Mango Plant

About 6 months ago, I cleaned a mango, that I had recently bought at a local grocery.  I let it set for a few days, and then cut it open, cleaned the meat and peel from the seed, and placed it on the window seal, to dry.  About a week later, I noticed a place on the side of the seed that had popped open, from drying.  I removed the inside from the dry hard outer shell.
I took the inside seed, and place it in some water, which I changed daily for about 4 days.  By that time it had started to grow a small root from the sloped end.  After another week, I removed it from the water and placed in in the pot here in the picture in some potting soil.  Covering only the root portion and loosely covering part of the rest of the seed, leaving most of it exposed. 
Here, you see my plant growing and now, I will need to keep it in a warm bright area.
