sound good. Keep up the good work - I'm already looking forward to an update.

Be good out there!

Pedro de Pacas
08-20-2008, 02:53 AM
Bought some organic potting soil, used it to add support to the two leggy babies and prepared the bigger pots once they're ready to repot (all I'll say is that they're square, 8" X8" X7" and that you guys'll get a good laugh when you see them... ah those Dollar store prizes! :D ).

I didn't follow a set mix, I'd guess-timate it at 3 parts organic potting soil, 1 part vermiculite and 1 part perlite. :wtf4:

I reinstalled the reflective fence to create that wind tunnel effect...I'll gauge the success of it when I monitor the temps tomoprrow morning! Again I used 'dollar store prizes': glue-on coat hooks and paper clips to hook the 'fence' up.

I'm still seriously considering the 150 watt HPS kit I found on Ebay (very reasonably priced too) for flowering this grow...matbe suppement my big CFL with a red PAR LED bulb or two to keep the temps down?

Pedro de Pacas
08-20-2008, 05:34 PM
Okay, raising the reflector fence seems to have brought the cabinet temperatures down to a safer level. I took the babies out for a watering and took a group picture:

Random thoughts about this grow:


While the current light array is far from perfect it's serving the purpose: the KC36 is growing short and bushy. If it's any indication of what the Oasis plants will look like (it is 9 days older than the Oasis plants) I'm laughing!
The LED grow discussion has gotten my attention. Less power consumption, energy savings, less of a chance of the Landlord becoming suspicious, cooler cabinet temperatures, savings on AC, etc. The Cree Xlamp kit has my attention, it (or perhaps two of them) might be the perfect solution for my 'stealth cabinet grow' setup...I'm waiting for them to reply to my shipping quote request.


CFL's have served me well so far (okay, well enough ;) ), but the heat buildup from the multiple ballasts can't be good for the plants, and quite frankly the heat buildup makes me nervous...I might be a bit paranoid but I don't want to start a fire!

Pedro de Pacas
08-26-2008, 03:56 PM
Okay, I did a lot of number crunching and at this stage, getting a 150 Watt HPS kit would be cheaper than the suitable LED alternatives. I'd still prefer an LED grow light, but..


I'm currently using a total of 170 watts in CFL's for vegging (that's the actual wattage, the incandescent equivalent would be about 600 watts)
150 watts of HPS would use 20 watts less of energy while providing better light penetration (according to what I've read so far)
Ok, so I did get a Chinese-made LED panel...as long as it works I'll use it for supplemental light, I didn't pay much for it and extra red spectrum won't hurt.


So this is turning into a true 'mixed light' grow: CFL for vegging and HPS/LED for flowering...
:hippy:

Pedro de Pacas
08-27-2008, 02:59 PM
Okay, changes! The reflector fence was too bulky and in the way, so I lined the wardrobe walls wil aluminium foil (yea, I know, mylar's better but foil's cheaper and easier to find! ;) ).

I figured that more space would improve air circulation too. Next, I replaced the aluminium turkey pan reflector - it trapped too much heat underneath. Which brings me to the next point: wood for a light fixture, poor choice, wood warps!

The new reflector is a "cookie sheet" (also aluminium) which should trap less heat. Also, I made sure the ballast wasn't covered to make sure its heat rises to the top of the wardrobe.

I'll try to take tempreature samples to see how well this works out, the temps were up to 35,9 Celsius when I decided to make the change. Photos...KC's still bigger than the rest (since it's 9 days older); leggy 1 & 2 seem to be catching up, stubby is showing some developement...and looky here: one of the seeds I thought was dead has decided to pop out...I got 5 plants out of the bunch! Only 3 non-viable/dead seeds...to be expected I guess!

This is turning into one long, slow vegging period, but flowering will happen under 150 watts of HPS, I can't wait to compare the results to my prior all CFL grows!

:hippy:

Foil is junk, flat white paint, you can do the whole cab for under $10. You need to exhaust that heat out of the cabinet, blowing it to the top won't cut it, get exhaust and passive intake, or leave the door open a little at least. You will need to change that when you go to flower though.

I might have found another alternative. Working on the temps too, this is a good starting point:

Its easy to think foil is a good thing but it eats light to a degree that even your unpainted wall will probably be as good if it is not dark.

Love to read about your op m8. A work in constant progress. :)

Pedro's back folks! Wanting the grow wardrobe to pass off as a regular storage space when I'm not growing presents a few challenges...but I think I found the appropriate solutions.

Frirst, the reflective surfaces: I did a bit more digging, and came across the "Ask Ed" column in the Cannabis Culture site. Turns out some Hydroponics farms use flat white cardboard for reflectors, which has the drawback of getting dirty quickly and needing frequent replacements due to moisture damage.

I don't use sprinklers and I grow from potting soil, and I found flat white cardboard at the nearest discount store. VoilÃ*: removable reflectors.

Second, the heat and air circulation or lack thereof: I drilled a hole at the bottom to let the power cord out (rather than through an un-nailed flap of the rear veneer panel), a second hole (3" in diameter) as a passive air intake and another 3" hole in the top, dead center to allow exhaust.

Using a bathroom fan (a simple 50 CFM) and a 5' long 3" diameter flexible exhaust hose the air is sucked out of the wardrobe through the top hole. When not growing, the bottom holes will be covered with boxes and the top hole with one of those push on/off cabinet lights.

Major improvement with the cabinet temps! :thumbsup:

Pedro de Pacas
08-30-2008, 06:35 AM
Ugh...my DIY fixture fell apart, so I had to do some quick thinking...not the best solution but here goes:

-I've reworked the 125 watter in its old cone (Ikea) reflector, it's my main "central" fixture.

-for when the babies start taking some height, I've improvised a "Gradual fixture" for the supplemtal light (still need to figure our a reflector for that) using a 4 bulb vanity fixture.

-the cheap MIC LED panel came in a couple of days ago, I figured might as well put it to use while it lasts. Oh yeah, the seller shipped the wrong panel too, I was bidding (and won) on a mixed red & blue panel, when I got was an all blue panel...

