Why Choose Rockwool Slabs for Hydroponic Growing?

Rockwool is widely used in professional hydroponic setups due to its high capillary action, meaning it efficiently distributes water and nutrients to the entire root zone. This ensures consistent feeding and reduces the risk of dry spots, leading to stronger, more resilient plants.

Unlike soil-based mediums, Rockwool is inert and sterile, minimising the risk of pests, diseases, and nutrient imbalances.

How to Use Rockwool Slabs:

1. Pre-soak in pH-Adjusted Water – Before planting, soak the slab in a solution adjusted to pH 5.5–6.0 to stabilise its pH.
2. Place in Grow System – Position the slab in your hydroponic system or trays for easy access.
3. Insert Clones or Seeds – Use Rockwool cubes or plugs for germination, then transplant into the slab.
4. Maintain Proper Irrigation – Monitor water levels to ensure the slab stays moist but not oversaturated.
5. Monitor & Adjust pH – Keep the pH in the optimal range of 5.5–6.5 for best nutrient uptake.
