VPD Chart 12+

Vapor Pressure Deficit (VPD) chart and calculator for controlled environment horticulture. Automate with sensors. Cannabis, tomatoes, leafy greens, cucumbers.

The app calculates VPD utilizing air temperature, air RH, and canopy temperature, generates the chart and displays the VPD value on it. Connect sensors seamlessly for automated readings, or manually input data via intuitive sliders / text inputs.

Key features:
• Select your crop type from: cannabis, tomatoes, leafy greens, cucumbers
• Define an unlimited number of charts
• Organize and your growing areas by assigning specific charts to different zones
