Grodan AX Plugs, rockwool cubes



Grodan AX Plugs 25×40

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.
