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 improved 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 which 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 which 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 heavyweight of the product.
