had the lights on for about 3 hours yesterday,temp remained at 82. i have 1 computer looking fan, not sure of the strength, at the bottom blowing air in, and a 265cfm blower sucking air through a carbon filter, then pushes it through my air cooled light fixture and out the top corner exhaust. i'm all set to go, i'd like to get it more quite though. anyways, 3 of those older seeds i mentioned before look like they're going to germinate
