Corky, its not just photoperiod but seasonal temps that trigger gemmae.. They need to feel the range of seasons to be triggered usually.. For instance, in my set up and apartment, summer gets pretty dang hot.. The pygmies prolly get to 90ish during the hottest part of the summer, then as our weather cools down, so does the average ambient temp. I keep the plant room window cracked, even at night, so the night time temp drops as well.. Into the upper 50s usually right now. And they're all producing gemmae like crazy, even though I havent adjusted my light cycle to winter mode.
