Aranet in Action: Building Precision into Your Growing Programme
Timing is everything in IPM. Every biocontrol agent has its own thermal threshold for feeding and reproducing - introduce it outside that window, and establishment and control both suffer.
Glasshouse conditions aren't uniform. The temperature and humidity at canopy height - where predatory mites live and hunt - can look very different from the readings on your main climate computer.
Aranet wireless sensors close that gap. Placed throughout your crop, they map real conditions where your biological controls actually operate, giving you the data to back your programme decisions rather than relying on estimates.
Dashboards built with growers
We've worked with customers to build custom dashboards that go beyond temperature and humidity. Growers are tracking EC (electrical conductivity) rates alongside canopy conditions, building a fuller picture of what's happening in the growing environment day to day.
With this data in one place, growers are refining exactly when they introduce biological controls, feed, and water - matching each to the conditions that give it the best chance of working, rather than
following a fixed schedule.
The result: Growers who understand their own greenhouse conditions in far more depth than before, and who can act on that knowledge with real confidence rather than guesswork.
Steering the bigger decisions
Beyond day-to-day monitoring, this data helps growers call the season timings - knowing exactly when conditions are consistently right to start a bioprogramme in spring, and when to wind it down in autumn.
Thripex / Swirski-Mite Gauges
Note the temperature difference for thrips control with predatory mites. Swirski-Mite (Amblyseius swirskii) is much better suited
to high temperatures than Thripex (A. cucumeris) - a single canopy reading
shows which is establishing well right now.
Nematode / moisture content Gauges
Hot temperatures shown here are more suitable for H. bacteriophora (middle) than S. feltiae (left). Monitor the moisture content of the soil (right) before and after applying.
COMMON QUESTIONS
What is Aranet and how does it work?
Aranet is a wireless environmental monitoring system designed for commercial growing environments. Sensors placed around your growing space measure key parameters - including air temperature, relative humidity, CO₂, soil moisture, EC, and light levels - and transmit data wirelessly in real time. Growers can monitor conditions remotely, set alerts for when parameters move out of range, and use the data to make more informed decisions about irrigation, ventilation, nutrition, and crop protection.
Why is Fargro the right place to buy Aranet?
Fargro is the exclusive UK partner of Aranet. That means we're not just a reseller - we provide full technical support, installation guidance, and ongoing advice on how to use monitoring data effectively within your growing programme. Our technical team, including Laura Davey and Sean Whitworth, can advise on the right package for your crop and growing system.
Which Aranet sensors do I need for my crop?
The right combination of sensors depends on your crop type, growing environment, and what you want to monitor. Fargro offers crop-specific packages for ornamentals, propagation, and salads and soft fruit - or our technical team can help you build a bespoke monitoring setup for your specific operation. Contact us to discuss the right starting point.
What is VPD and why does it matter?
Vapour Pressure Deficit (VPD) is the difference between the amount of moisture in the air and how much moisture the air can hold at a given temperature. Managing VPD is critical in protected growing environments - too high and plants close their stomata, reducing growth; too low and conditions favour fungal disease. Aranet's IR and T/RH sensors allow growers to monitor and manage VPD accurately.
Can Aranet monitoring integrate with my existing growing programme?
Yes. Aranet monitoring works alongside your existing inputs and practices - it provides the data layer that makes everything else more precise. Our technical team can advise on how to interpret monitoring data within the context of your wider Holistic Growing programme.
What happens if conditions go out of range overnight?
Aranet sends instant alerts when parameters move outside the thresholds you set - so you can act quickly even when you're not on site. This is particularly valuable for managing disease risk in protected crops, where temperature and humidity fluctuations overnight can create significant problems.
