The Jiffy Growblock contains 100% RHP Certified coco substrate and is delivered as a dry plate enclosed in netting. This is highly efficient for both transportation and storage. When water is added, the plate swells into a block or slab, ready to propagate or cultivate your plants and contained by the netting to keep the medium together and the greenhouse clean. Growblocks can be ordered in a wide range of sizes, with or without seedling holes depending on your specific needs.
•Higher yield
•Stronger plants
•Time and labor saving
The purified, stabilized coco substrate is carefully selected at our own Jiffy production site to give a maximum Water Holding Capacity of 60-75%. Air-filled porosity of 20-35% ensures optimum oxygen diffusion rates in the root zone. The production process of the Jiffy Growblock allows growers to adapt any fertilizer application with a range of EC and pH levels. Coco substrate is a renewable, environmentally-friendly substrate with zero disposal issues and the netting is made of PLA. Jiffy Growblocks work perfectly in combination with Jiffy Growbags.
