3" Round CowPots Greenhouse It has a 1/2″ femaleDescription Specs FAQs CowPots are a biodegradable planting pot made from composted cow manure. Your plants will love these pots! CowPots were created by a group of dairy farming brothers in Connecticut. Since 1997, they are one of only a few farms across the United States to have continuously run a methane digester. This is a process in which the raw manure from the cows is heated and stored in a large tank. The methane gas is collected and burned.
