The Heatmap of LetsGrow.com provides new insight
LetsGrow.com has developed the heatmap to provide more insight into the differences in temperature and RH in a greenhouse. Climate fluctuations in the greenhouses are unwanted. It can lead to problems with the growth of the plants in "the corners of the greenhouses", which in turn can lead to differences in production and quality. Climate fluctuations can lead to molds or other diseases that can affect your plant. How can you prevent this?
Horizontal differences in temperature and RH
By this moment, a greenhouse has a limited amount of sensor units that are connected to the climate computer.
These sensor units measure the temperature, RH and the CO2. These units present the data as if the climate in a greenhouse is evenly spaced. However, recent research has shown that there are greater differences between temperature and RH in a greenhouse than has been thought earlier, according to Ton van Dijk, salesmanager LetsGrow.com
Insights in temperature
Since a few months, it is possible to show the data from all your sensor units in a heatmap.
With the data out of the sensor units we can make an overview of the temperature and relative air humidity in the greenhouse, even on a 5 minute basis. By showing these measurments as a movie, you can get a perfect insight into the temperature in your greenhouse.
we can make a 3D overview of the greenhouse, by hanging the sensor units at different heights in the greenhouse, for example between the plants, at the head of the plant and at the screens.
Ton van Dijk: "With the help of this measurments, we can seriously think about technical adjustments that are needed for the greenhouse, in order to optimise the climate in the greenhouse"
Letsgrow.com can collect, present and analyse the data of every sensor unit. In this way, the heatmap can be expanded by measurements of other systems. With this data, we can make correlations between the different measurements. By making these correlations, we can explain the different situations in your greenhouse and help you to prevent the plants from growth or quality differences, diseases or pests. Our goal is to give you a higher production with a better quality.

Van den Berg Est BV is the best grower of Hortensia in The Netherlands. Marjanne and Tom van den Berg won the Hortensia Award with their Hydrangea macrophylla Caipirinha®. Grower Tom van den Berg: “It all starts with balance.”
Marjanne and Tom van den Berg from Est started growing Hortensia’s for indoor and outdoor uses in 2004. Besides, their company Van den Berg Est BV is a high quality producer of Poinsettia and 1-year-plants. Every friday and saturday the products are being sold at the nursery.
Average vase life of over 35 days!
In week 12 Marjanne en Tom van den Berg admitted the Hydrangea macrophylla Caipirinha® for a test by Knowlede Centre for Product Quality Royal FloraHolland. Caipirinha is a new Hortensia with a distinctive colour. The Hortensia starts green, turns white and then again turns green.
The test was constisted of three phases: Transport (96 hour, 15ºC, packed, in a tray), Shop (72 hour, 20ºC, in a tray) and Consumer (840 hours/35 days). The result: a average vase life of over 35 days!
Three different variables
“At our nursery the plants are the starting point of all our decisions”, says Tom van den Berg. ” Throughout the year we use three different variables: energy, water and ‘assimalates’ of the plant. Therefor our stock is healthier and have more resisant and our customers can enjoy our plants much longer.”
Monitoring these balances is highly automated at Van den Berg Est BV. The company uses the Climate Monitor by LetsGrow.com. Yuri Alsemgeest of LetsGrow.com congratulated Van den Berg Est BV with a delicious cake.
