Description

Once seeds or cuttings are rooted in a propagation cube, transplant them to a Grodan Delta cube. 3” and 4” cubes are ideal for use in NFT, slab culture, dripper or Ebb & Flood systems. 6” Hugo cube can be used for deep Ebb & Flood tables or passive pot culture.

Remove the plastic sleeve before transplanting into a Nutriculture hydro system for increased oxygen to the root zone and accelerated growth.

3” Small Hole
Delta 4G 27/40 and 27/35 are compatible with SBS 25/150 propagation cubes. Box contains 384 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.
