Yes. You will always be the owner of your data and you can withdraw it anytime. Our service complies with GDPR; the General Data Protection Regulation of the European Union.

The General Data Protection Regulation (GPDR) is a European Union law that was implemented May 25th 2018 and requires organisations to protect personal data and uphold the privacy rights of all persons within the EU territory. The regulation includes seven data protection principles that must be implemented and eight data privacy laws that must be facilitated. It also authorises the data protection authorities to enforce the GDPR with sanctions and fines.

As user of the Log & Solve dashboard you will always be the owner of your data. You can trust that your data will be treated absolutely confidentially and will not be shared with any third party without your explicit consent. Log & Solve is a service and property of Klasmann-Deilmann.

a) To provide the Log & Solve service b) To support you with customised advice, the Log & Solve team can access your data and prepare a statistical evaluation c) To send automated, timely alerts about the cultivation status of your crops d) To carry out anonymized statistical analysis to improve our services continuously e) To adapt and improve our data security measures.

Yes. Your historical data always remain secure in your dashboard. You will be able to create separate crop sheets for individual crops and batches in your dashboard which will be filed for future access e.g. for comparisons of different batches from different years.

Log & Solve meets high security standards that are generally accepted. Log & Solve is hosted on Amazon AWS, one of the most respected and secure cloud hosting solutions on the market. Our servers are monitored for suspicious activity and the latest security updates are regularly applied.

Yes. You can use the dashboard for free for a test period of two months.

The Log & Solve dashboard is available in various monthly-based subscriptions providing different functionalities. The basic subscription allows using the Log & Solve dashboard with the log functionalities for your different crops and different batches.

In addition to the basic subscription, Log & Solve offers different add-ons, which can be tailored to your needs and cultivation system:
Substrate Sampling Service, Sensor Systems (e.g. substrate moisture, substrate temperature, air temperature, radiation, etc.), and Technical Advice Service

Please contact us for a custom-made proposal.

Yes, you can log data like notes, pictures and analytical results per cultivation batch and per crop. The Log & Solve team can support you to create data pages for new cultivation batches and crops in your dashboard if required. Previous crop data will still be available.

All analyses will automatically be uploaded to your dashboard by the Log & Solve support team. The laboratories we are working with for Log & Solve supply the data in a suitable format for automatic uploading.

Yes, you can use Log & Solve on your mobile devices. The dashboard and all its features are fully accessible with smartphones and tablets. It is possible to add photos to the dashboard from your photo gallery or even take pictures with the camera of your mobile device directly within your dashboard. Notes are also possible to be uploaded with your mobile devices.

Klasmann-Deilmann can support your cultivation strategy by providing digital expertise on substrate and water analyses in combination with other available data such as photos, weather records, sensor data and notes to assess the current crop situation. Log & Solve is an additional service by Klasmann-Deilmann, it does not replace nor affect the service you are currently provided with by Klasmann-Deilmann.

A substrate moisture sensor is a device that measures the actual moisture level in the substrate during cultivation. The sensor can help to determine how much water is actually available to the plants.

A moisture sensor measures the volumetric moisture content. It determines how much % of the pot volume is filled with water. The rest consists of solids and air. There are
different types of substrate moisture sensors available, but most types work on the principle that water conducts electricity. These sensors use electrical resistance measurements to determine the water content in the substrate.

Knowing the moisture content of the substrate can help growers to make data-based, well-founded decisions about when and how much to irrigate their crops. This will avoid strong fluctuations between wet and dry during cultivation, so the plant experiences fewer stress situations. Preventing the root zone from drying out too many increases the efficiency of irrigation. This results in better water uptake and larger uniformity of crops.

We recommend placing one substrate moisture sensor per 200 m² and at least 3 in a cultivation batch. You can also decide for yourself, based on the number of pots you currently judge for irrigation decisions, to determine how many senors should be used. If you currently look at e.g. 10 pots in a batch, we recommend also to use 10 sensors.

It is not necessary to place a sensor in all batches. Choose a representative batch that is comparable for the surrounding crop types. If your crop types are very different in its requirements, then multiple sensors in multiple batches may be the better decision.

Place the substrate moisture sensors in the area you normally would control for irrigation decisions. Or place sensors in each quadrant of the cultivation batch. Also consider placing additional sensors in areas that have experienced higher humidity deviations in the past.

Upon delivery of the sensors, you will receive instructions on how to place them correctly in the root zone. Place the sensors at a consistent depth, preferably at the depth of the root zone. Insert the sensor vertically straight into the substrate. Make sure that the entire electrode is in contact with the substrate and avoid a slanted sensor position.

The sensors are very accurate with only a small deviation. Deviations which may occur are often caused by external conditions. These include:

• Too much air / space between substrate and sensor electrode
• Pot temperature is very high
• Sensor is too long for the used pot
• Sensor electrode is in contact with e.g., a small piece of wood, a clay particle or a small stone instead of the soft, water-bearing substrate area

The sensors connect to the Sigfox network, which has globally a very good coverage. This international 0G network is a remote data transmission system with low power consumption.

The connection to the sensor is wireless and therefore not wired. With a wired sensor, we expect a continuous line to appear in a graph. With a wireless sensor, small dropouts can occur again and again, as they can in the GSM network. In a telephone conversation, the spoken word is then interrupted in parts. This can also happen in your sensor diagram. If your sensors show frequent dropouts, we can amplify the signal e.g., with another antenna or a gateway.

Immediately after potting, the substrate in the pot is often not yet sufficiently settled and compacted. The best time to place the sensor is after the pot has been irrigated at least once after potting. This ensures better contact between sensor electrode and substrate. For soil-grown outdoor crops, this applies to situations where the soil has been freshly worked, so reliable measurements starts after rain or first irrigation. In substrate slabs and growbags in vegetable cultivation, this applies to situations prior to the first full drip. For reliable start of sensor measurement, the slabs should be thoroughly water saturated.
