NG 2.0 Technology

NG2.0 is the latest substrate technology from Grodan. This technology enables propagators and growers to produce more while using less water, nutrients and space. It creates optimal growing conditions for a whole season, and allows roots to make better use of the entire substrate. NG2.0 is available in plugs, blocks and slabs to help growers and propagators produce sustainably, healthy fresh vegetables for a growing population.

What is EC?

Electrical conductivity or "EC" is a measure of the “total salts” concentration in the nutrient solution (drip, slab or drain). The higher the “total salts” concentration in a substrate the higher the EC. An EC will only be registered when inorganic ions are present in solution.

This essentially distinguishes animals, including Man, from plants.
