[demoreal]

2x2 ebb and flow hydro unit
400 watt light
8 plants

[demoreal]

Setup and plants 1 week veg

[demoreal]

Started 12/12 after 1 week of Veg...
first two weeks of 12/12 used 2ft eight bulb t5 blue light to help prevent stretch...

looks nice bro...i saw your titile and was about to post where's the pics and i figured they wold be following so i backed off and viola...pictures!

never heard of purple diesel....do you know what purps is crossed with the diesel? just curious as there always seems to be something new every time you turn around:jointsmile:

[demoreal]

Thanks!!!

I keep a grow log on Paper. I use a moleskine weekly diary. This grow is comming nice so I decieded to post some pictures and keep a semi-log online.
I am at day 30.
I need to take some shots with a different light.

[demoreal]

Day 30 flowering

Looks great!


Do you air cool your bulb?

[demoreal]

Thats a good question!!!
This is the first grow I am not. I used to air cool my light. I would have the exhaust fan suck threw the light and expel hot air.
I decided to to take the glass off my light.
I was working on another grow with two lights. One was air cooled with a glass the other was not. I noticed (this could be my imagination) better growth and more trichome development under the light with no glass. So I decided to remove the glass from my hood and see if i can keep the temperature in check without it being air cooled. So far so good. I run my lights from 6 at night to 6 in the morning. I like the drop of temperature the plants get early in the morning when the lights go out. Anyway, the temp has had a max of 83 F. It stays in the 70's when the lights are on and in the high 50's and mostly 60's (sometimes 70's) when lights are off. I live in Northern California.

[stra8outtaWeed]

nice looking setup...they call SF Norcal...haha...to us in the way up Norcal we think it ends at Red bluff...haha!

Do you still have the hood sucking air for exhaust because i am sure that will pull some of your heat out from the bulb..but interesting thought on the glass!:jointsmile:

[demoreal]

Yes
I still have the exhaust set up very close to the bulb. In reality I could have left it attached to the bulb and just taken the glass off. I would have done that but my light fit better when I removed the ducting to the hood (this tent is very small). It is still kept very close to remove as much heat as possible.
The truth is I am from So cal, but moved up to Berkeley for school. People here do refer to the bay area as Nor Cal. I am honestly just glad I am away from way down south. There is way to many really expensive trucks down there that I can't afford... With really huge dirt tires that are really clean and never seen dirt...:cool:

[stra8outtaWeed]

thanks for the laugh....i know those trucks...you don't see many up here...we use our trucks :jointsmile:

my moms dad was masters grad at UC Bezerkley....know the place well :thumbsup:

look forward to watchin your grow demo:smokin:

[demoreal]

cool!!!
I look forward to the LED Grow Show.
Might see me with an LED sometime soon. :thumbsup:

[demoreal]

This grow I am happy with the way I pruned my plants. I did some measuring today and the top of my plants are 1 foot from the bulb and the bottom of the buds are 2ft. Lollipoping my plants seemed to work nice. Each plant is growing one, 1ft long bud. Each a perfect distance from the light.
The plants are in 5 1/2 " pots filled with rockwool cubes. The smaller pot size seemed to help with stretch, along with using the blue light the first two weeks of flowering.
I really want to take some nicer pictures.

[stra8outtaWeed]

hey bro...get yourself some Bushmaster in there an no worry about the stretch ever...puts your girls into flower faster and better yield at the end with one application before putting them into flower...martyr has good write up using it in his EPIC BLUE DREAM grow...he has it well documented :thumbsup:

[demoreal]

I own bushmaster. I have used it quite a bit. I only use it in emergencies. It does work really well. One thing I noticed is it seems using it my plants lack quality in the final product. This could possibly be due to the fact that the plant skips the stretch, finishing the plant a couple weeks early. I noticed a slight decrease in quality of final product. I do not like rushing my plants. In my opinion the slower the better. Like Organics. It takes longer yet usually comes out better.
I do use bushmaster only when I have to.
side note: i own gravity and purple max as well. i was thinking treating half my plants with purple max this grow and half not. just to test it out. I use it in every grow yet never compared end results.

