Name: Big Bill Livonia Michigan (Zone 6a) If you need to relax, grow plants!!
I have.
I tried many different medias in my 45 years of orchids.
Bark
Sphagnum
Cork nuggets
Wine corks
Chopped tires
Stalite
Pea gravel
Aliflor
Sponge rock
Osmunda
Charcoal
Tree fern
Orchiata
I have used them individually or in mixes. In Florida it was aliflor/charcoal/sponge rock because in that environment bark broke down in 6-9 months making repotting mandatory!
On Long Island and Michigan it has been bark mixes.
