Growblock Jiffy

Price range: 58,00 € through 251,00 € HT

Growblock Jiffy is an all-in-one growing medium made from 100 % RHP-certified coconut coir, designed for professional growers of cut flowers, vegetables and hydroponic crops. Supplied dehydrated and compressed, it expands instantly when watered to form a ready-to-use cube surrounded by biodegradable PLA netting — a sustainable alternative to conventional plastics.

Its water retention of 60 to 75 % and air porosity of 20 to 35 % ensure optimal rooting and stronger plants. Compatible with all types of fertilization, it is suitable for both propagating cuttings and growing crops through to harvest, in greenhouses, nurseries or hydroponic systems.

Growblock Jiffy – All-in-one coconut coir growing medium

Features

Growblock stands out for its carefully engineered design. It is designed to maximize root development while simplifying logistics for growers:

  1. Compact format, supplied dehydrated: each block comes as a compressed slab surrounded by netting, making it much easier to transport and store before use.
  2. Instant expansion with water: on contact with water, the slab expands within minutes to form a ready-to-use cube, with no complicated handling.
  3. PLA support netting: unlike conventional PE or PP plastic netting, Growblock is wrapped in PLA (polylactic acid) netting, a biodegradable bioplastic made from corn starch.
  4. Optimized water retention capacity: between 60 and 75 %, ensuring consistent root hydration without excess water.
  5. Controlled air porosity: 20 to 35 % air, ensuring optimal oxygen diffusion in the root zone, a key factor in plant health.

These technical features make Growblock a particularly sought-after growing medium among professionals who want precise control over their crops’ growing conditions.

Benefits

Choosing a growing medium is not just about its composition. It is also a strategic decision that can optimize your yields and operations. Here are the main benefits reported by Growblock Jiffy users:

  1. Higher yields: thanks to an optimal root environment, plants grown in Growblock show more uniform and vigorous growth.
  2. Stronger, healthier plants: better control of temperature and moisture in the growing medium promotes fast, robust rooting.
  3. Significant time savings: the ready-to-use format, once hydrated, reduces the preparation steps usually required with other growing media.
  4. Reduced labor: less handling, less repotting and fewer repetitive technical tasks along the production line.
  5. Easier storage and transport: the compressed format optimizes logistics space, a considerable advantage for large-scale operations.

These benefits explain why Growblock has become a trusted choice among growers seeking both agronomic performance and ease of use in their daily operations.

Composition

Growblock’s composition has been designed to meet the demands of modern, sustainable and environmentally responsible agriculture:

  1. 100 % RHP-certified coconut coir growing medium. A natural, washed and stabilized material, carefully selected for its water retention and aeration properties.
  2. Biodegradable PLA netting: since 2019, this corn starch-based netting has replaced conventional plastic netting. It is certified to comply with European standard EN13432, confirming its biodegradability and compostability under controlled industrial conditions.
  3. Peat-free growing medium: an essential feature for growers who want to protect peatlands, a natural resource that is nonrenewable on a human timescale.
  4. Coconut coir from sustainably managed plantations. Ensuring responsible production, from sourcing the raw material to manufacturing the block.
  5. Certified organic and biodegradable product, meeting the strictest specifications for sustainable agriculture.
  6. Growing blocks ready to use.
  7. Several sizes of growing blocks available with or without a hole / Dimensions (cm): 50 x 50 x 50mm /80 x 80 x 65mm / 100 x 100 x 65mm

This composition makes Growblock both agronomically effective and environmentally responsible. These two criteria are becoming increasingly important when choosing a professional growing medium.

Why choose Growblock Jiffy?

By combining the growing medium and its container in a single block, Growblock simplifies cultivation. RHP-certified coconut coir provides consistent physical properties from batch to batch, an essential consideration for growers who cannot afford quality variations between growing cycles.

In short, Growblock Jiffy is a worthwhile investment for any professional grower looking to combine yield, convenience and environmental responsibility in a single growing solution.