So be it, I'm adding it to my vegging cycle. Extra blue spectrum for under $25.00, and for a cheap made in China panel it's still pretty freaking bright!

Here are a few pics of the setup as it currently is, right now I'm testing for temperatures; I have a grand total of 204 watts of mixed CFL and LED going on, if the temps stay in the 25 - 26 degrees Celsius, I'm laughing!

:hippy:

Pedro de Pacas
08-31-2008, 05:37 AM
With all of the on the spot modifications I've made to my cab it'll be no small miracle if my plants don't all turn out hermies from the stress! Anyway, after the temperature test I returned the plants to the cab, readjusted the lights to one 125 watter + one 45 watter and the blue LED panel.

I also decided to switch back to a 24/0 light schedule: with all of the moving the plants around to modify the wardrobe I wanted them to 'bathe in light' as it were.

Just came back from shopping and the cabinet temps are stable at 80 F...the air intake and exhaust fan are doing their job! :thumbsup:

Pedro de Pacas
08-31-2008, 05:20 PM
Repotted the plants today ... told ya you'd get a good laugh out of the new pots! ;) they're 8" X 8" and I kept the soil about 6" deep in them. At $1 a container it was hard to go wrong.

I doubled them: the bottom container is the drip tray and I poked holes at the bottom of the top container to allow drainage. This is what the inside of the cab looks like now, still on 24/0 lighting and trying to get the most out of the space available!

I debating whether to try a scrog or not...I mean I grow from seed, what if one of the babies turns out male?

:hippy:

With all of the stress the babies had to put up with I figured it was time for a feeding...and this time I made sure I used the proper proportions to avoid a repeat of the nute burns I got 2 years ago...

My watering can holds 4 litres, the plant food needs to be diluted 4ml/litre = 16 ml of plant food for the full watering can. On a 24/0 lighting schedule and a re-pot, nutrients won't go amiss. I use a 20-20-20 plant food for vegging & diluted molasses for blooming.

Definitely a Dollar Store find! ;) The cool thing is that once the 150 watt HPS system I got is delivered, I can pretty much use it for both vegging & blooming!

The CFL's and current fixtures aren't lost, y'see, in the event that one of the babies turns male, it allows me to seclude it, collect its pollen and selectively fertilize one bud so I can collect my own seeds for the next grow! Agreed I'll have to figure something out for the "seclusion chamber" ...

Pedro de Pacas
09-02-2008, 06:31 PM
Awrite, the Oasis babies seem to agree with the 24/0 light schedule:

the stubby one with heat damage (remember the home made fixture that fell apart? It kinda fell on it! :( ) seems to be repairing itself quite nicely,

Leggy #1 and #2 (the one with the second sprout that I thought was dead & grew anyway) have grown bigger an healthier,

KC seems to be getting a bit more height (though the lower leaves were showing signs of yellow, I'm hoping the feeding I gave them yesterday will help that);

And the little baby in the same pot as Leggy #2 is developping nicely...not sure if the seed is one of the KC 36's or Oasis that weren't germinating...but I don't dare move it at this stage.:hippy:

Tried an experiment yesterday...since the plants can benifit extra Co2 on a 24/0 schedule, I tried this:

Turned off the exhaust, and lit up one of those 10" incense on a stick inside the wardrobe (planted it in the soil of Stubby, which has the most free space) and let it combust for 30 minutes.

Agreed, it released equal parts of CO as well as CO2...and the temperature shot up nearly 10 degrees, and the humidity went up about 2%, but... (and maybe it's just my imagination)

The leaves on all plants seem to have grown this tiny bit fatter, Jr definitely is growing new leaves (then again a 24/0 light schedule will do that too, and I did feed the plants a few days back).

As well, the added vermiculite & perlite is doing a fine job in preserving moisture in the pots; I haven't had to water the plants since I fed them!:thumbsup:

Pedro de Pacas
09-05-2008, 04:01 PM
Got notice of delivery of the HPS light today! :D I can't wait to compare the results...general consensus seems to be that HPS lamps have better light penetration, better efficiency, etc... the fact that I'll be using a 150 watter as opposed to a pair of CFL's totalling 170 watts should also help keep cabinet temps manageable...

I'm stoked! :D

Pedro de Pacas
09-06-2008, 05:07 AM
150 watts HPS and blue LED panel (since I'm still vegging at this point) and I can see firsthand what the deal is with HPS...OMG is that ever bright! Inner cabinet temps are at about 83F (after 8 or 9 hours uninterrupted) and the humidity is around 63%.

It was a bit of a challenge to install the remote ballast outside of the cabinet, but I figured it out. It is lukewarm to the touch, out of curiosity I placed a thermometer near it and it reads just under 73 F...

So far so good, and the babies seem to like it! :thumbsup:

Pedro de Pacas
09-07-2008, 09:42 PM
At the suggestion of the love of my life, I lowered the light to about 2' above the tallest plant to concentrate more light on the babies...I also added a Glade plugin gel near the exhaust fan.

While the smell is nowhere near the smell of ripening females, the 'green smell' is still noticeable, and I managed to find a bunch of plugin gels for cheap so I thought I'd give it a try.

I read on another board that adding ground charcoal (about 1" to the soil) can help control grow room odors too...I have to wonder what that would do to the plants though!

At any rate, this is what the cabinet and plants look as of today:

Okay, decided to initiate 12/12 earlier today. It may be a bit early for the Oasis plants but the KC36 has been vegging for 6 weeks.

The dark cycle seems to be agreeing with the babies (then again this may be an optical illusion!) as they're looking bigger already...we'll see. Since marijuana plants can double in size during flowering I might as well do it now.

Yeah, I'm nuts for doing the 12/12 before sexing...but hey, come what may.

Then it sounds like my instinct was right! This is my first time flowering with HPS and LED for extra blue spectrum (okay, so I might not need it during flowering...but a bit of extra light can't hurt! ;) )

Thanks! I'm learning more and more at every grow!

My concerns about HPS lights were unfounded: the 150 watter generates less heat than the combined 170 watts of CFL's I used for vegging, the ballast generates less heat than I expected (it gets lukewarm at worst - the 125 watt CFL was so hot when I took it out I nearly burned myself, so no worries there!) and I use less electricity... lesson learned!

