View Full Version : CO2 in a 3'x2'x7' Space

I have a 36 cu-ft grow cabinet ventilated with plenty of fresh air. I keep reading about serious growers use CO2 injection. The products I see online cost more then I have in the whole project (have just found $400-$600 models for bigger spaces). Anybody have a lower cost alternative or words of wisdom or just bite it since it's that important? I can ventilate the box about anyway needed.

if you used yeast, sugar, water....what would be the proper way to mix it?

the most effective way to use co2 is to get a co2 tank hooked up with a solenoid and a timer... there are formulas to how long u need to run ur co2 tank depending on the volume of the grow area, just google it.... feed ur plants accordingly to the nutrient levels in there ppm 220 for young growth 500-600 for veg and up to 1500 for peak flowering

btw welding, party, beer and homedepot type stores all carry co2 tanks
