Ya u should do it on your next run bro, winter is upon us, if u run a room like ours where u circulate the air u only need to run C02 during the cold winter months when there is very little C02 in the air, the air is very cold and dense. and holds very little co2, u should run C02 from about November to about march, to compensate for low C02 levels in the air.......GM
Great info. Never thought about this but makes all the sense in the world.. Thanks for sharing, I'm always saying I get better yields in the summer runs..
