Welcome, and thanks for the pictures. I love tolumnias and have only recently added some pleurothallids to my collection. I don't have 350 plants, but I'll catch up some day. I hope to see a lot more of your pictures.
WOW ! 350 orchids is not small! I have maybe less than a hundred orchids LOLZ...and I consider it plenty because I am a windowsill grower...
