Lighting for clones

Hey all was just curious if 2 - 2 foot tube fluorcents (G.E. Ecolux F20T12 to be exact) would be suffecient lighting for my clones. planning on having about 30-40 all together. Oh yeh, those bulbs are 20w a piece and make 875 lumens each and have a 5000k color temp. Any help would be great, thanks.

I'd use one myself, for cloning anyway. Just untwist one, once you get roots twist it on agine.

I found less light quicker roots. I also keep a piece of landscape fabric, the black stuff, but I sometimes cover a part of my humidity dome, reducing light even more. Good luck!!
