I'm not sure, but I really doubt that CO2 will 'decrease' potency of the buds.

I would be inclined to think that either it 'increases' the "potency" of the buds, or it enables more vigor for the plant itself to "increase" the potency of its buds.

I think it can reduce flowering times by half (I think!)... and it's also very good for vegetative growth.

Wait for Zandor's input... he's into CO2.

BTW: Dude, CO2 will kill you... and everyone in your house if not treated with respect .... you can have no leaks... no semi-sealed grow room... I guess you know this... but just in case...

Please let us know what you're doing and how it's going... I'm very interested in using CO2 myself when the times comes around.

Best,
