here's how i clone and usually get 90-100% success>>>

articles needed>>> klonex, peat pellets, a large mixing bowl, DISTILLED water, a nail and a very sharp knife or razor blade.

take cuttings to the cloning table and cut them down to no more than 6" total leaving as many small branches on the stem as possible...i try to keep the stems under water while trimming them to size so air bubbles don't get into the stem. these are root sites so the more side stems the better. cut the small side stems off at the main stem then immediately dip in "klonex"...i like to leave the stem sitting in the jar for half a minute or so. then take the stem and immediately move it into a prepared peat pellet (i prepare them by thoroughly soaking in water then taking a nail and 'clean out' the hole so the stem slides in easily without bending) then gently place into pellet far enough so the bottom of the stem is close to the bottom of the pellet but not all the way through. once all clones are processed and in place i keep them in a tray with a small amount of water kept warm in a closet under flouro's. after 2-3 weeks you should have a well rooted clone that's ready to be moved into the veg room. the mother plant is always healthy before taking clones and i never add extra nutes once the clones are in the peat pellets as the mother plant will have already given all they need for a healthy start. once they're rooted and settled into their new individual pots they get a small dose of ferts and a liberal dose of "super thrive"...which i also give a healthy dose of to the mother plant appx two weeks before expected clone date.

good luck and hope this helps...
