I was thinking of getting a General Hydroponics Aero2 setup x4. Space isn't an issue, I have about 2200 sq ft of available space to use up. But with electrical wiring issues, its not possible without having to re-rig the house with 220v. My current lighting system consists of 6 parabolic reflectors 5 1000w HPS bulbs and 1 1000w MH. Ooops gotta go ill finish this post when I get back.
