There's got to be at least 1 thread on this here. If not here, check out the tokecity.com forums...they might have it there.
just take a cutting, from one of the small tops that grow after the fan leaves have matured and the easiest way is to just put it in a cup of water and keeping humidity high, and putting it under a light thats not too bright, and you also wanna cut the bottem at a 45degree's it helps with growing new roots.
from the "top" of the plant, more commonly refered to as growth tips.. actualy. here watch this video http://ganjaguerrilla.net/cloning101.WMV that should answer all your questions, copy him exactly and your good to go I dont think he mentions it.. PH should be 5.7-5.8 for clones sure as hell can, infact this is great because these type of clones go back into flower faster....
i have just taken a few cuttings and i'm using cfl light bulb. so many inch's should i keep the cuttings from the light?
cuttings from my experience tend too do better in indirect light took mine about 8 days to root under one 23 watt daylight cfls and it was about 8 inches away from the cutting, having high humidity helps with rooting.
