Why it’s recommended to have hydroponic nutrients

1. Improvement of environmental tolerance

What makes these hydroponic nutrients important in the overall welfare of your plants is that they improve their tolerance.

What we mean by this is that they become stronger and become more tolerable of the changes happening in their environment.

They don’t easily wither or die if the temperature changes or if you’ve skipped watering them. Your plants become tougher in the process.

2. Longer lifespan

What happens when your plants become tougher?

Well, they have a longer lifespan. The likelihood of them withering or dying out decreases to a minimum because they have a stronger body frame.

This gives you the chance to make the most out of your plants and yield every single fruit or vegetable from them.

3. Bigger and blooming features

The plants inside your hydroponic system become bigger, stronger, and taller. These hydroponic nutrients make your plants bloom and be in their best form.

It’s because of this that your plants don’t serve a functional purpose, but they also become more appealing and attractive looking.

So if you want to make the plants in your hydroponic system serve an aesthetic purpose, using hydroponic nutrients is the best way to go.

4. Economical

Using hydroponic nutrients on your hydroponic plants is also an economical way to take care of your plants. You don’t need to spend money on countless different types of fertilizers or herbicides.

It’s because all of the vitamins and minerals are already present in the hydroponic nutrients that you’re giving to your plants.

Elements that a good hydroponic nutrient should have

1. Nitrogen

If you’re searching for a good hydroponic nutrient, make sure that it has nitrogen.

Nitrogen is very important because it is the one that enables your plants to have more energy. Energy is needed because it is the one that helps your plant to bear more fruit or to generate more stems and leaves.

2. Potassium

Potassium is an essential component of hydroponic plants because it activates the enzymes in your plant.

It’s because of this that your plant is better capable of producing more Adenosine Triphosphate, which is a vital source of energy for the many chemical processes your plant undergoes.

3. Phosphorous

Phosphorus is highly needed by your hydroponic plants because this is what stimulates their root growth and development.

Aside from that, it also helps strengthen their stems and stalks and improves seeding and flowering formations.

Overall, supplying your plant with phosphorus leads to better crop quality.

4. Calcium

Also, make sure that the hydroponic nutrient you’re getting contains a lot of calcium.

Calcium is the one that enables your plant to have better metabolic processes. It’s through this that the plant gets a stronger cell wall structure, thanks to the calcium component formations on its body.

5. Chlorine

You should also make sure that it has a fair amount of chlorine, as this is what neutralizes the plant’s microbes and other unhealthy microorganisms. It is what cleans up your plant’s living environment. 

Chlorine is the one that disinfects your plant.

Hydroponics nutrients buying guide

1. Which one to choose? Liquid or powdered hydroponic nutrients

A bottle of nutrient solution or liquid hydroponic nutrients can be easily mixed with water and doesn’t take much time to get used to.

However, it is costly for shipping and storage because of the heavy weight of the product.

Solid fertilizers or powdered hydroponics nutrients are only suitable for the experienced farmer because they are sophisticated to mix. Yet, they don’t make much money when being shipped.

To summarize, if you take gardening as a hobby, a bottle of liquid nutrients will suit you best due to its simplicity.

Whereas, for companies and farmers working in the agricultural industry, a pack of solid fertilizers is an optimal choice owing to the low price and reliable quality.

2. Synthetic or organic hydroponic nutrients

Thanks to the advances in technology, the agricultural industry has many breakthroughs in the production of fertilizer. Many manufacturers have found an excellent formula for their hydroponics nutrients.

The organic nutrient is the term used for elements of fertilizer that are exploited by nature. On the contrary, a synthetic nutrient is a kind of artificial fertilizer that is formed through the experiments and research of professionals.

If you use a pack of organic nutrients, you can be sure of its quality and purity. Nonetheless, you won’t know precisely the ratio of each mineral that is necessary for vegetative growth.

With synthetic nutrients, you will definitely know the exact amount of each mineral. However, in some cases, the chemicals in the nutrients may negatively react with your plants.

To conclude, synthetic hydroponics nutrients will be a better option. Why? Because of the thorough examination of many scientists, the nutrients vital for your crops can be delivered punctually in any growth stage.

As a result, there will be a more productive outcome.


How long do hydroponics nutrients last?

Typically, nutrients can last from 7 to 10 days, depending on your draining, cleaning, and remixing of your nutrients.

How often should you add nutrients to hydroponics?

The best time for you to add nutrients to hydroponics will vary. Sometimes, it is a period of 2 to 3 days, but you can do it daily.

Can you use hydroponic nutrients in the soil?

The answer is: Yes, you can.

But, you would like to bear in mind that the ratio of hydroponic nutrients is really important. If you feed your plants with too many nutrients, they won’t grow fresh, or they can even be dead.

We have provided you with the top 8 best hydroponic nutrients. All of them are high-quality products from many agricultural processes. Yet, if we have to pick the best one of them, it’s going to be the set of three General Hydroponics Flora Grow, Flora Micro, and Flora Bloom.
