Grodan Rockwool Cubes 40mm x 40mm



Grodan Rockwool Cubes 40mm x 40mm. Perfectly suited for propagation!

Grodan Rockwool is spun from molten rock into fine fibers and then compressed into shapes like cubes, blocks, or slabs. Grodan has a unique position on the market because of manufacturing various types of fibers compared to other producers who cut everything from one big bale of Rockwool. By doing this Grodan aims to support the needs of the plants in each planting stage. Because of these special fibers, Grodan Rockwool is able to absorb large amounts of the nutrient solution while having a structure that gives plenty of oxygen for faster plant growth.

Grodan comes in standardized sizes. Cuttings that are started in cubes can be easily transplanted into bigger blocks and then onto the slabs or they can also be transplanted into other growing mediums like soil or coco.
