Aqua Gardening Suggests These are Best For

Grodan Rockwool 98 Cube Slabs are best suited for gardeners and cultivators of all experience levels, from novices to professional growers. They are especially beneficial for those seeking an efficient and easy way to manage the early stages of plant growth, such as raising seedlings and cuttings.

The hydroponic growing media of choice

Grodan Rockwool or stonewool is made from molten rock spun into cotton candy-like fibres and then compressed into cubes, blocks or slabs. Rockwools superb quality, fibre structure and pathogen-free content enables optimal root development for unrivaled growth and production. Grodan has the highest density on the market, which translates into the greatest structural integrity for increased and longer oxygen holding capabilities. Low density rockwool collapses with the weight from water and plants, squeezing out air pockets and decreasing oxygen retention. High density gives better insulation value which is especially important during germination and rooting of cuttings. Higher density also improves the wicking and dispersion of moisture and nutrients, enticing roots into more areas of the medium, and therefore increasing nutrient fueled sites for premium plant production.
