CO2 bag, tent grow, one plant in 32x32x63 tent

[grassy007]

First of all, I'm not shelling out big cash for a CO2 tank and regulator. If you have the bag hanging over your one plant, doesn't that impede the plants ability to exhale oxygen during it's sleep period? So, I nixed having it inside the tent, but instead have it dangling outside at the bottom intake vent which has a 1200 rpm pc case fan bringing in outside air. The intake case fan is on a timer and turns off during sleep period. I have a Vivosun 190 CFM at the top to exhaust air running 24/7. What's the definitive conclusion about CO2 bags? I'm not about to shell out $100 for a CO2 meter either. I have nothing to compare the growth to because I set it up from day one. Has anyone here used a CO2 meter with their bag? Did it raise the Co2 significantly? $32 dollars worth???


First time stealth grow. 3 gallon pot, 1000w Led. Day 40 of Pineapple Express clone.. Slow grower, I thinned it out. It's starting to get definitive spear potential. I'll veg it 10 more days, then switch to flowering stage and SCROG.

That doesnt look like a 1000w plant brah. Especially for being over a month old. Whats the brand light? Looks good, dont get me wrong. Just rather small for a 1000 watter. As far as c02 implementation, im actually looking for a solid answer on those bags as well. I built a hand full of the "c02 generators" (yeast, sugar, water, a couple soda bottles, and aquarium tubing) they didnt do shit fwiw.

BestVA 1000w. I agree the growth is slow. I may not have been feeding it high enough doses of nutes. I've always held back after reading how some cut their nute doses in half (might have been a mistake). I may have been doing that too long. I'm also raising the light up another 10". Even tho the leaves aren't burning, I've read that too intense a light will stunt growth. I monitor the PH and everything. Good loose soil. I feed them Mag-Cal regularly. You can read the reviews on Amazon (especially the negative ones) as to if this LED light is up to par spec wise. I want to see less narrow leaf growth, even tho this is a sativa plant (leaves still too narrow). I'm still getting white tips on new growth even tho I'm adding Cali-Mag and FF's Big Bloom (maybe not enough). I'm still trying to figure that one out. First time stealth grow. I hope there's still time for the plant to bust out some before I switch to flower stage.

P.S. I ditched the Co2 bag altogether. With the air circulation and the exhaust fan, I just don't see how placing the bag just above my plant would allow the Co2 to waft down over the plant. The small amount of Co2 gas would get blown upwards and sucked up by the exhaust fan. A waste of $32 is what I think.

I'd get everything else dialed in before even messing with co2

How far is your light from the top of the plants? Moving the light 10 inches is going to reduce light intensity quite a bit. I checked out the amazon listing and they suggest 24" while some peeps that answered questions there said they could keep it even closer

Gotta have a sealed room for co2 to make any difference -- and sealed rooms need air conditioning.

I've raised up the light to about 20" from about 16" inches. I sorta doubt my problem is too much light intensity, but for experiments sake, I raised it up to 20" from the top of the plant. There was NO sign of leaf burn at 16", but then again I'm willing to try 20" just in case my slow growth was being caused by too much light intensity (BestVA 1000w led). I ditched the co2 bag altogether.

She looks really healthy but she's lanky. If this were me, i would actually be trying to inch that light closer and then back it off a couple or few inches the moment i see a sign of heat or light stress. I would measure that distance and know thats my sweet spot. I'm after the strongest light intensity i can achieve without negatively affecting the health of my girls.

A plant can only handle so much light, raising the co2 levels increases this limit. You are using about 130 actual watts I believe? This is FAR below the amount of lighting that's required for co2 to make a difference.

Just thought I should point that out..
