digi ballasts will run regular mh too, tho right? i thought conversion bulbs run in ANY hps ballast?

the reason id run more crops with cfls is that by having the second room unaffected by the 12/12, id be cloning and vegging seedlings so that they could rotate in as the old plants begin coming out for harvest.

also, any way to direct the hps more downwards? alot of light is going EVERYWHERE in the room, and if i could aim thet extra 10-15% down, itd be nice.
ie: whats the best shape for the batwing: semicircle or 1/4 circle?
