Organic Fruits And Vegetable Backyard Sellers?

Any TVer's or know anyone in the bangkok or surrounding provinces that grow organic, non pesticide non hormones non anti biotic using farmer that I an purchase vegetables and fruits from?

I'm sure some of them may have surplus yields they can sell on the side.

Or would it be easier to buy form local organic supermarket? I only know of Lemon farm and Japanese FUGI markets that have good quality stuff. Any other stores?
