A single-season Grotop Expert slab is the answer for growers looking to combine rapid rooting and initial growth with vegetative crop development. The special fibrous structure promotes root penetration throughout the entire slab, resulting in a more uniform root distribution. In addition, roots are always of excellent quality and color, laying the foundation for thriving plants well-equipped to resist disease pathogens. Slab measures 20 x 7½ x 100 cm (12 pack).
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.
