climate battery greenhouse system to produce food without energy cost

Climate-battery energy savings low tech...

The first objective of a climate battery greenhouse system is to heat the growing area without using expensive fossil fuels (or electricity). Indeed, more than ever the dependence on fossil fuels and their increasing cost pose problems for...

Adiabatic positive pressure cooling system

Is positive pressure cooling a good...

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...

greenhouse growers should pay attention to vapor-pressure deficit and not relative humidity

Why the Vapor-Pressure Deficit (VPD) is an...

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...

Optimal daily light integral for leafy greens crops with hydroponic system NFT

Daily Light Integral interactive tool for...

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...

Greenhouse engineering: psychrometric chart

Air humidity – How to read a...

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

Positive pressure ventilation strategy

Active ventilation: a positive pressure...

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...
