Fog system : as the pad and fan system, it uses evaporative cooling method to cool down greenhouse temperature. Clear water is pushed through a stainless steel nozzle. Then, the particles of this water are evaporated before they reach the crops. This system works with a pump unit fitted with a high pressure pump.
Humidity deficit : difference between the maximum water vapour content at the actual temperature and the actual water vapour content. Unit in g.kg or g/m³.
Latent cooling : it is the capacity to remove the moisture from the air.
Latent heat : it is the amount of energy exchanged between an object and its environment during a change of state, i.e. during solidification, fusion or boiling.
Leaf Area Index (LAI) : it characterizes plant canopies (aboveground portion of a crop or plant)
