Managing Algae Growth in Your Growcer Farm

Identifying, Managing, and Preventing Algae Growth in Hydroponic Systems

Overview 

Algae growth is a common occurrence in Growcer farms, particularly in nutrient solutions and growing areas. While some algae can be beneficial, excessive growth can pose challenges to plant health and system efficiency. This article outlines how to identify and manage algae growth effectively. 

Types of Algae Growth 

  • Normal Algae Growth
    • Algae can naturally occur on seedling rockwool cubes and in the growing environment. This growth is generally manageable and not harmful if kept in check. 
  • Excessive Algae Growth
    • When algae growth becomes excessive, it can lead to problems, such as reduced oxygen levels in the nutrient solution and potential competition for nutrients. 

Troubleshooting Algae Growth 

  1. Algae Growth in Seedling Area
    1. Check the Seedling Pump Timer: 
      1. Ensure that the timer is functioning correctly. 
      2. The pump should be set to run for 2 minutes per day. 
  2. Algae Growth in Main Growing Area
    1. Monitor and Observe: 
      1. Continuously monitor the algae situation, taking notes on its progress and any changes. 
    2. Minimize Light Exposure: 
      1. Advise customers to reduce the amount of light reaching the nutrient solution to inhibit algae growth. This can be achieved by: 
      2. Avoiding gaps in the runways. 
      3. Refraining from placing empty rafts on the runways, as algae can develop around unoccupied slots. 
  3. Use Panda Film Sheets: 
    1. Consider using panda film sheets to block light from empty spaces on the runways. 
  4. Clean Affected Areas: 
    1. Clean areas where algae is present to help control its growth. 
  5. Full Sanitation: 
    1. If algae levels are high, a complete sanitation of reservoirs and runways is necessary. Follow SOP Regular Maintenance & Operations.  

Information Gathering 

When communicating with your Growcer Support Team, please provide detailed information to aid in troubleshooting: 

  • Location of Algae: Where is the algae primarily found? 
  • Date Discovered: When was the algae first observed? 
  • General Observations: Any notable changes or conditions related to the algae growth. 
  • Additional Information: Any other relevant details that could assist in diagnosis. 

Communication and Support 

Communicate any issues with the Farm Support and Training Technicians to develop a plan of action. In some cases, water samples may be required for pathogen and nutrient testing to ensure a comprehensive approach to managing algae growth. 

Conclusion 

By understanding the nature of algae growth and implementing proactive management strategies, you can maintain a healthier growing environment in Growcer farms. For further assistance or specific inquiries, please consult help@thegrower.ca
