C02 question

[Chilkoot89]

how much of it is necessary for 2 grow boxes (one vegging one budding) that house 6 plants each?

and

what would be the most most effective way of producing enough Co2 on a budget and in a limited space?

Well on a budget better ventilation will always help. Bigger fans and intake and such. But you could get a CO2 tank and regulator and CO2 PPM reader but you could pay upwards of a grand or so, and in most states you need a license to buy a large CO2 tank. Breathing deeply in your grow room when your in there can help lol But yeah, more ventilation.

I would only use Co2 for budding....not really needed for veg.

Sugar/ Yeast method....... Take sugar and desolve it in warm water....put in a 1tbsp of yeast to 1 cup of sugar per 10oz of water.....i fill half a gatorade botte.....put a hole in the cap and shake....bubbles will soon form and co2 is created....

I have a few of these in my growroom....i have 1 above plants and 2 behind fan blowing onto the plants.

1200 ppm 1 hour after lights on til 1 hour before lights out....

if u use it i recommend controling it and measuring it or scrap that idea... an error will cost you your crop...

any reason for the 1 tbsp of yeast and not a lower amount? i mean, the yeast is dirt cheap, so i can see why you would do a lot. I thought though they were very good at propagating so even a little amount of yeast will reproduce enough and reach the asymptote limit for how much yeast per given amount of sugar that is possible in like a day or two. Just wondering since I only bought one small packet of yeast and figure i would just add them little by little to the bottle when needed so that i dont have to drive to the store to buy more packets.

u can do as much as u want...I just feel that this was a good mix for 20oz bottles...I used wayyy more when i did it in gallons...

I've never heard of that before! nice! Yeah, for flowering and only when lights are on.

i just picked up a killer CO2 i use 1500 ppm 1 hour afer light on and i usally kill mine down to 200 ppm until light off i go through 6 24oz bottles a day but my buddy works at the shop but im upgrading to 3 2lb tanks soon thats the biggest the shop will fill i wanna get 10lb tanks but ive had it for 4 days im at 28 days flower and alll i can say is wow i swear by it now my system was 449 well worth it especially after the dynamite harvest im doin 50 lr2s and a couple sensi stars for flovor
