Grodan Improved Uni-Slab – Growing Slab 30 x 19.5 x 10 cm with 1 Planting Hole

The Grodan Improved Uni-Slab is a professional stone wool growing slab measuring 300 x 195 x 100 mm, featuring one pre-cut planting opening of 100 x 100 mm. This compact growing slab is designed for single-plant cultivation in professional hydroponic and controlled growing systems.

Grodan Improved technology combines an optimised vertical fibre structure with Advanced Wetting Agent technology. This promotes uniform distribution of water and nutrients throughout the entire substrate volume while supporting consistent root development.

Improved capillary action and rapid resaturation allow precise management of water content (WC) and electrical conductivity (EC). Growers can apply different irrigation strategies and implement both vegetative and generative crop steering.

Thanks to its single-plant design, the Uni-Slab provides an individual root zone for each plant. The pre-cut planting opening accommodates compatible Grodan Improved Gro-Blocks with a 10 x 10 cm base.
