Get healthier, livelier plants with Worm Power! These easy to use reusable brew bags allow you to brew your own worm compost tea using Worm Power or other compost material. Made from food grade cotton bags made here in the USA, each bag measures 3 x 5" and has a double draw string to quickly tie off your bag. Place worm casting filled bags in non-chlorinated water for 24-48 hours, stirring occasionally. Use 1/2 cup of Worm Power material per gallon of water.
