What do you think?

[anon12]

Hi all,

I am currently doing my own small indoor grow and when i say small i mean only one plant. Was wandering if someone could tell me how my weed plant is doing from the pics below. Its been growing for a little over 6 weeks now and is getting bigger every day.

Btw the bottom have yellow spots which then turn yellow and shrivel up and die as you will see in the pics

[Poncho 'Milla]

I think you have a Nitrogen deficiency in your soil and that you should give it some balanced plant food. My recommendation would be a liquid feed over plant stakes so that you can flush the soil if it happens to be too much, too fast. Been I while since I used the stakes but I seem to remember them getting soft/dissolving within a few days, could be wrong though.

[anon12]

I've been using an NPK Fertilser dissolved in water.. To be specific this exact fertilizer:

Chempak - Cactus & Succulent Fertilizer
N:P:K ~ 8:34:32 with added Magnesium (Mg) and trace elements

296391

296392

296393

I purchased this fertilizer the other day and was thinking of using this stuff to see if it gets rid of my problem:

Miracle-Gro Singles All Purpose Soluble Plant Food

296394

296395

I've also got this stuff which is on the way (more plant fertilizer)

Eazifeed 250g Fast Acting Soluble ALL PURPOSE Plant Food Indoor/Outdoor

296396

[Poncho 'Milla]

Ah, I mistakenly blamed the nitrogen. That was my first guess because it most often effects the lower leaves first and always from the tips/edges in. It is more likely though that phosphorous is your issue. The fert you're using has really high P and K values. An abundance of phosphorous can hinder the uptake of zinc, potassium, and iron.

I'd recommend doing a soil flush and then going a couple of days on just water. I'm thinking that after the excess nutes have been flushed your plants will start to turn around. Wouldn't advise going back to the Chempak either. The N value in the Miracle Gro is higher than you want for a young plant, but perhaps you could dilute the solution to exchanging one excess for another? I wasn't able to find the NPK of Eazifeed.

[anon12]

Hi Poncho,

Thanks for the advice. It has now been 4 days since i last watered my plant using the Chempak fertilizer. Today i added plain water ( a bit less than about 250 ml) into the soil and also sprinkled the plant leaves with plain water with my hands and fingers until the plant leaves dropped down so they got a good drink.

My question is, does that sound like the start of a good flush (getting rid of the excess fertilizer)?

Also, some of the bigger plant leaves in the middle of the plant have developed yellow spots on them which weren't there before (but i'm hoping this primary (first) flush will help to get rid of that in the future. I will continue to only use plain water for the next 3 - 4 plant waterings.

Please let me know what you think. I have posted pics below of what my plant currently looks like a couple of minutes before i did the soil flush with the plain water as explained above.

Not too shabby, brah.
Maybe a little small and pale, but that's fixable

As a general rule, when plants gets as wide as, and taller than, their shoes.
And the bottom fans start to yellow and resorb.
It's time for bigger shoes.

Take a close look at the weep holes.
See any root tips?

Prepare the new soil with PH'ed, lightly nuted, water.
Add some of that soil to the new pot so that your gals sit just below the rim.
When the height is right, add moist soil all around.
Carefully lift it out your girl, pot and all, leaving a shaped hole.

Take a piece of thick paper, or cardboard, cut a slit to the center of it, and pull the slit around the stalk.
That will catch crumbs and keep your root ball intact when you flip it over.
Turn the pot upside down, supporting the cardboard with your hand, and rap it's rim downward against the edge of your bench.
The ball will drop out of the old pot onto your hand.
In one fluid motion, turn it upright and drop it gently into the shaped hole.

No transplant shock, they don't even blink.
You will see a burst of growth right away.
When that slows, feed it normally.

You are off to a good start.

Aloha,
Weezard

I would also add that, if possible, you should try to pick up a different reflective material. I believe Panda or mylar would be a much better alternative to aluminum foil for you. Also, what kind of bulb or bulbs are you using - spectrum and wattage? For 6 weeks along, I would think it could be a bit bushier but I could be wrong depending on strain or other factors, I am still learning, too.

Nice job keeping your plant alive this far along, you are very patient!

