Improving your Cannabis yields with Fulvic and Humic Acids
Fulvic acid has both direct and indirect effects on plant growth. Indirect effects comprise of the factors that; make available energy for use by organisms in the soil, influence water retention, improve soil structure, avail trace elements to the plants and influence soil fertility. Direct effects comprise of the changes in plant metabolism that take place after the application of fulvic acid and humic acids (Smith, 2017).
Fulvic acid help mediate the uptake of essential mineral elements contributing to improved plant growth. One stimulating influence of fulvic and humic acid on plant growth is the absorption of mineral elements such as nitrogen, potassium and phosphorus. The small size of fulvic acid molecules enables plants to readily uptake nutrients. Also, fulvic acids act as chelators preventing different nutrients from reacting with each other before plants can uptake them increasing the ability of plants to take up nutrients for better growth. This effect enables plants to absorb different nutrients more efficiently, therefore, facilitating stronger growth.
The uptake of fulvic and humic substances has a positive impact on seed germination. The application of fulvic acid improves seed germination rates. When fulvic acid enters the seed cells, there is an increase in cell division and respiration rates. The increase in respiration rate plays a crucial role in root meristem development and helps activate several growing points in the seedlings.
Fulvic acid has a significant impact on root initiation and improved root development. Fulvic acid acts as a root stimulator. Accordingly, there is further stimulation of root growth when fulvic acid is applied together with humic acid (Smith, 2017). The small molecules of fulvic acid play a significant role in root stimulation. Nevertheless, fulvic and humic acid provides plant cells with free radicals which act as electron donors. Free radicals have positive impacts on seed germination, root development and the overall plant growth.
When applied together with trace elements and foliar sprays, fulvic acid helps increase the growth of plant foliage, fruits and roots. An increase in plant growth positively impacts processes in the leaves and the stem, therefore, increasing the carbohydrate content stored in these parts. Fulvic acid enhances the metabolic processes and the carbohydrate production. Thus, there is an increase in the overall plant yields and brix levels. As so, higher brix levels in cannabis plants will directly lead to stronger resilience against pests and diseases, increased resin and oil production, as well as increased terpene production.
Fulvic acid plays a vital role in the uptake of iron. Fulvic acid prevents iron from being oxidized and turning into rust by keeping it in soluble form. Fulvic acid also enables plant membranes to easily absorb iron (Bocanegra, Lobartini, & Orioli, 2006). Iron acts as a catalyst, as the plant takes up more iron, it increases its green pigment that absorbs light to manufacture sugars. These sugars provide energy for plant growth and also act as food stores. Hence, increased food stores contribute to an increase in crop yields.
Fulvic and humic acid directly impact the plant cell membranes. Fulvic acid increases permeability causing improvement in the transportation of minerals to plant parts of metabolic need. Moreover, fulvic acid accelerates the chlorophyll content in the leaves. An increase in the chlorophyll content in the leaves has a direct impact on the uptake of oxygen. Fulvic acid also elevates the concentration of messenger ribonucleic acid which is beneficial for their effect on the biochemical processes in plant cells. Increase in biochemical processes causes increased enzyme synthesis and protein content.
Ultimately, fulvic acid acts as a protector of plants against stress. Stress in plants can be a significant contributor to reduced yields. Fulvic and humic acid enable a plant to produce a protective agent called superoxide dismutase (SOD). SOD helps sponge the free radicals and shields chloroplasts and cell membranes. Increased SOD levels guard plants against stress resulting from drought (Anjum, Wang, Farooq, Xue, & Ali, 2011). Hence, at such adverse conditions, crops can maintain their yields.
Indeed, fulvic acid plays a crucial role in improving plant growth and yields. The role of fulvic acid in enhancing plant growth and yields is clear, which is why we strongly advise at incorporating some type of fulvic/humic in your regiment. If you’re having trouble deciding on a fulvic/humic product, then it’s the perfect time to try FulBase our carbohydrate derived fulvic acid/humic acid product into your gardens.

