Thanks to everyone for their advice! Hearing that someone had a leafless tree for 2 months that survived gives me hope yet! I haven't unpotted it to check the roots, I just don't feel like it would survive that kind of trauma. I've cut back on the watering and placed it inside a covered (empty) fishtank to preserve the humidity. I've turned the fish tank light on for the meantime, but I will definately invest in some grow lights. Thanks again Kim
