Noob here but I do a slower but has been 100% successful thus far. I am sure it has some name but I just do you cutting, split the stem or not (doesn't seem to make a difference), dip in rooting solution, and then fill a dark glass or cup with some filtered water and top with syran wrap. Stab a hole in the top and stick the clone into the water with the leaves of the cutting outside the cup and the stem just into the water. Place somewere with moderate light, like a window sill without direct light, or even on the floor in any room that has ~10hrs of light. Do not put them under HID or HPS or they will wilt and die quickly. Lower light seems to work as they aren't working on photosynthesis I guess, and more working on rooting.
About 2 weeks later you will get roots (or faster, the strain I have seems to take 2 weeks), and then just put it in soil or the pot it will harvest from.
At this point I keep it in indirect growing lights and spray it regularly until it roots and grows. 2-4 weeks later she is ready for bloom.
Not fast, but doing it this way I have yet to loose a clone and have had to kill a bunch off because I was getting too many.
