if you want clones off these no problem u can. i would wait until the lighting is improved. and read up on the coloning on this site lots of different ways to do it. now do you know if you have all girls already? now if u dont know if there girls take as many clones off them as u can. and if done right itll be like topping all of them and the might help increase ur first yield alittle. do you have a local grow shop or hydro store. search around this site for a thread on a cfl layout that is said to rival a 400watt hps. and make sure that the cfls are 2700 for flower and 5700 for veg. i use 2700 only but some say use the higher kelvin rating for veg.
