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.
4” Large Hole
Delta 6.5G 42/40 and 40/35 are compatible with SBS 36/77 propagation cubes. Box contains 216 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.
