no, you shouldn't. you do not want clones to try to grow. you don't want them in the dark, but a 20-30 watt cfl a couple of feet away is plenty of light for clones. too much light and they try to grow new leaves, you want them concentrating on growing roots.
taking a clone from a flowering plant is called monster cropping, and they produce very bushy clones, suitable for mothers most of the time, but they do have a harder time getting started, and will have at least a month of "reveg" time, producing weird leaves till the flowering hormone gets out of their system.
also, give them at least 6 hours of dark a day, dark is when plants shift to root growth in a normal environment
