Thanks guys! I am going to buy a supplemental plant light. My boyfriends mom has one that is purely indoors and has grown HUGE. She has had it for years. My best friend also has one; his is little but has had a ton of blooms and lemons! Hopefully with more light and heat it will do better, my room can get a little cold from the A/C. Next month I move into my dorm and there is no A/C, so my lemon tree should love it! (Unlike me.) haha
