I think most people that have cloning trouble have it bc they over complicate the situation, I know I did. I have an aero cloner and it works. ive used rockwool and rapid rooters and they work. Clonex, Olivias, it all works. But remember K.I.S.S. What I use now (with 99% success) is 2 clear plastic shoeboxes from wally world, one with holes drilled in the bottom for drainage, filled 2/3rds with sandbox sand, the other flipped upside down for a dome, the cheap rooting powder and sitting near a south facing window for light. Cut em, strip em, dip em, stick em, n mist em daily. I use the same set up for flowering shrubs but on a grander scale (1000+ cuttings at a time). Theyre super easy to scoop out of the moist sand and the roots never tangle, even with them only 1" apart.