If all of the things I've read about flowering with HPS are true (denser buds gorged with resin), I can't wait for the end of October! :D

Okay, here's what the babies look like after their first 12 hour dark cycle...might be wishful thinking but they do look bigger, including Jr (the one sharing the same pot as Leggy #2 (though at this point Leggy #1 & #2 aren't leggy any more! ;) ).

I pruned 2 leaves off Leggy #2 to allow more light on Jr. Since they haven't shown any sign of sex yet, I figured it woulnd't have adverse effects on Leggy #2 (not yet anyway).

Raised the light one rung - a few fan leaves were burned. Did some pruning and watered the plants...gotta be mindful of that "light circle" as the plants get taller and closer to the light; the heat increases as the leaves get closer!

Pedro de Pacas

No burns on the leaves this moring, but to be safe I did the 'hand test' at the top of the tallest plant; and the heat felt a bit uncomfortable so I raised the light a few more inches.

I turned Leggy #2's pot around so Jr gets better light exposure (gotta love the names I ended up giving 'em! ;) ). So far KC is still the tallest at 11" , Leggy 2 is second at 8.5", Leggy 1 is third just a smidge above 7", Stubby lives up to its name at all of 4" (considering I wasn't sure it would survive the original light fixture falling on it and burning it badly) and looks much healthier than it originally did (to my relief).

Last but not least, Jr is expanding nicely (sprouted several weeks after the rest, go figure), not very tall (1" if that) but the leaves are getting nice and big. Latest pics!

Pedro, Very Nice Log.

Couple quick questions though. What was the temprature increase when you switched to the 150 watt HPS. It seems you are running in a closed 3x3 room if im not mistaken.

Pedro de Pacas

More random thoughts:


This is day 5 since inducing 12/12, the plants should be showing signs of sex in the next few days. I do believe I see hints of white on KC, but I can't really stick my head in there close enough to see if those are pistils or not.
I have plenty of flat white paint leftover from another project of a few years ago, but I fear that sticking the babies in there as the paint dries would harm them, so that's out.
The flat white cardboard makeshift reflectors may or may not be helping, it's hard for me to tell as I have nothing to compare it to. I have found a good supply of emergency blankets for a buck each, same place I found the popcorn bins. 70% reflectivity is better than nothing at all, and if I read my research right, hot spots shouldn't be much of an issue under 150 watts of HPS - if I'm mistaken somebody tell me!


Perhaps I should research flat white cardboard reflectivity? According to the Ask Ed column on Cannabis Culture, some Hydroponic growers use it...but how reflective is it as opposed to flat white paint, mylar, emergency blankets and aluminum foil?

Missed your question as I was posting!

Plenty of variables but overall the temps are actually a few degrees cooler after switching to the 150 watt HPS. Keep in mind that I was using one 125 watt CFL (nearly burned my hand trying to unscrew it from its socket too - I couldn't wait to let it cool off) with a second CFL (a 45 watter).

We're talking 170 watts of CFL with built-in ballasts, and the ballast is where the worst of the heat builds up. Does the HPS bulb generate heat? Absolutely, but the heat buildup is actually less since it uses a remote ballast, which is kept outside the wardrobe.

The measurements of the wardrobe are 22.75" X 19.5" X 5'4" give or take. Said wardrobe is near the room AC which keeps the outside temperature in the low 70's while the inner cabs temps hover around 82-84 F with the humidity around 58-64%.

Even after adding the exhaust and passive air intake the temps used to be in the 86 -92F range with the two CFL's, so yeah, no regrets since the switch!

I decided to take a chance, I used one of the emergency blankets and lined the wardrobe walls & door. I removed the cardboard (whaddya know? it was warping!) as well as the blue LED panel. At this stage I want the babies to show sex, so the more reds the better.

Here are pics of the grow rooms as it is as of today, the babies and close-ups of KC...6 days into 12/12 and I still can't tell if it's a girl or not!

09-14-2008, 04:55 AM
Lemme know how yours turns out too! Chit meng, the blanket came loose in some spots due to the suction from the exhaust fan :mad: the blanket's touching the plants in some spots :mad: aluminium foil tape is garbage!

Looka lika I'm gonna have some refixing to do tomorrow, I don't want to expose the plants to my green CFL for too long. I did stick the LED panel back in there though...more lumens won't go amiss.

Pedro de Pacas
09-15-2008, 04:07 PM
Feeling a bit impatient for the babies to show signs of sex...seeing that KC's 9 days older than the others I took a few close-ups of various possible bud sites...the leaves are showing small bumps reminiscent of trichomes (very tiny) and I am seeing whiteness but I'm not sure if that's due to new leaf growth or if I'm actually seeing pistils...I know, patience is a virtue...and with today being the first day of week 2 of 12/12 I don't feel very virtuous! ;)

Pedro de Pacas
09-16-2008, 05:15 AM
And the growth spurts have started! Again, I didn't want to expose the babies to my green CFL for too long, but I just raised the HPS a few inches: Leggy 1 has just decided to grow like crazy, it is now the tallest in the wardrobe, I'd say about 1" taller than KC that had been the tallest up until today...this is becoming interesting!

It took 8 days of 12/12 but things are beginning to move!

And thus far the unofficial count is: Females 2 , Males 1 and 2 still unsexed.

I've located pistils on KC and Leggy 2, balls on Leggy 1 (though one pod has a white spot on it, I might be looking at a hermie or a mis-shapen female) and no sign of sex on Stubby or Jr.

I'll take photos later today. If my assessment of Leggy 1 is accurate I need to seclude him. In the past I would have snipped him off and given him the heave ho; but I want to collect my own seeds this time around. The Oasis seeds are a bit pricier, so it only makes sense to collect the pollen and try to fertilize one bud at least. Leggy 1 is definitely from one of the Oasis seeds...

Pedro de Pacas

More random thoughts:

-I can't take closeup shots if it saved my life, in spite of owning a decent digital camera...so I'll just have to rely on my past experience to say I have 2 females so far and one male

-The big growth spurt occurred the monday following my adding a Bionaire Tower air purifier with optional Ionizer to the room in which the grow wardrobe is located; coincidence? I keep the Inonizer setting on to help further reduce odor; but I have seen articles claiming that negative ions may enhance plant growth...like I said, it might only be a coincidence but regardless, I'll keep using it!

