Anything from 30w(True) CFL will be fine for seedlings and Clones....
Peace
2x 30w CFL 1x 2700k and 1x 5600k would do you great(for beginning stage)and a lot of growers mix the colours/spectrums...And before anyone jumps off about colours and spectrums and watts and Par and Lumens...Etc...Leave it out!! K.I.S.S.
CFL's do need to be close to the ladies...but not too close in the first week...say about 6-7" away..but after a few days or week you can lower to say 2"-3" use your hand at the tops of Ladies, if hand gets Hot! then so are you Girls..
Peace