[stra8outtaWeed]

right on:thumbsup:

i have the same...purple maxx i think is really good in helping trich development...but gravity is one of those products that sits in the cabinet and i wonder if i should use it or not...i,ve had some issues with it in the past with bleaching out the tops and ruining that nice top cola:wtf:

[LOC NAR on probation]

Gravity. If you have kind of tight buds it will make them rockhard BUT if the strain does not have hard or dense bud. Then it will stress them bad with little to no results. I stopped trying to make fluffy strains rock hard.

[demoreal]

Interesting stuff there.
I think what i shall do then is test the purple max on half and gravity on half of the ones treated with purple max and half of the ones not treated with purple max.
so i get only purple max, gravity-purple max, only gravity.
this will be a nice test.
Thanks guys!!!

"I noticed (this could be my imagination) better growth and more trichome development under the light with no glass."

This is not your imagination. I've had to prove this many times to people by using any simple light meter. Fixed bulb, fixed meter, piece of optical glass from an expensive flat bed scanner. Got the light placed where the meter read 1000. Put the glass in right against the bulb, dropped to about 900. Moved the glass down by three inches, 500.

Glass reflects, after all. :)

[khyberkitsune]

Good info. Thanks!

If you take a clear piece of glass and look at it edge-on you will see the true color. Some are bluish, some are greenish. Many are greenish (like the scanner bed glass, it acts as a green-balancing filter to the scanner) and thus they actually cut down on usable red and blue light while transmitting more of the green light.

do you use gravity regularly? i have a bottle and it scares me...ive bleached too amny tops with it but that was long ago and under HPS and i had no way of raising the light any higher than it was...so maybe have to do my own experiment inder the LED's...does it increase yield with your grows?

great avatar :thumbsup:

[demoreal]

I am not sure about gravity or purple max. I know for sure bushmaster works. You know that too.
I have used gravity and purple max every grow so i have nothing to compare it too.
This grow I will do the test.
2 plants = nothing
2 plants = purple max
2 plants = gravity
2 plants = gravity and purple max

[stra8outtaWeed]

the purple maxx is good stuff and can be used weekly....i do know that...but the gravity...that one''s got me...so i was just wondering what you experience has been! :jointsmile:

i will be following to see the results...thanks! :thumbsup:

great avatar :thumbsup:

From what I understand, under LED, gravity should work fine. It's typically HID users that have issues as the plant becomes less tolerant of heat. (This is why it is not recommended for plants that bear fruit, as it'll force fruit dropping, similar to heat issues for most other plants.)

[demoreal]

Today I top fed 4 of the plants with 2ml/(4l water) of purple max

will post some new pictures soon...

[demoreal]

Nice Air flow between flowers:
4 two liter bottles in between plants and one on floor with a bubble counter so I know when to add sugar and yeast.
bubble counter: 1bubble/sec
solution: 4 days old

[stra8outtaWeed]

they are filling in nicely....and a little Co2....nice :thumbsup:

hey you got you links fixed...right on..so it worked

[demoreal]

Thanks!!! str8outtaWeed for leading me to bigtopsfinn for the computer technical help. I would rep both of you but I need to spread some rep first. I owe you guys.

[khyberkitsune]

Looking quite nice! I've thought about CO2 supplementing in my PC box but I wasn't exactly sure with the current airflow. If I sealed the case entirely, I'd put a box of dry ice with a tiny hole in there and let that roll instead.

Gives me something to ponder for next time :)

If you do use dry ice let me know what it does to your humidity.
I have my fans on a controller that turns my fans on at 80 F then off at 73 F. I want to bump up the heat to go on at 85 and off at 78. I am not going to do this until I buy those throw away co2 testers to make sure there is enough co2 to make the extra heat beneficial.
The sugar yeast method did not mess with my humidity to bad. I wish I had a 20lb tank...

