Answer: These sun loving tropical plants can be difficult to overwinter indoors and it sounds like yours are suffering a bit already. They need full sun, warm temperatures, and plenty of nutrients to stay healthy. You might try running the lights for about 16 hours a day keeping the bulbs fairly close to the plants, and raising the temperature of the room to the mid seventies. Finally, these plants can be grown with their roots in a pot and the pot plunged in the water, thus allowing you to add fertilizer tablets to the potting soil.
