I can't believe all the people who say HPS and MH are THE WAY TO GO!!!! You can build yourself an amazing light rack out of t8 flouros (512w) for under 100 dollars. They give off less heat than HPS and MH, plus you can put your plants right up to them! There used to be a guy named DubPhiend on overgrow, and he was master of all flouro. He converted many a grower to "the dark side" aka fluoros. My next cab is going to be a dual chamber 1024 w 48" T8 setup(did i mention full spectrum? -not quite, but a nice array of bulbs with different spectrums). I have a thread about it in growroom designs and setup. I should have my grow going by June, so if you remember, come check it out and see the magic fluoros can do. The point of this was to open people's minds to cheaper, possibly better ways of growing. Hope some of you become more lenient to fluoros.
Peace and stay blazed
