Hortus IBA Water Soluble Salts by Hortus USA — 1 kg

Hortus IBA Water Soluble Salts is the professional standard for water-soluble IBA (indole-3-butyric acid) rooting hormone used in commercial greenhouse and nursery propagation. The 1 kg size is the preferred choice for large-scale commercial propagation operations running high-volume cutting programs year-round. Unlike traditional IBA formulations, Hortus IBA Water Soluble Salts dissolves directly in water — no alcohol required — making it safer, easier, and more consistent to use at scale.
