Who is Urban Worm?
Did you know?In a continuous-flow worm composter like the WORMbag, the worms move up on their own toward fresh food, so you can harvest the vermicompost at the bottom without disturbing them.
Urban Worm (Urban Worm Company) is based in Plymouth Meeting, Pennsylvania. Urban Worm describes itself as "an education company first, an online store second": the brand shares a wealth of guides to help people learn vermicomposting.
Urban Worm's WORMbag is a continuous-flow worm composter made from breathable technical fabric and mounted on a lightweight frame, with no tools or glue required. The bottom of the WORMbag opens so you can harvest the finished vermicompost while the worms keep working above.
At Moutta Farm, we chose Urban Worm to offer a large, easy-to-use continuous-flow worm bin. The WORMbag joins our lineup of continuous-flow worm composters. The WORMbag comes with a 2-year warranty.
