how much does C02 increase yield??? also what does it do??

What does supplementing co2 do for the grow? need it for the whole flowering cycle or is the last month good enough???

any rough ideas how much co2 increases yield???

If you have all of your conditions optimized than you will see increased production in growth and flowering. If you don't have your conditions right it doesn't help much or at all. There is a long thread CO2. Let me get the link.

cool. looking forward to it. i'm deciding between a generator or a tank.

C02 increases have been being studied as a "SHOOT DOWN" to the greehouse gasses theory (global warming) where actual studies by NON STONERS have produced a basic increase of at least 50% "i think" but with this much information in one sentence you should be able to have a field day with Google now and see for yourself.

P.S. no they don't use MJ in their studies lol that would be great
