I have a 4 ftx2 ft grow area with 4 plants. I'm running 4 48" T12 flourescent tubes above plants and 4 tubes horizontally across the back wall. If I remember correctly, all 8 tubes are 6500K. I'm planning to flower my plants within a week and would like some advice on the kind of tubes I should get. Should I replace ALL tubes with warm spectrum tubes or just some? What color ratings should I get? I plan to use all flouros for my grow, so don't bother with a "get hps" response; it does me no good. Thanks and happy smoking.
