I haven't had it long enough to be mineral build up and it's fluffy and fuzzy. Also, if you looked at it from the side, it was raised, not like a mineral spot that has seeped into the pores of the pot.

The mould has spores that can get around. The spores are probably in the air all the time, and everywhere.
Have you got mancozeb? Dry the top portion out a little bit - then could probably spray some mancozeb on the roots and media surface.

Maybe the plants do well like that. But - I genuinely can say that paphs and phrags etc can handle being a bit try temporarily too. I know this, as I grow them all in scoria. Semi-outdoors --- under a balcony, in a tropical climate, good amount of light. Air movement - usually gentle and quite satisfactory. Sometimes even a bit breezy. I've never seen mould on the roots or media surface.

I will buy a fan and put it inside the greenhouse. Maybe that will help. I have also considered going s/h with LECA rock, I have the LECA but I am still doing my research to make sure I do it correctly. Also, I will go longer between watering. I don't have mancozeb, but I saw a youtube video that said to wpie the pots down with neem oil and I tried that. But since I switched to a plastic pot, I guess I won't know how that works unless I have problems with a different plant.
