    Thanks for sharing a great pic of a bunch of flowers. It's hard not to be impressed when they throw out some blooms.

    Mine never flowered under lights for me (even when I manually adjusted the time). I did some research & found that many people who grew them on windowsills got blooms. About 4 years ago, I stuck some on the windowsill and have had flowers every spring (which can last for months if you don't pollinate). I'm not sure whether it's the seasonal photoperiod or the temp change (gets cold against the glass in the winter) or a combination (....or something else). I just know it's nice getting those flowers ...
    All the best,

    I suspect that it's temperature, as mine grows under metal halide lighting year round, with no change in photoperiod. It gets some incidental natural light, but I don't think it would be enough to influence it.

    I know this is an old thread, so apologies, but I did want to throw in some observations that might explain your flowering. For years I'd grown some terrestrial broms and numerous succulents under lights without adjusting photoperiod. Most of the plants still exhibited some seasonality to their growth. Temps might be involved, but I think the real cause is far red wavelengths. Far red light can travel quite some distance, and bounces around rooms fairly well - if you have any windows to speak of, I suspect enough far red lights gets in to trigger flowering.

    Yes, that could explain it. I've been reading about far-red light recently. In fact, I've recently purchased an LED lamp containing far-red.

    Could explain why mine has suddenly decided to flower for me now, after 2 years of sulking....
    Everything has a reason, whether big or small. Never underestimate the power of what is or is not.
    There is far more to everything than meets the eye.