[anon12]

Hi d00g,

Bulb that i am currently using (19th November to 10th December):

MiniSun 23w BC B22 Energy Saving Daylight CFL Spiral Bulb

Colour Temperature: 6500K - 1000 Lumens
Incandescent Equivalent - 100 watts
Luminous Flux - 1000

Bulb that i used from: 19th November to 28th November:

Cool White 35w Energy Saving Spiral Light Bulb

35w spiral very bright 175w equivalent
Cool White 4100k Colour temperature

Bulb that i used from: 21st October - November 19th:

MiniSun 65w BC B22 Energy Saving Daylight CFL Spiral Bulb

Colour Temperature: 6500K
Equivalent to a 325w standard bulb

I have looked into reflective materials and i will decide on what to do.

The strain of the weed is: Seedsman White Widow (Feminised)

Growing weed is a tricky process but you need to do it right to get the right results also i'm learning something new every day.

Here are some pics taken today of how my plant is looking:

Wasup Weezard,

Thanks for the input.

I have ordered a new grow box which should arrive withinin the next 1-3 days. I will also transplant the plant when the box arrives as my current grow box is falling apart and too small for the current plant which has out grown it as i cannot hang the light bulb any higher which means it is too close to my weed plant.

My weed plant has needed to be re-potted since about the 1st of December and it is now the 10th and the plant is still in the same plant pot it has been growing in since i started the grow. I am worried that the roots have no room to grow and how this will effect my plant in the long run.

I am buying a 2 litre, 3 litre, 5 litre, 10 litre, 15 litre and 20 litre plant pot with drainage holes in order to see which one will be best for re - potting my plant. However, i was was wandering if you know weather i could just re-pot my plant in a plant pot big enough so it can grow to full size and maturity without me having to change the pot again in the future. What size pot should i use for this in litres?

Is putting a small weed plant in a big plant pot bad for it?

Thanks

[Weezard]

"Is putting a small weed plant in a big plant pot bad for it?"

Yes it is.
That's why we go to all the trouble.
It's also why we do the minimum impact transplant.

If the root ball is too small for the pot the soil can get waterlogged and go stagnant.
Then the benefits of a large pot become detriments.
They stunt, then die.

Not saying it can't be done, just that it is extremely difficult to do properly.
I'm way too lazy to do it over, so I up-pot in 4 stages and even then water very carefully.
1 pint, - 1 gallon - 3 gallons, - 5 gallons.

This summer, I'm trying for trees and have some 10 and 15 gallon bags waiting for the eager Sheila's.

Aloha,
Weezard

[anon12]

Judging by the above pics which were posted today: Dec-10-2013, 14:18, what size plant pot would be good for the next period of growth.

Regards,

anon12

[Chromophore]

Ditto everything Weezard said and I will add that keeping the pot/rootball size ratio fairly small forces the plant to use the resources in the soil. In extremely soft soils (like potting soils) the rootlets can grow very fast and when they stretch their absorption efficiency declines and they become weaker. Confining them forces the roots to mature and use the available nutrients completely. Once the root density becomes high, putting in a fresh zone of soil allows the plant to grow rapidly. After you have done this several times, you will have a plant with a root system that is very mature and dense. Just in time for flowering.:smokin:

The next larger size of course. :)

You want a couple more inches for depth and at least an inch more in diameter.

If you have height restrictions, keep the pots squat, and increase the diameter.
Cramping the tap root inhibits vertical growth.
Wider pots, grow wider plants, and put a lot more feeder roots at the drip line.

I strongly advise you to take notes throughout the grow.
Just the date, and what you did, to start.
Take pictures and attach them to your notes.
Or, the notes to the pictures, whatever works for ya.
Next time, enter the date and your observations, then what you did next.

Hold a little root ball postmortem after harvest, and record what you see.
Just quarter it with a long, sharp, knife and take some pictures.
Then you can match your observations to your past actions, yah?

We all say; "I'll remember that!"
Um, not if you have a successful grow you won't
The reason I started posting on Cdot was to have a semi-coherent record for my own use.
Found priceless mentoring from actual master growers.
Then discovered the archives! (1st link in my sig.)
Nevah have to buy another grow-book.
The master growers have their notes posted in the archives already.
Free for the reading!

Your own notes will be the best possible tutorial for growing that particular "strain" again.
(Did I mention that different "strains" have different preferences?) :D
But to answer any cannabis question you can imagine, just click on, "everyt'ing".

Enough pontificating from me though.
Truth be told, I'm a rank amateur with 2, black, thumbs.

'I strongly advise you to take notes throughout the grow.'

I've been doing that since the beginning of the grow with pictures as well. Its all very extensive.

