You need a much better setup. You say your broke but jsut got a job so youll want to do this as cheap as possible. The thing about growing is you can't cheap out and hope for best, you need to think out every detail and spend some scrilla, Don't cheap out on lights and soil and that stuff. Anyway heres what you need to do:
1---Buy a HIGHTIMES. Or some weed magazine, learn some shit.
2---Hit up google, type in rubbermaid grow box, learn some more shit. This is probably most effective, cheap grow setup I have read about.
3---Throw that stringbean out. You can use 2 13W CFL's for seedlings, That's it. After a week or two you will need to step it up to a good 3000 lumens. and youll have to reduce some lumens for light spillage, not every beam of light is hitting the plants.
