Real-time VPD, temperature, humidity, CO₂, pH & EC monitoring for every plant you grow — with AI diagnostics and 24/7 automated alerts. Works for tomatoes, herbs, vegetables, fruits, and cannabis in any grow tent or room.
GrowAI was designed from the ground up for precision indoor growing. Every metric, every alert, every AI recommendation is tuned to what your plants actually need — by growth stage and plant type.
GrowAI calculates vapour pressure deficit (VPD) in real time from your temperature and humidity sensors. Stage-specific VPD targets auto-adjust for seedling, veg, and flowering across every plant type. Try VPD calculator →
Track daily light integral (DLI) and lux levels for every grow tent or room. Know exactly how much light your plants are receiving and when to adjust for optimal growth.
Tag every plant with its current stage — seedling, veg, early flower, late flower, or harvest. Optimal environment targets and nutrient EC ranges update automatically for each plant type.
Monitor pH and EC/TDS nutrient strength live. HarvestBot flags lockout risks and deficiencies before they cost you yield — with targets calibrated for each plant and stage. EC calculator →
Most veg rooms want 70–82°F at 50–70% RH. Fruiting rooms typically need 65–80°F at 40–55% RH. GrowAI alerts you the moment your room drifts — day or night. Ventilation guide →
Running a veg tent, a flower tent, and a clone room? GrowAI manages all of them from one dashboard. Separate sensor zones, separate thresholds, one app.
From the first seed to final harvest — GrowAI keeps your data organized, your plants healthy, and your operation running without constant manual checks.
Temperature, humidity, VPD, pH, EC, CO₂, light intensity and more — updated every 30 seconds directly from your GrowAI Hub.
Ask HarvestBot anything about your plants. It reads your live sensor data and plant profiles to give precise, actionable advice tailored to your specific grow.
Track every plant by variety, growth stage, planting date, nutrient schedule, and health history. Supports tomatoes, peppers, herbs, vegetables, fruits, and any hydroponic crop.
Set min/max ranges for any sensor. Get instant alerts the moment VPD, temperature, humidity, CO₂, pH, or EC falls outside your target zone.
Manage multiple grow rooms, tents, or facilities from a single dashboard. Each environment has its own sensors, plants, and history.
Plug-and-play setup with your GrowAI Hub. Pair in under two minutes using a secure QR code — no networking knowledge required.
A look inside the GrowAI environment dashboard — every sensor reading updated in real time, from anywhere in the world.
Your personal grow AI. Ask questions, get diagnoses, and receive recommendations — all grounded in your actual live sensor readings and plant data.
Create detailed profiles for every plant variety or hydroponic crop — track growth stage, nutrient schedule, VPD targets, pH, EC, and health history all in one place.
GrowAI is designed so that any indoor or hydroponic grower — beginner or expert — can get live sensor data flowing in under five minutes. No networking degree required.
Plug in your GrowAI Hub, scan the pairing QR code, and it's linked to your account automatically.
Set up grow rooms, tents, or zones. Assign your sensors and GrowAI Hub to each environment you want to track.
Log every plant with its species, growth stage, and ideal conditions. GrowAI tracks its health over time.
Our AI runs automatic checks every hour, catches problems early, and posts updates to your farm chat 24/7.
We've been testing GrowAI with a small group of indoor and hydroponic growers. Here's what they think so far.
"HarvestBot caught a pH drift at 3 AM that I would have missed until morning. Would have lost my whole harvest. Genuinely saved my grow."
"The VPD tracking alone is worth it. I used to eyeball temperature and humidity separately — now GrowAI shows me live VPD by stage and I haven't had a powdery mildew issue since."
"I run a veg tent, two flower tents, and a clone station. GrowAI pulls all four into one dashboard with separate alerts for each. Nothing else on the market does this."
