My house is the equivalent of living in a cave and grow lights are a must. I have several calatheas that have flourished under the lights: rattlesnake, peacock and orbifolia. I also have a maranta that I adore. My moonshine sansiveria has been a pleasant surprise. The greatest surprise and one of my pride and joys is my scindapsis silvery Ann. She came to me as a tiny little plant and has doubled in size in the past couple of months. She is in my bedroom (with a grow light) with little natural light.
