Looking awesome man.. very jealous!!! keep up the good work!
Thanks man. I think I'm definitely going to do an "Everything You Wanted To Know About PC Growing" thread after this--been through a lot of trial and error and I want to share what I've learned.

Btw, how's your CFL/LED combo working out so far?

Eh 2 plants are half the size and doing well
the older one has drooping leaves and yellowing but soon as i watered it it sprouted up again.. ??

Confusing haha i think im gonna grab some better nutes.. their under 36 hours of darkness now so im gonna flower these 3 and wait for sex and then start autos next :)

Yeah man, it's just tricky in a soil system to use chemical (non-organic) nutes. You risk salt buildup, pH fluctuation, deficiencies, nute burn, etc. The thing about good organic nutes is that it's much harder to burn your plants, you get better types (yes, there are different types) of macro nutrients (N-P-K), and you often get the right amount of micronutrients and if you get enzymes and beneficial bacteria--it's only gonna help all your causes.

Adding a good micronutrient/enzyme blend (like FF Big Bloom) to a good macronutrient blend will really help your plants take off--I saw immediate increases in growth rate.

So, I re-analyzed my nutes and found out I was greatly depriving my White Dwarf in flowering of Phosphorus! The reddish stems confirmed this. So, as I wait for my Tiger Bloom to arrive in the mail, I ran out to Wal Mart and picked up some organic bone meal as a phosphorus supplement. I reformulated my bloom mix of nutes in the meantime and crunched some numbers to figure out my total N-P-K for my bloom and veg mixes. Put your math cap on because I sure did. Here's a rundown of my nute mix with a key and lots 'o numbers. All advice welcome.
----------------------------------------------------------------
KEY
Organic Bone Meal (unsteamed) (6-9-0)
Organic Blood Meal (12-0-0)
Unsulphured Blackstrap Molasses (1-0-5)
Fox Farm Big Bloom (.01-.3-.7)
Fox Farm Organic Vegetable & Tomato Dry Mix (7-4-5)
1 US teaspoon (tsp.) = 4.92892159 ml
1 US tablespoon (Tbsp.) = 14.7867648 ml
L = liter
(N-P-K) = Nitrogen-Phosphorus-Potassium (as % of volume)
----------------------------------------------------------------
BLOOM MIX (added to 1 L of distilled water)
1/2 tsp. Organic Bone Meal
1 Tbsp. Fox Farm Big Bloom
1/4 tsp. Unsulphured Blackstrap Molasses
total ml of nutrients = 1*tsp + 1*Tbs = 19.7156864
Final N-P-K analysis (.82-1.35-.84) as % of volume of concentrated fertilizer mix (before added to water)
----------------------------------------------------------------
VEG MIX (added to 1 L of distilled water)
1/4 tsp. Organic Blood Meal
1 Tbsp. Fox Farm Big Bloom
1 tsp. Fox Farm Organic Vegetable & Tomato Dry Mix
1/4 tsp. Unsulphured Blackstrap Molasses
total ml of nutrients = 1.5*tsp + 1*Tbs = 22.1801472
Final N-P-K analysis (2.28-1.09-.1.86) as % of volume of concentrated fertilizer mix (before added to water)
----------------------------------------------------------------

The bone meal was much needed and got my percentages more in line with acceptable Phosphorus levels.

Will post more pics in the future and updates on improvement.

Happy growing,

Porn in progress as requested for the White Dwarf.

Note the 2 colas coming through the screen--both from the White Dwarf. Have just kept vegging and topping the Amnesia Lemon--will probably turn the whole box over to 12/12 in 2-3 weeks--looking at 4 main colas so far. Enjoy!

Goooo buddy go!! looking good man! im jealous!!
Thanks man. I'm having a lot of fun doing it.

So, I can't seem to quell my insatiable thirst for tweaking and refining my grow.
-I had CFLs. That wasn't enough.
-I added mylar. That wasn't enough.
-I added SCROG'ed. That wasn't enough.
-I added LED. That wasn't enough.
-I made it completely stealth with still adequate cooling. That wasn't enough.
-I added HPS. That wasn't enough.
-I brought my temps down from 105F to 86F in one afternoon without sacrificing light. That wasn't enough.
-I bought more and more premium, organic nutes, dialed them in, with great results. That wasn't enough.
-I added CO2 (much worth it!). That wasn't enough.

-I added a light mover. That didn't work. So I took it out. lol.

What improvements are left for a PC grow without adding heat or fucking something else up? The answer: UVB.

Since I am only running a .83 square foot grow, I wanted to add UVB but didn't want to significantly raise heat, not have to add another timer (for room's sake) to only run a UVB flouro for a few hours, and not ruin my plants with too much UVB. Plus, the top of my flowering White Dwarf is only probably 8" from the top of the case. So, I bought a 5.0 26w Zoo Med Reptisun (instead of the 10.0) that I figure I can run on the 18/6 and 12/12 schedule without adding too much UVB. Got the light for $17 shipped on eBay (and the seller is in my state! = quick shipping). Pics to follow

----------------------------------------------------------------------

Now for usual updates. Made a few changes (duh, haha).

