Know your VPD in seconds.
Enter temperature & humidity (or tap the interactive heatmap) to see Leaf VPD and Air VPD with scientifically labeled isolines. Choose Seedling / Veg / Flower / Late Flowering to see target VPD ranges and how best to nudge your environment to “ideal.”
Why growers love it
• Interactive heatmap: drag to explore temperature–humidity combos
• Stage presets: recommended VPD bands by plant development stage
• Leaf vs Air: leaf–air offset, dew point, absolute humidity
• Beautiful widgets: small/medium/large Home & Lock Screen widgets
• Private by design: on-device calculations, no account required
Details
• VPD = es(T) × (1 − RH/100); leaf VPD uses leaf temperature (air + ΔT)
• Absolute humidity via water vapor partial pressure (ideal gas law)
• Full support for °C/°F, metric/imperial
• Export logs to CSV
