Vermicomposting, worm bin, composting with worms community and forums
My wife and I were just discussing that to date we've given away and sold a total of 5 lbs to friends and new friends (previous strangers). The sales have given us a chance to basically recoup our initial investment in the hobby.
I sold 1/2 lb for $17 to a few and 1 lb for $26 to some others. I'm out of worms right now except for about 3 lbs of my personal supply and I actually have a "waiting list" of people who want to buy them. Pretty cool.
My dream is to sell in commercial volumes eventually, but I don't have land available to make that happen.
