VPD in Hydroponics: Maximizing Growth Potential

Vapor Pressure Deficit, or VPD, is a crucial factor in hydroponic plant growth. By understanding VPD and learning how to calculate it, growers can optimize their hydroponic systems to achieve maximum growth potential. In this section, we will explore the importance of VPD in hydroponics and how to calculate it accurately.

Key Takeaways:

  • VPD, or Vapor Pressure Deficit, is a measure of the air’s ability to accept moisture in hydroponic systems.
  • Understanding and controlling VPD can optimize plant growth by affecting stomata opening, CO2 uptake, transpiration, and nutrient uptake.
  • Calculating VPD involves measuring temperature, humidity, and using specific formulas or visual guides like VPD charts.
  • VPD requirements vary across different stages of plant growth, and it is essential to understand the ideal VPD range for each stage.
  • VPD at night is also crucial for maintaining optimal plant health, and different VPD ranges are recommended for different growth stages.
