Hortus IBA Water Soluble Salts — Professional IBA-K Rooting Hormone

Hortus IBA Water Soluble Salts is the professional standard for water-soluble IBA (indole-3-butyric acid) rooting hormone in commercial greenhouse and nursery propagation. Unlike traditional IBA powder formulations that require alcohol to dissolve, Hortus IBA Water Soluble Salts uses the potassium salt form of IBA (IBA-K) — dissolving directly in water for safer, simpler, and more consistent application at any scale.

EPA registered for use in greenhouses and nurseries, with a zero-hour re-entry interval (REI) under the Worker Protection Standard. Available in three sizes to match your propagation volume.
