Between 78 and 82 is perfect

it's 65 f some time 71f

If its 65 outside the room try to exhaust the warm air from the grow room more vigorously (stronger fan etc.) and let the cold air replace it.

turn off your lights. thats helps with temps. ofcoarse. youll grow horrible marijuana like that. lol

What kind of reflector do you have? Maybe you could get an enclosed reflector that is attached to your vent system so the heat from the light isnt vented straight into your grow room.

was just looking i think i mite get a air cooled hood
