I was just looking at that today, I searched on "cloner" and came up with several threads about these machines and homemade ones.

This is the one I think I might want, a little more expensive, but can handle a lot more cuttings.

Several threads I came up with describe one you can make yourself and how to use it. I'd like to know a few more details, said a bucket with a cover, but I would think it would have to be a clear cover.

Not a whole lot about cloning roses using this method, but somebody described all the things he had cloned with his setup, including tomatoes in about 3 days.

In the meantime, I'm doing an experiment with a couple Dr. Huey cuttings and the Walmart aquarium bubbler you buy the components and put them together, too soon to know if it is going to work.
