They've been in the same location (SW window area) since I've gotten them. Pretty significant temp differences between seasons since I don't have AC in the main areas of my home. Over the summer they were in very humid/warm conditions but since the seasons are changing it's now very dry and the temps hang around 68-70. About a week ago I noticed their jars are freezing so they've been on a seedling mat.

What is the
formula of the fertilizer and
how often are you watering with it?
Concerning the cold containers, LECA holds a lot of water and is still nice and open and airy. That allows the water to evaporate quickly, leading to evaporative cooling, especially in a dry environment. If you’re measuring 68-70, the roots are probably in the low 60’s.
As others have said, phalaenopsis are
hot growers; deep shade and approaching 100 degrees would be great.
