Hey sublime, i've got a closet grow going on running a 400W HPS but i've got a lil less space than you in mine.
Have got this hydro setup running in my cupboard, I have a vent and an oscilating fan which blows air around the closet and also out of the vent, do you reckon this would be enough ventilation or do you think I should do something 'more!'

Peace
