Grodan 4" Rockwool Cubes - Small Hole (priced per cube)

Grodan cubes are designed to take SBS or similar propagator cubes, which can then be used on their own or placed on a larger stonewool slab.

Three sizes of cubes are available each accommodating a different plug size. The 3" cubes are generally used for tomatoes while the 4" cubes are generally used for peppers and cucumbers and larger root zone or longer term crops.
