heat/ventilation question?

im gonna be growing a bubbleponices system in a growlab 60 (5'3" tall) and im nto too worried about smell since my room will already stink from me smoking in it lol but i am worried about the heat...i want to use a 250w lumatek digi ballast with an air cooled reflector, can i just get maybe suck ALL the air out of the tent with one 300-400cfm fan to get rid of the heat from the lamp and replace the air (killing two bird with one stone) or do u guys think i need two separate fans, one hooked directly up the the air cooled reflector to dissipate heat and another to replace the air?

Anytime you can remove heat directly from the reflector, you're always better off. Sometimes, it takes a combonation of both to keep the heat down, but it doesn't sound like you're working with too much heat with only 250 watts, should be a little less of a problem for you.

I Use a 400 watt HPS with no cooled reflector and use a Can fan that pushes 424 CFM and my temps never over 79.. prolly dont need that powerfull of a fan for a 250 watt light

id rather be safe than sorry...maybe ill go with 2 150 cfm fans near the top of my tent just to suck EVERYTHING out...

anyone else got anything to add

I think a single 250cfm to 300cfm fan should work fine with a scrubber. Denver is pretty good climate any chance you can use fresh outside air? smoking is not good for plants. I always smoke outside.
