Jiffy pots are manufactured from a minimum of 50% sphagnum peat, wood fibre & lime (to regulate pH levels). The peat content gives optimal soil porosity and improved root penetration whilst the wood fibre gives the pot structural strength.
Benefits :
Air pruning gives strong, fibrous root development
Minimal root disturbance & reduced transplant shock on potting-on
100% biodegradable product means no de-potting & waste packaging generation
Root zone microclimate averages 1 degree higher than using plastic pots
Buffering capacity of pot reduces water consumption by approx 20% compared to plastics
Peat-free (coir) options available - Coir is easier for roots to penetrate so is recommended for use with bedding & other short-term crops
NOTE: All pots have drainage slits except J8PF (peat free)
