Liquid Humic Acid Concentrate

Humax® is concentrated liquid humic acid (the “black gold of agriculture”). People call this black gold for a good reason.

It increases nutrient availability, promotes nutrient uptake, and stimulates plant growth. Not only that, but it aids in the ability of the soil to hold water. That’s right, it doesn’t just help your plants get more nutrients, but helps make them more drought resistant.

Humax® is an all-purpose soil additive used for vegetables, fruits, trees, and gardens.
