Years ago when I was starting lots of
rose cuttings I set up an extremely primitive misting system. It was just a hose-end turn on/off, very inexpensive thing that I adjusted to a very fine spray. I had a 'table' on a slant, and it was covered with plastic sheeting that directed
water into a container with hose attachment that let extra water, gravity fed, into a small
pond.
I left the mist on during daylight hours, and off at night. The medium I used drained very well. The cutting leaves were always wet, but did not rot. Several people said to keep things this wet/damp would not work. But it did.
I do live in a very dry environment, and roses are plants that are perhaps less prone to water damage. But I got well-rooted cuttings with no problems. A species that might be more oriented to dry environments might not be as successful.
