Without measuring it again my room is approx 7x8x8 , and if it matters, on the second story of my house. Since it's been hot out temps have been going all the way to 92 with lights on. (And I'm not even running the HPS yet)
Changed my lighting schedual to be off from 11am to 5pm , and that has brought it down to 82-84. (78-80 when lights are off). I don't have central air, and cannot run the A/C that's in there. The door is wide open for fresh air, and I have two oscillating fans on the floor. Last night installed a 250 cfm fan to help exhaust heat - it's in the back about a foot from the ceiling. However - looking today it appears the fan is not helping to cool the room at all.
A friend suggested it might have to do with pressure - so I tried it with the door shut, for 45 minutes - temps went up 4 degrees in that time - so no door shutting.
So my question is, why is the exhaust fan not bringing the temp down at all? Is it not big enough for the room?
