yeah 1 foot is a good height to shoot for when flowerin. and as the grnman said.. MORE LIGHT. with all those plants you need many more. get some y adapters and and at least like 6 more bulbs. then get more. get the idea? ive got 4 plants about the same age as yours id say. and im running 8 cfls, and 2 tubes on them. and i need MORE. workin on getting more. thats the thing about cfls, they require a bit more upkeep.
anyway good luck!
Ery.
