I also just started a new, rootball recycling setup. I've got a 22 gallon tote filled with rootballs. I dumped about a gallon of worm castings in, along with about 1000 worms. I added some veggie and watermelon scraps and shredded, used paper towels. with my 2 worm farm bins, I estimated I have about 10,000 worms. going to start selling some on ebay next month. Think I'm going to 50 gallon totes soon!
