Grodan Delta Rockwool Cubes

Grodan Rockwool Cubes

Grodan Delta Rockwool Cubes are ideal for use in NFT systems. Once seeds or cuttings are rooted in propagation cubes, they can be transplanted into Grodan Delta cubes.

Grodan Delta Rockwool Cubes have a plastic sleeve that must be removed before transplanting into a hydro system for increased oxygen to the root zone and accelerated growth.

Cubes are approximately 3″ or 4″ square, and have a 1″ hole in the centre.

Benefits:

• Completely sterile and inert and ideal hydroponic growing
• Reduced risk of pests and disease
• Even root growth thanks to predominantly vertical fibre structure
• Designed for optimum air / water balance resulting in increased root growth
• Uniform quality and structure so water content and EC (CF) will remain the same for all plants
• Easy to re-saturate if it dries out, reducing the risk of root damage
