Maybe try one as mentioned above. That way you can expand your orchid knowledge at the same time!
I'd weigh your thoughts too on why else you might want to switch. For me, I'm not wrapped up in the actual method, but more wanted to reduce the bark repotting waste I was creating by repotting everyone once a year. Since I kept my orchids in saucers full of water all the time anyhow, their bark mixes broke down so quickly. I was spending a small fortune on bark every 6months to a year to repot everyone.
Plus, LECA is nice since we are helping to save trees.
read up, read more, and then try it on one if you'd like to experiment. Maybe you have a plant that wouldn't upset you too badly if it "pouted and sulked" for awhile?
G'luck!
