The mystery behind Fulvic & Humic Acids

If you don’t know the differences between Humic and Fulvic acids don’t worry, you are not the only one. Even the USDA regulators are not able to make a formal definition on these two amazing products.

Humic and Fulvic acids are by far one of the most effective bio stimulants you could find in nature. These two product guarantees an overall improvement in the up taking of nutrients in both soil and hydroponics.

Humic and Fulvic acids are quite different, but as soon as you can understand these differences, you would be able to see what they are so important to your garden.

Before we can start, we have to know a little bit about Chelators. Chelates are organic molecules that attach to mineral ions like a claw, holding them tightly enough so they don’t get locked up in the soil, but loosely enough so they are available to the plant on demand.

Let’s take a look and see how important Humic & Fulvic acids are for both Soil & Hydroponics Systems

Improve Nutrient Absorption & Transportation

The Humic acid consists of larger molecules with lots of positive and negative charges on the surface of the molecules. It has the ability to hold onto minerals in the root zone, making them much more available to plants. Humic acid forms a bridge between the clay particles and the mineral cations.

The Fulvic acid has a much smaller but more biologically active. Fulvic can help transport mineral ions through the cell membrane and release them inside the cell.  Fulvic acid makes a great foliar spray, allowing trace elements such as copper, iron, manganese and zinc to be better absorbed through the leaves.

The perfect Soil Enhancer

In soil, Humic and Fulvic acids help with the uptake of iron. Iron is a catalyst for chlorophyll production, so as plants take up more iron, they make more of the green pigment that harvests light energy to make sugars. Humic acid when added to the root zone stimulates the uptake of nitrates and other essential elements.

The powerful combination (Recommended)

Fulvic and Humic Acid, combined with Seaweed is a very powerful mix. Seaweed extracts are loaded with natural plant-growth hormones such as auxins and cytokinins. Humic and Fulvic acids hold onto the auxins in an exchangeable form to amplify their effects on plants.

The best Nutrient for sick clones

Fulvic Acids & Seaweed make a great tonic for sick clones when used as a foliar, If your cuttings are having issues to root, or if the leaves start to turn yellow and fall off, try using a fine mist of Fulvic acid and seaweed at the recommended 5:2 ratio. Plants will respond to Fulvic acids in a time frame about 3 to 4 hours, and vigorous root growth and stress recovery is often evident in as little as 3 days.

Effective Anti-stress formula for plants

Humic and Fulvic Acids protect your plants against stress. The use of these acids stimulates the production of superoxide dismutase (SOD) which is an enzyme that protects chloroplast and the membrane of the cell. Remember! It works better when combined with seaweed.

For Advanced Hydroponics Grower

In hydroponics, the use of Fulvic and Humic acids will depend on the kind of water you are using in your system. For example: If you use reverse osmosis water (RO), Humic acid may be a slightly better choice because it contains both Humic and Fulvic acid fractions and it has a buffering effect on pH.

On the other hand, If you use hard water, Fulvic acid would be a better option. Hard water is usually high in calcium and magnesium ions. Since Fulvic acid molecules are smaller than Humic fractions, they are better at surrounding the calcium ions to help keep them soluble and available to plants.

Fulvic acid is also more acidic than most Humic acid products. Since hard water is generally higher in pH, Fulvic acid may be a better choice when using well water in hydroponics.

Complete Hydroponics nutrients are recognized for its highly balanced concentrations of Fulvic and Humic acids:

For example:

For Deep water Culture & Coco Coir

These Hydroponic Nutrients such as Agua A&B and Coco A&B contain highly balanced concentrations of Fulvic and Humic Acids. However, Fulvic acids are predominant in these formulas because as we mentioned before, Fulvic molecules are smaller and woks better in water solutions helping out the overall uptake of minerals and nutrients by your plants either through the roots or through their leaves (foliar).

On the other hand we have the following nutrient:

For Soil and Soil-mixed growing mediums Tierra A&B


Tierra A&B contains highly balanced concentrations of Both Humic and Fulvic acids but the predominant aggregate is Humic Acids. This is because Humic acids perform much better in soils and most importantly, these wonderful elements have a particular pH buffering effect in both soil and water.
