Small wafers of compressed peat encased in a plastic net. When water is applied, the Jiffy 7 expands to form a soft pellet about 4.3 cm (1-3/4″) in diameter and about 5.3 cm (2-1/8″) deep. Seeds or transplants may be directly sown into the pre-drilled hole in centre of pellet. When rooting cuttings, the centre of the swollen Jiffy 7 can be hollowed out to the required depth with a pencil, the cutting can then be inserted. Finish by gently squeezing the Jiffy 7 around the stem of the cutting.
