Reduce feeding to mother plant in the days leading up to taking cuts. Cuts full of nutrients have no need to grow roots right away.
Make sure the mother plant is well hydrated before taking cuts(soil growers)
Start aero-cloner the day before taking cuttings. Use plain tap water, and add H2O2. Let run for a couple hours, then ph at 5.9-6.0. The next day, double check ph. I don't check PH again.
Take cuts with at least 7 nodes, and about an inch of stem below the bottom node. Place all cuts in water as soon as cut. Once you have all cuts in water, its time to get them ready for the cloner. Cut the leaves off of the bottom 2 nodes. Scrape the bottom 1" of the stem with your pruners, just scraping off the "skin" exposing the inside of the stem. Cut the tips off of remaining fan leaves(approximately 50%) to reduce the amount of water transpired. Dip in clonex, place in collar, and in aero-cloner. Place aero-cloner under weak light.
I leave them alone for 7-10 days and roots show up, as soon as they get hungry. They will yellow a little bit, and start producing roots looking for food. Temps are around 70 and RH around 30%. I don't use a dome and haven't had a problem yet.
Definitely not an expert, and this probably won't help most of you, but should help some newbs.
I was thinking about taking some pics when my HB Ghost OG Bastards are ready to be cloned.