[demoreal]

purple maxx test:
used 2ml/ 4L
purple maxx again to 4 plants
this is the second watering of it

Doesn't do too much, instead it will actually dry out the air as pressure from the expanding CO2 gas pushes the regular air out of the cabinet.

[demoreal]

purple maxx test:
used 2ml/ 4L
purple maxx again to 4 plants

Did this again tonight, will wait a few days then increase dose to 3ml/4L

[demoreal]

Day 39
Could have grown one more plant in center

[demoreal]

All plants look the same, will add more purple maxx to test plants soon. At the rate of 1ml/L

[demoreal]

trichomes getting cloudy

2 plants = 1ml/L purple maxx
2 plants = 1ml/L purple maxx .25ml/L gravity
2 plants = .25ml/L gravity
2 plants = no gravity, no purple max

My purple diesel plant is not purple. My temps even get down to the 50's at night. It has purple smell, but no purple. I do not really care, just an observation. It looks and smells amazing.

[khyberkitsune]

Quite often a 'purple' strain is just crossed with the purps and doesn't actually purple. It maintains some unique characteristics like the dark dank fruity smell but just doesn't retain physical characteristics like visual purpling.

[demoreal]

Fed 4 plants 1ml/L of purple maxx and 2ml/L of sweet

I feed all the plants sweet I just gave the ones being treated with the purple maxx a little extra along with the dose of purple max.

I was going to give another dose of gravity today but ran out of PH testing solution and did not want to risk it. I will get give another dose in 2 days.

For sure. The breeder I got the clone from was only interested in the purple flavor. Unless it turns color in a week or so. I do like eye candy.

[CovertCarpenter]

... Nice compact garden, lots of light, great looking ladies :)

I also /very/ much appreciate that you're doing the nute supplement experiment there, as I have been thinking about what to augment my own nutes with. PurpleMaxx and Gravity have been on my maybe list for a while, and if you can sort of 'prove out' that they /do/ work, I'll be down buying 'em tomorry...

[shameless plug: for those in TO, or the GTA, go see Jeremy at Grown Hydro, new store at 634 Yonge--he'll treat ya right!]

Am currently using Dutch Nutrient Formula, just about to switch to the flowering set, with a teensy bit of molasses and some of DNF's SuperThrive knockoff, "HydroThrive", with pretty good results so far. I love the Co2 enrichment you're doing, and am about to start doing something similar!

Keep up the mega-good work, mon!

I was super ripped the last time I was looking at that last picture. I didn't realize you had your girls next to the fireplace...I thought it was just a random shot that made it in....And, people don't think the flowers of cannabis look wonderful? Everyone should decorate like this!:jointsmile::jointsmile::jointsmile:

Thanks for the comments! I will post more pictures soon. This grow is nearing its end.

hey them girls are lookin good how much do you think your harvest will be? great job again

[demoreal]

I am not sure. I should have grown one more plant in the middle. I also could have vegged them a little bit longer. I thought they would grow into the light but they stayed a nice size. I am growing at 100 watts of HPS per square foot.
I do not want to take any guesses but I will post what I yield.
It is a crazy grow. One big bud each plant. No popcorn buds, no lower loose buds. So whatever I yield will be good bud.
Thanks for the comment! Come back soon. :)

[oldmac]

Hello Demoreal,

Decided to take a look at what you are doing and I must say it looks very nice. Neat, clean setup and I compliment you on some great lollipoping. The pics by the fireplace are really very pretty!

To answer your question from the other thread, no this ain't SOG. If you at least doubled (or even quadrupled) the plant count and gave up some veg time you'd be closer to it. BTW the 400w for a 2x2 area is great, too many hobby growers go too little wattage. That old saw of 50w/sqft is really just a minimum, for vegging, at 100w/sqft you are in great flowering shape.

