Grodan Vital, based on the Next Generation technology, can be saturated faster and more effectively. The water content and EC are also distributed more uniformly throughout the slabs and amongst the individual slabs.

As a result, Grodan Vital offers a wide control range to steer your crop using a simple irrigation strategy. This makes Grodan Vital the ideal solution for growers seeking a reliable substrate that facilitates easy irrigation and leaves nothing to chance throughout the cultivation period.

Grodan Vital is extremely versatile and lends itself perfectly to cultivating the most important vegetable crops such as tomatoes, sweet peppers, cucumbers and aubergines. Tomatoes can benefit from the uniform water distribution and good EC replacement offered by Grodan Vital, while sweet peppers will show fast growth, uniform stem development and early setting.

Grodan Rockwool is the leading rockwool company worldwide. Using a base of basalt and limestone, the mixture is heated to 1500°C and then poured onto fast-spinning disks. The result is the highest-quality rockwool, containing only 5% rock content. Because of the low density of the rockwool, it provides exceptional capillary action for the roots, while retaining enough water for growth.

Completely inert, rockwool is ideal for hydroponic growers. It will not buffer the pH of the solution, nor degrade into soluble parts that could affect your plant.

Rockwool must be prepared prior to use, and it is best to soak the cubes for 24 hours in a light nutrient solution that has been pH adjusted to 5.2-6.
