Okay, I have a 400 watt hps system (ballast, reflector, bulb, etc.) and it works just fine, just plug and grow. Problem is now I need to build a grow box that won't take up too much space but will be able to ventilate the heat well. How do I set up a grow box that will be no taller than 4 feet tall and about 3 feet wide and 3 feet deep and still keep the temperatures at 75 to 80 degrees?
What do you mean "how do you setup a growbox" I mean that's a pretty big question, there's thosaunds of ways.. but 4 feet tall? that's probably not gonna work out. I'm making mine out of wood and sheetrock right now, almost like an extended room.
