I have gotten to where I take the cuttings into a greenhouse (really a hothouse if there ever was one) where I have fans running 24/7 (I'm curing my garlic there). I might leave those cuttings for only 24 hrs. but more likely for 48 hrs., and then into the perlite they go. Five years ago I would never have done this. I let my cuttings callous for the prescribed one week (minimum) and usually that would be two weeks. I seem to get faster rooting by getting the cuttings into the perlite more quickly. It may be my imagination.
