I stopped using a dome years ago. Domes increased my time of rooting, chance for disease, and on top of that more maintenance for me. No dome has been like set it and forget it, I get roots in less than 5 days most of the time too w/o a shred of maintenance. Cloning has been around a long time, I wonder if they used domes in those old days?
I like to share info I never tell ppl to do as I do, what works best for me might not work so well for your plants.... always do what works best for you and your skill level.... I'd try to do a few this way while cloning your regular way till you get the feel.
