you would need Pure Sphagnum PEat for soil, with either half perlite or half sand. Use only Pure WAter, and sence you just purchased it im guessig its kind of weak for a VFT, so i dont know that you want it going dormant it could die. So use artificial light I dont know to much on that but some one ealse should and will fill you in, but basicaly a couple Cool flourecent light bulbs, and a timer works good, they like lots of light, probably bout 12 or more hours of light to get good coloration. But being inside it wont get great coloration. As for puttingit inside, dont just take of the Plastic dome, slowly take it off, prop up one side a lil bit for 2 days the other side for 2 days so on and so forth till you prop all sides off, then you leave that their for about 3 days then take it off, this is what has worked for me. You would want about a 6 inch Pot. And would probably want to have about 2 inches in standing water letting the water table change from time to time, and its ok to flood it once or twice not to often.

Some one will fill you in more detailed if i missed any thing.
Cheers n good luck

To better know your plant, you have got to tell us how big is the plant, how many traps does it have? Is it red on the inside of the traps? Do you have a back yard or a place where the plant can take full sun? And what is the zone where you live?