-The glade gel plug-ins are helping with odor control, but I still get "that green smell" when I come home from work. My attempts at making a DIY carbon scrubber have been an exercise in frustration thus far. Y'see I'm all thumbs; might be a green thumb but all thumbs nonetheless! ;)

I seem to recall something about Pinesol being a good odor absorber; I'll have to look into that. Secluding Legs (might as well call him "legs" since I know it's a "he" ;) ) will be a challenge too...:wtf:

Pedro de Pacas
09-18-2008, 03:55 PM
Rubbermaid to the rescue! I needed a way to isolate the male and collect the pollen, so one of those big Rubbermaid garbage cans on wheels was just perfect! Told ya I'd still have a use for the CFL's and timers I'd purchased over the past 2-3 years!

Pedro de Pacas
09-18-2008, 04:05 PM
I still can't do a closeup to save my life, but here are the pics as of this morning. I've seen pistils on KC and Leggy 2. I'm hopeful Jr will also turn out female but it's still much to short.

Stubby has recovered quite well from its close encounter with the 125 watt CFL from a few weeks back, but I fear the stress is turning it male... a shame. It's still too early to tell in Jr and Stubby's cases, so I'll give them a bit more time.

My idea of using diluted Pinesol in a Rubbermaid measuring cup has been working well so far...keeping my fingers crossed!

Pedro de Pacas
09-19-2008, 05:59 PM
A few closeup pics of Leggy 1. It's still too soon to determine the sex of Stubby & Jr, originally I thought Stubby was edging towards being male, but I'm no longer sure.

Keeping my fingers crossed that the final tally is 4 girls, 1 guy and 1 bud site pollinated for seeds!:hippy:

Pedro de Pacas
09-21-2008, 03:40 PM
Pistil spotted on Stubby! Late bloomer (pardon the pun) but that brings the tally to 3 girls, 1 boy and one left to determine (though at first glance it's looking like a 4th girl - keeping my fingers crossed! :hippy: ).

Mary Jane is indeed one tough plant: after the mishap I had last month with the DIY light fixture nearly killing Stubby, I expected it to turn male...it's a girl! :thumbsup:

And I have a new found respect for Dutch Passion seeds. I'd read they have the most reliable genetics (they boast the Oasis breed as being almost spidermite and mold resistant if I recall), well, Stubby is certainly a glowing example of those great genetics!

KC and Leggy 2 are develpping almost pom-pom looking young buds. Which brings the question: when do I start counting days to harvest? 55 to 60 days would workwell with both the KC36 and Oasis plants, but do I start counting from the day I initiated 12/12 or from the day the last plant showed signs of sex?

Like if Jr shows pistils by next tuesday, does this become my "day 1" of flowering, or was Day 1 when I initiated 12/12? Just trying to be clear...:confused:

Pedro de Pacas

Abd the official count: 4 girls and 1 boy! I'm a bit worried about Leggy 2, she's shown several limp leaves this morning...

I did a bit of pruning and will research "limp" on the forums...I think I know the cause but I want to be sure. Unless I'm way off, limp leaves are due to over watering, but the soilfelt bone dry, almost crusty even!

Far out! I wasn't 100% clear of when exactly the flowering period starts, and Ed Rosenthal already had that answer in his "Ask Ed" Column:


Flowering time begins when the light cycle is reduced and lasts until ripening.

Which means I'm a good 2 weeks & 2 days into flowering already! Or 17 days...avreage flowering time is 55 to 60 days, so 43 days to go give or take! :thumbsup::hippy:

Pedro de Pacas
09-25-2008, 03:19 AM
Hmm...KC Brains has a 6 to 8 weeks flowering period for the KC36 whereas Dutch Passion has a 8 to 9 week flowering period for the Oasis strain. So the girls could be ready as early as 42 days or as late as 63 days, so the 55 to 60days period seems to be pretty much in the zone.

Late October would seem to be the overall target for the harvest, which is perfect since I might have some out of town visitors in November and I'd really like to have the grow-op put away for mid-November.

I water cure, so it takes care of any odor, and I have some good stash places to put the grow stuff & weed & accessories away without raising suspicion...

One day, mj will be decriminalized and all of the cloak and dagger won't be necessary any longer...until then, stealth's the word! :Tomcat:

Day 18 of flowering...had I paid better attention I would have seen that Legs already had a few pollen sacks that had burst open from a couple of days ago! :wtf:

Found a clean container (a recycled pill bottle) gently tapped the open sacks above it, collected the pollen, washed my hands...

took Stubby (who's pretty tall by now) out of the grow cab and pollinated one of the lower buds best I could. I then dusted off the pollen from the lower leaves (to avoid it pollinating the other girls when I return it to the grow cab) and returned Stubby to the wardrobe.

So...I'll either get no seed at all, seeds on the one bud I targeted or seeds all over the place because I missed some pollen and it'll fly around with the cab ventilation...

So best case scenario: I get big, resinous seed -free buds on all bud sites but one! :greenthumb:

Cut up Legs and sent it to the trash. I recuperated as much soil as I could, and put the makeshift Rubbermaid isolation cab away. And now...I wait as the girls bloom and ripen! :D

Pedro de Pacas
09-26-2008, 03:01 PM
Day 19...resisting the temptation to overfeed or overwater, and resisting the temptation of adding a few extra low-watt CFL's to the mix...part of me feels the extra light wouldn't go amiss on the blooming girls, but my meagre experience tells me I'm asking for crispy dry leaves and heat damage if I do...

And the girls are looking fine, so I'll have to learn to leave well enough alone! KC is 20" tall (and seems to have stopped growing at that height), Leggy 2 tops her at 20.5 -21" tall, Stubby has had the most remarkable growth spurt, from being short and heat damaged and now standing tall at 17" of height!

Jr...I don't even see her any longer: too much of a canopy from Leggy 2 and KC hogging a lot of the top, all I can do is hope that its small buds get enough HPS light to fully bloom, even if it is only 4" tall (or at least it was last time I could actually see it!)

