What are hydroponic nutrients?

The term hydroponics is derived from two Greek words hydro meaning water and ponic meaning plants. A hydroponic system is a system where plants are grown without soil. Where will the plants get nutrients from? That’s where hydroponic nutrients come in.

So, what are hydroponic nutrients? These are commercially made plants nutrients specifically for plants grown without soil.

Benefits of a hydroponic system

  • Easy to provide nutrients- when plants are grown in soil, the nutrients can be leached beyond the reach of the plant roots. This means that the plants will be starved of nutrients. The same case cannot be said about a hydroponic system. The nutrients are provided directly to the plant roots.
  • Can be used indoors and outdoors- the popularity of indoor farming has increased over the years. The hydroponic system can be used both indoors and outdoors which is an added advantage.
  • It is economical- we are living in hard times. Any opportunity we get to save on a few dollars we should take it. Using a hydroponic system is economical in the sense that plants are grown in a controlled area and there is less need for pesticides.
  • Saves time- plants grow in a controlled area are easy to monitor. Growing plants through a hydroponic system help save time in the sense that it is easy to monitor the plants.

Factors to consider when purchasing the best hydroponic nutrients

Easy to use

Some brands have everything mixed for you. All you need to do is add water to dissolve the nutrients then administer to your plants. Given that hydroponic is a relatively know tech and most people are not well conversant with it, as a beginner it is recommended that you choose a brand that is easy to use.

Hydroponic nutrients are available in two forms that are liquid and dry powder. For a beginner, liquid form is the most recommended choice given the fact that it’s easy to use. However, it’s more expensive than dry powder hydroponic nutrients.

Powder hydroponic nutrients, on the other hand, require some skills to mix but are considered economical and suitable for large plantations. Powder hydroponic nutrients are also fit to use in greenhouses.

Organic vs synthetic

The best and most recommended farm practice is organic farming. There are both organic and synthetic hydroponic nutrients with each having its own set of advantages and disadvantages. The best organic hydroponic nutrients are chemical free meaning that these chemicals won’t end up to your plants and cause serious health complications. The only drawback with organic hydroponic nutrients is that they leave a foul smell and have low solubility.

On the other hand, synthetic nutrients contain chemicals some of which can be toxic. Synthetic hydroponic nutrients are highly soluble in water and relatively affordable.

Plants to be grown

Different plants require different nutrients at different stages of growth. To ensure that you only purchase what will be best for your plants go check on the nutrients content on the product label. Before then you should have researched on the nutrient requirement of the plants that you are growing. This is easy since all this information is available online or you can consult a specialist just to be sure. For plants to yield more they must get all the nutrients they require.

PH is also a key factor when it comes to plants. Some plants thrive in slightly acidic conditions whereas most do well in a neutral to base PH. The PH levels of the nutrient solution should be indicated on the product label. Check to see if it suits your plants.


You can’t purchase what you can’t afford and expensive doesn’t always guarantee high quality. In our review, we have mixed up things by reviewing both the expensive and affordable hydroponic nutrients to cater for the various spending capabilities. There is no recommended price tag you should be on the lookout for. Just review the features and determine what’s best for you based on what you can afford.

The Best Hydroponic Nutrients Must Have the Following Set of Macronutrients

Plants require Potassium, phosphorus, and nitrogen in large quantities and for this reason, you should always check to confirm that all the three are available. Each nutrient is essential for the growth of plants performing the following roles:


Nitrogen is essential for the growth and development of leaves. It is nitrogen that helps in the formation of the green pigments responsible for carrying out photosynthesis. A deficiency in nitrogen will hinder the vegetative growth of plants even worse make the leaves turn yellow.


For the development of healthy stems, roots, and flowers, your plants need phosphorus on large in large quantities. Sufficient supply of phosphorus ensures both quality and quantity buds/flowers.


This nutrient is essential for the overall growth of plants and in particular, synthesis of proteins.

Using Hydroponic Nutrients with Success

Hydroponic nutrients are supposed to increase the yields of your plants. But, you must first learn how to do it right. As mentioned earlier hydroponics is the science of growing plants without soil. Nutrients and minerals have to be dissolved in water for them to be availed to the plants.

Always ensure that you follow the instruction on the product label. The concentration should be as recommended. Too much of it might make the solution acidic and this will damage your plants. The recommended percentage of the three macronutrients that is Nitrogen, Potassium and Phosphorous is 15%, 30%, and 30% respectively.

  1. I am using General Hydroponics Flora Grow, Bloom, micro-Combo Fertilizers in an OUTDOOR hydroponic system. The plants are not really thriving and leaves are yellowish at times. I was following the label dosage and then backed off fearing I was giving too much. Plants are veggies ranging from peas to lettuce, beans, tomatoes.
