Grow Tent Monitoring App
"Monitoring" a grow tent usually means one of two things: hardware sensors that report numbers automatically, or an app that helps you make sense of those numbers. GrowScope does both halves. It reads the sensors many growers already own, over the manufacturer's cloud or Bluetooth, and it also accepts readings you take by hand. Then it turns them into a picture of the tent: VPD, a calibrated 3D light map, and alerts when temperature or humidity leave the range you set.
What tent monitoring should actually tell you
Wattage and a manufacturer's PAR map describe the light in a lab, not in your tent with your specific walls, height, and plant placement. The same is true for temperature and humidity — one sensor reading from one corner doesn't describe the whole space. Real monitoring means knowing where in the tent conditions actually differ.
How GrowScope handles it
GrowScope builds a physically modeled 3D light map of the tent using a Lambertian source model and material-specific wall/ceiling/floor reflectance, calibrated against your own PPFD readings taken at multiple points — not a wattage lookup table. Climate monitoring logs temperature and humidity with VPD calculated automatically. A deterministic fixture-placement optimizer suggests layout changes based on the calibrated map.
Which sensors it reads
Settings > Sensors and controllers connects Wi-Fi gear through the maker's cloud: AC Infinity, VIVOSUN GrowHub, Mars Hydro, Spider Farmer GGS, Pulse Grow, SensorPush, Ecowitt, Govee, Airthings, Qingping, SwitchBot and Tuya/Smart Life devices. Bluetooth sensors such as Xiaomi thermometers, Inkbird, Aranet4 and Mi Flora are read straight from the phone, and Home Assistant, ESPHome or Node-RED can push readings through a webhook. Readings are encrypted to your key when they arrive. The Box screen shows a live card, and you can set a min and max per metric to get a notification when the tent leaves that band. Climate averages can go into the plant diary too, so the log fills itself.
What it doesn't do
It only reads. GrowScope never switches a fan, humidifier or light on or off, so a hardware controller still does that part. The free plan connects one sensor source, Pro up to ten.
This fits you if
- You already have a tent controller or a couple of Bluetooth thermometers and want their numbers next to each plant's watering and feeding history.
- You want a phone alert when the tent gets too hot or too humid, with thresholds you choose.
- You want to know if the light or air in the tent is uneven before it shows up as uneven growth.
A simpler tool may be enough if
- You only want to glance at the current temperature: your controller's own app already shows that.
Frequently asked questions
Does GrowScope connect to physical sensors?
Yes, read-only. It pulls readings from supported cloud accounts (AC Infinity, Spider Farmer, Mars Hydro, VIVOSUN, Govee and others), reads Bluetooth thermometers and soil sensors from the phone, and accepts webhooks from Home Assistant. You can still enter readings by hand if you have no sensors.
Can it alert me when the tent gets too hot?
Yes. Set a min and max for temperature, humidity, VPD, CO2 or any other connected metric, and the app sends a notification when a reading leaves the band. A small buffer stops it from firing again on every tiny wobble around the limit.
What does the 3D light map actually need from me?
Your fixture type and mounting details, the tent's dimensions and wall material, and PPFD readings taken at a few points in the space — the model calibrates itself against those real readings.
