This is always my favorite part of the grow. I'm trying something new here. I used a 5-gallon styrofoam container and poked a couple of holes in the bottom. My antique GE fan keeps the air moving. I placed foam board on top of the soil to reflect light back up and keep my worms from getting sunburned. the only thing I've added is 1/2 tsp of TSP for Phosphorus. Once she leaves the inner pot, I'll give her a little dried chicken poop.
