Do you have any supplies right now? How old are you? Well try going to some construction sights in your areas, places where they are remoddling or demolitioning a building and allot of times the workers will give you the old lights that are going to be tossed. You can sometimes get HID's and allot, well most of the time T12 bulbs and fixtures.
If you are not in your own home and still live at home you may want to read the FAQ about growing in your parents home. No offence if you dont, just never know.
