1.5" Rockwool Cubes Tray of 77

Rockwool Cubes in Tray are ideal for seed or cutting propagation. For ease of handling, the SBS come in their own handy plastic tray. When rooted, rooting plants can be transplanted into a larger cube or pot once they have been rooted.

Benefits:

• 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
