I will put 24 clones in round transparent box.They gone be in that box only for 2 weeks(when i see roots) i will transplant them and put them on better light(HPS).They gone be in really small peat containers,and the box is about 30cm round.I asking because i was never work with CFL,and i think that this can work(only for clones),later i dont have problems because i have good light or sun.Thank mc260377 on answer,also if somebody else have something to say your are welcome.
