I'm just looking for the ideal medium.
I have seen Akadama but not in the size I want. While looking online, one vendor had a couple of heat treated ("hard" and "baked") kinds. I asked them for more info in the difference but only got what was on their website. So I thought I would ask here.
I've done OK with lava rocks and hate perlite(does anyone worry about silicosis?) almost as much as I hate sphag. I have some plants in 100% Hydroton but am either trying to keep the plants from shifting or chasing after the rolling balls!
Akadama looked more porous than hydroton, less porous than lava rocks and harder than hort pumice, I thought it might meet most orchid needs. I really want to get rid of the 3 crates of different media I have.
That online vendor's shipping cost makes them prohibitive to order from. I'll have to keep my eyes open for potential bonsai supply places.
Edit to add: I have one NoID catt in all hydroton and no phals.