More to come!:hippy:

Pedro de Pacas
09-28-2008, 08:33 PM
Day 21 of flowering and the girls are looking good! Found me an inexpensive SMT pure red LED light from ebay, I'll focus it on the lower branches. Since marijuana is a light hungry plant, extra red spectrum won't hurt...as long as the salesman sends me the right color this time around! :rolleyes:

Regardless, the switch to a 150 watt HPS is making quite a difference from the prior 100% CFL getup... here are the girls as of today:

Pedro de Pacas
09-28-2008, 08:36 PM
A few more bud sites...sweet!

Pedro de Pacas
09-30-2008, 06:19 PM
No photos yet, the bud I pollinated on Stubby is showing tiny balls through the pistils (which are turning brown)...mission accomplished? I'm hoping that those tiny balls are seed pods and not pollen sacks :wtf:

I'm still unclear on what my nute schedule should look like, I had so many bad experiences with nute burn in the past that I might be underfeeding? As it stands I water every 3-4 days (when the soil is dry) and I've fed the plants once during vegging and once thus far during flowering.

I'm trying to steer clear of the chemical ferts (a 20-20-20 mix) as much as possible and want to use diluted molasses to keep flowering as organic as possible, the only question is: how frequently?

Pedro de Pacas
09-30-2008, 07:11 PM
Okay, looks like I found answers to my questions! From what I've found on this site, nutes can be given to the girls every third watering. I watered them last on Sunday, which means the soil should be dry around Thurdsday; plain water again.

Next watering after that should be around the following Sunday, so I'll give the girls another shot of diluted molasses then. 3.7 litres per gallon, my watering can holds 4 litres filled to the top, so my concerns about using too much molasses the last time were unfounded.

So...awaiting the delivery of the SMT pure red LED light...supplemental red spectrum and no extra heat won't go amiss. Agreed the HPS should be more than enough, but according to what I've been reading in the Grow Logs, there's no such thing as too much light! ;)

Looking good pedro. Nute's are hard to buckle down, you kind of have to get used to a niche yourself. Theres a great sticky somewhere with a shitton of images about what nutrients cause what appearent damage to your plant. I'd check that out to make sure you arent overnuting them then just slowly increment your nutes till they grow great and dont have any signs of nute burn or deficiency.

I cant seem to find the post maybe it was of the growFaQ i dont remember but it exist.

I take it your using MG or something of the sort for soil. IF this is the case they usually have nutes built in that you have to account for. Just makes sure you got your numbers straight and btw

Why thank you! :D

Believe you me I've made plenty of mistakes in past grows, overfeeding the plants rsulting in nute burns, heat burns from too many CFL's in a small cabinet (that was before the wardrobe) you name it!

I use the Plant Prod(the 20-20-20 mix from Home Depot) once during vegging, and that heavily diluted, split between the original four pots. The label says it's also suitable for flowering and blooming I guess I could make a super potent nute cocktail using that (maybe at half dosage) and a molasses boost...I'd like to keep the bloom ferts as organic as possible...:wtf:

Okay, more pics! Foliage was beginning to interfere to the point the girls were competing for light so I pruned the excessively large leaves. I may be wrong, but trimming them up a bit will help get more light to the lower bud sites as well as improve air/Co2 circulation in the cab.

I've done such prunings in past grows and got no hermies so I'm pretty sure the girls are safe! ;) To help alleviate the stress (and since the soil looks pretty dry - three days after the last watering so I'm within this grow's average) I figured it wouldn't hurt to give them a feeding.

Very, very low dosage, maybe a quarter of the 20-20-20's recommended dosage and a teaspoonful of molasses diluted in a gallon (4 litres) of water, split up between the girls.

Here's how they look after their haircuts, and a closeup of the pollinated bud...are them seeds I'm seeing? ;)

Day 25 and I measured the plants for height:


Stubby is now 20.5" tall
KC is a few hairs taller than 22"
Leggy 2 tops them all at 2'1"
Jr is hanging in there at 7"...hopefully yesterday's pruning & feeding session helps her get bigger and stronger.


I raised the HPS light to accomodate Leggy 2's stature. Which means I had to move the inner cab fan to the wardrobe's floor (blowing air at the bottom of the girls rather than at the canopy).

Waiting the the pure red SMT LED bulb with great anticipation...maybe I'm reading too much into that whole extra red spectrum deal, but I want to see thick, dense nugs this time around instead of fluffy, frail buds.

Don't get me wrong, the "all CFL" Mango and KC grows from the past gave me potent buds indeed...but compared to the "Squamish Gold" (I call it that because my brother's pal who was a grower was originally from Squamish BC) my kid bro had me try 2 years ago the CFL bud was still pretty mild!

Pedro de Pacas
10-03-2008, 03:49 PM

Like I've been told once: the devil's in the details, and with a bit of digging; it's possible to have a decent personal grow on a limited budget.

Okay...in my meager experience here are my suggestions:


Lookup the LST - Topping and Fimming posts on this site - my first grow had limited height; I controlled the canopy height low by gradually bending the branches and keeping them low with pieces of string (my version of LST)
Carefully monitor the cabinet temperatures, extremes in the too cold or too hot aren't good for the plants
Be careful not to overwater or overfeed - I lost a raspberry bush (actual raspberries ;) ) to root rot because of over watering (a soil moisture meter helps); and nute burn can harm the plants too if you overfeed.
Try the "hand test" to be sure the lights aren't too close to the plants
Lookup the article on fans (I posted the link earlier in this log) to calculate proper air exchange in your cab...


Hope this helps! :hippy:

yea it helps tremendously i just picked up some nutes from my local plant place. its called green light all purpose 20-20-20 plant food which the guy said works well for any plant. so basically with the LST method you are basically controlling the height. and is using all cfls gonna give me an alright yeild? sorry for asking so many questions. but yea my box seems to stay really cool and the lights are about 3-4 inches away from the plant. they are looking really good. i have em in the big QT cups its like a 54oz cup. which is pretty big. and my plants are about 2 weeks in when should i start flowering.

