Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then onto slabs, if desired. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums.
Grodan A-OK plugs are designed for seed and cutting propagation prior to "blocking on" into larger growing blocks. The V-shape design of the plug discourages tangling of roots between the plugs in the A-OK plug sheet. A-OK plugs come in a sheet that fits a standard 10x20 flat.

Grodan Delta constitutes the basis for the uniform and perfectly controllable propagation of plants, the condition to be met for powerful and healthy plant growth. Each block has a virtually identical density, flexibility and sturdiness, guaranteeing a uniform distribution of the WC, EC and pH which in turn results in a uniform and high-quality plant.

Perfectly designed to support medium sized plants through to harvest. The Jumbo is also a great choice to transplant a smaller, well rooted Gro-Block. The 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.
Sold as a Case of 64 Jumbo 6" x 6" x 4" Gro-Blocks.
