Most growers let the CO2 fall onto their plants and it works well.

dang, i could've yielded more but i wanted to see this shit start flowering... i really don't know, i'm on day 44 and the buds i can see are:
7" long
4"long
5" long
5" long
3"long...
on the fattest point they are 3" wide a piece and feel pretty damn solid....
i don't know how much that can yield...
i just say 1/4 oz cuz it's worth 120 bux round here, which is bout the same amt i've invested in this grow.... hehe... just hoping to break even...
ahh so doing 3 gal buckets of y active yeast the c02 will fall as in the dry ice then correct?
patience is key.,.,let it bee.,and itll get ya high like a bird ina tree
