More than 50 years ago, we noticed a tiny plant growing in a piece of abandoned stone wool on a building site. Just as it's designed to do, nature had found a way to grow. And it inspired us to design a system to support it – a smarter, soilless way of growing that we evolve, explore and refine continuously. A system that promises high yields of consistent, high-quality fresh food and medicinal crops to feed and treat the world's growing population.
The substrate we have innovated to support soilless growing is made of stone wool – a clean and recyclable material formed of natural, abundant basalt rock. It's thanks to this material that soilless growing places minimal strain on our world's precious resources, using up to 20% less fertiliser, 50% less water and 75% less land that can be given back to nature to rest and rewild.

Growing crops, produce and plants soillessly means growing them reliably. Because both the conditions and the stone wool substrate they're grown in are reliable. Every decision made in the greenhouse today has a major impact on tomorrow's results. We support our deeply-rooted knowledge with our digital solutions to improve cultivation from root to fruit.

As the world's population continues to grow, so too does the need for healthy, fresh food and medicinal crops. Since our soilless way of growing isn't dependent on season or location, it can be done anywhere, anytime, meaning it's reliable and consistent – and high yields can be readily available whenever and wherever they're needed.

Since our way of growing is soilless, it supports the human world without depleting the natural one. Using up to 50% less water and 75% less land, higher yields can be reliably achieved with a much smaller physical footprint. Meaning more land can be given back to nature to rest and rewild.

Whatever the crop, our way of growing protects diminishing water supplies. While nothing can thrive without water, soilless growing allows plants to do so with up to 50% less of it than soil-based cultivation. And the water it does use is recycled and reused – as are the nutrients within it.
