Tap water. 6.0 Formulex at 1/2 strength. Foliar feed with formulex at 1/4 strength. Clonex. Diagonal cut, scrape 1 inch of the dermal tissue lightly with a scalpel. Dome on for 10 days. Half open 2 days. Open 2 days. Pot on. 2 week fully rooted clones with about 6 inches of root mass. 100% success rate.
I have to say the biggest single factor in healthy cloning though is to take a good cut in the first place. Bigger cuts root faster and better in my experience. They need that extra set of leaves, that the cut can cannibalise as it is rooting, So I like to take cuts with 3 sets of leaves, with the bottom one as a sacrificial battery. Another great tip is if you can take a cut where the area to be rooted contains a node, you cut the node off and those areas are excellent sites for root growth with the growth hormones already present there.
