Two phalaenopsis different outcome

[aliceinwl]

Most of mine are on window sills. Both my home and office where I have them are heated and the Phals still spike. I’d give time a try and then lighting. I do have one long term Phal that hasn’t rebloomed for me. I moved it to a brighter location last spring and I’ll see if that does the trick this year. If it doesn’t, I’ll probably put it outside for a couple of weeks next fall to experience colder temperatures. If yours don’t bloom for you this year, maybe you could try cracking the window for a few weeks next fall after temperatures drop but before they get really frigid?

I think a few of us are in the same position as you, Irisha, as far as indoor temps, where we have a central heating system with an automatic thermostat, and if we open windows, then the heat just kicks on. Yes, we can turn the thermostat down, but then the whole house gets colder. That's fine if one doesn't mind (but I can't stand being cold at night). If one has a room or part of our house where the door can be closed and heat ducts can be closed off, that would be fine, but if not, opening a window is just going to produce higher heating bills.

Experiment with light levels, more or less than what they're used to. Experiment with watering more or less. Just try different things. I've got a couple of non-blooming Phals right now that I'm doing that with. Let us know if you find the trick.
