Thanks to all for replying. The intake air is supplied from the basement surrounding the room, I was hoping that this would help keep the humidity up and the temp down. Unfortunately, I haven't seen the humidity above forty percent, and the temps were holding fast at 75 for the first two weeks, but now they've gone crazy. Luckily the plants don't look as if they notice yet, I haven't noticed the growth slowing. As for fans, I have an 80cfm inline fan blowing in, from the basement, directly across the tops of the pots, and a 12" oscillating fan to stir it further. The lights are the econo light 150 watters (five of 'em), so venting the hood is out of the question.
I guess the option I was trying to avoid is the only course of action. I need to up the cfm on my ventilation fan. I was trying to keep the sound of the fans down, and the 180cfm barley keeps quiet, but in the interest of not wasting my time and genetics, I'll invest in a stronger fan. Running a line to the outside is out of the question because of stealth. Tomorrow morning i'll be there again, I'm hoping the new colder temps at night will help me out some.
Another thing. Based on the idea that the plants don't breathe in the dark, I turn the fan off during the dark period. The 80 cfm supplying fresh air still runs. Being that they're autos, its six hours during the night. I could switch that to the day, also, but I don't know how much that would affect the high temp.
