Thank you so much for the detailed response! I currently grow on south-facing windows, but I’m considering adding some supplemental lights since I’m pretty much out of space, and I’d like to try to bloom them closer to their full potential. The days get pretty short up here in New England this time of year. Your setup seems to be working great!
I get decent temperature drops at night from fall-spring, particularly near my old, drafty windows, but struggle to get much of a differential during the summer. So far it seems to be ok- since most of my plants are fall/winter bloomers, they’re usually finishing up their last growth just as the temperatures start to dip. It’s reassuring though that you’re getting such great blooms without getting down to 62.
If I’m not mistaken, it looks like you have another sheath there on the Betty Ford, so hopefully you’ll get another wave of blooms soon!
