Ok, I bought a 48" cabinet from lowes for 120 bucks.. Its got 2 grow spaces of 22x21x37inches , so roughly 24 cubic feet of grow space. I have a 15" space on top for nutes and supplies. The two Grow spaces Have seperate grow containers. Each holds 3 gallons of water in the reservoir.

The lights for each side are 125 watt Florescent with a reflector, and the other side has a 400watt HPS with ballast. at about $180 and $150.
