Yeah...I must have same book...Marijuana Botany..By Robert Connell Clarke...The Propagation and Breeding of Distinct Cannabis.

I haven't tried it yet, was hopin' to hear from anyone who has tried it...and what their results were. If others are interested I will post the Technique for all to peruse. Looks like a great technique but have never heard of anyone using it. It looks very simple, no extra trays, cubes, peat pucks 'n' such.
And the correct term is air-layering.
