I grow 500 plants and 150 species in a 9 x 12 x 9 greenhouse at my home in Napa and a second 12 x 25 greenhouse in Sonoma.
I am on a budget. I try to add to my collection in the most economical fashion possible. Hence my interest in backbulbs. I have more time than money, therefore I am willing to invest two or three years in a new species. I study orchids so I'll know where each of my orchids grow in nature.
I don't claim to be an authority on orchids. Take what you like and leave the rest. I will tell you what I did and if that helps you at all, that's great.
