Turn live sensor data into smarter irrigation and building control. Growbud brings sensors, controllers, gateways, and actionable data into one app for indoor cultivation, greenhouses, outdoor farms, and commercial facilities. FROM ROOT ZONE TO ROOM Connect compatible Growbud devices and see live conditions across your operation. Track volumetric water content (VWC), pore-water EC, temperature, humidity, CO₂, and supported leak-detection inputs. Review trends, compare zones, and configure alerts so you can respond before small changes become costly problems. CONTROL IRRIGATION WITH GROWBUD CONTROLLER The Growbud Controller turns monitoring into action. Bring sensor readings, irrigation zones, valves, pumps, schedules, and automation into a single workflow. Start with a few high-value zones, then scale across benches, rooms, greenhouses, and fields. BETTER CROP DECISIONS Replace timers and guesswork with data from where the crop is actually growing. Monitor dry-backs, identify wet and dry areas, track EC buildup, compare blocks, and refine irrigation or crop-steering strategies with clear historical data and AI-assisted insights. BUILDING MANAGEMENT Growbud also supports environmental monitoring and control for commercial buildings and growing facilities. Monitor indoor air quality, temperature, humidity, CO₂, and leaks in mechanical or boiler rooms. Connect compatible systems through Modbus and BACnet and keep site conditions visible in one platform. CONNECT THE WAY YOUR SITE REQUIRES Pair supported devices over Bluetooth. Extend coverage through Growbud gateways and LoRaWAN for large or remote sites. Growbud’s edge-first approach keeps critical decisions close to the operation and reduces dependence on a constant internet connection. START SMALL. SCALE WHEN READY. Use one Dro or Vero sensor with the free Growbud app, then add Controllers, gateways, more sensors, and additional sites as your needs grow. Monitor sensors, configure alerts, and analyze trends from mobile or web with no app subscription. FEATURES • Live sensor readings and historical trends • VWC, pore-water EC, temperature, humidity, and CO₂ monitoring • Irrigation zones, schedules, valves, and pump control with Controllers • Configurable alerts and notifications • Bluetooth device setup and LoRaWAN site coverage • AI-assisted crop and dry-down insights • Building monitoring, leak detection, and compatible Modbus/BACnet integration • Multi-zone and multi-site visibility Growbud hardware is required for sensor readings and control features. Available capabilities depend on connected devices and system configuration.
