Does anyone have a DIY intermittent misting system design that you want to share for plant propagation? I'm interested in rooting cuttings on a small scale, with the long term goal of scaling up to something bigger. I've found timers online for as low as $40-$50, and the rest seems pretty simple. But if ya'll have designs to share, it would help me to confirm whether I'm oversimplifying.
I set up a very small one by using an ultrasonic humidifier on a regular Walmart timer. It works great for small scale. I used plastic tubing (1" I think it was), made a hole in the humidifier output cover and piped the other end into a plastic tub I got at Walmart. I melted a hole in the tub and pushed the tubing into it.

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.
Story like this gets better after being told a few times. Or maybe it's just a tiny ad:
