RAW Humic Acid | 59% Concentrated Humic Biostimulant | Root Zone Enhancer

RAW Humic Acid is a 59% concentrated, water-soluble humic acid derived from leonardite. More than a supplement, humic acid is a root-zone biostimulant that improves nutrient uptake, buffers soil pH, and energizes plants to grow stronger, faster, and more resilient.

Expanded Description:
Humic acid isn’t a fertilizer—it’s a biostimulant that makes fertilizers work harder for your plants. By improving nutrient uptake, water absorption, and root health, humic acid builds the foundation for growth, yield, and stress resistance.

RAW Humic Acid delivers one of the most concentrated and soluble forms on the market, making it easy to use in soil, hydroponics, or even RO water.

• Nutrient Uptake Engine: Humic acid improves the efficiency of fertilizer use by binding minerals and making them more available for absorption at the roots.

• “Battery Effect”: As agronomist Harley Smith explains, humic (and fulvic) acids increase the voltage potential across plant cell membranes. This creates the energy plants need to pull in trace elements like iron, manganese, and copper more effectively—fueling faster growth and stronger resistance.

• pH Buffering: Naturally balances acidic or alkaline soils, creating a more stable root zone.

• Root and Microbe Support: Enhances cation exchange capacity (CEC), stimulates beneficial microbes, and encourages robust root systems.

• Proven Synergy: RAW Humic Acid is most effective at the root zone, especially when paired with RAW Kelp in the Virginia Tech–proven 5:2 humic-to-kelp ratio, a combination shown to amplify nutrient uptake and microbial activity.

RAW Humic Acid is fully soluble and integrates easily into any nutrient program, whether in soil, coco, or hydro systems.
