My setup for growing these plants during the winter. I use an energy-efficient fluorescent bulb to provide light to the plant. It is equivalent to 100W but only uses 18W or so. I have the light on a timer set to give short-day photoperiod, which induces flower production in Ipomoea nil. I have it set to be on for 11 hours a day.
