Next Generation 2.0 (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 produce for a growing population.

The uniform treatment of several small batches of plants requires the use of easily managed and uniform mineral wool blocks. Blocks that will also provide optimum conditions for plant development. Following tests carried out two years ago at the Production and Breeding departments at Rijk Zwaan in De Lier, the GRODAN Plantop Delta and Plantop Vitagreen blocks proved to be the best and are now the blocks of choice for the cultivation of young plants.

Sustainability. It's a major global concern. And it is for us at GRODAN too. As producers of stone wool substrates, ‘sustainability’ for GRODAN extends far beyond the boardroom and a few lines on the website. Sustainability is evident in everything we do as an organisation. Not only as our contribution to creating a better world, but also helping growers meet the challenges of the constantly changing marketplace. At GRODAN we're not 'being green' simply for show. For us, sustainability forms the guiding principle underlying our technological innovation. Facilitating even smarter cultivation on stone wool growing blocks and slabs, today and in the future. Good for the environment, good for consumers and good for growers too.

If everything goes according to plan, the first manned mission to Mars will take place in 2035. The journey will take the 'martianauts' about two and a half years. Taking along food supplies for the entire journey is impossible; that would amount to around fifteen hundred kilograms per person. The solution lies in growing their own food. What that requires is a light and compact growth medium which yields maximum results with the use of minimal resources. Precisely the characteristics of the stone wool substrate developed by GRODAN for the horticultural sector.
