Ive tried a lot of different methods to cloning over the years. I've found what works best for me,. I think that thats what it comes down to, whats best for YOU. But anyways heres my method. Right now Im getting 100% rooting rate w/ Hashplant x Haze, Kushberry x Skunk and Violator Kush.
I run a small bubble cloner. I use 1/2 tsp of cloning solution to 1 gallon H2O. I ran out of cloning solution and used just H2O and still got 100% it just took longer to root.
I take cutting and make a slit up the stem w/ razor blade and put in cloner. The only light source on the cloner is a single 23 watt CFL that runs 24 hours a day. . I also have a heater in the cloner to keep the water warm. Once they root they go under a 150 watt HPS on a 24 hour cycle.
