Setup: 1 1000 watt Metal Halide, 3 sets of 4 foot fluors, and an additional one for clones. Heat mat for clones, and a self fogging system. 75 lb co2 tank with a reg. 30 gallon rez from walmart with a 196 gph submersible pump, connected to a 12 output distributor for automatic watering of the vegging plants. The fogging system is just a rubbermaid sealed with a fogger submerged, an air supply, and two distributing hoses to keep both domes very humid. I have timer fog for 15 minutes, 6 times a day, but some time, I'm buying another digital timer to do 6, or more, 5 minutes fogging sessions.
