What I need to be happy in your home:
Light: Rhaphidophora tetrasperma requires bright, filtered light. Indoors, direct sun is fine; outdoors, a little bit of dappled sun is fine as well. R. tetrasperma is decidedly NOT a low light plant - it will grow slowly and will produce small foliage if placed in an area with too little light.
Water: Rhaphidophora tetrasperma likes to stay pretty moist, at least during growing season. Water when the potting medium is dried down 1-2" and don't let the root ball dry out. In the winter, you can cut down watering.
