I bought the Coolcab and i'm doing pretty friggin good with it. I personally love my unit, and have no complaints. I'm not sure about the homegrown hydroponics since i've never bought anything from them, but i remember when i first went to their site along time ago before I ordered they had pictures from sunlightsheds.com on there. I called sunlight sheds and they showed me proof they had stolen the pics and are in the process of suing them, but thats just what i was shown/told.
