how much light to keep mothers alive?

so, want to have two little bonzai mothers, and wondering how much light i need to give them to stay alive, and grow a bit; all i need is a couple cuttings every two months

looking at getting this for my grow cab; the bottom would be two moms and two vegging, a little tight down there, but nice; hopefully that bottom shelf can be moved up; if not at least the nice thing about seperate doors for veg and flower is i can open the seperately, if one is sleeping and the other has light

i have some 26w cfl's. for the two moms, do you think i need more than one of these? more than two?

seems like it should work, im in the same situation right now. mothers in veg can accept much lower lighting than flowering or veg if you dont need them to do much. keep on 16-8 so you can keep them smaller. this is only theory and some reading so far since i just got to that point myself.
