Our solutions combine hardware, AI and bioscience to recreate a wide range of environmental conditions, enabling plants, fungi and microorganisms to grow faster and more efficiently.

On Earth, we are pioneering molecular and bio-farming, increasing the production of nutrients, metabolites and bioactive compounds in plants while providing a sustainable and safe source of plant materials. Our customers include leading companies in the beauty, perfume, natural ingredients, food & beverage and nutraceutical industries.
