Well I do agree. But in spite of my experience, I consider myself to only be a fair Cattleya grower. I think prior to my retirement, I did not pay enough attention to many of my plants.
But retirement frees up time for most people. In Florida and underlights, I SEE so much more then ever before. Plus I maintain a more regular watering schedule. I think that a proper watering schedule is so important, more so then I ever imagined.
I have one good, south facing windowsill in my home and my "reaquisition list" has bowringiana, skinneri, George King, and Goldenzelle on it. There is no height limit to meet.
Maybe that is the key to good growing. You must learn to recognize what conditions you can provide and buy only what you know you can grow.
