Can You Grow Hydroponics Without Nutrients?

Nutrients are the cornerstone of any hydroponic system, and because we will need to meet all the plant nutrient requirements, it is essential to understand what you’re providing and what can go wrong.

Nutrients are the cornerstone of any hydroponic system, and because we will need to meet all the plant nutrient requirements, it is essential to understand what you’re providing and what can go wrong.

With any nutrient solution, both factors to keep in mind are firstly the makeup of your nutritional supplement — does it contain all the elements needed for plant growth in the appropriate ratios. And second, with your balanced and complete nutrient solution, what strength or’EC’ is operating at for your specific crop, stage of growth, and type of hydroponic system, and how can we measure this.

To be ‘complete,’ a hydroponic nutrient should get the vital elements for plant growth, by the following: Nitrogen (N), Potassium (K), Phosphorus (P), Calcium (Ca), Magnesium (Mg), Sulphur (S), Iron (Fe) Manganese (Mn) Copper (Cu) Zinc (Zn) Molybdate (Mo) Boron (B) Chlorine (Cl) The amounts that these elements are found in your hydroponic nutrient tend to vary between manufacturers as there’s no one single recommendation for concentrations.

Can You Grow Hydroponics Without Nutrients?

Growing plants in a hydroponics system eliminate the need for soil. But without soil, your plants will not have any access to the components they need to succeed.

Your indoor garden won’t grow without these essential elements and has to receive them in the kind of hydroponic nutrients which will be blended into your system’s water source. A number of these nutrient solutions are liquid; however, they may also be found in water-soluble powder forms.

Whether you create your own nutrient solution in the different mosquito bites or purchase a brand new brand, problems can, an often do, arise with deficiencies of one or more of the nutrient components.

Frequent causes of this are that (1) the nutrient potency might be too low, leading to generally insufficient nutrients for the plants. (2) The nutrient formula you’re using may not be completely balanced, and one (or more of those components ) may be deficient. (3) Sometimes, growers may unintentionally leave out among the fertilizer salts, or the incorrect fertilizer was used when the nutrient formulation was weighed out.

And to complicate matters further, even if your answer is nicely balanced, sometimes internal and environmental conditions of the palnt, prevent the uptake of certain nutrients and lack symptoms then result.

Can I Create My Own Hydroponic Nutrients?

Purchasing pre-made hydroponic nutrients is undoubtedly the simplest way to maintain your indoor garden well hydrated. Still, you can also mix your hydroponic nutrients to customize the nutrient levels and have complete control over what you are feeding to your crops.

The main issue is to understand the requirements of your particular garden before starting. As soon as you know precisely what minerals should be on your nutrient solution, you can get to work.

A hydroponic nutrient solution is made up of water, essential elements, and minerals. It is possible to use fertilizer salts to obtain the majority of these elements. When mixing your answer, you will need to look into the ratios required for the particular plants you are growing, and the nutrient potency (PPM) you may need.

Concocting your nutrient solution can be somewhat complicated, so for those new to hydroponics, it is usually best, to begin with pre-made solutions; otherwise, you might be endangering the lives of your plants.

Understanding which fundamental nutrients all plants will need to survive will permit you to understand how and why hydroponic nutrients work. Knowing your indoor garden’s specific nutrient needs can allow you to decide on which sort of hydroponic nutrients you need to use.

Having a basic notion of your plants’ life cycles will also help you understand when to use grow certain nutrients and when to utilize nutrients designed to optimize their blossom.

What Must Hydroponic Fertilizers Contain?

To ensure that your plants receive all they need, these components should be in the fertilizer you decide to buy. It must be noted that there can be different kinds of fertilizer for different plant types; therefore, levels of certain nutrients will be lower or higher, and typically, this will be the N, P, K ratios which differ.

Both of these lists cover the vital elements of what has to be included.

■ Nitrogen (N)
■ Phosphorus (P)
■ Potassium (K)
■ Calcium (Ca)
■ Sulfur (S)
■ Magnesium (Mg)
■ Iron (Fe)
■ Manganese (Mn)
■ Boron (B)
■ Zinc (Zn)
■ Copper (Cu)
■ Molybdenum (Mo)


The optimal pH range of the hydroponic nutrient solution is 5.8-6.3. Micronutrients are a more accessible lower pH, but if pH levels fall below 5.5, you run the risk of micronutrient toxicity, in addition to impaired access to calcium and magnesium.

In hydroponics, particularly in closed systems, the roots easily influence the hydroponic solution pH so that pH will fluctuate.

Suitable products for acidifying the hydroponic nutrient solution are sulfuric acid, phosphoric acid, and nitric acid.

Ammonium/nitrate is among the most significant factors affecting the pH of the nutrient solution.


With all the info above, you can see that choosing a proper hydroponics fertilizer is crucial for plants to grow as they should.

one final thing to mention again, a typical fertilizer can radically raise or reduce your pH levels, whereas bought fertilizers or nutrients explicitly intended for hydroponics often arrive with pH buffers built-in.

Regular fertilizers are an “all in one solution”, but as we know, there are no all in 1 solution in regards to hydroponics. To get the best out of our crops, we will need to supply them with the very best of what they desire, and picking a fantastic liquid nutrient solution will help prevent all the issues above from using fertilizer.
