by all means I'd rather call it an interesting experiment... and it's not it doesn't bring results (for example, honey consists of a lot of different substances - IF there would be one in it that would be poisonous to plants it could reveal such by a 0 root outcome) just that this observation wouldn't possess a lot of power to back itself up...
but it could incite others to do somewhat larger experiments, so thumbs up to the OP.
BTW interesting links, for sure a good read
Nice info here
IRRC clones cut from lower branches - the ones that mostly give popcorn on somewhat larger plants fulfill these points better than top- or middlepart clones? However, sometimes these cuts show signs of light deprivation and long internodial length and to my experience, these root not so well. (these that usually have a more "woody" outer stem material and usually turn yellow leaves at some time.
@OP
also somewhat remarkable that they root well under 12/12 - under what light-time has the mothe rbeen under when you did make the cut?
