Yes, my thought was long day vs short day bloomers. Short day bloomers bloom in the fall when the night starts to lengthen. Long day bloomers bloom in the spring when the night is shortest. You can intentionally (or unintentionally) manipulate that with lights.
My grow lights are timed to sunrise and sunset so about once a month, I reset the timers. That allows my plants to bloom when they are supposed to bloom. But, if the lights were the only source of sunlight, I could change the length of my days and make my plants bloom out of season. Likewise, by having a plant that is very sensitive to long day/short day in a spot where the lights were turned on and off, it might never bloom. It's not the day length that triggers blooming cycles but rather the night length. If you turn on the lights, the plant's internal clock resets and starts counting all over again.