I removed the 13w LED as the Amnesia Lemon now has 4 main colas (thanks to all you threaders/posters about topping!) and can get the benefit of the 50w LED, the 35w HPS, and the 42w CFL. I replaced the 13w LED with a 20w warm CFL at the top of the case (temps are around 87F right near the bulbs--probably 80F mid-plant--with the CO2 supplementation they should be fine).

When I checked my plants this morning they were all droopy and sad! I said to myself, in a Sherlock Holmesian tone "what could it be, Watson?" Lo and behold, the soil was far too tried out as I hadn't watered in 6 days (it seemed semi-damp yesterday and the day before!). I watered and added a bit more bone meal and within hours all the leaves perked right back up as if they didn't miss a beat.

One last thing. I know this is a touchy issue. Some people are avid trimmers and some avoid trimming like the plague. Some just trim a little bit. There's the various arguments for maximum photothensis w/ all the leaves = maximum bud and the contrarians yell allow more light to get to the lower budsites, man!. Well, I heeded the advice of both and only trimmed a few leaves as necessary and as per these rules:

1. If a leaf was all yellow and dead and blocking a healthy leaf or bud site (especially if the leaf is close to light)--it got snipped.

2. If a leaf was kinda sickly, right in the light, and shielding a whole main or somewhat-main cola--it got snipped.

3. If a bottom, root-feeding leaf was sickly or dead and was blocking a productive root-feeding leaf--it got snipped.

4. The rest of the potentially-problem-causing leaves were tucked away SCROG fashion for ultimate bud-development and bushiness (my plant's canopy is probably as wide and even as it is tall).

(Relax guys, I snipped less than 1% of the total leaves and most of those leaves were all crinkly and nitrogen-sucked)

Will post pics as needed in the future (especially pending the results of the UVB supplement and the corresponding improvements--if any).

Sorry if this post is too long for too-stoned-to-read RIU-ers.

Best and thanks for everyone's help in this thread and others,

Dude, Just read this entire thread,

at the beginning i was thinking, no way is all that light not gonna make your pc an untouchable ganj cooking furnace, but seems like youve got it under control mate, really enjoyed reading and have subscribed so i can follow it to fruition!

I would wish you luck, but it looks like you grabbed luck by the horns and shoved your fist firmly down its throat!

Well done man.... peace!

With the exception of the final product, it's comments like yours that make it all worthwhile. Appreciate it man!

UPDATE: Just got back from a weekend trip and just caught my plants before the timer shut them off for the night. Yield is bulking up. Tiger Bloom seems to be of real help--I know some people knock it for a slight tendency to burn--but I haven't found it that yet--running it at 1/2 strength--that's 1/4 tsp. per quart lol! but it seems to be potent so I'm not going to doubt anything. Plus I'm using molasses and Big Bloom (at full strength)--I don't want nute burn so I'm not gonna take any risks.

The UVB lamp should be coming early this week so I'll be taking out the 42w warm CFL (it's starting to burn the top of the main cola just a tad), and replace it w/ a 20w warm CFL and the 26w 5.0 UVB CFL (again 5.0 instead of 10.0 to avoid getting a second timer and due to proximity issues)--it'll probably be less than 7" from the top of the White Dwarf.

I'll post pics soon! Leaves are getting visibly frosty from even a distance. Don't wanna take up much more of your guys' time w/out any pics or major info. I'm gonna go post on other dank growers' threads.

best,

secretforestgarden:peace:

dude you are officailly my hero, u have given me so many ideas and i too have the urge to keep building up my pc case and remodeling it to make it better. mine isnt near as bold as urs i only have 3 cfls, 2 daylight and one warm just to balance out the spec, it stays around 80 in there all the time. im broke tho so i cant do all the nutes and stuff u do lol. and i know its bad but i had to use miraclegro, i cant rememebr the type but i think tht it will turn out decent for a first grow. tell me what u think the link is in my sig. u are amazingly skilled and very adaptable(i cant think of a better word) i still cant believe tht you fit all tht into ur box.

Thanks man! There's a lot going on in my box but it doesn't matter at all unless the bud is potent and there's plenty of it:weed:

Side of the White Dwarf's main cola:


An undercanopy bud on the White Dwarf--lil' popcorn fella haha:


Top half of the main cola of the White Dwarf:


Top view of the White Dwarf:


Amnesia Lemon Topped Twice (4 main colas)--still vegging--will flower in next 1-2 weeks:


35w HPS, 20w warm CFL, and 26w cool UVB--note the Nexus fan right on the HPS for cooling:


What do you guys think? Just a few pistils here and there taking on some minor color changes so harvest won't be for awhile--I think the LED is extending the flowering cycle which is fine because I can be patient. Any experienced growers with yield estimates for the White Dwarf? I'm hoping and praying for a zip but if that's wishful thinking then give it to me straight.

The UVB has only been in there 2 days but I'm hoping it lives up to reputation: no yield changes but potency increases. Sound right?

growing is fun!

ya dude thats wishful thinking. the picture in my avatar was a WW i grew under a 70watt HPS and it was 2 feet tall from the soil,was about as big around as a Red Bull can and it only got me a half ounce dried, manicured bud. Looking good though, nice ingenuity on display, I'm sure you will continue to put it to good use, hopefully you can upsize in the future.
