Phalaenopsis bud drop
I have a problem perplexing me. I've grown orchids for over 20 years and Phals have always been a problem for me. In this case, I am growing some phals in my bathroom under grow lights. I have one NOID phal I bought a year ago while it was in bloom and bud, had no issues with it. It had one flower spike. This year it grew two spikes, and every bud blasted as they grew. I have another orchid I just received by mail order about two months ago and it had two spikes on it. All of those buds dropped except for one, which bloomed. To confuse things, I have a third phal I bought at the grocery store about a month ago, in bloom and bud, and it has been totally fine, all the buds are blooming, none have dropped. The bathroom is small and stays a pretty constant temperature, but the heat vent is across from them, maybe 6 ft. away. I don't physically feel the air coming out of the vent and blowing on me when I'm in there. I can't figure this one out.
