Grodan Rockwool Blocks Small Hole 10 x 10cm (36 pcs)

Grodan stone wool blocks with 27 mm hole diameter (36 pcs.)

Grodan stone wool is spun from molten rock into fine fibres and then pressed into shapes such as cubes, blocks or slabs.
Grodan has a unique position in the market because it produces different types of fibres, unlike other manufacturers who cut everything from one big bale of rock wool. In this way, Grodan aims to support the needs of plants at every planting stage.
Thanks to these special fibres, Grodan rockwool can absorb large amounts of nutrient solution and has a structure that provides plenty of oxygen for faster plant growth.
Grodan is available in standardised sizes. Cuttings started in cubes can easily be transplanted into larger blocks and then onto the sheets, or they can also be transplanted into other growing media such as soil or coco.
