Having read through the post again, my growing techniques don't look much different to yours. The undrained container contains peat and grit. The container is translucent, almost clear, plastic so the underground portions of the plant are exposed to light around the outside, the exposed portions are green so maybe they photosynthesise? I water everyday which completely submerges the leaves but, due to evaporation, they become partially exposed before the next watering. It is next to a window which receives good light but no direct sun, there is also a suplimentary 70W metal halide light which is on for 14 hours/day but it covers a large area so intensity is quite low. It has now been flowering non-stop for several months.So....how did you make it flower
I think I've grown enough to carpet our living room, and not 1 little flower
Lovely pictures by the way.
Sorry if this is a stupid question, but what is grit?

Mobile,
Thanks for sharing your impressive results with this species.
Any idea what temps the plant sees in summer / winter? How long has it been growing undisturbed in the same pot?
Mine are deffinately not crowded so i don't think that is an issue. They have always reliably flowered during the Summer for me. So it seems pretty certain to me that it requires long days to flower. The question though is does it require a short photoperiod to prepare it for flowering during long days. I have also never had it flower underwater, It grows very well submerged but the flowers always come from the plant that is above water, while the water tray is filled with submerged plant and no flowers.
How long do you have the lights on?
