I been having a 90% success rate with using rapid rooters, olivias cloning gel, clone dome and heat mat w a 4ft t5 fluorescent, foliar with aloe vera juice mixed w water.
I use clonex and root riot cubes. Its been a very long time since I lost a cutting and I get roots in 7 to 10 days. over the years I have found 2 things make a huge difference in cloning sucess and speed: use a fresh clean razor blade every time and keep the root zone at 79f. a clean slice and the proper temps are key, at least in my experience.
uh like take root or something from walmart, split a little bit of the stem put it in water dip in powder then just put it in a solo cup of your soil. with a heating pad roots in 7 days with me 100% out of 50 clones so far.
