Made the fan pull fresh air in from the house to the room, it's only a 6in inline home depot fan but it is pushing some air in there. I really want to buy this co2 emitter and seal the room, using the 8in can fan to push air through the hot hood and through a charcoal filter recirculated back in the room. Do you think this will work? Also the guy i'm buying all of this off of told me to use his drip system(instead of flood and drain) and use rockwool instead of planting right in the hydroton, as the rockwool will work as a ph buffer in case i mess up the ph. lol Does that sound right? I don't know how i'd make the rockwool fit into my dwc bubbler/cloner. I apologize in advance for making things too complicated.
