2 - 600w HPS with air cooled reflectors
449cfm vortex fan - fan is in attic - straight ducting from the lights through the ceiling and out a carbon filter
2'6" x 7' x 8' space (140 cubic feet)
Intake is passive - 6" diameter hole - outside room temp 76 degrees
Fan blowing over the tops of the plants
My problem is I can't seem to get the temp below 90 degrees - the temp on the floor below the lights is around 90 - the temp above the lights is 85 degrees. Do I need a larger intake? Any help is appreciated.
