depends on your cooling capabilities. My tent is the same size and run a 400w with no probs what so ever but with a larger volume fan for the lamp I could prob run a 600w
I agree that if you can exhaust the hot air, a 600 Watt is the better option. Also to consider, NextGen digital ballasts work for 400 and 600 watts in either MH or HPS for about $280. That will give you additional versatility.
A 400 watt would probably do just fine and be much less problematic to vent.In that space , a 400 watt HPS should do just fine. The heat differential will be worth it in my opinion.
