Hello
These are biochemical processes within the Corm, which determine whether a plant flowers or not.
Konjac is not temperature or light dependent.
This is done all in the resting phase and since the tubers from Earth are covered. So there may have been times to do not with the light
I think me to remember that it is still not properly understood, what the plant to the blossom brings.
In konjak, you need do nothing special.
Only the bulb must have reached the flowering size. The rest goes to the resting phase of all by themselves.
If you see that the shoot from the Corm is growing and growing, without thereby making roots, there is a flower. Then you need to pot the bulb does not. Are Yes trockenblüher. Easy then put the bulb in a warm and bright place and wait. Only if the flower has died down and the tuber is roots, off into the Earth.
Hope I have helped.
MfG