[anon12]

I'm getting a bigger box (about 5ft tall) so i will have plenty of room to grow this little gem. I don't want to restrict the plant as adding a shallower plant pot with a wider diameter can only go so far in a small box. I think the solution is simply to get a bigger box which is what i have done.

Hopefully if it arrives tomorrow then i can re-pot my plant and also do some other changes such as change the light bulb to a bigger one with a higher wattage (325 watts with a Colour Temperature of 6500K) until its time for flowering, then i will consider switching the bulb to a warm white or soft white bulb with a colour temperature of 2700k (because thats what i reas is best for flowering) not sure what the best wattage for flowering a single plant with a single bulb is though.

Need to think about a reflective material for inside of the box (all i have is tin foil so i may have to spend some more cash on a better alternative)

Got a Ph tester in the mail also seeing as my plants lower leaves are turning yellow and dying. (Im guessing its the nutrient issue mentioned at the top of this thread)

Also, how far saway should the light bulb be from the plant? I'm using a:

MiniSun 65w BC B22 Energy Saving Daylight CFL Spiral Bulb

Colour Temperature: 6500K
Equivalent to a 325w standard bulb

It was approx 30cm away for the first day in my new grow box but then i read online that CFL's need to be about 2-4 inches away from the plant which i thought was very close, but apprently thats what everyone is saying. I guess its to do with the heat emitted from the CFL bulb. So now the CFL bulb is 3 inches away from my plant with a little usb fan blowing at the plant about 5 hours a day.

[Weezard]

Got a head's up for you.

Best to empty the saucer right away.
Standing water keeps the soil too wet and the roots run out of oxygen.

She's looking good.

You can figure the distance to that CFL with a thermometer.
No got?
Use the back of your hand.
Too hot for you?
Not good for her.

Carry on, carrying on.

Hey anon, great to see you adapting and being proactive! You have a GREAT resource following you in the Weeze! I was having an issue with drainage water pooling in the tub that my soiled plant pots were resting in. I flipped over an entire Rapid Rooter plug-holder and cut it up to adequately fit my 3 large pots. The pots stay on top and drip the water freely through the homemade drip filter, and my plants sit, happily about 3 inches off the basin. Then, I drain and disinfect the basin every 2-3 days to avoid water pools which attract insects and algae/various bacteria.

My plan is to buy individual catch-basins (Weezard calls them saucers - I'll go with his terminology!) for each one of my 3 plants. This will help in ease of draining excess water after waterings, measuring runoff pH, and they'll also make it easier to spin the ladies to spread the light until they're big enough to tie them down. I will put the upside-down RR holders in them, too.

[anon12]

Just purchased a:

3in1 Soil Moisture/Humidity Light PH Tester Meter for Plant Flowers Fruits added to soil

Which looks like this:

My question is: Do i leave the soil probe in the soil 24/7 and just just flip the switch when i want my 3 readings, or do i take it out every single day and clean it then re insert it the next day when i want another reading? I'm just worried about damaging the roots if you see what i mean?

Thanks,

[anon12]

Started the flower cycle a couple days ago and i am wondering what a good amount of lights i should use. I was using a cool white 65w(equivalent to 325 standard watt bulb) with 6500k cfl bulb.

I have switched to a 35w (equivalent to 175w standard watt bulb) with 4100k cfl bulb.

I have three different cfl light bulbs to my disposal as seen further above in this thread. However, i was wandering what bulb i should be using for the flowering stage and how many bulbs i should be using.

Thanks

[d00g]

Hey anon -

For flowering stage you will want to use Warm White bulbs in the range of 2200K-3200K. You need to switch from the 4100K as soon as possible. The more light you can get on your plant, the better. Reflectors also direct the light to increase the amount of light that is reaching the plant.

Looking forward to seeing some new pictures.

Hey again, anon -

Thanks for the pics, I love to see that clean green! Looking like a very healthy plant, just make sure to read about specific growing spectrums that plants use for their different stages so you are fully aware of the light needs of your lady. Keep us updated as you are switching to Flowering stage! I am about to switch my own 1st grow to Flowering stage, so I will be sure to follow you.

[anon12]

Thanks man I've put alot of sweat and toil into this one plant just to get that nice strong potent bud at the end of it all! Fingers crossed it all works as this is my first serious grow aswell. Tried it before like 4 years ago with 4 plants but was no where near as serious as i am now so it didn't work out.

