I use the cheap rooting hormone sold at local home improvment stores, 4 bucks and it will last for years if you take care of it. The gel has a shelf life and should be stored in the fridge.
I use rapid rooters and can get rooted clones in 5-6 days, it is so fast, and I have had 100% sucess rate and not even one leaf start to yellow on me.
I place the small amount of cuttings in a small dome and set them on top of my 4 ft flourecent tubes. Roots in 5 days....Good luck JR
