The first thing your gonna want to do is put it in a pot thats at least 12 inches is diameter and at least 10 inches deep, go to a nursery or plant type shop and get some potting mix (thats ya soil).
For optimal growth you should probly make some reflective housing for your plant, just get a big bit of flat cardboard big enough to rap around the plant (allowing for about about 2 inches from the edge of the pot), cover it in aluminum foil with the shiney side facing away from the cardboard and toward your plant. Best to make a lid using the cardboard and alfoil also. For a light just get your self one of those low wattage eco bulbs (easy on your wallet in the shop and on your bill, not to mention better for enviro) and have it sitting inside the reflective housing while making sure your not creating a fire hazzard, just turn the light off for 6 hours a day and your plant should go nicely. Make sure to water generously also!
Ive been growing for a while and ive found that this method wins on the cheapness to optimal growth ratio.
Peace!
