Nutrifield Jiffy Pots and Jiffy 7 are your 100% biodegradable rapid propagation growing medium. They are produced from Canadian Sphagnum Peat moss and wood pulp. Due to this composition they prevent root spiraling and binding, while promoting strong feeder roots. Every year our Jiffy 7 pellet is used to plant tens of thousands of trees, a statement that we are proud to make.
