Frequently Asked Questions (FAQ) about data-driven growing

What sensors you need depends on several factors. It starts with the crop type. For each crop, we recommend specific sensors.

Your objectives also play a major role. If you want to manage light, you will need different sensors than when monitoring soil moisture or substrate EC.

In greenhouse horticulture, many sensors are available from different suppliers. Ledgnd is fully brand-independent and always advises based on your crop, greenhouse, and cultivation strategy. We assemble a sensor set that fits your situation. Targeted, practical and reliable.

That depends on your goal. Do you mainly want to gain insight or do you want to actively steer? And do you need measurements per department or across the entire greenhouse?

The type of measurement also matters. For a net radiation sensor, one measurement per hectare is usually sufficient. But for single-point measurements, such as leaf temperature or photosynthesis efficiency, multiple sensors may be required to obtain a representative view of the crop.

In short: the number of sensors depends on what you want to measure and what you plan to do with the data. We are happy to advise you on the setup that fits your situation best.

That also depends on what you want to measure and how you plan to use the data. For some applications, such as a stomata camera, a single measurement point is sufficient. When your focus is simply on identifying trends, one sensor often goes a long way. But if you aim to steer on crop responses, multiple data points are essential to ensure accuracy.

Ledgnd helps you determine how many sensors are needed for your goals, with the right balance between insight, reliability and investment.

Correct placement of sensors is crucial for reliable measurements. Exact installation guidelines differ per sensor and supplier. The ideal positioning varies strongly per crop: a Phalaenopsis greenhouse requires a different approach than a rose or vegetable greenhouse.

Even minor deviations can affect data reliability. A sensor that is displaced by just half a centimeter can already produce distorted data.

That’s why, when you purchase sensors via Ledgnd, we always handle the installation ourselves. This way, you are guaranteed proper placement and reliable data you can actually steer on.

Yes, all sensors we supply are watertight and meet the IP67 standard. This means they can withstand rain, humidity and even temporary submersion (unless stated otherwise). You can safely use them in greenhouses with overhead irrigation, without risk of malfunction or data loss.

Yes, we always handle the installation ourselves. This ensures proper setup and reliable measurements. During placement and onboarding, our plant physiologist walks you through MyLedgnd and your greenhouse setup. From day one, you can immediately put the data to use.

Yes, that is possible. Existing sensors in your greenhouse can often be integrated into MyLedgnd. We are brand-independent and experienced in connecting sensors from different suppliers.

Lead time depends on the sensors you select. Some suppliers have longer delivery times than others. In most cases, you can expect to start working with MyLedgnd within 5 to 6 weeks after signing the quotation.

Throughout the process, we keep you informed and coordinate installation and onboarding in time.

During data sessions, our plant physiologist analyzes your greenhouse data together with you. We review growth curves, stress events and the effects of previous interventions. Based on this, we provide targeted advice aligned with your crop objectives.

The purpose of a data session is to identify opportunities for better growth, improved energy efficiency or stress prevention. You bring the cultivation experience, we provide data interpretation – together, we translate this into concrete improvements for your crop.

In MyLedgnd you can independently perform analyses with your greenhouse data. You have full access to graphs, with options to edit lines, compare time periods and analyze specific parameters.

Do you need support or a second opinion? You can always consult our plant physiologists. This way, you can combine your own insights with our expertise whenever required.

Yes, MyLedgnd can be connected to most of the common climate computers. The exact possibilities depend on the brand and version you use.

Our account managers assess the technical options with you and ensure the integration is correctly set up. This way, you maximize the value of your existing data, with everything visible in one place.

Plant stress can result from factors such as light, temperature, nutrients or CO₂. Whether and when a plant experiences stress depends on crop type, variety, growth stage, cultivation system and production goals.

To identify stress properly, you need to combine the view of climate data and plant feedback. Typical indicators include closed stomata, unusual leaf temperatures or reduced photosynthesis efficiency.

With the right sensors and a solid data platform like MyLedgnd, you can detect these signals in time and take corrective action before production is affected.

The cause of plant stress can be identified by analyzing your data in MyLedgnd. In many cases, the source lies in one or more (micro)climate factors, such as excessive light, insufficient water or lack of CO_2.

By combining climate data with plant feedback, for example from sensors measuring photosynthesis efficiency or leaf temperature, you quickly see what’s driving the stress. This enables you to intervene effectively and prevent yield losses or quality issues.

Steering starts with insight. Based on the data in MyLedgnd, you can adjust lighting, screening, irrigation or climate settings according to your crop objectives.

During data sessions, our plant physiologist helps identify trends and abnormalities and translate them into concrete actions. This turns raw data into a powerful steering tool, improving yield, quality and efficiency.
