I used to have a hard time cloning too. I tried everything, but the easiest and most reliable method is this.... I take my cuttings with a flamed razor blade with the blade at an angle, I dip the cutting in root gel, I plant the cutting in some FF light warrior with a little moisture. Mist for first 5-7 days. I usually use clear plastic cups. When i see roots through the sides of the cups, I repot. No humidity dome needed. 100 percent success this way.
