Description
3 inch = 75mm / 4" = 100mm Grodan cubes come in small and large hole, depending on your starting rockwool plug.
Propagation
of young plants is the basis for optimal cultivation results. High demands are
placed on substrates, especially during the propagation phase. Uniformity and
the degree of water retention are critical success factors.
Growers are increasingly focusing on desired crop development; this is partly
determined by the variety that is selected, and the desired plant type. Factors
that influence the choice of variety include the plant size, the required vine
development with tomatoes or whether crops are grown under natural or grow
lights. Propagators steer how crop variety is propagated on the basis of
climate and irrigation strategy. The choice of blocks largely determines the
irrigation strategy, which ultimately yields the type of plant required by the
grower. Grodan offers a wide range of blocks and plugs that yield uniform
plants under various cultivation conditions.
