    I had a tendency to underwater before, both out of habit from growing epiphytes and also because bark and other organics turn into goop very quickly in our summer heat. Now that I've switched over to inorganics I water 3-5√ó weekly depending on weather. The rockwool holds enough moisture that I could probably get away with less, but it is airy enough that I'm not afraid to keep the plants wetter than I used to be able to and they seem to prefer it.

    Yes, you are right. Only one type seems to be available. And these appear to be hydrophilic as after a week they are just beginning to dry on top. This could be a problem.

    Maybe a problem for things that want to dry out like Cattleya, but not for moisture lovers. I have Paphs, Phrags, Brassia, Phals, and Catasetum alliance plants all thriving in it, as well as some non-orchids like Hoya and epiphytic cacti.

    What do you mix with it and what percentage?

    Perlite or LECA depending on pot size, roughly 50/50.

    All of my slippers are in S/H culture with LECA.

    Interesting discution! Have you compared shreded synthetic foam like the one used in cushion with rockwood? What is exactly LECA and is this material available in Europa. If not is it existing an equivalent in Europa?

    LECA is Lightweight Expanded Clay Aggregate, and it was developed in Europe for use as an aggregate in lightweight concrete, allowing concrete building to be constructed taller. It was later co-opted for hydroponic growing.

    Atami's B'cuzz Hydro-Rokz is probably the best one out there, as it was reengineered specifically with hydroponics in mind.

    Is Atamai available in the US? It appears to be only Europe? https://www.atami.com/en_gb/hydro-rokz-8-16-mm

    Do you get it from CA?

    I don't get it at all, any longer. I just use Hydroton from my nearest shop.

    Before ATAMI sold the Hydro-Rokz brand, they repackaged it for me under the "PrimeAgra" name. Back then I imported 40' containers of it periodically from Europe, but later they had an agent in Canada that maintained inventory, so I cut back to buying a few pallets at a time from them.

    A few years later, Atami set up an agency in the Caribbean somewhere, so I did business with them, but they have not been particularly aggressive about marketing the stuff in the US, so it's really hard to find.

    You know of a vendor in US where you can buy smaller quantities?
