Masdevallia deformis

This is not the easiest Masdevallia to keep going. I've found it does very well with cool nights: 50 F more or less in the winter. Daytime highs are usually mid 70's to low 80's in the summer, but sometimes spike higher. Moderately bright light seems a key for me to bloom it (didn't bloom for years once my fiberglass was old). But bright light can overheat the plant if you can't keep the temperatures down. I now grow it mounted (on cork or bark) with just a bit of moss at the base of the plant. Daily water with (drum roll, please) good quality water. Watch out for moss creep that starts to smother the plant.

Peter, I can't tell from the image, is it potted in the terra cotta pot or is a plastic pot the growing container? It is a great species, and I see you have more than one flower.

 

Peter, I too grow a lot of things (more and more as time goes by) in a net pot inside another, though usually plastic in my conditions, to give the roots that choice of in the medium or out in the humid air. I don't grow much in terra cotta, but was wondering if you would have more cooling at the roots if the moss was in contact with the clay to increase evaporation and therefore cooling.
