Need help want to grow inside!!

Hey guys, i have about 8 plants growing right now, there all about 6 - 8 inches high, pretty healthy. So i want to grow inside my friends room, his parents are cool with it. But i need to know what i need to get etc, i dont want to spend a lot of $$ i know i need a HPS light, so if you guys could help me out that would be awesome!!

I have 4 marijuana plants that were from some regular weed, and i have 4 that are super thai skunk seeds that i bought online.

So if you could help a brother out that would be great!! I'll take pics of the plants if you guys want me too .
