Heat, Ventilation, and Lights

I got my grow tent all set up yesterday, its 3ft X 3ft X 6ft. All I need now is a light and ballast. I know I would be better off using a 400 watt light over a 250 watt, but heat can be an issue. The tent is IN a medium sized room. The reflector is air-coolable and I have a 145 cfm blower attached plus a circulating fan to blow the tops of the plants. Do you think a 400 watt light will heat up the grow closet/room too much? :rastasmoke:

As long as light is cooled which you say it is and temp can somewhat be controlled in room you will be fine. I have 2 tents/closets in 1 room and both run a 400w light and no probs.
