Grodan Vital is a high quality producer of rockwool slabs. Since rockwool doesn't contain nutrients and has got a neutral pH value it is especially suitable as a substrate for plant breeding, because adding the right fertilizers is much easier.
Stone wool substrate is a genuine natural product made from volcanic rock, or basalt. Using the latest technologies, the basalt is heated and spun in several directions. This gives it its unique fibre structure. This special ‘Grodan Vital structure’ is characterised by fibres that run in all directions. One advantage of this structure is it facilitates better root distribution throughout the entire slab, as does natural soil. It also encourages the growth of more hair roots in the top part of the slab, which allows the plants to absorb more nutrients.
You can use the Grodan Vital rockwool slab for drip irrigation or irrigation systems in libra boxes. It is crucial to regularly check the pH and EC value of the nutrient solution.