Anyway, I have some updates on the fertilizer AND Light Bulb issue:

Info on the Eazifeed Fert:

Eazifeed Soluble Plant Food All Purpose for Indoor and Outdoor use.250g, and mkes up to 100 watering cans.

NPK Fertiliser:
15-5-30 plus trace elements
Total Nitrogen (N): 15%
Ammonioacal Nitrogen: 6%
Ureic Nitrogen: 9%
Phosphorus pentoxide (P2O5): 5% (2.2%P)
Solouble in nuetral ammonium
Citrate & Water: 5%
Pottasium oxide (K2O): 30% (24.9%K)
Solouble in water: 30%


Added less than a quarter measuring spoon Eazifeed Solouble Plant Food ALl Purpose ( ) into slightly less than 250CL Bathroom tap water
Put about 210 CL Into soil until seeped out of bottom into drainage plate
Excess water still in drainage plate (need to drain but it has valuable fert in it! Might drain it what you think?

Turned two of the three light bulbs off leaving the 35W (175 Watt Equivalent) 4100K Cool WHite Bulb on in the middle directly above The plant on by itself.

Just to mention i have invested quite alot of money already into this one plant and now i'm having to make the decision on to spend even more to buy the correct bulbs as the ones i am using for the flowering stage which i started on December 16th in 48 Hours of total darkness then On December 19th I officialy began the 12/12 light cycle but with the wrong light bulbs and i am worreid how this will effect the buds?

I really do not wish to spend any more than i absolutely have to as i am only growing one plant. The bulbs are around £5-8 EACH and i will probably need at least three to maximize the light in the grow tent as i have no reflective material either just the white canvas that surrounds the grow box as the reflective stuff is about £3.00 a metre.

[anon12]

Update:

Just decided to spend more friggin money becuase i had to and purchased:

Mini 25w Energy Saving Spiral Light Bulb, 125w Equivalent, Bayonet Cap B22, New Advanced T2 Technology x 3

Luminous Flux 1500
Wattage 25 watts
Incandescent Equivalent 125 watts
Bulb Features Flicker free with fast start up time
Colour Temperature: 2700 Kelvin
Colour: warm white

AND

DIAMOND MYLAR REFLECTIVE SHEETING 5m x 1.25m SILVER FOIL LIGHT PROOF

ADVANTAGES:

Diamond diffused pattern to spread light more evenly.

Produced to help eliminate grow room hot spots.

100% lightite (a true BLACK OUT, test it yourself!).

PET coated to protect against corrosion and wear.

With Membrane Memory to dramatically reduce creasing effect.

FOOD SAFE. PLANT SAFE PRODUCT.
NON GASSING GUARANTEED.

[d00g]

Nice job getting the mylar, it will make a huge difference in the amount of light that is reaching your plant. Hopefully it didn't cost you much. And also nice job getting the 2700K bulb. Keep in mind that 2700K CFL bulbs seem to be the easiest to find bulbs at home improvement stores like Home Depot or Lowe's. Those stores have the largest selection of light bulbs (at least in my area) - most of them useless to us - but I generally see CFL bulbs in the 2000K range for very cheap - like $3-4 for the more luminous of those bulbs. So, hopefully that didn't cost you very much either.

Looking forward to seeing more pics and updates! I know it's not fun spending the money but isn't it fun upgrading and evolving with your grow? That's what I have enjoyed the most.

[anon12]

Thanks. Just hope its all enough materials and bulbs to do the job right so i get a strong potent THC rich crop! I have enjoyed learning about this beautiful, magical & special plant. I'm glad about the strain i have chosen since it is one of the best and there are so many damn strains to choose from.

Yeh, its true i suppose it is fun & exciting upgrading and improving my grow. I just hope i haven't hindered the final results by not getting the correct equipment from the start but time will tell i guess.

This whole grow was meant to be a small one which has turned out to be rather large & expensive but is the only way to do it properly imo.

I can't wait to see what the buds look like in a couple weeks time. More pics to come for sure!

[d00g]

I feel the same way about my first grow - it has turned out to be more expensive than I planned but feels good because it seems to be the proper way to get the results we want. I believe it will be worth it in the end and I hope you feel the same way about yours. My plants are starting to get a bit stinky when I stick my nose into them and it makes me very happy.