Also, good use of very old technology....yeast, sugar and water to produce CO2. I still use that sometimes, with good results.

Good growing and good luck to ya.:thumbsup:
BTW just noticed it's your 1 year anniversery at cancom, congratulations!:D

[demoreal]

I was thinking about doing a grow with 4 inch cubes all right next to each other. It would also be nice to compare to this grow. These plants vegged about a week or two. If I did 4 inch cubes I would not veg at all.
Do you think I should do that with a sativa grow? Or do most people prefer Indicas for a SOG.
If the plants I have now were any closer the fan leaves would cover the buds, but I guess if I did not veg the fan leaves and colas would be much smaller. I could fit 36 plants instead of the 8 I grew. (i should have done 9) I really want to try.
Old mac do you have any pictures of someone growing 9 plants per square foot? I have been wanting to try but I am scared it will just be too many. The most I have done is 4 plants per square foot. It would be a nice experiment too. The reason I want to use a sativa is because they tend to be more skinny without those huge fan leaves. The way I did this grow was good for this strain but would not work for a sativa very well. (lollipop style) So for this trainwreck clone I have I was thinking either a SCROG or the 4 inch rockwool SOG. What do think? This clone stretches crazy and is really skinny.

[khyberkitsune]

I've done maximum 5 plants per square foot in a hydro bucket, flat-out 12/12 all the way from the clone having rooted.

I would recommend indicas for 12/12, though if you did a longer extended staggering rotation (say every 4 weeks instead of every 2 due to the longer flowering time of sativas) then you could probably do it.

I'd really be scared to try 9 plants per square foot, even with indicas and the best hydroponics system possible. I think it would just crowd too much and be a large risk of bud mold and rot.

[demoreal]

It is my first year here. cool.

That is what I worried about. The most I have done is 4 per square foot with about a week or so of veg and they barely made it.
I have always wanted to try 4 inch cubes right next to each other yet am scared. If I find the right strain I might try it. The grow I am doing now seems perfect though. The colas are nice sized and they have just the right amount of space to breath. The most plants per square foot I have seen are 5 1/2 inch pots placed right next to each other. 9 plants a square foot seems too much. I agree. If I see a picture with good results I might try.

[demoreal]

Did some testing today.
I checked substrate pH and the top was 6.5 and the bottom 6.5
not good. I did not have my pH tester the last few days.
Another interesting observation I had was with EC.
I flushed on day 44. After flushing the substrate TDS was 127 (ECX500) and substrate pH 7.0
After feeding (RES TDS 790 and pH 5.0-5.5)
Day 44
SUBSTRATE TDS
top: 370ppm pH: 6.5
bottom: 500ppm pH: 5.5
RES AFTER FEEDING
775ppm pH: 5.5
during this week I adjust res, top off, add additives etc...
Day 52
Before feeding (with minor adjustments)
RES
880ppm pH:5.0
SUBSTRATE
top: 1000ppm pH: 6.5 for tds mixed top and bottom
bottom: 1000ppm pH: 6.5
SUBSTRATE AFTER FEEDING
top: 440ppm pH: 6.5
bottom: 940ppm pH: 5.5-6.0
RES AFTER FEEDING
TDS 880ppm pH: 5.0

