I was just curious how much of a difference a 600 watt or 1000 watt hps lamp with digital ballast? I understand MH are very hot so floros would be a better bet as far as heat and energy for veg. Would a hps lamp be to much for a decent size closet? (say 6'Lx6'Wx8'H) If ventalation were needed what are some easy ways to run 6 inch hoses without tearing up walls and not looking too suspicous. And also any filter recomendations to mask odors would be appreciated. Thanks !
