No success with roottech. I switched to sticking cuttings into a plain glass of water and leaving it there for days. Then, when the stems look warty, I stick in coco plugs. I've had a 100% success rate this way. Today, I bought some clonex gel. I have 5 cuttings dipped in clonex, stuck 'em in coco plugs, and put under a humidity dome... we'll see how that goes. But, 100% success rate using nothing. Be careful if using a humidity dome. It's beneficial at first, but after a few days, it's the quickest way to rot your cuttings.
