Grodan SBS Cubes diagonal length: 36mm, 98 pieces.

Grodan propagation cubes for controlled rooting of young plants

The Grodan propagation cubes with a 36 mm diagonal provide a consistent stone wool growing medium for raising cuttings and seedlings. The pre-divided slab contains 98 individual cubes. Stone wool can retain moisture while maintaining air around the root zone, making it particularly useful for controlled propagation and hydroponic growing systems.

98 pre-divided cubes for organised propagation

Each cube can hold one cutting or seedling. The cubes are supplied together as a pre-divided slab and can be separated whenever required. This is useful when young plants need to be spaced individually during rooting. More suitable products for this stage can be found in the propagation media range.

Stone wool for hydroponic growing

Grodan develops stone wool growing media for professional horticulture. The material combines good water retention with aeration within the root zone, allowing irrigation and nutrient delivery to be managed precisely. Adequate drainage remains important so that excess nutrient solution can leave the growing medium freely. Further compatible products are available in the rockwool growing media category.

Easy transition to larger growing media

With their 36 mm diagonal size, the cubes are designed for compact propagation and can be transferred into suitable larger stone wool blocks once the young plants have developed sufficient roots. If you prefer a propagation system supplied with a separate plastic tray, the Grodan SBS 36/77 propagation cubes with tray are a suitable alternative.
