Hi all--I'm from Los Angeles, I've had a small collection of orchids (mostly Cattleyas & their relatives) under shade cloth in my back yard for years. They were suffering pretty badly in the heat & low humidity, so last fall I built a DIY mini-greenhouse for them. Now they're doing a little better, but not exactly thriving. Hoping to get some advice here on how to improve growing conditions in general and make them happier. Where would be the best place to start a thread about this topic, Growing Areas or Orchid Culture? I feel like my situation sorta overlaps both subjects.
