Learn About the Urban Worm Bag
The Urban Worm Bag is a fabric continuous flow through worm bin that promotes aerobic conditions and allows for an easy harvest of worm castings.
As worms tend to move upwards into layers of food above, the rich, lively castings are left behind, meaning that the bottom harvest is almost 100% worm castings.
What Makes It Different?
The Urban Worm Bag is 3x larger than the Worm Factory 360 and only 33% of the price of the Hungry Bin.
Version 2 now comes with an interior fabric enclosure that protects the zipper as well as a sturdier frame than Version 1.