I used to only use 100ppm of cal-mag. I noticed a bit of mag deficiency so I started using 250ppm. This fixed the mag deficiency but it is making my pH rise pretty quick. I am in the process of figuring out just the right amount of cal-mag to add. The way I am going about it is when I change my res I try to balance the pH of my base nutes and cal-mag to around 5.0-5.5 It has been hitting that range with around 250ppm of cal-mag at this stage. My base nutes are around 600 When I only added 100ppm of cal-mag my pH was too low. (I use a silica additive to raise my pH) Now at 250ppm my pH is fairly stable. (my plants miss there silica, its ok more ppm for other stuff)
The way I go about adding my base nutes is I check the TDS before and after i water. If there is a huge drop in TDS I bump up the ppm of the base nutes with the appropriate balance of cal-mag. I add my supplements a few days after res changes. I do this a few days later just to make sure my cal-mag and base nutes are in balance. This is how I have been going about figuring out how to feed my plants. So far this method has been working really nice. I do not know if it is the right way to go about things but my plants are really happy and almost ready for harvest. I like this method I am using because I am able to tweak a custom feeding schedule for each strain I grow. Another thing I notice is it is not far off track of the feeding charts from various companies. Right now I am at day 52 using 250ppm of cal-mag and around 600ppm of base nutes. This is all figured out just by stabilizing the base nutes uptake (by checking ppm before and after) and stabilizing my ratio of cal-mag to base nutes (by checking pH). I have no idea if this is a good way to go about things but my plants are happy.
The pH and TDS stuff I posted does not really apply to how I go about fixing my nutrients. It is just an example to keep an eye on your substrate and not just your res. Things can get messy by those roots. I notice after a flush the TDS of the substrate slowly increases each day. When it gets above 1000ppm I flush. This happens about once a week to once every two weeks. (I need to flush now)
Just thought I would post how I do my nutes. I have never read about this style anywhere. People usually follow a chart or use 1/4 strength then bump it up to 1/2 etc... My method is all about stabilizing (and of course what my plants tell me). I am not saying it works any better than any other method. It is just my style. suggestions?
my plants seem to be happiest when TDS is stable to a slight drop after waterings.
I water once a day. It might be beneficial to fit in another watering. As the plant drinks the substrate starts going a bit mad. Once a day has been nice so far. I might aim for twice a day next grow.

my starting water is around 40ppm.
Thats tap. The bay area has some good water.

2 plants : gravity .3ml/L sweet 1ml/L
2 plants : regular feed includes sweet
All plants still look the same, no negative effects, no positive effects.

will flush tomorrow and change res, substrate EC is getting high

co2
I stopped using co2 a few days ago and noticed my plants do not drink as much. The res used to loose a few gallons after a feed, now I do not notice much solution missing. The yeast/sugar method seemed to work. I did have bottles of it all over the place and my tent is small. Next grow I will get a co2 tester to see if it really helped. I really want bottled co2 but can not afford it at the moment.

The one thing missing from this post is the temperature average. From that I could tell you more about your CO2 usage and where to bump it up or cut it down. Yeast/sugar Co2 generators work but unless you're an experienced brewer you might have trouble keeping the culture operating efficiently.

my controller would turn the fans on at 85 F and off at 78 F
The bubble counter would make an average of 2 bubbles every 3 seconds. I do believe co2 was working quite nice. When I stopped using it the plants did not drink as much. Actually a very big drop in how much they drank. With co2 my res would be about half empty in 3 days, when I stopped using it, my res was about 1/4 empty if that. I had quite a bit brewing. I will buy those 20$ co2 testers next time to see how much it really did produce. From posts I have read, people say to put new sugar in every couple days. From experience I learned my bubble counter did not even start working till about day 2 and would start producing about a bubble a second. It would mellow out to about 2 bubbles every 3 sec 4 or 5 days in and then in a week about a bubble every 3 sec. I would add sugar every week and change yeast every two weeks. From my observations of the bubble counter and how much solution was missing from the res I believe It worked nice. I did not even get a bad smell, except for once when I left my grow for 10 days. When I got home my house smelt like moonshine vinegar. When I get the tester I will post results. I will not use co2 the remainder of this grow. Trichomes are getting cloudy.

All plants are beginning to turn purple. Sometime in the next week or so I will look at all the plants under a better light and determine what differences I see between the plants treated with the Humboldt nutrients.

I am at day 58. 25%clear 75% cloudy.
I will push with nutrients about a week more, maybe longer.

Thanks, I always trim the bottom branches. This is my first grow where they all actually look like lollipops. They came out crazy looking. I would like to keep them going even longer but I have to cut them down soon. I am at day 63 but these guys look like they could go to day 80 or so. They are all starting to purple. I will stop all food in a week. I will be mellowing it out for the next few days. Only molasses for a bit and then just pure water. I am harvesting day 73.
I sill do not see much amber but I am hopping for it in the next week. clear/cloudy 20%/80%
I am surprised how long it is taking. I thought they would be done by now. I just have to be patient. I also cure for 3 months...

Nice grow,wouldn't have thought CFLs worked that
well :thumbsup:,my bad.

In the first photo on day 67 post what is going on with the edges of the leaves? Do you know? I have the same thing but much earlier in the flower cycle like the first week of flower.

I sure wish I new what is the cause?

seems its always something with hydro

There is a 400 watt HPS above the cfl. hahaha I think that is why the cfl is working so nice. :)

I am not sure about the leaves. I grow in rockwool and I started watering my plant once a day. The pH of my res was low, 5.0-6.0 (I use the liquid test, orange-yellow) It did not drift much and all was well. I read the paper I have in my sig on pH management. After doing so I started testing samples straight from the rockwool and it was high. Like 6.5-7.0!!!! I came to a conclution that I should water more than once a day. Now I do it twice. I do not want to water more than that unless I change mediums. It has helped a bit at stabalizing the pH of the rockwool. It is now around 6.0-6.5, It goes up the longer I do not water it.
Every grow I have ever done my leaves start loosing it around day 60. Except a sativa (Trainwreck) the leaves did not start loosing it till around day 75. I do not know. It seems like a fight for me to harvest things later in the window. I need advice on this one too. At least advice on how to help stabalize the pH of rockwool. I gave it a pre soak but mabey it was not enough.
Even with watering twice a day with a pH low like 5.0 the rockwool stays high. I need help too.
I think it was pH related. I also did some experimenting this grow trying to get my ratio of cal-mag to bloom nutes. So that might have been off as well.
I also fed on the lower side. The highest my EC went was around 1.8, that was good though, when I went any higher the ec would rise. When I went lower it would drop. When my medium got to aound 2.0 I would flush. This was not a problem. Ph was my problem and getting the cal-mag to bloom ratio down.
Suggestions anyone?

edit: I think the pH problem was related to too much cal-mag, This was being left in the rockwool making the pH rise. I am not sure.

I just wanted to show you guys this pic.
These buds are both taken from the tops of two plants.
One was treated with gravity and the other was not.
This post is just a picture, my review will come soon, I am really busy trimming. I will post both positive and negative observations.
both buds weigh 1.5

damn does that say 7 gz and 15 for those little nugs?

[COOLWHIP]

No look again the first one is 1.50 and then 1.46 and the final 3.00

just remember I am not promoting anything. That stuff does work, and does what it says, but I still need to write a report on it. It is both positive and negative. The bottle does not lie, it does what it says but I am not sure I would just dump it in my res. I will use it again, I would also like to confirm results.

Purple maxx was hard to tell, my test is inconclusive with that one. I noticed a few things but it most certainly needs a retest to confirm. I will post those results as well.

I am out of town, I will post up in a week. This was a fun test.

I will be testing other nutrients as well, instead of my 2x2 unit I will be using two botanicare micro gardens. Two fits perfect in my tent. There is so many nutrient tests I have found on boards. They are not that great;
"I just started using (some nutrient) when I started flowering (switched the lights) and my plants started growing soooooo fast, (some nutrient) works so well!!!!!!!"
get it? (stretch)
anyone else notice tests like that?
Or the tests when there are no test plants.
"special" bloom nute additive tests are the best, when people claim buds are growing on buds. Many strains do that without any special nutes.
I don't know maybe its just me.

I will get back later with things I noticed with this test.
