Many substances commonly used in the fertilizer industry are harmful to people and the planet. That’s why we design products with cleaner, safer materials to reduce or eliminate dangerous carcinogens and toxins. Reiziger is made from 100% pure, nutritive Dutch ingredients and contains no damaging sulphates, chlorides, carbonates, excess soluble salts, or heavy metals. When used with tap water, these formulations help prevent salt build-up that harms both plants and the environment.
