Actually I think there may have been some confusion between me and my friend regarding "fresh air". I personally assumed that fresh air meant air pumped in from outside but he says the "fresh air" from outside of the tent(IE: my room) will do just fine. I think on my next cycle I may get a better tent and actually use a C02 canister and such.what!!!
the plant will breath the c02 in and breath oxygen out!!!!
the room will be full of oxygen and no c02!!!
is that u mainliner?
