Zygo potting medium

What media are people growing Zygonisia, Zygopetalum, etc. in? I have a Zga. Kuitpo Leopard that's outgrowing its pot at kind of a shocking rate -- a week ago, I didn't even notice a shoot and today there's a super fat growth over an inch long! It also abandoned a p-bulb in the past week and a half or so, so I assume it's essentially trying to move house. It looks like the grower has its roots wrapped around a block of floral foam (?) -- not really sure what it is, honestly. A little cube of. . . stuff.

I have a bark/charcoal/perlite mix and sphagnum here at home. Anything else I should get to give it a good repotting?

myself and a very good friend of mine who is a major breeder of Zygo's just use bark,with no additives.The grade of bark that we use is grade 3.Its a medium size.

I use the same I used for all my orchids; coconut husk chips, charcoal, and perlite.

Awesome -- that's easy. Thanks!

Hmm, good to know.

I think the same... zygos don´t like very moist mediums... I have problems with growing zogos they seem just so unpredictable to me...

right now mine is doing well in Sphag. it did not do well in semi-hydroponics and it has recovered in sphag

sphagnum? do you let it dry out completely??
