Hi tarev, we got the plant early July of last year. From July to September it stayed in the NW facing window (our home sits on a street that runs NE/SW). During that time the leaves, from the bottom up, turned brown and fell off. That's when I put the lamp on it to attempt to give it more light. Outside I have a spot picked in the backyard that is getting a little afternoon light. It's even on our patio, so we can still enjoy it!
Now I just need a replacement plant in the living room that will tolerate the lack of light.
