Hormex Rooting Powder Combo (0.1-1.6 IBA) - Rooting Hormone

In this review of Hormex Rooting Powder Combo the bottom line is straightforward: this is a practical choice for gardeners who want a reliable rooting hormone across a range of cutting types. The combo supplies multiple strengths of Indole-3-Butyric Acid so users can match concentration to softwood, semi-hardwood or hardwood cuttings, which is the single biggest reason to buy. The powders are simple to use, free of alcohol and dyes, and the formula is designed for higher cloning success with common ornamentals, fruits, vegetables and medicinal plants.

Key Features

• Multiple strengths: The set includes 0.1, 0.3, 0.8 and 1.6 IBA options so you can select an appropriate strength for soft, semi-hard or hardwood cuttings.
• Proven rooting compound: Contains Indole-3-Butyric Acid (IBA), a widely used rooting hormone that promotes stronger, healthier root systems for a wide range of species.
• Clean formula: Free of alcohol, dyes and preservatives, making it suitable for sensitive, rare or medicinal plants and reducing unwanted additives.
• Works with many media: Effective when used with rockwool, coco coir, peat, soil, clay pellets and other starter mixes for flexible propagation methods.
• Easy application: The powder application method is straightforward-dip in water or concentrate, coat cut end, tap off excess and plant-so beginners can follow standard cloning technique.
• Made in the USA: A long-standing formula from a manufacturer with a history in rooting products, offering consistency and availability.

Who It's For

The Hormex combo is best for hobbyists, small-scale growers and plant enthusiasts who propagate a variety of species and need tailored concentrations for different wood types. It particularly suits those cloning ornamentals, fruit cuttings, vegetables and medicinal plants who want options rather than a single-strength powder.

It is less necessary for someone who only ever propagates a single, easy-to-root annual or for gardeners who prefer liquid hormone systems exclusively; those users may find a single-strength product or a liquid concentrate more convenient.
