2.4k Hindu skunk sealed room

First let me say this is my first attempt to grow. I did quite a bit of research before starting. My area is 7x8 flower room with 2 growzillas on a light mover which only moves about 20 inches. Inside each growzilla is 2 600w hps.

I have a sealed room, sheet rocked covered with panda poly. Cap gen2 and a fuzzy logic, my room is pretty sealed, I used to try and match the ppm of nutes to ppm of co2, but recently changed it to 1500 ppm co2. It has been running a month now and still have plenty of propane in the tank. It’s only on for 13 hrs a day though. I have a 375cfm fan sucking air from underneath the house through the lights out into the attic. A dehumidifier set at 55% and ac/heater set at 71. I run the lights at night when flowering which has only been 6 days now. I just noticed that daytime temps drop pretty low so I will turn my heat on to keep a pretty constant temp of around 71-75.

I have a small concern, when the co2 gen kicks on; it instantly brings the temp to 77-81, I don’t think that is to big of deal, but have no choice or solution how to fix this. I hand water or with a sump pump and water wand. I wish I had made room a lil bigger it’s a pain to get in there and water plants.
I would like to shoot for the SOG single cola plants. I have searched multiple sites on how to trim or prune to achieve this any pointers?

From what I read the ideal Ph for coco is 5.8, that’s what I started with and noticed quite abit of yellowing so increased it to 6.2 and that has helped. My mixture is 50 Coco (bio coco) 25% light warrior and 25% pert. I’m using Biobizz organic nutes, R/o water with (Cal mag plus up to 250 ppm) This is the feeding chart I just started using it seems a lil hot but plants have took it for 2 feedings now. http://www.progressive-growth.com/hydroponic_recipe-bio_bizz.php

Tonight I just watered with water w/cal mag ph’d to 6.2. I normally water every 3rd day or whenever they need it or the pot gets light. Check out my root ball after only 2 weeks (which was 2 weeks ago), I was impressed, I just wished the top looked as good. I have had plenty of problems during this short month, and am happy that they are still alive. I would appreciate any pointers or tips. The last 2 pictures were from tonight. Thanks in advance

Hey! Those root balls are looking very impressive. I haven't had a root ball that looked that serious yet. Good luck with the rest of your first run. If your solution seems too strong, but you want to use the same ratios as a given recipe, you can mix your rez and then top with water until you get the desired EC.

the tech support guy at general hydroponics recomends mixing half hydroton n half coco for the drip / ebbflow systems

Go look at size does matter thread in indoor soil starting page 3 on trimming techniques for single cola SOG action at it`s finest........

Jrosek has been working on this for awhile so now you can see howta do it and do it well.....

Take care and good luck......Peace....DHF........ :joint: ........

Some new pictures. I only have 2 of 4 bulbs on during first 2 weeks of flower, to try and reduce stretch, does this make since or am I missing the boat here. So a total of 1200w right now 2-600s = in a 7x8 =3392 lumen's per square foot. What are your thoughts. I would love to turn the other 2 bulbs on but am worried about the stretch due to height restrictions 11-29 will be 1 full week of flower. . I'm also considering changing to canna coco line of nutes, unless I stick with the saying if it aint broke don't fix it. Mainly due to all the reading I have done says people run into problems around 3-4 weeks of flowering when not using coco specific nutes. What are your thoughts. Thanks in advance.

Less light = More Stretch ^^

If you don't want the plants to stretch I would advise kicking on all 4 bulbs.


Watch the temps though, if you are already noticing spikes when the burner turns on, they will probably be a bit higher with all four lights on. 81 is actually a pretty solid temp for a sealed C02 enriched room, although you should check the canopy temperature directly below the bulb. If the ambient is 81, chances are the canopy is a lot higher.

Also, depending on where you live, it is probably winter time, so think about your minor heat problems once summer starts... and work on solution before the minor problems become major ^^


Personally, I like the winter when the lights off temps drop a bit lower, its a good time to pull out those purple strains they will get really dark. Just make sure they aren't getting too low.


