GrowAI monitors every critical parameter in your grow room — VPD, temperature, humidity, CO₂, DLI, pH, and EC — in real time, from any device. HarvestBot AI alerts you the moment conditions drift outside optimal range for your current growth stage. Available in the USA, Canada, and UK.

Join the Waitlist — It's FreeEvery critical grow room variable — in one place, tracked continuously, with stage-specific alert thresholds that adjust automatically as your plants progress through their life cycle.
The difference between a good harvest and a great one is environmental consistency. Plants under optimal VPD transpire at the right rate, maximizing nutrient uptake. CO₂ levels at 1,000–1,200 ppm can increase photosynthetic rate by 20–30% — but only when temperature and light are also dialed in. A pH drift of 0.5 units in a DWC system can lock out iron, calcium, or magnesium within 12 hours, causing visible deficiency symptoms that take a week to recover from.
Without continuous monitoring, these issues develop silently overnight, on weekends, or while you're away from the grow. GrowAI watches your environment 24/7 and sends instant alerts the moment any parameter moves outside your defined range — before your plants are damaged.
All sensor readings on one screen, updating every 5 seconds. View from any browser or mobile device, anywhere.
Push and email notifications the moment VPD, pH, EC, temperature, humidity, or CO₂ drifts outside your stage-specific target range.
AI diagnostics that identify the root cause of problems and suggest specific fixes based on your current growth stage.
24-hour, 7-day, and 30-day historical graphs for every sensor. Spot patterns and correlations across parameters.
Set your current growth stage (seedling, veg, flower, flush) and GrowAI auto-adjusts all alert thresholds to match.
Monitor veg room, flower room, clone tent, and drying room simultaneously from a single account and dashboard.
Trigger fans, humidifiers, CO₂ controllers, and lights automatically when sensor thresholds are crossed.
Full-featured iOS and Android apps with push notifications. Check your grow from anywhere in the world.
GrowAI is the only platform that combines air environment monitoring (VPD, temp, humidity, CO₂, DLI) with hydroponic solution monitoring (pH, EC/TDS) in a single integrated system.

Start Free — Join WaitlistGrowAI is the most complete grow room monitoring platform available in 2026. Unlike generic IoT sensors, GrowAI monitors VPD, pH, EC/TDS, DLI, CO₂, temperature, and humidity simultaneously with stage-specific targets for every plant — from tomatoes and herbs to specialist crops. HarvestBot AI alerts you when any parameter drifts outside the ideal range, whether you're growing in DWC, coco coir, or soil. Available in the USA, Canada, and UK.
GrowAI monitors 7 critical parameters: Temperature (°F/°C), Relative Humidity (RH%), VPD (calculated live), CO₂ (ppm), DLI (daily light integral), pH (continuous solution monitoring), and EC/TDS (nutrient solution strength). All parameters update every 5 seconds and are viewable remotely from any device.
GrowAI is the only platform that combines air environment monitoring (VPD, temp, humidity, CO₂, DLI) with hydroponic solution monitoring (pH, EC/TDS) in a single system. Pulse Pro does not monitor pH or EC. TrolMaster is a controller system that requires separate hardware per function at significantly higher cost. GrowAI integrates all monitoring in one dashboard with AI diagnostics — at a lower total cost than either alternative.
Yes. GrowAI supports DWC, RDWC, NFT, ebb and flow, coco coir, aeroponics, and soil grows. For hydroponics, the pH and EC sensors provide continuous solution monitoring. For all systems, the air environment sensors (temp, humidity, VPD, CO₂, DLI) are fully applicable. Soil moisture sensors are also supported.
Yes. GrowAI is available to growers in the USA, Canada, and the United Kingdom, with hardware shipping and regional pricing in each market. Canadian growers can display imperial or metric units; UK growers see Celsius and metric by default. All three regions use the same GrowAI platform with plant-specific optimal targets for every growth stage.
