Unlike soil and coco, Grodan stone wool is an inert, uniform growing medium that supports precise irrigation and nutrient management, making it ideal for cannabis cultivation. Its consistent structure promotes even water distribution, giving growers greater control over root-zone conditions throughout the crop cycle.
Beyond cultivation, Grodan also supports more sustainable growing practices through stone wool recycling solutions.
Grodan stone wool plugs, blocks, and slabs are designed to support every stage of cannabis cultivation, from propagation through harvest.
Browse by growth stage to find recommended products and growing guidance, or by product family to find the right solution for your operation.
Real-time insights to help growers manage irrigation and steer their crops with greater precision.
GroSens Suite monitors water content (WC), electrical conductivity (EC), and temperature in the root zone. Combined with phase-specific guidance from Grodan's 5-Phase Model, these insights help growers identify trends, refine irrigation strategies, and make more informed decisions throughout the cannabis crop cycle.
