Growing vegetables

Growing vegetables


Water and nutrition in proper dosages, a perfectly balanced climate and grow lights in the correct time spans. There are many factors that must be fully controlled to achieve maximum yield from your vegetable production. With automatic controller technology from DGT by Senmatic it doesn’t get easier: irrigation, fertilizer, climate, and grow lights in a collective and user-friendly DGT by Senmatic-solution.

Our 360° greenhouse control is linked to parameters that you select to set up your basic settings. That frees time and resources for processes which must be done manually. Working with vegetables means that you typically have long production times – so why not automate where it’s possible and ease work procedures?

DGT by Senmatic delivers the market’s best flexible irrigation and fertilizer system, effective LED grow lights, and stable electronic climate controls that are easy to use.

Automation to ensure minimal use of resources

Manual operation of irrigation and fertilizer is a time-consuming to-do, if you want to ensure that all plants receive water and fertilizer in the correct dosages at the right time. Without full control of irrigation and fertilization you risk poorer yields and unstable plant quality. Not least, you are likely to use unnecessary resources and, consequently, costs, too.

Have you considered how sensors can help you?

If you already have an Irrigation and Fertilizer Mixer from DGT by Senmatic, a number of sensor solutions can be connected to your system. These include solar radiation sensors and drain sensors – and EC sensors for the latter of the two. By using data from the sensors, you can automate your irrigation system, making it conduct pre-selected tasks, as sensors register specific values. If a sensor registers a given variable, it sends a signal to the mixer asking it to set a chosen action into motion.

You could, for example, ask your system to control irrigation based on live data on the solar radiation of the day: Let’s say your system starts at dawn and solar radiation data signals begin. When the sun shines enough to reach your maximum set point, it sends a signal to the mixer to start irrigation, while also re-starting the data summation. At the same time, your climate control can control your grow lights, either completely turning them off or turn down the light intensity to minimize use of electricity, while higher powers provide plenty of sunlight. If weather shifts to sudden rain and cloudy skies, the climate control will continuously register the live data from the sensors and the registrations in the greenhouse and will again turn on the grow lights.

Simply put: You make sure that your cultures thrive without using unnecessary resources. That’s a plus for both your economic and environmental reports.

Concerned about going all in on LEDs? Perhaps a hybrid solution is the best for you

In vegetable productions not only grow lights, but also heat is a critical factor. We know that if you produce tomatoes, for example, it is particularly important that the top heating is correct. That’s why we also know that you probably have some concerns when it comes to LED grow lights, as they do not emit as much heat as HPS fixtures.

In that case we recommend a hybrid solution. In a hybrid solution, HPS and LEDs are combined and placed in a staggered formation in the production area. Doing so, you get the benefits from LED, such as controllable spectral distribution (the percentage of blue light) and light intensity, while maintaining some HPS fixtures to emit heat. It is of course also possible to install a full LED grow light solution.

See how the largest producer of tomatoes in Denmark, Alfred Petersen & Søn ApS, grows tomatoes using a hybrid light solution.

Cucumber production with LED grow lights: From two a week to two a day per square meter

The cucumber plants at the Danish nursery Klarskov Gartneri are well off under the new grow lights from DGT by Senmatic. From harvesting two cucumbers a week per square meter during winter, the nursery now harvests two cucumbers a day per square meter after having installed LED grow lights.

Cucumber production in Denmark does not normally include grow lights. But after several stays at nurseries abroad, where Mads Klarskov, grower and owner at Klarskov Gartneri, experienced and tested production with LEDs and adjustments in spectral distribution, the family-owned nursery Klarskov Gartneri decided to investigate if LED grow lights could be beneficial in its cucumber production in Denmark.

Ultimately, they decided to install FL300 Grow and FL300 Grow White from DGT by Senmatic

Fewer mixers - better results

Fewer mixers - better results

When DanRoses took ownership of an older nursery on the Danish island Funen four years ago, seven fertilizer mixers from the 1980’s controlled all watering in the production, but the process was always monitored by the grower due to instability and errors. Now, fewer new mixers give better results – and peace of mind.
