All-natural Jiffy-Pots® and Pellets® are made of 100% biodegradable Sphagnum peat moss and wood pulp. The pellets also contain a minor fertilizer charge plus lime to correct the acid pH of peat moss. Reduce transplant shock with Jiffy-Pots® and Jiffy-7 Peat Pellets. Roots do not spiral inside the pot as with rigid containers, but naturally prune themselves as they come in contact with air. The Jiffy Professional Greenhouse 72 contains 72 Jiffy-7 Pellets® compactly packaged in a reusable domed tray.
