I was in the process of building a media free plant support for the aeroflo units you would be able to use them in custom units as well. I was wondering if there would be a market to sell them? If I get enough feed back for them I may produce them. I would need to know what people would be willing to pay per unit. I have to build the mold, and produce 200 which I plan on doing for myself any way. If I get enough interest I will post pictures of a prototype built from separate pieces glued together the final unit would be a one piece housing with a insert to hold the stem, and an external hole that could hold a support stick.
