Pretty much 100% success rate just one more to root but dont even need it. Aerocloners with aquarium heater are the way to go.
The other few cuttings are a different strain, kongs krush by green house seeds. Seem to be a nice breeder. It was completely limp leaning over the edge of cloner, bounced straight up overnight.
My last attempt root riot I pulled all the non rooted cuttings after 3 weeks maybe 4 and put in aerocloner. No water heater, no roots after two weeks or so.
The manual says water temp fixes it 99% of time. To expect 100% success. Its for real! Im hooked on aercloners now. It makes an important part of the perpetual grow work or else it wouldnt.
Pretty confident and will be suggesting this to people struggling to root cuttings, wish I knew this sooner. Also that pool shock keeps things fresh.
