Devlsgro rooting method is the method I used last season and still do with some cuttings, but if you want to make some of your cutting stretch a little further this way works pretty good. I just take a single node cutting and lay it horizontaly just under soil line (preferably with bud sticking through soil line) I use promix hp soil, bottom heat with no thermostat, 32 ounce cups, 600 watt metal halide set for 14 hours on, 10 hours off, I mist top of soil once a day with a yard sprayer. I've had a few of my Black Madeira shoot out roots in three weeks with this method. My garage temperature fluctuates from 70 to 80 degrees, but they seem to like it more towards 80 degrees so next season I will probably add a wall mounted gas heater to my garage. One other thing worth noting, I think exposing the bud to light is part of the key to making the cutting start to wake up and to trigger root development.
