Description
Welcome to the Dr. Greenhouse VPD App!
With this tool, you can easily calculate the Vapor Pressure Deficit of your grow room’s air.
First, choose your temperature units: Fahrenheit or Celsius. Then plug in the air temperature and relative humidity and click “Calculate.” The resulting VPD (kPa) will be color-coded to indicate whether the grow room climate is humid (blue), vegetative (green), reproductive (yellow), or dry (purple).
The desired VPD depends on the type of plant, its stage of growth, and, in some cases, the time of day. In general, leafy greens, microgreens, and other non-flowering plants enjoy a “vegetative” environment. Flowering and fruiting plants benefit from a “reproductive” environment. Cannabis plants may yield more trichomes and terpenes, if exposed to a “dry” and water-stressed environment in the days leading up to harvest. And a “humid” nighttime environment can improve translocation of nutrients and metabolites to strawberries and other fruiting plants.

Ratings and Reviews
Best Calculator in the App Store
If all you need to know, is a simple calculation of your VPD this app is perfect! It has an easy switch to calculate Fahrenheit and Celsius so there’s no need to guess and, it also tells you the best VPD limits for each stage of your plants that actually lines up with everything that I’ve ever seen online
Easy to use and make changes
The VPD app is great for on the fly / in the field calcs to ensure I have the best environment for plant growth. So long paper chart!
Great indoor farming calculator
Easy to use on the fly, and I like that it has charts for different crops.
