im gonna start doing my first grow and would like some edvice on my cabinet and lighting system.I am most likely gonna get a 400w hps kit from htg supply and place it i a closet cabinet that im gonna buy from ikea.Im gonna have the light sealed off on the top by a shelf that will have a pieace of tempered glass placed in the middle of it acting as my own glass reflector.I will have a pc fan sucking the heat out of the sealed area were the light is and another pc fan on the bottom for intake air as well as a circulating fan.Im still wondering if i should buy the 400 or 250.
