Many phalaenopsis and most Maudiae type paphs will bloom without a day/night differential. That's a start. I would agree that they probably bloom better and more frequently if given the proper diurnal range. I think this came up a while ago on another topic, but I will paraphrase - many modern hybrids have had 'stupid' bred into them - at least when it comes to responding to their normal environmental cues. All that said, I don't know of many environments where there isn't some sort of diurnal change in temperatures. Even in a house it is usually a little cooler at night. It may not be 10 degrees cooler though. Rob -- Rob's Rules: http://www.msu.edu/~halgren 1) There is always room for one more orchid 2) There is always room for two more orchids 2a. See rule 1 3) When one has insufficient credit to purchase more orchids, obtain more credit LittlefrogFarm is open - e-mail me for a list ) Thanks Rob. K |
