Ursula, If I had your set up I would! So far, I have had good luck with buying from reputable vendors and buying small plants in bloom. I also try to avoid plants that aren't "temp. tolerant", or that need very high humidity. I also try to buy from local growers, if possible, another reason I haven't bought from SBOE. They claim to grow their Cats and Dens outside, year round. They are a block from the ocean...I'm 10 miles inland. Lot of difference in climate! Andy's and Sunset Valley are an hour south of me and about the same distance from the ocean as I am.
I didn't have time for orchids until I retired a year and a half ago. Now I have nothing but time, so I can baby them along.
