haha thats funny..
and co2 is always beneficial to speed up photosynthesis.. too much can kill your plants, so can too little..
and no co2 does not lower potency, but growers tend to get the temps from 85 to 90 with co2 because it allows for greater respiration, thus faster growth and higher yields.. thc is known to begin degrading at 90 degrees which in turn lowers the potency..
USE GOOGLE
just a thought
