Grodan is the name in stone wool, and for good reason. The optimised wool structure saturates faster and more evenly than cheaper alternatives, and holds its shape and firmness right through a long crop rather than slumping.
The range covers propagation cubes, Gro-Blocks and Improved Hugo blocks in 3, 4 and 6 inch with small, large and dripper holes, plus Vital slabs in 1m and 1.3m.
