wowzers ! I believe I just went quackers for that green house. I have never seen moss grow on the outside of a terracotta pots before. That is insane. And like Exo, I have to know what that crazy green stuff that seems to be taking over is.
Your greenhouse is beautiful and very well organized; everything in its place! I noticed that even you neps are in trays; how often do you water them? Do you let them dry out in between waterings?
Wow! Great setup! Is that a female N. veitchii flower I see?
Is that a fusca from Sarawak?
