soil: Ocean Forest - I have 5 2 foot indicas in 30 days, no nutes, under:
light: 400watt hortilux blue, hidhut digital ballast, $200 + reflector

forget about lumens, forget about cfls, if you want proper growth without having to be a master horticulturist, it is all about spectrum and intensity (which you only get from 100watt+ cfl (not a 27watt=100watt bulb)). By the time you get 2 or 3 100watt cfls plus reflectors, you could have just bought a much higher intensity/efficiency mh light. With the hortilux bulb, you get proper spectrum

The results speak for themselves, 2 foot indicas from bagseed
How? ocean forest 1 gallon pots, 2 weeks under 100 watt flourex security light (home depot) + 1 daylight 27 watt @ 6" light distance. Transplanted to 5 gallon ocean forest, 2 weeks under 400 watt hortliux blue @ 1foot. 2 feet, 7-8 nodes each. Easier than I thought. One thing, I wish I didn't waste so much money on cfls up front, would have done just as good or better with the mh @ 2-3 feet light distance.
