What is Algae?
Algae is a type of plant-like organism that can be found in water. It is often green in color, but can also be brown or red. It needs sunlight, water, and nutrients to grow.
Common Problems with Algae in Hydroponics.
Algae is a common problem in hydroponics systems, as the presence of light, water, and nutrients can create an ideal environment for algae growth. Algae can interfere with the growth and health of the plants by competing for light, water, and nutrients, and can also lead to reduced water quality and clogged irrigation systems.
Here are a few specific problems that algae can cause in hydroponics systems:
Nutrient competition
Algae can absorb nutrients from the nutrient solution, which can reduce the availability of nutrients for the plants. This can lead to nutrient deficiencies and reduced plant growth.
Oxygen
depletion
Algae can consume oxygen from the water, which can lead to oxygen depletion in the system. This can be especially problematic for plants, as they require oxygen for proper growth and development
Water quality issues
It can contribute to the build-up of organic matter in water, which can lead to reduced water quality and increased bacterial growth. This can be harmful to the plants and can also lead to clogged irrigation systems.
Aesthetically unappealing
Algae can also make the hydroponics system look unappealing, which can be a problem for growers who are using the system for ornamental or decorative purposes.
How to Avoid Algae in Hydroponics?
Prevention is Better Than Cure!
Prevention is Better Than Cure!
As discussed earlier, algae needs sunlight, water and nutrients to grow. Avoiding sunlight can greatly reduce the formation of algae in hydroponic systems. Keeping the tanks in shade or using black tanks, covering empty grow spaces can help in preventing algae formation. At City Greens we have "2 inch Black Net-pot Covers" that can be used to cover any empty grow space created after harvesting or removing any diseased plant.
Using Hydrogen Peroxide
H2O2 is a chemical that 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 onto the algae. Using H2O2 in large quantities can also be toxic to plants. Therefore, to is important to use in recommended quantities and follow manufacturer's instructions.
In addition to above methods, there are other measures that can be taken to reduce algae growth in hydroponics systems, such as increasing the circulation of the nutrient solution, and maintaining proper pH and nutrient levels. By implementing these strategies, hydroponics growers can help prevent algae formation and promote healthy plant growth in their systems.
