The benefits of Grodan 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 – Grodan rockwool is easy to re-saturate if it dries out, reducing the risk of root damage
- Nutriculture are Grodan’s master distributor in the UK
