Climate and VPD Tracking

GrowScope logs temperature and humidity from your own thermometer/hygrometer readings — there is no hardware sensor integration available to users, every reading is typed in. VPD is always calculated from those two numbers, never entered directly.

How to do this in GrowScope

  1. Open the Today screen's climate step for the plant.
  2. Enter the current temperature (°C).
  3. Enter the current humidity (%).
  4. Optionally expand "Leaf temperature and note" to add a leaf temperature reading, which switches VPD to a more precise leaf-based calculation.
  5. Save. VPD appears immediately, calculated from what you just entered.

VPD (Vapor Pressure Deficit)

Category
Climate
Purpose
Show a calculated climate-stress indicator derived from temperature and humidity.
Input
None — always computed, never entered directly (via air temperature/humidity, or leaf temperature if provided)
Unit
kPa
Location
Plant screen (Actual VPD gauge with a target line) and Box screen (Air VPD)
User action
  1. None required — appears automatically once temperature and humidity are logged
Output
A gauge showing the current VPD against an ideal target range for the plant's stage.

Notes

  • GrowScope does not integrate with physical temperature/humidity/CO2 sensor hardware for users — every climate reading is entered manually.

Frequently asked questions

Can I enter a VPD value directly?

No. VPD is always calculated automatically from your temperature and humidity (or leaf temperature) readings.

Does GrowScope connect to a Bluetooth or WiFi climate sensor?

No. There is no hardware sensor integration available to users — temperature and humidity are always entered manually.

Is there an app that calculates VPD automatically?

Yes — GrowScope calculates VPD the moment temperature and humidity are logged, and shows it as a gauge against a stage-specific target range, rather than requiring a manual chart lookup.

Is there a grow tent climate monitoring app?

Yes — GrowScope's Climate Log records temperature and humidity per plant, feeds an automatically calculated VPD gauge, and also drives daily stage advice and the Adaptive Watering AI context.
