VPD chart, grow diary, and smart automation for Tuya, Mars Hydro, AC Infinity, Spider Farmer, Vivosun, Bluelab & SANlight — all in one app. No sign-up, no bloat.
Three core tools. One free app. Zero compromise.
Interactive heatmap with color-coded zones for each growth stage. Leaf temperature correction, dew point calculation, live Bluetooth sensor support.
Seed to harvest. Photos, pH, EC, PPFD, nutrients, harvest stats. Compare multiple grows side by side.
Connect Tuya, Mars Hydro, AC Infinity, Spider Farmer, Vivosun, Bluelab & SANlight in one system. Mix brands freely — use a Tuya sensor to trigger your Mars Hydro fan, control Tuya AC units directly (dehumidify, cool, heat, ventilate). No other grow app does this.
Most devices use internet (WiFi or mobile data) & cloud APIs. SANlight connects via Bluetooth. Everything else in the app works fully offline.
Offline reference for 30+ diseases, deficiencies and pests with symptoms and treatment guides.
Designed for growers, by a grower
Most growers mix equipment from different brands. Their apps don't talk to each other. GrowVPD Pro connects them all.
Create custom light plans with sunrise & sunset simulation — your lights gradually ramp up in the morning and dim down at night, just like the real sun. Set precise on/off times (18/6 for veg, 12/12 for flower), configure sunrise duration (15–120 min ramp-up), sunset duration, and peak brightness (5–100%). Save multiple named plans (Seedling 40%, Veg 80%, Flower 100%) and switch between them with one tap. Enter times via slider or manually type HH:MM for precision. Control Mars Hydro, Spider Farmer & Vivosun LEDs from one place — each light gets its own independent schedule.
Tuya sensor detects VPD above 1.5 kPa — app automatically turns on your Mars Hydro inline fan to bring humidity down. Fan speed adjusts proportionally — small deviation = low speed, big deviation = full power.
Temperature drops below 18°C at night? Your heater on a Tuya smart plug kicks in automatically.
AC Infinity controller reads CO2 below 800 ppm — your CO2 generator on a Tuya plug turns on. Different brands, one rule.
Humidity above 65% during flowering? The app connects directly to your Tuya-compatible AC unit and switches it to dehumidify mode. No smart plug needed — the app controls your air conditioner natively. Dehumidify, cool, heat, or ventilate with a single rule.
Temperature rises above 28°C? The app switches your Tuya AC to cooling mode and ramps up the Mars Hydro inline fan — simultaneously. One sensor, two devices, two brands, fully automatic. Your AC is a native Tuya device, controlled directly without any adapter.
Tuya soil moisture sensor reads below 40%? The app triggers your Tuya-connected irrigation valve or pump automatically. Perfect for coco, autopots, and drip systems. Combine with soil temperature & EC sensors for complete root zone automation.
Running autopots or a reservoir system? A Tuya water level sensor monitors your tank. When the level drops too low, the app sends you an alert and stops the pump — preventing dry runs and protecting your plants. Ideal for autopot, DWC, and ebb & flow setups.
Sensor readings (temp, humidity, VPD, PPFD, CO2) are logged to your grow diary every 15 minutes. Camera snapshots too. Your diary fills itself.
Tuya, Mars Hydro, AC Infinity (beta), Spider Farmer (beta), Vivosun (beta), Bluelab (beta), SANlight (beta)
VPD, temperature, humidity, CO2, PPFD, soil moisture, soil temperature, soil EC, water level, and more. All with hysteresis and safety limits.
Every integration is validated through a complete real growing cycle — not just on a bench. We spotted a widely-reported Mars Hydro connection issue, traced it to the protocol level, and fixed it. Your devices don't disappear between grows.
Smart automation requires internet (WiFi or mobile data) — devices are controlled through their manufacturer cloud APIs (Tuya Cloud, Mars Hydro MQTT, etc.). All other features in the app work fully offline.
No other grow app lets you combine devices from different manufacturers into one automation system.
