Making the actual grow box is the first concern. A few boards, some plywood and some nails should get you started. And just make it up to your dimension, box like. Your going to need two fans (computer fans work well for smaller grows), one in the bottom to suck in air, then one in the top to vent air out. Air circulation is key. For your size, I would recommend cfls (compact fluorescent light bulbs) for lighting. It will depend on the amount of of plants that you want and dimensions before I could tell you wattage. Also an oscillating fan would not hurt either. A temperature and humidity gauge is helpful as well. The inside of the grow box should have some reflective material on the inside walls to reflect light, not tinfoil, white paint works very well, as well as Mylar. That should give you a good start. I recommend checking out some of grow journals or "cfl grows" here on rollitup. There is A lot of useful information that you can read and see from people that have already done what you want to. Hope that helps, Happy toking
