So the commonly accepted wisdom is that when taking clones, you should do so from a lower, developing side branch; the closer to the bottom of the plant the better. These cuttings will be the easiest to coax into developing roots. My current situation is that I really don’t have any of those types of branches any longer. I’ve done many rounds of topping combined with trimming away of undergrowth. I did not actually anticipate this but I am now left with a bunch of apical meristems. I know that there is really only one true apical meristem but since I topped it so much, there is not one dominant stem, but a bunch of virtually equavalent tops with little to no undergrowth. I had no choice but to take clones from these top branches. It’s been seven days now in the aero cloner and I don’t see any root development which I usually do by this point. The cloning procedure was that I initially shaved a bit of outer tissue off the bottom half inch of the cuttings and dipped them in root tek cloning gel, and put them in the aero cloner with clonex solution at 700ppm. The cuttings’ stems were all thicker than usual due to them being taken from the tops of topped branches, instead of lower, slender branches.
