Spacing, aeration, irrigation – all are fundamental elements to the growth of a successful crop. These Rockwool Growcube are ideal for helping you to create the perfect growing environment for your plants. The cubes are best used for passive growing, drip irrigation or even with Wilma systems. The Growcubes can be used effectively on their own, but are also ideal for blending with clay pebbles for a perfect balance. Correct use of the cubes is all about creating the right balance of feed. If the environment around your roots is too dense, it can be tough for plants to drain. In addition to over-watering, this can easily lead to disease and unwanted growths. Using these Growcubes is a simple way to improve the drainage below your plants, helping you to manage the amount of water and nutrients each of your plants receives.