[anon12]

Same here, there changing colour and everything! Added the Mylar today. Just waiting on several light bulbs to come in the post to assit in the flowering stage and my grow setup will be almost complete. Might buy some slow release plant food aswell to boost growth. I can't wait to see how my plant buds. It's meant to be white widow so im expecting lots of white crystals to emerge.

You posted up any pics of yours? What strain isit btw?

[d00g]

Yup my grow log is titled "First Grow - Pro Grow LED Cabinet Grow" in the Grow Log section of this forum. I try to use it to track my own progress and get tips from people that have done many grows compared to my 1. I am growing THC Bomb and my plants are just over a month old and about half as tall as yours but bushy as hell. I am going to start 12/12 with my LED/CFL setup in the next few days.

[Hotshot123]

Just a little tip about your CFL's, always turn your bubs more side ways, so the plant will asorbe more light from the top, and I see you have some on the side of the plants, that is good. There is a lot more light comming from the curls then the end of the lights. Good luck, and happy growing.

[tlranger]

First grows always seem expensive, but so much is reusable next time around. Well thinking on it, they all seem expensive till the bud is being smoked, then it's "I grew this, isn't it great". Hard to stop with just one. You have a career a "head" of you.

Nice pics man. You got everything you need to grow some good weed. Your grow is extensive. Liking the use of the cabinet as a grow box and extractor fans. Yeah mine isn't as bushy as yours but mine is much taller. The strain i chose is mostly a sativa so therefore i can expect my plant to grow tall and long with less leave foliage whereas i'm guessing by the look of yours its mostly an indica which tends to be shorter but much more bushy.

However, i chose a sativa genus over an indica seeing as the sativa's tend to have a higher ratio of THC VS CBD (THC/CBD) as apposed to indicas where their ratio is the other way around: CMD/THC. THC is what gets your high whic is what you want where as the CBD chemicals are better for medicinal purposes like relieving pain etc...

Good luck with the flowering stage btw!

anon you need to think of light intensity in terms of density. In other words, lumens/ft2 . Lumens by themselves don't mean anything if you don't know how much physical space they are spread over. Figure out the square footage of your area under the light, then you can determine light density. My 2cents is minimum of 2000 lumens/ft2, optimal 5000-7000 lumens/ft2.

[anon12]

I am using 3 CFL bulbs at 1500 lumens EACH BUT I will be changing them to bulbs which have 2275 Lumens EACH.

The results for the light intensity of my grow box:

Square Footage Under Light Source = 4 Square Feet
Formula: lumens/ft2

1500/4 = 375 x 3 = 1125 Lumens
2275/4 = 568.75 x 3 = 1706.25 Lumens

minimum of 2000 lumens/ft2, optimal 5000-7000 lumens/ft2.

So according to your formula i need 20,000 Lumens? Thats hell of a lot...

[Chromophore]

5000 lumens/ft2 is the figure I see all the time as the minimum for optimal flowering. The data on lighting is bewildering and everyone seems to have their own ideas. I'm just regurgitating the common info that I've come across. Also I don't use cfl and things may be different when using that kind of light. The other variable here is distance from the light source, closer=more lumens. When people rate a bulb by lumens I believe they are measuring at 1 ft. distance. Hopefully someone with more experience with this (esp. cfl) will answer. But you should google it. There is a ton of info about this out there. Also the Grow FAQ on this site discusses this.

[Chromophore]

Also anon there are other variables involved, so I think these figures are guidelines rather than firm rules. I have my plants spread out to about 25-30 ft2 with a total of 116,000 lumens that's about 4,000 lumens/ft2 which would seem too low, but I use two lights with overlapping light cones as well as light spreaders. My plants seem vibrant and healthy.

True dat!
However, those figures are for a more of a point source light like HPS and MH.

The advantage of CFLs is the fact that, like LED arrays, they are not point source lights.
We can have the plants much closer to the bulb and we catch a break on the inverse square law.
This time it works in our favor,
As you get closer to the bulb, lumens per square foot soars.

Go with the stronger light and select for color temperature.
I'd recommend that you use "warm" white for flowering.

Mo' red gives mo' betta buddage.

Carry on,

Wasup Peeps:

Have some exciting news! Its has been 12 weeks and 1 day from the start of planting my seed until now AND 3 weeks 5 days from 12/12 cycle and my plant has officially begun the process of flower/bud growth. Its amazing and beautiful!

