Algae growth is actually made up of several different types of plant-like organisms. Since there are many different types of algae growth, its appearance in your hydroponic system can take a few different forms.
Algae may be slimy, bubbly, fury, or stringy and may appear in different colors including green, brown, red, and black. Since algae thrive in the same conditions as plants, a hydroponic garden is an ideal environment for algae growth. Here are three things you want to know about algae growth in your hydroponic system.
How Does Hydroponic Algae Growth Start?
Algae in your hydroponic garden start from microscopic spores that are transported through the air. There are steps you can take to reduce the levels of contamination, but it’s hard to prevent algae spores from reaching your system.
Since algae are plant-like, your hydroponic system can be the best environment for algae growth. Warmer temperatures, nutrients, water, and light are what algae needs to grow. Light reaching hydroponic-rich water starts the growth of algae. Once it starts, algae spread and can reproduce rather quickly.
Is Algae Growth Harmful To A Hydroponic Garden?

Algae will steal the oxygen from the plant’s root system, affecting respiration, and causing your plants to weaken.
How Do You Get Rid of Algae In Your Hydroponic System?
The best way to stop algae growth is taking away at least one element it needs to grow. By removing its source of light or reducing the amount of nutrients exposed to light, algae will not be able to grow. Finding something that will rid your system of algae and not harm your plants is a challenge. Since algae are plant-like, often what is harmful to algae is harmful to your garden.
