very nice , do you have them on a misting system?
and what are the light photoperiods?
vraev, The plant is actually growing in a pot and it sits in that fake rock.
The live Sphagnum just took over and covers the top so you don't see the pot.
I grow them in my basement on racks with T-5 lights. Some plants I have growing in an in-closed terrarium that does have a mister, but they seem to do fine down there just on the shelves.
