The thicker the stem and the more nodes, exponentially are there more hormones in the plantlet to begin with. What makes more difference to me is clean procedure making the clones, and selecting clones that are at least 3, preferably 4 nodes or more and having a thick stem with extra growth cleaned up and clones all cut to same height, not splindly pissy clones. In a media I dont need to use gel, but do, as it will make more roots, in less time.and more reliably. In rockwool or jiffies I use hormone, normally I use hormone.at worst case even in aerocloners, id add some to the rez, just a dash of gel.but it made no difference as rooting would be so rapid.if clones are rooting in 5-7 days, does gaining an extra day make much difference, and if roots as as profuse as can be does hormone make a difference. Callous formation is quick and root bumps should be emerging by day 5.If water temps are too warm, make the pump run 15 on 15 off, if too cool, run all the time etc.My issue with ez cloner is not rooting time, a tree that would normally take 3-6 months to root I could get showing roots in 3-4 weeks, it makes roots amazingly fast, my issue was if a bacterial or fungal pathogen sets in, it takes out everything, fast, and that makes rooting never happen.and then no matter how much bleaching of pucks id do, or, the problem would always re-occur. A quick rooter would root in like 5 days, or rather be showing roots emerging. If water temps were not too warm and not too cold, and no microbial pathogens, a strain that would normally take 14 days would take maybe 7.
