I just verified that the lights actually run 10.5 hours year round, not 12 hours like I first said.
In the natural environment, besseae, at about 6 degrees S latitude, has days ranging from only 11.7 to 12.3 hours. That suggests that day length is not much of a signal for plant growth or reproduction phases. Although 10.5 hours is more than an hour shorter than besseae's shortest day, giving enough light intensity can provide the total number of photons the plant needs, even in 10.5 hours. They could then grow and bloom well, as you have shown. Phrag. lindleyanum var. sargentianum in Jason Fischer comes from about 8 degrees S latitude, so a day length varies from 11.5 to 12.5 hours. Can you quantify the light intensity you give your plants?
