I've been growing miniature Orchids in a small terrarium for about a year, but I'm still in the dark when it comes to light. I rrad about the footcandles required by different genera, but I have no idea how to know how much my aquarium LEDs are putting out. Seasons. My understanding is that there isn't much difference between summer and winter in the tropics. Arenm't these short day plants? I'm willing to adjust the photoperiod during the year if I need to, but do I?
