    The Ultimate Vapor Pressure Deficit (VPD) Guide

    "Why devote an entire guide to VPD?" you might ask. The answer is that the vapor pressure deficit (VPD) is extremely important for growing plants.

    VPD helps you identify the correct range of temperature and humidity to aim for in your grow space. With VPD you can achieve the best results while avoiding pest and environmental problems. VPD also controls plant transpiration rates, stomata opening, CO2 uptake, nutrient uptake, and plant stress.

    If you master VPD, you master your environment, and become a better grower.

      I find it strange that in the VPD chart on the x axis 0 is on the right and on the y axis lower numbers are on top.
      Both axes should be the other way around.
      But the story as a whole is very interesting.
      Thank you.
