    Has anyone had experience in growing Restrepias on inorganic materials? Do they do well?

    Examples of materials: Epiweb, rock wool slab, foam
    I was thinking of trying one on Epiweb.

    Mostly, I've seen restrepias on trees, but one often sees stelis species growing on boulders, fence posts, wires (power/communication/fence), and so on.

    You can grow them on just about anything you want as long as it isn't phytotoxic AND you manage their water and humidity needs properly. You can tie them to a string and keep 'em growing if you manage their needs properly. Keep in mind that if they are on any non-porous substrate, your "success window" becomes smaller. Even more so if that surface is smooth

    The whole point of choosing a substrate is to enlarge that success window, given constraints on substrate longevity and appearance.

    How can one test phytotoxic in a material?

    Technically, those are organic.

    So phytotoxics are only present in organic materials and things that are coated in chemicals?

    No. Some rocks are phytotoxic, for example things high in selenium. Also, some rocks can be quite alkaline, and roots might not be too fond of that.

    Basically, you need knowledge guided by experience. You need to know the composition of the material, and the experience to tell you if it will be a problem in your conditions.

    And by the way, EVERYTHING is a chemical. Water is a chemical. Air is a mixture of chemicals. Don't wander off into the weeds of ignorance thinking chemicals are nasty, evil things that will only cause harm.

    I'm trying them in pots with expanded clay pellets with a programmable sprinkling system and nutrient proportioner. The jury is still out but they made it through a hot, dry summer already. I'll report in again if/when they bloom.
    Jai, you can try looking up the manufacturer of the powder coating to see if it is non-toxic. Many are because they are used for parrot and pet enclosures.
