correct me if im wrong but i thought that honey is known to stay fresh due to antifungal and antibacterial effects, infact honey stays edible for many decades when stored correct, however it will burn the crap out of your plants if yer not carefull ...Honey will cause either fungus or bacterial issues.
another question when ye cut the clones in 45° angle as i was told at school, do you do it just under or even partly through an internode? cuz if im not mistaken thats where the highest concentration of stemcells are situated and that should help in the speed at which they push new roots
