Best values to run in your tent?

New to all this. Have a vague understanding of vpd but don’t know how to controller or “ fine tune” it?

Hi Tommy,

You control vpd with temperature & humidity (from

  1. Temperature
  • Increase temperature (run a heater or reduce AC): increase VPD
  • Decrease temperature (increase AC): decrease VPD
  1. Humidity
  • Increase humidity (run a humidifier): decrease VPD
  • Decrease humidity (run a dehumidifier): increase VPD
