Ok I have started to grow and I am having all kinds of problems with the tempeture. I am using a 400 watt hps and I cant for the life of me keep the temp below 90*. If I put a fan on it drops the humidity way to low even with a new humdifier i just got. is there any ways to control temp without using a cool tube? I am growing in a 8ft by 5ft closet with an ambient temp of around 65* any suggestions on what I should do would be greatly appreciated. I am about ready to switch to cfls.
I need your help!

a pc fan close enough to cool an hps will burn.
you need to vent the room. vent to a attic or basement or crawlspace or something.
you need cool air coming in and hot air going out.
if you cant do that get or cool tube.
or do nothing, 90 isnt that bad, pot is a tropical plant.

Yes you can have heat problems with CFL's. I have to leave the door open for my veg closet, with the door shut the temps shoot to almost 100F within ten minutes.
Put the fan back on - if you need higher humidity, try putting a bucket of water in there, or hang some damp towels.
