tru man - i wasnt tryin' to sound like an ass... sorry if I did.

I'd like to see someone do the yeast method with a ppm meter... even though those cost more than the regulators

i dont even have co2 yet - but i've been looking at it... I have 2 problems with the generators... 1 - they make heat, which i'm actively trying to get rid of... and 2 - there is an open flame in my grow room - i would just be worried about comming home to firetrucks in my driveway.

I think the tanks would be the best (for me) because you can put them anywhere, and they'll last for a long time.. I dont have a lot of floor space, but I do have some ceiling space.. (i got my carbon filter on the ceiling already)

anyone know what the ppm of co2 is if you just chill in the room for a while? my grow room air circulates from my office - where i spend all day - so i think my plants get all my co2 imp: just dont know how much it is - cuz i havent invested in a ppm meter.
BloodShot420 Reviewed by BloodShot420 on . CO2 - how to? I have heard a lot of good things about CO2 -- So, I decided to mix one myself. My question is how do I use it? Do I just spray my home made CO2 into the plant? or do I have to add some water afterward? please advise. thanks Rating: 5
