Completely sterile and inert ideal hydroponic growing medium. Reduced risk of pests and disease.
Even root growth predominantly vertical fibre structure means identical resistance levels for each root, so roots grow evenly.
The increased root development structure of the rockwool is designed for optimum air/water balance and accelerated rooting.
Uniformity quality and structure are 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.
Available in: single cubes 25mm or 36mm,
A full tray of 25mm/150 cubes and 36mm / 77 cubes,