Yield depends on many factors: light intensity, watering/feeding schedule, air circulation (we wouldn't last very long in close quarters without proper ventilation right? ;) ) cabinet temperatures, plant genetics... :hippy:

I got bud on my first grow (2 KC Brains Mango under 2 warm white 45 watter CFL's), the "high" was decent; but was the yield and bud size comparable to what I would have gotten with a 150 watt HPS? Probably not.

I tried growing on my balcony even...23 floors up, no chance of the neighbours seeing leaf shape...lost 2 Mango's there: too much wind, not enough sun (nothern exposure) so as you can see I made plenty of mistakes. :(

There was a Low Ryder grow between the balcony grow and the first Home Depot wardrobe grow...never reuse soil that spent the summer outdoors...spider mites! :jawdropper: Ever seen cobweb covered bud? :wtf:

Later, I got passable yield using a 125 watt high powered CFL (the first Wardrobe grow - leftover Mango seeds and KC 36 seeds), hoping that the one CFL could handle vegging and flowering...big mistake! While it is very powerful, the lumen output was far from sufficient, and ventilation in the wardrobe at that point was mediocre at best.

Did I get bud? Absolutely. Did it look as good or as big as my current grow? Nowhere even close!

All of this to say that you will get bud. If you're careful you might even get better looking, more potent buds than I did, it's a learning process you see. :hippy:

A few more tips though: Cool white works better for vegging (which you probably already know) and warm white (soft white) works better for flowering. Before you initiate 12/12 you might want to make sure you have warm white CFL's in there and that your babies are LST'd (or LST as you go along, be gentle while bending!)as they can litterally double in height once blooming has started!

As far as when to initiate 12/12, well...

Some growers believe in vegging 24/0 (or 18/6) until the plants are 12" tall before initiating flowering, others like to wait uintil the plants show signs of sex; others prefer to go 12/12 from seed and still get wonderful results, so when to start flowering is strictly up to you.

For my next grow, what I might do is sprout the seeds using my usual method (soak the seeds 8 -12 hours in warm, sterile water in a warm, dark place), plant the seedlings in styrofoam cups under 24/0 cool white CFL; once the seedlings are a few inches tall, transplant in bigger pots and go 12/12 right away; when growing stealth, time is always an issue, which makes initiating 12/12 as early as possible attarctive indeed IMO...

yea i found a great deal for a 250watt hps kit which is gonna run me bout 160 which aint bad. but like you said i will get bud but just not as good as it could be. but yea im runnin 6 26watt cfls and its puttin out like close to 9grand of lumens a peicelol. but until i get my hps my trutsy ol cfls will have to do.
but on the flowering my biggest plant is close to 4inches could i start flowering like next week if i wanted and still get a good size plant and a decent yeild? so you said the yeild quantity is decent.
when would be the best time to tell the sex of the plants.

Quoth bickeybammer:
its never to early to flip the lights... i have 4 purple erkles that are 12/12 from seed and all 4 came out female..... i have a purple voodoo and g13/hashplant and 12/12 from seed that came out females.... but the only plants (besides my clones) that i didnt 12/12 from seed came out to be 1 female and 13 males ... BAH .... o well

If you veg the "traditional way" sexing can take 6-8 weeks. Inducing flowering forces them to show sex earlier.

Pedro de Pacas
10-05-2008, 04:53 AM
so you think that 250watt hps would do good

More light is good as long as you keep a few things in mind:


If the HPS kit doesn't come with a timer you'll need a heavy duty grounded timer to stay safe (using a 2 prong timer with the remote ballast may result in a fire).
Measure how much space you have between the top of your enclosure and the plant canopy, is there enough space to accomodate the HPS fixture and reflector? If yes,
How much space does that leave you between the HPS bulb and the top of the plants? A HPS bulb too close to the plants can cause severe heat damage.
You'll need to figure out a way to install the remote ballast outside your grow cabinet to keep cab temperatures manageable;
You may need to incease your cab's ventilation after the HPS switch (proper ventilation is a good thing anyway);
Always use a bulb that matches your ballast - with HPS/MH you can't mix and match;
While a fire is very unlikely here are a few things to keep in mind to avoid one - always use the appropriate timer, always use the 250 watt bulb with the 250 watt remote ballast and beware cracked bulbs - most HPS fires are due to a cracked bulb exploding upon ignition.

Gave the girls a watering - Sundays and Wednesdays seems to be the ad hoc watering schedule. Which means I'll have to shift the schedule by one day (I'm off with my girl for the long weekend! :hippy: ) so that the little ladies are watered before we leave and won't be in too rough a shape when we return.

To prevent heat burn I'll raise the HPS light maybe 6"? I have memories of last year's wardrobe grow, and how one of the KC 36's had gone through a growth spurt while we were gone and sustained major CFL heat burn (it was litterally touching the bulb!). At this point the plants should have done most of their growing but I don't want to take any chances!

Usually the plant stretch the first 3 week when flip to 12/12, in these 3 weeks you can see them grow 1 inch per day and even more. In you're case at day 28 you should not have any problem. Checking the FAQ's you can see the chart : Flourescents: proximimty, 400w HPS: 1 foot, 600w HPS: 1.5 foot, 1000w HPS: 2 foot. So any lamps less than 400w 6 inch should be perfect.

