I'm a Scorpio who has been infected with orchid rapture for for lo' these many decades.
I have a mixed collection mostly growing under lights. My plants always vacation outdoors from late May till chance of frost. This helps to separate the weak from the strong. Orchids can be quite tough if met half-way.
I will try to impart what I have learned, the good and the bad. Don't be shy to correct me if I'm off base. I learn all the time from this obsession.
