Growblocks

Jiffy Growblocks contains 100% RHP Certified coco substrate and is delivered to your greenhouse 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, 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.

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.

Professional nursery propagators and bedding plant growers can all save time and money with Jiffy Bump-Up blocks. The growblock contain Jiffy’s own-manufactured 100% RHP certified coco substrate and are delivered dry and compressed to save on transport and storage logistics. Specifically designed to bump-up three or more cuttings in one single step, Jiffy Bump-Up can directly result in a possible labor saving of up to 27%. The Bump-Up growblock itself consists of a medium-and-container block, ideal for nursery propagators to transplant softwood cuttings which can later be bumped up to a larger container. Bedding plant growers can plant three or more cuttings in a Bump-Up and later transplant multiple plants to a final location such as flowerbed, patio container or hanging baskets in one single move.
