All-in-one high yield solution

The power of Jiffy Growblocks
The all-in-one medium and container: the Jiffy Growblock is the number one choice for all cut-flower and vegetable growers using hydroponic systems, greenhouses or other nursery applications. And thanks to air-pruning, better temperature control, and versatility, Jiffy Growblocks create healthier, stronger plants in many greenhouses around the world.

Reducing the use of plastic in packaging and production is a global issue, and at Jiffy we aim to lower the use of plastics for our growing media. Since 2019, Jiffy has switched from PE and PP plastics to PLA netting for the manufacturing of all Jiffy Growblocks and Jiffy Pellets. All Jiffy Growblocks now use PLA netting. This is made from polylactic acid (PLA) an alternative to plastic, based on corn starch. PLA netting is a lightweight, fine-fibre web which is biodegradable and compostable under controlled industrial conditions. It is certified under EU norm EN13432.  Jiffy cares for the environment and we are striving to help our customers grow their products in a sustainable or renewable way.

Product Certifications
To guarantee the high quality standard of our products, we certify our product portfolio for organic use, biodegradability, quality, uniformity, etc. This way we help you to meet the requirements your products need in the field for organic production, sustainability, biodegradability and quality.

Jiffy Growblocks

Jiffy 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 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.


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%.

  • Peat free
  • Saving time
  • Solution driven

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.
