Biodegradable, eco-friendly, no transplant shock! An alternative to plastic and peat pots, CowPots are manure-fiber based pots. Invented by two Connecticut dairy farmers who were looking for an environmentally responsible way to dispose of cow manure. CowPots are odorless and free of weed seeds due to the composting process. Pots are 100% biodegradable and can be planted directly into the ground. They last for months in a greenhouse setting but quickly break down once planted, giving the young transplant valuable nutrients. Pots measure 3" across and 2-7/8" deep.
