Hormex Rooting Hormone Powder Set (#1, #3, #8, #16) — Rooting Powders

Contents and pack size: This kit contains four separate 21g bottles of rooting powder labeled #1, #3, #8 and #16. Each bottle is intended for a different rooting task so you have a selection on hand for a wide variety of plants.

Concentrations and intended use: The four formulas correspond to IBA levels of 0.1, 0.3, 0.8 and 1.6, providing gentler to stronger hormone doses for softwood, semi-hardwood and hardwood cuttings. They are suitable for common ornamentals, rare specimens, fruiting plants, vegetables, medicinal species and young trees.

Compatible media and systems: These powders are formulated to perform in rockwool, coco coir, peat mixes, standard potting soils and other propagation media. They’re effective for both hydroponic cloning setups and traditional soil-based propagation; pair them with rooting cubes for consistent placement and moisture control.

Formula and provenance: Made in the USA, the powders use a clean, minimalist ingredient approach and are part of a long-running product line relied on by hobbyists and professionals for decades. The simple formulation is intended to minimize contaminants while promoting root initiation on a wide range of species.

How to use: Take a healthy 3–8 inch stem and make a 45° cut below a node. Briefly dip the cutting in water or a compatible liquid preparatory dip, then evenly coat the basal end with the chosen powder. Insert the treated end into your rooting medium or a dedicated rooting cube, ensuring good contact.

Care after planting: Maintain elevated humidity and consistent bottom or ambient heat appropriate to the species you’re propagating. Keep light levels moderate until roots establish, avoid overwatering, and transplant once a robust root system forms.
