Adiabatic cooling (also called evaporative cooling) works on the principle of water evaporation. It means that the air is cooled to a desire temperature for the crops. Positive pressure adiabatic cooling is getting more popular in North-America...

The Vapor Pressure Deficit (VPD) is one of the main forces driving evapotranspiration in plants. The VPD is the difference between the maximum amount of water the air can hold and the amount it does contain. ore and more growers are doing VPD...
The use of high tunnels (covered with plastic film) is widespread especially in Europe and North-America for many target crops. [...] Growers usually use the passive ventilation on the sides with manual or motorized mechanisms called sides roll...
DLI is now a common term (measurement) used by commercial growers and plant scientists. In this article,an interactive and useful tool made by Joanne Logan and James Faust to check the Annual and Monthly DLI Values (mol/m2/day) in the United...
The "psychrometric diagram" of humid air is a tool to facilitate the representation of air transformations. [...] The basic concept is that there is a relationship between temperature and saturation humidity
Some UV radiation can interfere with growth, development, photosynthesis, flowering, pollination and transpiration...
The concept of positive pressure ventilation consists of mechanically injecting fresh air from outside to inside the greenhouse into the growing area. Positive pressure ventilation allows for maximum exclusion of insects and uniformity of...
Vanilla is one of the most expensive spice in the world. It is highly used for the perfumery and the food industry, in fact, for both usages the vanillin content is the main target at the end of the extraction process. Indeed, the concentration...
Fogging system is an essential equipment in the greenhouse industry. The major advantage of the high pressure fogging is to flash evaporating billions of tiny water particles [...] It is more efficient than a low-pressure fogging to decrease...
Today, companies are working on photoluminescent films to cover the greenhouse roof and claddings. The new film has a pink color with new technical proprieties... These films are specially designed to modify and optimize the light spectrum
