Diagnosing Poor Germination Issues

Comprehensive Steps for Assessing and Diagnosing Poor Germination in Hydroponic Systems

Overview 

Poor germination can arise from various factors, including organic, mechanical, or physical issues. This article provides a comprehensive guide to assessing, analyzing, and diagnosing poor germination in hydroponic systems. Detailed information from you is crucial for effective troubleshooting. 

Factors Contributing to Poor Germination 

  1. Organic Factors
    1. Sanitation Practices: Assess the cleanliness of the growing environment. 
    2. Plant Material: Evaluate the quality of seeds and other plant materials used. 
    3. Nutrients: Ensure that nutrient levels are adequate and balanced. 
    4. Pathogens: You may be required to test for any potential pathogens that could impact germination. 
  2. Mechanical Factors
    1. Growing Unit and Components: Inspect the functionality and condition of the growing unit and its components. 
  3. Physical Factors
    1. Practices and Procedures: Review the methods used for seeding and caring for the seedlings. 

Information Gathering 

To assist with diagnosis, customers are asked to provide detailed information and photos related to the germination issue. Use the following questions to guide the conversation: 

General Information 

  • Sanitation Practices: 
    • When was the last cleaning of the seedling area, tank, and tray? 
  • Seeding: 
    • Describe the seeding process used and any deviations from standard practices. 
  • Growcer Unit Environment: 
    • Check the environmental data via Growlink to assess the climate conditions. 

Cultivar Impact Assessment 

  • Were multiple cultivars affected, or was the issue isolated to one specific cultivar? Please provide photos for reference. 

Extent of Impact 

  • What percentage of the plants were affected, and what is the germination percentage among the affected plants? 

Environmental Conditions 

  • Provide information on temperature and humidity levels in the growing environment. Have there been any notable fluctuations? 

System Issues Check 

  • Are there any pre-existing issues with the growing system that could contribute to the problem? 

Seeding Area Conditions 

  • Are there any imbalances or dry spots in the seeding area? 

Water Flow Assessment 

  • Is there adequate water flow through the seedling table, or is there excess water accumulation? 

Lighting Inspection 

  • Are the lights above the seedling table functioning properly? 

Nutrient Levels 

  • What are the EC (Electrical Conductivity) and pH levels in the seedling area? 

Seed Age and Storage Conditions 

  • What is the age of the seeds, and how are they being stored? 

Humidity Tray Usage 

  • Were humidity trays used until day 7 after seeding to maintain optimal humidity levels? 

Observation of Seed Issues 

  • Have there been any observations of mold or other issues on the seeds prior to planting? 

Additional Testing 

  • Water samples may be required for pathogen and nutrient testing. Note that the cost of the water samples will be the customer's responsibility. In rare cases, the costs can be covered internally after discussion. 

Seed Viability Information 

  • Some seeds can remain viable for several years if stored under optimal conditions (low humidity and low temperature around 15°C). 
  • Germination rates and seed viability can decline with age; however, viability typically decreases before germination rates.
