Hi all, forum newbie but have had orchids for about 20 years. I have a bunch on a bay window sill (phal, dendrobium, oncidium, potinara, ascocentrum, brassia...) and just bought a string of little solar night-lights which I put above the window; they're 2-3 feet above the plants. They aren't terribly bright lights, but I wondered if they would be enough to bother blooming cycles. Most of the orchids are doing pretty well there, and I realized I don't know if they require a certain amount of dark hours to bloom. There has been a single small night-light to the side of the window for some time. I think it's brighter than the solar string. Any ideas? Thanks!
