GUANO KALONG - GK ORGANICS - HUMIC LIQUID 20% - 500MLNatural Growth Stimulator What is Humic Acid? Humic acid is a natural, water soluble substance at more alkaline pH levels. It forms from the organic decomposition of soil, such as humus or peat, and is produced by microorganisms that break down dead organic matter. Due to its high molecular weight, it improves soil quality and enriches the cultivation substrate, benefiting both traditional and soilless farming systems. Why Choose GK Humic Acid?
