Fulvic Acid 10%

R153 - R1 190


Fulvic Acid from Green Houston is a natural biostimulant that is derived from humus. Humus is the organic component of soil, formed by the decomposition of leaves and other plant material by soil microorganisms.

Fulvic Acid helps your plants grow healthier and stronger at faster rates by delivering trace minerals straight into the plant cells. Fulvic acid acts as a chelator, meaning it binds to inorganic micronutrients like zinc and copper and makes them available to plants. These micronutrients are essential for healthy crops and sustainability

Due to the low molecular weight, Fulvic Acid can cross the membrane of your plants and penetrate directly into leaves. This makes Fulvic Acid highly effective when used as a foliar spray.

    How To Use

    • Dilute 2ml – 8ml per 1L of water and apply around the root zone. 
    • For soil beds more can be used 10ml-40ml per 1L.
    • Begin using Humic Acid when the plants are transitioning from the seedling phase to the growth phase to build a steady root foundation,
    • Begin to use Fulvic Acid a week later to stimulate growth.
    • We recommend using both Humic Acid in conjunction with Fulvic Acid for optimal performance.
    • Do not use it with seedlings unless you significantly decrease the dosage as it is too concentrated.
    • We recommend lowering your liquid nutrient feeding program(i.e. Biobizz, GHE and so on) by at least 10% to avoid nutrient burn.


    Please note:

    Biobizz Top-max and root juice contains fulvic acid and humic acid respectively.
