Just a single small CFL is enough light for a cloner. Too much light, and they grow SHOOTS, not ROOTS.

I think if you want to take your plants to 18" in veg, you are looking at a whole different ballgame. Even a good T5 flouro will have trouble penetrating that canopy more than a foot or so. I used to bring plants to 10-12" in veg under shop light T12s and that was definitely as far as I'd recommend going with tubes. Maybe 14" under T5s? This is speculation though; after plants hit a foot I either flower them, throw them under my MH400, or toss em in the rubbish if I've got no space, lol!

Remember there's lots of ways to skin a cat, and you can configure that closet any way that works. Hint: when you hang the mounting hooks in the ceiling studs, hang EXTRA ones, and attach lengths of chain hanging down so you can easily add more hanging stuff (lights, fans, ductwork, power cords) without having to remove EVERYTHING from the closet and go hunting for your stud finder and power drill!
stinkyattic Reviewed by stinkyattic on . Keeping mothers and Lighting In the process of finishing up my grow room and having a problem choosing lighting for my mothers. I'm going to be keeping my vegging plants and mothers in a 6' by 3.5' closet. About four feet of that will be vegging plants, leaving a 2' by 3.5' area for keeping mothers(plan to have 3). I will only need 8-10ish clones from each mother every 1.5-2 months or so. Would a 2' four bulb T5 setup be enough lights for my mothers? Also the door on the closet is going to have to be shut for 12 Rating: 5
