My father and, I back in the 70's, started a worm farm... Turns out that we were good at breeding worms but bad at marketing them... Back then we had eventually 50 4'X4' bins... Each bin back then was worth about $500.00 and carried about 2 to 3 hundred thousand worms... We drilled holes in the bottom of the bins for the water to drain out but we put them up on 4"X4"'s so the worms won't escape... The will hang out the drain hole but if they can't reach the ground they will go back in... For the top you just put news paper over it and they won't come out the top... So you throw in some cow manurer, a little news paper, water, and do it again in two months too split them again... FYI... you can't use horse manurer because people de-worm their horses... I'm going to give it a shot and I will let you all know how it turns out... :aok:
