Zandor,

I get the fun out of growing the stuff. I have way more smoke than I could ever smoke laying all over the place.

I find bags of weed in my winter coat pockets from year ago. Wife cant stand it. But i get stoned and forget where i put it, so i just go to my stash poing and fill up again.

So yes, I too share it....

Anyhow, I have built my cabinet and have spared no expense. I really was thinking about the co2...but i understand:

1. co2 is used by the plant during light stage.
2. the co2 will pour to the bottom of the air level.

Well, since my fans and exhaust are running full board during light sessions, will not the co2 i put in just be sucked right out?

I realize if I have a room that might be different, but how could I effectively gas the grow space and know it wount be sucked right out.

I have a 250cfm exhaust with 2 passive 4" intakes.

my veg chamber is 3.5 sq ft and 30 inches high.

Please let me know what YOU would do if YOU were in MY situation.

THanks Zandor
