Everyone it seems has a "method" for cloning. Personally I think a lot are over rated. I have had at least a 90% success rate in rooting clones, and I like to keep it simple. Angle your cut (I use scissors) and use the rooting compound of choice (I use powdered "Stim-Root"). Wet the cutting, dip it in the powder and plant in a pre made hole. Make sure your medium is pre soaked. I like clear cups (as pictured). Once you see the roots through the cup it's time to transplant.
These are the newest addition to the closet. The left(and below right) is a shishkaberry and white widow on the right(and top right). They are in a 2' x 3.5' x 8' closet with a 400w MH. By the second week the widow had grown another 6" and had to be "bent" to avoid being burnt. These are now in their third week
