best advice i could give you is that if you're having a hard time scraping money together, don't grow... YET. take the time to save and use this time to READ THESE FORUMS AS MUCH AS POSSIBLE. there's a wealth of information on here that could get anyone with patience and the ability to read to a level to grow decent marijuana.

that said, if you do decide to keep at it... definitely pick up some CFLs with 5000k or higher kelvin rating, like everyone else said. i'd try to get you to switch to hydroponics, but you might wanna get your feet wet with soil first. i claim sheer luck that my first indoor grow (hydro) was a success. almost everyone says "start in soil, then when you're good at it, go hydro."
