I used Pen's method with some Black Madeira cuttings started on January 18, and was happy to notice roots starting today, the 30th. 2 of the 3 have roots. I mixed the perlite and water, put a layer in the bottom of the plastic container, laid the 3 cuttings on top, and covered with another layer. I put the lid on, labeled it, and set it on top of my fridge. In the 12 days all I did was turn the container over a couple of times and opened it once to peek. I didn't add any water at all. My house stays between about 60-70 degrees this time of year. It's clean and easy, and I'll keep using this method. Thank you Pen!
