Usage:

Before use, we recommend soaking the cubes for a few minutes in a solution with a pH in the range of approx. 4.8 - 5.5, which will bring the pH of the cubes to the same value as the nutrient solution. Let the cube drain. Smaller planting cubes are used for germinating seeds and seedlings, larger growing cubes or compact one-meter mats are intended for the next stages, you can buy everything in our offer.

As soon as the roots start to grow through the cube, the seedlings are ready to transplantation into a larger cube. Cubed plants have a stable position, but the stems of mature, larger plants will likely need support. Grodan products do not have a negative impact on the environment, moreover, they are very economical in relation to water, so they are also suitable for outdoor or organic herb cultivation.