All in all, looks like a very nice set up for a 1st timer. I to use a sealed room, but in 100% CoCo, makes it easy not having to mix anything and works well.

Some updated pictures Day 28 of flower, I made a mistake in my other post R/o and ph as far as days in flower. I can't count. I think their ok could be better, but for a first timer learning as I go. Any pointers would be greatly appreciated. Thanks

Day 32 of flower, whatcha think, I just did my final flush last night, until the finishing stage last week, I'm quite pleased for my first go, just hope I can last another few weeks. I have bad yellowing, iron, mag, and ca def, I've been using r/o water with cal mag up to 250ppm, I think I should bump it up another 50 or so, any thoughts.

I'd give them more food right away or else your yield will suffer.

Just be careful and up the dose in small amounts.

Wow nuggie your stuff looks very good....especially since the first little whipper you showed me. Looks like you have many fine minds over here to assist.....which is good because I don't know ANYTHING about C02 either. 2400 watts sounds GREAT!!

Dude if you are trying to use all organic nutes, u need to make sure you have lots of beneficial microbes. Your plants are definately not getting enough nutrients. That could be some sort of pH lockout (but you are checking that), maybe you are overfeeding or didn't flush the coco well enough (but that would cause burn which you don't appear to have), you could be underfeeding (possible) or your nutes are not being converted to a usable form. You should be innoculating with a fungi, a bacterial innoculant (just not until they are established), and some sort of hum tea type brewed protazoa. If you are using coco it will be a great media to grow the beni's but u need to put them in there. Organic nutes need benificial microbes to convert them into usable salts. That is why most hydroponic mediums don't do so well with all organic nutes. But, coco is a great substrate to grow the little buggers if you make it so.

That being said, IMHO u are making a mistake by adding difficulty to your grow by trying to use all organic nutes in a hydroponic medium on ur first run. Without previous knowledge or ur strain. Organic is great but it is more difficult in coco than chem's for sure. And, you are losing any benifits from going organic by causing such severe deficiencies.

My friends have great success with House and Garden on coco top feeding once a day. H&G is made for RO water which you are using so you don't have to worry about Calcium deficiencies which can pop up with nutes (canna) that are intended for tap water.

Sorry few more things.

Don't get me wrong, canna makes great nutes, but if you do use canna I would recommend to continue tossing in a little of the cal mag.

You should also be feeding daily. Especially with 25% perlite. Coco works best if fed daily til about 25% run off. I am assuming light warrior is a soil, but you are still predominately coco and perlite. You almost can't overwater coco especially when cut with perlite but you need to continually wash away accumulated salts.

Your life would be much easier if you ran straight coco, with any coco specific a&b chem (or with botanicare pbp and cal mag if you wanna keep an organic sensibility), a zym, a root additive, and maybe sugar of some type (maple syrup, molasses, carboload, etc.), innoculate with beni's, feed daily, flush with plain water every week or two, start out HS about 1.1 ec work up to about 1.6, flush last 10 days just ro water (maybe some sugar). And I promise no prolems whatsoever with that strain. It does stretch like hell though.

Also, with the CO2 burner be on the lookout for powdery mildew. You could buy a sulphur vap and burn it 2 hours (lights off) once a week until 3 weeks before harvest and you will never see it in the first place.

help!

help!

Does this look like def, or burn, it's mainly the upper leaves tha big ones. I've been feeding 8ml/gal bio grow,bio bloom, alg-a-mic, and topmax, along with a heap of hum tea, I just flushed last week, I started off heavy on the nutes from day 1 so not sure it's burn, mainly due the them adapting I fed like 8 ml a gallon as clones just bio grow though. minor burn occured so I backed off, please help day 45 of flower only a few weeks left. I have went up to around 10ml/gallon, my recipe is calling for 16ml per gallon right now but that seem's extreme. Please help
