For now I grow pumpkin, tomato and peppers. Participate in a small pasture run egg operation, but am getting geared up for heirloom seed production. I have always supported myself through agriculture. The most exotic was shiitake mushroom (also the most lazy), the most exciting was cut flowers, but around 2003 the economy tanked in my area and the flowers quit paying the bills.
I'm still trying to get my button mushrooms to grow, and haven't tried any of the exotics until I get that down. Being a former cook, I do like to have good and fresh foods to work with, and the more of it I can grow myself, the happier I am.
