Product detailed description

Grodan Improved Gro Block 100×100×100 mm – premium MEDICAL-grade growing block

Grodan Improved Gro Block 100×100×100 mm is a top-quality growing block made from rock (basalt) wool, developed for professional cultivation of demanding annual plants in fully controlled conditions – in indoor operations and in greenhouses. The pre-prepared 40×40 mm hole allows quick, clean and precise transplanting of rooted seedlings or cuttings without damaging the root system.

MEDICAL quality – the highest standard of purity and consistency

This range falls into the MEDICAL category and is manufactured in line with the strictest requirements for purity and hygiene. The material is inert and chemically neutral, and contains no pathogens, weeds or residues of organic impurities. It therefore provides a sterile and fully predictable root environment in which plants start faster, more evenly and maintain consistent quality throughout the growing cycle – exactly what professional and pharmaceutical operations require.

Advanced wetting technology (Advanced Wetting Agent)

Grodan Improved was developed in cooperation with Wageningen University & Research in the Netherlands and tested by leading growing operations. The result is improved rock wool with advanced wetting technology, which ensures exceptionally even distribution of water and nutrient solution throughout the entire block. This brings faster rooting, more precise control over irrigation (crop steering), stable moisture in the root zone and lower sensitivity of the crop to diseases.

Why is the price higher than a standard Grodan block?

Unlike standard blocks, Grodan Improved material is vulcanised – the rock wool fibres are processed at high temperatures into a firm, stable and long-term dimensionally stable structure. This more demanding manufacturing process, together with advanced wetting technology and certified MEDICAL quality, ensures a longer block life, more consistent water distribution and more reliable results. The higher purchase price is therefore returned in the form of a healthier root system, lower losses and higher crop quality.

Frequently asked questions

For which plants is Grodan Improved suitable?

The block is intended for demanding annual plants grown in controlled conditions – in indoor operations and in greenhouses, where emphasis is placed on cleanliness, consistency and precise irrigation control.

How does it differ from a standard Grodan block?

Grodan Improved uses vulcanised rock wool and advanced wetting technology (Advanced Wetting Agent), which ensures more even distribution of water and nutrients, faster rooting and a more stable root environment than standard blocks.

Why is Grodan Improved more expensive?

The higher price reflects the more demanding manufacturing process of the vulcanised material, advanced wetting technology and certified MEDICAL quality. All of this contributes to a longer service life, more reliable results and higher crop quality.

What is the 40×40 mm hole for?

The 40×40 mm hole allows easy and precise insertion of a rooted seedling or cutting without damaging the roots and ensures the plant sits firmly in the block.

Is the material reusable and environmentally friendly?

Grodan rock wool is inert and dimensionally stable. Thanks to its firm vulcanised structure, it retains its properties over the long term throughout the entire growing cycle.
