Jiffy-7® Peat Pellets for biology and life science contains disc-shaped pellets that are made from compressed sphagnum peat moss surrounded by a plastic netting material.
Disc-shaped pellets are made from compressed sphagnum peat moss surrounded by a plastic netting material. When water is added, pellets expand up to seven times their original size—forming pot and medium in one tidy package. Developing roots easily penetrate pot exterior so that young plants can be transferred directly into garden or larger container with minimal disturbance.
