You got to meet growers man. The best way to meet growers is to grow yourself. I know it sounds silly, but that's how I met all of my growing friends and "gurus." It could be at the local organics/hydro store or it could be at a lumber yard. People are lot more likely to trust you when whip out a jar of your homegrown to share then if you just walk around asking for work. If you catch my drift.
