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 it into a Nutriculture hydro system for increased oxygen to the root zone and accelerated growth.

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 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.