Here are some pics (let me know what you think please:

I purchased this plant food as early on while growing my plant one of the bulbs fell down onto the main (centre) leave area of the plant and caused quite bad burning. I cut the dead leaves off and sprayed some of this magical stuff onto my plant in order to rejuvinate it and bring it back to life so to speak. It did wonders. That was two weeks ago and im thinking of using it again today. The aim is to make my buds as healthy, big and potent as possible. This stuff also is meant to boost flower groth aka flower bloom.

I might be jumping in with a totally wrong opinion- but I would not…

Think about a baby, when it cries it isn't alway hungry, sometimes it's cold, sometimes it's sleepy and sometimes it just wants attention, but if momma just keeps putting that bottle in the mouth it makes for an unhealthy baby….

Good soil will have plenty of nutrients for a spell, usually through veg - then plants need food that promotes healthy soil, cuz that is where the nutrients are, alot of these nutrients are because ppl aren't always using soil….

Me personallly - I really watch how much they get fed…not only can you kill em with kindness, it tastes like shit! ;)

Looking forward to reading others opinions here cuz I am no expert!

[Chromophore]

I am not a fan of foliar feeding, because a.) that's not how plants typically absorb these types of nutrients (assuming they are absorbed at all), and b.) I don't want anything on the surface of my buds that the plant didn't put there. But I know many experienced growers do this and claim good results, so it's just my personal preference. I will say this however, humic acids are produced in the soil via organic degradation, and are beneficial because they have unique chemical properties that allow them to form bonds with minerals such as Mg, Ca, and Fe. They form complexes with these mineral ions called chelates, and these complexes are what allows proper and efficient absorption into the roots. Humic and fulvic acids are definitely good amendments to growing any plant, but I think you're better off either using soil rich in these compounds, or amending it with soil-based nutes like Budswel or Big Bloom, which are loaded with them. Just my 2 cents.

Starting to see very tiny roots come out of holes from bottom of plant pot but only a few millimeters. Do i need to re pot my plant (this will be the third pot and second time i will be repotting my plant. Its big now and flowering so i am concerned with causing damage & distress. But if it is needed than i have bigger pots and soil at the ready. What do you all think?

[Weezard]

Sure!

Sink the old pot into the new one and fill in around it with moist, not wet, soil.
It's best if the soil is already ferted for bloom of course, but not too much at first.
You want the roots to go hunting, and multiply, then feed.

Gently lift the old pot out, invert it, tap it on the edge of something to jar the root-ball loose, and catch it.
Might need some help with biguns.

Set the shaped rootball gently in the hole you made, and she won't notice that she's been transplanted until she feels the extra toe-room.

From watching my DWC grows I found that Cannabis can, and does, grow lots of roots in the first 6 weeks of flower.

Aloha,

If you could take a trip to your local hydro store I'll bet they have some free samples of Mycorrhizae products they can give you to sprinkle on the soil that will be touching the roots. I've been told many times about the benefits for the roots. I'll bet you have a big root mass wrapped around the inside of that pot!

[anon12]

Think what I'm going to do is leave it until the soil dries out then re pot the plant as i heard it is easier to free the soil from the pot when the soil is dry. Then hopefully it will release itself in one pot shaped soil clump and also the dry soil will more easily release itself from the pot since more moist or wet soil tends to stick to the sides and bottom of the pot which is a bad thing, could break the roots that way.

I'm going to just leave my plant for maybe 5-7 days without any water, just turning the fan and light on & off for the 12/12 cycle then after some time has passed and the soil is good and dry i will re pot it.

This last (third) pot should be big enough (Size 25cm (depth) by 26.5cm Diameter by 20.5cm (Bottom of pot) ) so i shouldn't have to re pot the plant again.

Thinking about it i have a horrible feeling this third pot still wont be big enough for the entire grow however it is the next size up as any bigger pot will drown the roots as mentioned earlier in this thread.

Any Maths whizzes out there know how many liters a pot with the following dimensions is:

Size 25cm (depth) by 26.5cm Diameter by 20.5cm (Bottom of pots diameter)

[anon12]

Also, i only want my plant to grow maximum 4 - 4.5 feet in height since my grow box is only 5 feet 3 inches tall. This is an indoor grow but i do want as much bud as possible since i only have one plant.

Update on my White Widow Single Plant Grow:

14 weeks 2 days since planting seed into plant pot & 5 weeks 6 days since i began the 12/12 flower cycle (Comments welcome:)
