BTW, had a greenhouse and it was a pain! Lots of work! If your current setup works, go with it! JMO.
I also hope you win the calendar 'cause I'd hate to have you sit and gawk at kids in 'cinis

I don't do most Dendros or large, "floofy orchids". For me it's minis (like Angraecoides), Masdies, Paphs, and others that crept in somewhere along the line. See my orchid list for complete collection (usually not current.)
