I have not propagated with one but someone has since companies already sell fertilizers for acid loving plants, including camellias, grown in aeroponic chambers; see the link below.

Here is a link that might be useful: Fertilizers for aeroponic chambers

Thanks a bunch Luis pr. I will put some in the propagator and let you know how it works. It is a little too early to cut them yet, but I have some that were given to me. I just have to try it. I appreciate the help. Linda