And we're nearing the halfway mark for the harvest folks! Well that is if the girls are nice and ripe in another 30 days. It would seem that different strains ripen at different rates, the KC 36 may be ready a good week earlier than the Oasis, so...keep your eyes open, trust the plants as well as the calendar. Snip a leaf when you're in the 50 day range and inspect it under the mini microscope for trichome color.:hippy:

Speaking of trichomes, the tops are showing more and more of them, not quite the 'frosty' look yet, but getting close to it anyway. Once again, my skills at taking closeups leave much to be desired, the tichs aren't really visible at this stage...which is weird 'cause I see them with the naked eye! ;)

Big PS for day 30: the SMT LED bulb has just been delivered! :D And give credit to the seller, he did send the color red! ;)

As far as intensity goes...maybe I'm still thinking in CFL/HPS terms but it's not the 'red spectrum bath' I envisioned...oh well, it may help or do nothing at all, so I'll keep a positive attitude and hope the extra reds will help the few budsites closest to it...:greenthumb:

Watered the girls thoroughly before the long weekend trip and inspected the girls, this is indeed the second half of flowering as some pistils have begun turning brown...nice! The trichs are visible to the naked eye and while they're not yet showing "that frosty look" it's definitely on the way there! :D

Pruned a few leaves again, mostly at the bottom of the plants to improve air flow and got rid of a few leaves that were showing signs of drying. All in all the best grow yet! :hippy:

Regarding your leaf problem my knowledge isn't all that great, try here, there are many people more experienced than I am that can be of assistance ;) :

Plant Problems - Cannabis.com Forums Message Boards - Medical Marijuana, Cannabis Club, Dispensary, News (http://boards.cannabis.com/plant-problems/)

Like I've mentioned before, if you have limited height you really should top and/or LST to control plant height, as the plants can litterally double in height during flowering, and you want to stress the plants as little as possible during flowering (thus Low Stress Training).

Keep in mind that I'm by no means a leading authority on indoor/stealth grows, my own experience comes from a lot of trial and error: my first Mango grow would have been so much better had I had invested in a HPS light 2 years ago (then again an affordable 150 watt HPS kit was hard to locate back then); and if I had eased off on the plant food (mega heat & nute burns).

The point I'm trying to make is that therere are many growers in this Community who are far more experienced than I am, look around, ask around; for all I know I might be handing out bad advice, and I'd really hate to learn your grow went to hell because I gave you the wrong advice! :hippy:

Just returned for the road trip & finished unpacking. This is the first time I'm watering the girls and trimming dry leaves under the green CFL. I've noticed one seed pod on the bud right behind the one I pollinated on Stubby...oh well, more seeds for future grows and the rest of her buds look fine.

I'm not sure if it was due to the stres of the DIY fixture nearly killing her as a young plant, but Stubby has developped into this "V" shaped plant with dual Colas, without topping...Mother Nature sure holds many surprises!

So yeah, I can pretty much say the growth spurts are done with:

Leggy 2 is still the tallest at 2' 2.5" (or thereabouts)
KC is still second at 22.5"
Stubby's tallest cola is at 20.5"
Jr seems to have gained a bit more height...nothing earth shattering but she's 8.5" tall as of today!

The trichomes are definitely becomming more and more visible, even under green light. I'll have a better look tomorrow morning when the light cycle is in effect.

Random thoughts:

I can see definite differences between the past all CFL grows and the mixed grow using CFL, LED and HPS. At best, under the all CFL lighting I would get many small "pom-pom" buds. Since getting the HPS, I am seeing some mighty large tops in the making, where the cola "meges" with the buds beneath it...Leggy 2 is showing signs of this.

Looks like this'll be the first time I get bud that looks like the ones advertised by KC Brains and Dutch passion! :thumbsup:

According to their own photos, KC-36 and Oasis should look like this when ready:

Male: they'll grow pollen sacks. Unless you wish to selectively pollinate a bud or two to have your own seeds (which would entail you isolating the male from your girls) or if you don't mind having seedy buds get rid of the male ASAP! :eek:

Female: you'll see pistils (they look like small, feathery white hairs).

FWIW I was on the fence about stubby - with all the stress it endured I wouldn't have been surprised if it had turned out male or hermaphrodite (balls & pistils - you can find pics on this web site if you do a search)...so I waited and to my relief, Stubby's a she!



The girls look great ! Yes we do see trichomes !

Thanks! I'm going to eyeball it as far as flowering goes...'the zone' seems to be 55 to 60 days, maybe longer or sooner depending on strain (if I recall, KC36 has an average flowering time of 6 to 8 weeks, while Oasis can take up to 9 weeks).

So I'd say as soon as they look close enough to the pics I downloaded from the KC Brains and Oasis web pages, hopefully in 55 days...I know, I lack the virtue of patience! :p

3 to 5 days after initiating 12/12, though Stubby and Jr took closer to 10, so it may vary from plant to plant. I'd say 5 days is average?

The tops are beginning to show "that frosty look" but I'm still ways from harvest time. Some buds are getting close though...:thumbsup:

Watered the girls, gave them another haircut and examined a leaf under my pocket microscope: the trichs are still in the "clear to milky" phase, harvest time should be around the "milky to amber" phase. ;)

Now I know my skills at pollinating are still in their training stages: I've spotted seed pods on buds other than the one I pollinated on Stubby, Leggy has one and so has KC...a KC 36 plant pollinated with Oasis pollen, that'll have interesting results!

So as long as I have seed-free bud as well as seeded ones I guess I'm ok, and I'll be saving money on future grows with the 4 pollinated buds! Okay, I can't help myself here's some pics!

A HPS is not a cost it is an investment that pays for itself first grow you use it.
I mean if you get just 1 ounce extra both the cost of the light and the extra electricity is for free. And 1 ounce any grower would get extra changing from cfl to HPS.
Even if you will not sell any it is still money you don't have to spend.
Another gain is that the grow is faster with HPS. You save a week or two in veg and probably about the same in bloom.
CFL is great for ops where temperature can be hard to control, they won't save you any money though.

Dude, if that's the case I should be ready to harvest either this weekend or next weekend: flowering time is 6 to 9 weeks, I'm well past 6 weeks going on 7... if the HPS really cuts a week or two from flowering I should be done soon!

If it says 6-9 weeks it's probably 8-10 ;)
And they count from actual start of bloom, not switch to 12/12.
They wanna sell those seeds and there is a lot of competition.

Watch the movies from Green House, one of the most serious seed banks out there. In their grow videos they always say now you can harvest for commersial reasons and that's what we print about the strain but we go 2-3 weeks extra for quality.

Anyway, if you wanna harvest at ambre I am sure you will cut 3 weeks minimum seed to harvest with the HPS. I did some tests for veg and those plants took almost 3 weeks more to 40cm. Cloned from the ones that made it faster. Both in coco and same nutes, only difference was I used my Bloom HPS the fast time and my Veg! CFL the slow time.
Hell the HPS pays for itself even before you switch to 12/12 hehe.

Anyway in comparison there is no way you save money by using CFL over HPS. There can be inviromental reasons CFLs are better used but those two compared it's cheaper to use HPS.

No pics today but I'm glad to say the girls are ripening nicely. I used to be a big proponent of CFL grows, but I can see firsthand what the deal is about HPS lights. Agreed my grow setup has changed many times in the past two years, so figuring the HPS that's "just right" for my needs would have been difficult...

But after doing my homework this time around, I'm left wondering how on earth I've managed without a HPS light!:thumbsup:

Don't get me wrong, using CFL's was good learn the ropes of growing and they definitely have a place for young sprouts and vegging, but for floweringl there's no comparison!

Word.

The main thing people are missing when growing is what plants actually need and are made up of.
It's easy to think that it's all about sufficient light and then its all about best nutes.
Not true!
The overwelmingly biggest nute a plant can get is CO2 because they are mainly made up of carbon like all living things (not counting water but water is a distribution medium not plant matter) and for a plant ALL of it comes from the air.
So everything we do is to make it easier for the plants to "eat" more CO2 from the air, how?

Nutes: Are important because it adds stuff needed for that process to take place but you cap a plants nute uptake very easilly.
Light: The more light you add the more CO2 a plant can use. So thats why more is always better if temperature is ok. You can cap light also but not very easilly.
Fresh air: Together with light something you just can't get too much of more or less. Every grow room should be viewed with this in mind.
How does your air move through the room? You want fresh air to come in low, move to the centre of the plants and THEN get sucked up through the canopy. Try to keep exhaust intake central in a position to make this possible. I use computer fans at the intake to get the fresh air fast into the centre of the room before heat and exhaust fan drags it up through the canopy for exemple. In a system where CO2 is added other rules applies ofc.

Anyway... The by far most important thing for good yeilds and quality is to make it possible for the plants to keep this process going as good as possible and that you do by realising that light is more important than air circulation which in it's turn is more important than nutes.
Both light and CO2 supply are bottle necks, nutes are not. It's very easy to give a plant enough nutes.

Your HPS made your bottle neck much wider and thats's why you see those results. It's all about widening those bottle necks. :D

Sorry for the rambling, was bored and kinda like writing hehe.
Really looking forward to your results m8, good job.

Both light and CO2 supply are bottle necks, nutes are not. It's very easy to give a plant enough nutes.

Your HPS made your bottle neck much wider and thats's why you see those results. It's all about widening those bottle necks. :D

Sorry for the rambling, was bored and kinda like writing hehe.
Really looking forward to your results m8, good job.

And increasing the airflow from 50 CFM to 70 and lastly to 90 definitely widened another such bottle neck. :hippy:

Okay, at least now I know the yellowing leaves are normal at this stage!

Here are some indicators to help you identify that it's harvest time; however, please note that not all of these indicators will appear on every strain.
â?¢ 50 percent to 70 percent of the pistils change color
â?¢ Plants stop producing crystals
â?¢ Plants stop producing resin
â?¢ The fan leaves and lower leaves have turned yellow and are starting to drop off
â?¢ The smell has reached a peak
â?¢ Bud mass has not increased in the past few days

Okay so based on the above, KC and Stubby are about ready I'd say, 52 days after initiating 12/12!

â?¢ 50 percent to 70 percent of the pistils change color
They' re there

â?¢ The fan leaves and lower leaves have turned yellow and are starting to drop off

Yup

â?¢ The smell has reached a peak

Oh yeah...Fabreeze candles anyone? ;)

Leggy & Jr aren't quite there yet, but I tell you what, I forget where I read that flowering lasts an average of 55 to 60 days...under the right conditions, it's so true! :thumbsup:

I can bet you that in 3 more days, it will be harvest time, I'm so stoked! :hippy: I gave the girls a good soak, no nutes. Again, some sort of "pre-flush" in preparation of the harvest! :D

Well it lasted me a few weeks ;)

From what I've learned I could definitely do my next grow 12/12 from seed using the HPS all the way through, as K.I.S.S. as it goes, and cut several weeks of vegging. :thumbsup:

The next (and perhaps only) modification I might do is to paint the inside of the wardrobe flat white, which would avoid the few hot spots the emergency blanket has, mind you I'm debating whether or not I should: the press board has a glossy surface (eventhough it's wood colored) which might be hard to paint...

Otherwise I think I have the optimal grow cabinet setup - 150 watt HPS light with heavy duty timer, 90 CFM exhaust fan rated at 2.5 sones (the air purifier I use for my allergies makes more noise!), nice deep square pots to make the most of the floor space and plenty of leftover Oasis seeds (on top of the seeds I'll get from the bud(s) I pollinated) ... :hippy:

Man, for I guy who used to have preconceived ideas about marijuana I've sure come a long way!

I just scoped one of Leggy's small leaves - milky to amber! And I know Stubby and KC have been ready for a week now, however... I'd like to give it another 24 to 48 hours, get a bit more amber trichs and pistisl...let's make it an even 60 days before harvest...man I hate sitting on my hands!

nice grow!


Thanks! No comparison, this is the best grow yet, and now that I have the right light and ventilation, the next grows will be even better!

Dude that looks tasty indeed.
And plants seem very healthy and lush.
I see red eyes and occasional retardation in your close future hehe.

I don't understand, it's been doing this for the past few days...I can enter smilies manually, but the icons don't work, and the drop-down menu for the attachments isn't working ... :wtf:

Is anybody else having these problems?

More random thoughts:

-I can't take closeup shots if it saved my life, in spite of owning a decent digital camera...so I'll just have to rely on my past experience to say I have 2 females so far and one male

-The big growth spurt occurred the monday following my adding a Bionaire Tower air purifier with optional Ionizer to the room in which the grow wardrobe is located; coincidence? I keep the Inonizer setting on to help further reduce odor; but I have seen articles claiming that negative ions may enhance plant growth...like I said, it might only be a coincidence but regardless, I'll keep using it!


Hey!

How well did Bionaire work for your needs?I was planning to get one to put in same room with my grow. Does it remove smell well?

Nice looking stuff!:stoned:
