i remember studying that the Egyptians used honey as an antiseptic and many other uses..
i think it would work. it protects the area that you cut from drying it out.. same consistency as rooting hormone, loaded with simple sugars for a plant developing roots may use (i say may, as i really don't know the micro biotic activities of the rooting process, and don't have the energy to research it right now) so it seems very plausible. I am taking clones on wed.. or thurs..next week.. i'll take some and use honey and see.. if you are interested. i grow in hydro, rockwool cubes can be easily peeled apart to examine the roots to check on development too. i have no problem ripping a clone out of a block and see how the roots are coming, and stick them back in the cube.. and still never lost a plant. they are pretty versatile plants.
edit: never mind.. you already have someone helping on this taking clones sooner.. i'll subscribe, i'm interested.
i know just water works.. but i like the added "peace of mind" by using something.
