i think this chick is on to something.... maybe you should check it out?moms and clones do best with low amounts of light. like one 23w cfl per plant, or one per tray of clones (one of your cabs).
you want your moms to stretch a bit to get the best cuttings with long stems. you want your cuttings to have low light, so they root instead of continuing trying to grow....
imo, if you can get a small enough fixture, t12 tubes would be your best bet, one cool (daylight) and one warm (kitchen and bath) per chamber.
i think you can get them in 18'' fixtures, i think even 12''....but don't quote me on that. i know i've had some minis...i hear you sweetheart....but t12 tubes are way too big arent they....?
