Description

Grodan’s answer to the pot. Ideal for deep Ebb & Flood tables, drip irrigation or hand watering in a pot. Compatible with SBS 36/77 propagation cubes. Box contains 48 cubes.

The main difference between Polish and Dutch Grodan are as follows;
• Polish Delta 4G and 6.5G Cubes have a slightly larger hole than the Dutch version, in order to accommodate the MM propagation cube.
• Polish 25/150 and 36/77 SBS propagation cubes have a smaller hole than the Dutch version, in which to place the seed or cutting.

More Information

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.
