Update your house Holmes. Fuses are old school. Install a breaker panel and install some high amp service breakers.
True that, is the only way I could use the 400 watts without an a/c be purchasing a tent? I'm really lost on how to ventilate this monster its in a closet that already has a hole in the wall to vent threw
even then its gonna be a pain to keeps temps below 80 if it gets above 65 in your house...always good to have an ac if you can... if its cold enough keep the heat in your house at like 60 and suck cold air into the room
Does anyone know an approximate difference in temp from a 400 watt to a 250?? I can apparently use 400 or 250 in my ballast
