Platform upgrade: Growing Degree Units

April 09, 2020

Since we started working for you, the growers of the world, we have been guided by our very first grower customers in how we have developed every element of our business. Now our portfolio of sensors reflects the metrics that you want to monitor, our software is reflecting the ways that you want to analyse that data and communicate with others about those insights.

One of the calculations that we heard about many times was growing degree hours (days more commonly in arable environments) or chill hours, especially for our fruit growing customers. While researching this in more detail, collecting information about the various models and conventions, we realised just how common and useful this calculation was across pretty much every crop. Not only does it allow you to monitor the development cycle of your crops, but also the lifecycle of various pests. That’s why we decided to launch a new Growing Degree Hours/Days (GDH/GDD) widget within our platform.

Our platform needs to be flexible enough to allow growing experts to best make use of the tools that we provide. To this end, our GDH widget will be released with fully customisable parameters from start date, sensor selection, temperature threshold level and a “target level”. And it will continue to evolve to enable the grower to instantly get insight from any of their crop level sensors into how well developed the crop is going to be at a particular point in time. 

This very same principle can be applied to any of your Integrated Pest Management (IPM) consultants’ knowledge. Let them know you have started to see the larvae of a particular pest and they will be able to let you know how much heat accumulation there has been from your sensor in that area, which will have been sufficient to let that pest develop. This will enable you to make a decision about how desperately you need the relevant biological control to fight the next stage of the pest!

Cultivation variables explained: growing degree units

In this blog, we would like to tell you something about growing degree units (GDH / GDD). The reason we added this to our dashboard is that during a lot of conversations our users often ask for this. Degree hour insights are used to pro-actively control cultivation. Growers however indicate that the calculation is time-consuming ...

Autonomous growing is no longer a far-fetched dream

The Autonomous Greenhouse Challenge has come to an end and we made it to the finish line. Our multidisciplinary team of horticultural experts and computer scientists from Delphy and 30MHz grew healthy cherry tomatoes remotely in 6 month’s time. In this period, we were able to develop the system and models needed to control a ...
