The Jiffy-7 peat pellet is made from sphagnum peat from specially selected peat bogs. Lime and a special fertilizer with a low ammonium content are added to the peat in order to stimulate growth. The peat pellets have a pH of approximately 5.3 and are wrapped in a thin, biodegradable net. Ideal for starting your seeds indoors! Just put a few seeds in each peat pellet and add water. Each pellet has its own compartment. All you have to do is put the dome lid on top and you have ideal temperature and climate settings to propagate your seedlings! The peat pellets expand into a self contained soil container held together thin netting. Drop the netted container directly into the ground or planter pot. No mess, no fuss. Jiffy peat pellets are the best and easiest way to start plants early.
