Ostara is a polytunnel climate control system that brings monitoring, automation, and control together in one platform.

Most polytunnel growers have sensors or basic set-and-forget controllers, but they're disconnected, and optimal conditions still depend on manual intervention (and the time and labour costs that come with it).

Ostara connects your existing hardware, automates responses to changing conditions within parameters you set, and gives you full visibility across your entire operation from one dashboard. Plus, the system learns and improves over time, and our team of polytunnel experts works alongside you to help you act on what it's telling you.

Unlike generic farm management software, Ostara is a climate control system built specifically for commercial polytunnel growers who want to move beyond manual climate management to optimise for higher (and higher quality) yields.

If you're spending significant labour hours on vent adjustments and manual soil moisture checks, or accepting suboptimal conditions because the alternative isn't economically viable, Ostara is built for you. It works with your existing hardware, whatever type of polytunnel, sensors, or controls you already have in place.

Ostara is suitable for any farm size, from 1 hectare single-tunnel operations to 100 hectare plus complex multi-site farms.

Most climate control systems are built for high-tech greenhouses – sealed, controlled environments with very different requirements to commercial polytunnels. They're expensive, complex to install, and assume a level of existing infrastructure most polytunnel operations don't have.

Ostara is built specifically for polytunnels – open, variable environments with fragmented hardware from different vendors. It works with whatever you already have in place, requires no specialist installation, and connects monitoring, control, and automation in one platform rather than leaving you with disconnected tools that don't talk to each other. Unlike set-and-forget controllers, it learns and improves over time – and unlike a typical software sale, our team stays involved to help you act on what it's telling you.

Most growers are up and running within days. We start with a virtual or in-person demo to understand your setup and explore how Ostara works for your specific operation. Installation is straightforward enough to do yourself, but our expert team is always on-hand if you need support. Once set up, you'll have live data in your dashboard almost immediately, ready to define your required optimisations.

Ostara monitors all key climate variables – temperature, humidity, VPD, ventilation, irrigation, and lighting – from one dashboard, accessible remotely via the app.

When conditions drift outside your targets or extreme weather is incoming, you get customisable alerts so nothing catches you off guard. And the system can also be configured to respond automatically to those changing conditions too, adjusting hardware to exactly the position required within the parameters you've set.

It's a level of precision typically associated with controlled environment agriculture in high-tech greenhouses, but built for how polytunnels actually operate.

Whilst the majority of Ostara installations are in polytunnels, it is running in a wide variety of sites right up to glasshouses. If you're wondering what it could do at your farm, please get in touch!

By automating climate responses and giving you full visibility across your operation from one dashboard, growers spend less time on manual checks and reactive interventions, and more time on decisions that actually move the business forward. Based on labour savings alone, most growers see payback within a year.

In Haygrove trials, Ostara reduced manual labour requirements by 60 hours per hectare per month on vent management alone, and delivered 25% more time with crops under optimal VPD conditions – directly reducing yield and quality losses without additional labour requirements.

As Christi Marmandiu put it: "Ostara has enabled us to make better decisions for the plants and maximise our return-on-investment by having roll-up venting connected to our sensors. Now Ostara might cause our vents to operate two or three times every hour to keep conditions optimal – the manual labour needed to achieve that would be a huge, huge cost."

Pricing depends on your operation size and which products you need – start with monitoring only with Ostara Sense and scale later, or go full climate control with Ostara Control. Flexible payment options are available, whether that's an upfront investment, leasing, or a simple monthly fee.

Ostara isn't just a one-off software sale, it's an ongoing partnership. We help you configure the system to your specific operation, support installation and training, and stay involved long after you're up and running. Our team of polytunnel and data experts provides regular reports and insights to help you get more from the system over time. And if anything goes wrong, we're on-hand to keep things running.
