New Grodan Improved! Improved product at current pricing. New density + new hydrophilic technology = better water distribution and root development. The uniform distribution of water and nutrients throughout the block allows for more efficient use of the entire substrate volume Full saturation of the blocks with no dry spots and improved EC control with less water is achieved in the rootzone due to the uniform, optimized wool resulting in a sustainable water and nutrient use. Improved “re-wettability” able to more easily increase water concentration in the substrate.

Each Block has a hole at the top
Gro-block holes are the perfect size for any 1.5" Starter plug or macroplug
Plants can be fully grown in these gro-blocks
The bases of the gro-blocks are grooved to promote drainage and to avoid "wet feet"

Grodan partnered with the Wageningen University and Research Facility and top growers from all over North America to determine the optimal stone wool substrate and irrigation strategies for indoor and greenhouse speciality crops. The result of this scientific rigor is Grodan Gro-Blocks Improved with our Advanced Wetting Agent. These leading edge blocks have the optimal fiber structure and physical properties for crop uniformity, more even Water Content (WC) and Electrical Conductivity (EC) distribution throughout the entire block, and the greatest steering capabilities available. Water distribution is more uniform throughout the entire block which is the basis for a well-defined root system with higher capacities for water and nutrient uptake to produce robust and vigorous crops. These benefits translate to higher yields, improved quality, less water and nutrient usage, and reduced sensitivity of the crop to diseases.

Key features

New and improved wetting agent and hydrophilic technology greatly enhances the water characteristics of Grodan Gro-Blocks Improved giving even better water distribution over the height of the block. This results in greater plant development and steerability and more efficient use of water and nutrients.

Optimized wool structure allows for faster rooting-in and nutrient solution replenishment, all while the Gro-Block Improved maintains its structure, firmness, and rigidity throughout the growing process.
Grodan Rockwool Cubes are one of our most popular items. Suitable for a wide range of plants, Rockwool Cubes are effective in growing anything from tomatoes, lettuce, flowers and even aquatic plants. The cubes are arranged in sheets that make propagating and transplanting easy.

This is a clean product, no pollutants or harmful bacteria. It does not lock up or release any substances, ensuring all water and nutrients are available to the plant. It is easy to control and steer the growth of the crop to achieve higher yields than seen in soil-bound cultivation. Stone wool can be recycled (eg composting).

Grodan’s stone wool are specially designed for irrigation efficiency and uniformity.