Fulvic acid can be applied in different growing situations to improve plant growth and plant yields. This article explains the reason behind the comprehensive application of fulvic acid in areas such as organic plant production horticultural programs and greenhouses. Fulvic acid has both direct and indirect effects on
Humic and fulvic acids for cannabis plants
The use of humic and fulvic acids is becoming increasingly popular among all types of cannabis farmers, who can now take advantage of a healthy, rich and living soil that produces happy plants and therefore abundant harvests. Thanks to this substances, nutrient uptake and management are much more efficient, and root growth is simply spectacular.
Either if you’re using organic soil or hydroponic systems, using humic and fulvic acids is a very easy way to ensure the best possible conditions for the roots of your plants. Indeed, it is especially recommended in hydroponic cultivation since these types of growing media do not contain nutrients nor microbial life. In this way, you get the most out of the nutrient solution that you’ve carefully prepared for your plants.
Quality soil produces quality flowers
Soil organic matter
Soil is composed by many substances, some of them resulting from a transformation process of certain molecules. Among the organic components of soil, we can find living organisms on the one hand and organic matter on the other, which usually comes from chemical and microbial transformation processes of organic wastes contained in the soil.
In turn, we can divide this organic matter into unaltered material (fresh, not processed or modified) and altered material (sometimes called humus), which are byproducts physically and chemically different from the substances they come from. Sometimes, the process from which this altered material is formed is called humification.
Finally, altered material can be divided into non-humic substances (aminoacids, lipids, carbohydrates) and humic substances, which are the ones we’re dealing with today. The term “humic” is generic, which means it is applied to different materials normally classified according to solubility levels:
- Humic acids
- Fulvic acids
- Humin (non-soluble humic substances)
Most humic and fulvic acids on sale today come from leonardite, an earthy substance which comes from an unfinished carbonisation process. During this transformation, organic waste is compressed and heated over time, being slowly transformed into peat, then lignite, coal and finally anthracite (leonardite is formed when peat is transformed into lignite). The high content of these substances present in leonardite, as well as their high bioactivity, has put leonardite as main source of humic substances.
What are humic acids?
As a result of the breakdown of organic matter in the soil by microbial life, humic acids are dark coloured macromolecules soluble in alkaline water which have become an excellent choice to improve the properties of the soil due to their high molecular weight. At the same time, they provide better management and mobility of the nutrients available in the substrate and highly improve water retention.
Thanks to their chelating action, they adhere to micronutrients present in the growing medium and create a bond with which they are better absorbed by the roots of the plants. In this way, both the cation exchange capacity and the buffering capacity of the substrate are improved, which is translated into better plant development. They also allow for better nutrient release from the soil while highly improving micronutrient uptake, which can save many problems derived from this – often difficult to diagnose – type of nutrient deficiency.
Humic acids are complex macromolecules
What are fulvic acids?
Fulvic acids are humic material of yellowish colour, similar to the former although they have less carbon and more hydrogen in their molecular composition (molecular weight is then lower). They’re macromolecules soluble in water (either acid or alkaline) and especially skillful when it comes to crossing the membrane of plant cells.
That’s one of the main reasons why fulvic acids are often used via foliar spraying so they’re quickly absorbed. However, they can also be used via irrigation mixed with your regular nutrient solution. They’re ideal as fast-acting agents, being excellent root boosters.
Humic and fulvic acids for cannabis cultivation
Now that we have a much clearer idea of what exactly are these substances and how they act, it is not surprising for us that an incresing number of growers (especially professionals) has chosen humic and fulvic acids in order to reduce the amount of nutrients used and obtain better harvests. This means more income with less expenses, something that any grower seeks.
Let’s summarize now the potential benefits of using humic and fulvic acids for cannabis cultivation:
- Water retention, microbial activity and cation exchange are highly increased
- Improvement of drainage and buffering capacity of the soil
- Better nutrient uptake (chelating action) and mobility, also via foliar
- Soil toxins are less available for the plants
- Plant metabolism is enhanced, being ideal for seed germination, rooting and transplants
- Enhancement of cell division, improving growth rates
- Photosynthesis is stimulated, being ideal for plants in shady areas (especially fulvic acids applied via foliar)
