GroLab TankBot

Take your cultivation to a professional level

Imagine a system that continuously monitors and adjusts key watering parameters for you. That's exactly what TankBot is - the most versatile and accurate module in the GroLab range, designed to completely automate tank management. Whether you're growing tomatoes in hydroponics, herbs in a grow box or chillies in bulk, TankBot gives you absolute control and peace of mind.

Key features and benefits of TankBot

Your plants always get exactly what they need. TankBot is the brains behind your watering and allows you to achieve consistent results with minimal effort.

• Comprehensive tank management: automatically monitors and controls pH and water temperature. When you connect the optional EC probe, you also get full control over the nutrient concentration in the solution.
• Precise dosing of nutrients and additives.
• Inaddition to pumps, solenoid valves, relays or contactors can be connected to the 4 independently controlled outputs to control irrigation, lighting or ventilation.
• Expandable and safe system: Up to 4 switching sensors such as water level sensors, smoke or motion detectors can be connected to the module to create advanced safety protocols.
• Scalability for large projects: up to four TankBot modules can be connected to a single GroNode central unit to control complex multi-tank systems.

Full automation and safe operation

With TankBot, you can set up advanced automation scenarios. Let the system automatically refill the tank when the level drops, or program a complete nutrient solution change at regular intervals. With safety sensor support, the system will immediately alert you to a water leak, smoke or other anomaly and can automatically activate programmed actions - such as turning off pumps or lights.

Easy connection and control

TankBot communicates wirelessly (2.4 GHz) with the GroNode base unit from up to 25 metres indoors. All setup, real-time monitoring and data analysis are conveniently performed via the freely available GroLab Software. If the GroNode is connected to the Internet, you can control and monitor the entire system from anywhere and receive email alerts. For quick manual intervention, the module is also equipped with physical buttons and its status is indicated by clear LED indicators.
