he ideal choice for most plants. The easy to use system was designed to accommodate the 1.5” Grodan A-OK Starter Plug and then support the plants growth right through to harvest. New Grodan Improved! New density + new hydrophilic technology = better water distribution and root development. The uniform distribution of water and nutrients throughout the block allows for more efficient use of the entire substrate volume Full saturation of the blocks with no dry spots and improved EC control with less water is achieved in the rootzone due to the uniform, optimized wool resulting in a sustainable water and nutrient use. Improved “re-wettability” able to more easily increase water concentration in the substrate.
