Organic hydroponics

Grow your plants with organic hydroponics

H4O is the world’s first patented organic hydroponic growing system. After more than 10 years of rigorous testing of existing soil-free growing systems, we created our own hybrid solution, which combines the strengths of both methods to make growing simpler. We can say it: H4O is the world’s first patented organic hydroponic growing system!

Our NHS (New Hybrid System)module, combined with vertical NFT (Nutrient Film Technique) systems and towers, makes growing simple in an energy-independent system that takes up very little space and delivers water savings of over 90%. Vegetables and other edible plants grow with natural fertilisers only, without synthetic fertilisers.
