Id look on ebay for a kit already made. I would say to go for a Deep Water Culture system. Their not too complex. Now for the nutes, I use Advanced Nutrients Sensi A&B Veg and Bloom series... pretty good stuff but kinda pricey, like 35 bucks for the A&B together (1qt) But my second choice would be Fox Farms. And if your doing the DWC, you can do good with General Hydroponics nutes, their cheaper priced, but not good for misters or water pumps. Working with a budget for lights, I would go buy some Compact Fluorescent Lights CFL's with 6500k output and 2100k output. The more watts the better of course, aim for at least 23w. You should get all you need and pocket a good amount too, maybe to buy a sack of some dank and use them seeds... just a thought
