Grodan Improved Uni-Slab – Growing Slab 35 x 15 x 7.5 cm with 1 Planting Hole

The Grodan Improved Uni-Slab is a compact, professional stone wool growing slab measuring 350 x 150 x 75 mm, featuring one pre-cut planting opening of 100 x 100 mm. This growing slab is designed for single-plant cultivation in professional hydroponic and controlled growing systems.

Thanks to its optimised vertical fibre structure and Advanced Wetting Agent technology, water is distributed uniformly throughout the entire substrate volume. This supports consistent root development and enables precise management of water content (WC) and electrical conductivity (EC).

Improved capillary action provides uniform moisture distribution and rapid resaturation, even after significant drybacks. This allows growers to adjust irrigation strategies according to the plant's growth stage and implement both vegetative and generative crop steering techniques.

The compact Uni-Slab provides an individual root zone for each plant and can be combined with compatible Grodan Improved Gro-Blocks featuring a 10 x 10 cm base. The slab is suitable for professional drip irrigation and precise nutrient management.
