These Jiffy Grow Blocks
are an innovative new growing medium which are 100% peat free, being made from 100% coco substrate. This mixture of coconut pith and husk chips are enclosed in a degradable netting making the Growblock
self supporting without the need for a plastic pot.
The purified, stabilized coco substrate is carefully manufactured by Jiffy
to have a water holding capacity of 60-75% and an air porosity value of 20-35%, this tried and tested construction ensures optimum oygen diffusion along with ideal water holding which results in rapid, stronger rooting and very healthy vegetative growth on developing plants.
