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 various kinds of fibers. The purpose is to give a boost to the requirement of the plant in the different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution at the same time as retaining numerous 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 be transplanted into more traditional planters and growing mediums. Grodan Blocks -Grodan Delta blocks are the most uniform blocks to be had available on the market. They feature improved grooves at the base to promote better drainage. They’re to be had in a large assortment of sizes and configurations to suit all types of plants. These growing blocks are used for direct sowing or “blocking on” of Macro and Multiblock raised plants. AO 36/40 plugs fit well into the hole sizes provided by the blocks. The blocks can then be placed on top of a slab to provide for a larger growing volume. Hugo is the largest of the growing blocks. It provides enough growing volume to give a boost to a larger plant, so it does not want to be placed on top of a slab.
