What is Hydrogen Peroxide?

Hydrogen peroxide is a chemical compound with the formula H2O2. It is a common chemical used in hydroponics systems as a sanitizer and oxygenator.

Uses of Hydrogen Peroxide in Hydroponics


H2O2 can be used to kill off harmful bacteria, fungi, and other pathogens that can contaminate a hydroponics system. By regularly sanitizing the system with H2O2, hydroponics growers can help prevent the spread of diseases and infections that can harm the plants


It can also be used to increase the amount of oxygen in the nutrient solution, which can be beneficial for the plants. Oxygen is essential for plant growth, and H2O2 can help provide an extra boost of oxygen to the plants, promoting healthy growth and development.

Pest Control

Hydrogen peroxide can also be used as a natural pest control solution in hydroponics systems. When applied to the plants, H2O2 can help kill off pests such as aphids, mites, or bacteria which can damage the plants and reduce crop productivity.

Algae Control

It can help kill off algae and other aquatic organisms, making it a useful tool for controlling algae growth in hydroponics systems. It is generally recommended to use a 3% concentration of H2O2, which can be added to the nutrient solution or sprayed directly on algae.

Overall, hydrogen peroxide is an important tool for hydroponics growers to have in their toolkit. It is safe and effective at improving the health and growth of plants, and it can also help to prevent diseases and pests from harming plants. By using hydrogen peroxide in their hydroponics systems, growers can help to ensure that their plants are healthy and productive.
