Rockwool 8inch Cubes Big Daddy

The benefits of rockwool 

• Completely sterile and inert – ideal hydroponic growing medium. Reduced risk of pests and disease. 
• Even root growth – predominantly vertical fibre structure means identical levels of resistance for each root, so roots grow evenly. 
• Increased root development – structure of the rockwool is designed for optimum air / water balance and accelerated rooting. 
• Uniformity – quality and structure is uniform, so water content and EC (CF) will remain the same for every plant. 
• Re-wetting – rockwool is easy to re-saturate if it dries out, reducing the risk of root damage.
