Thats a tight budget unless you want to use a bunch of CFL's, which i wouldnt recommend. Save up for some sort of HPS light, if you can afford a 400w you'd be set, probably 100-150 max. The light is the most important part, save up and do it right
Agree with the HPS. If you are going to start this as a hobby then go HPS because you go CFL initially you will likely switch to HPS for the better results so why not start out right. I started off CFL and switched during my first grow. I spent alot on CFLs and regretted it in the end because I Wasted money on the CFLs thinking I was going to be able to grow dank thick buds for cheap.
