need help cooling growdrobe (wardrobe)

What size is the grow room? What watt light? Whats the cfm of the fan?

Ive got a robe setup, on 12/12 atm and during the 12hour light period i leave the doors open with a fan on it, when the lights go off i close the robe and leave the fan inside it. Never had a problem. But post some dimensions on your setup

grow room is 2 foot depth 6 foot tall and 3 foot long im using a 600w hps in a coolsun reflector and 500cfm fan getting hot air out of cooltube and another one on the other side which is about 290 cfm i think
