None. This is a cutting from a low branch I cut from a 20 yr old seeded plant which is in pre-flower two weeks ago. I used the nice top from this branch to attempt yet another clone effort. The top has not shown any rootlets yet, but this spindly branch with hardly any leaf growth rooted in my Aero cloner. I've been so fed up with trying to clone this mother plant for months, just for kicks, stuck this stem in the Aero cloner and less than two weeks later it sprung rootlets.
Don't shock easily but I could not believe this relative nothing of stem actually has roots. It's in that 4" peat pot, and I am awaiting a show of more roots thru the bottom to see if it will be a viable plant.
