Humidity control is a important component of protected agriculture , and one around which the discourse is systematically develop . Whereas relative humidity was previously the main argument view by raiser , vapor air pressure deficit is becoming an manufacture standard when discussing humidness in greenhouses and indoor farm . Relative humidity express the amount of water vapor in the aviation in relative to the zephyr ’s saturation point , with the air ’s piddle - holding capacity varying accord to the air temperature . Alternatively , VPD expresses the difference between the air ’s water content and its saturation head in terms of insistence , make it independent of temperature and a more accurate parameter for model transpiration by plant . A mellow VPD indicates that the pee vaporization pressure in the air is significantly low than that of the leaves , driving piddle loss and potentially devastating the crop . Mark Stanley , CEO of California - based MicroCool , explained that humidity ascendance system have ameliorate dramatically in the past 40 days , part of which is due to an increase focus on VPD . MicroCool manufacture high-pitched - quality fogging and misting system , which have been installed in greenhouses and indoor growing facilities across the world . While “ the shot of microscopical water droplets has [ not essentially change in 40 years ] , the automobile that is driving it is much more advanced and the machine that is see to it the on / off and sustenance of humidity level is much more advanced . ”

MicroCool ’s gamey - pressure fog system control humidity by grow 1000000000 of microscopic water droplets ( < 10 microns in size ) , which soak up energy from the surround air to commute State Department , creating water evaporation and effectively increase humidity . This New York minute evaporation , made potential by the droplet ’s microscopical size , is also defined as adiabatic cooling system , as the water droplets absorb heat during evaporation . According to Stanley , “ the amount of fog that you may actually inject into the atmosphere is very much dependent on the air that tune that you are injecting it into ” . Using desiccate regions as an model , Stanley explained that fogging systems are especially effective in hot , dry region as the grower can inject a meaning amount of fog into the zephyr for cooling and humidification .

away from adopting a VPD - base approach to cooling and humidification , Stanley also explained that fogging and misting systems have gain from improvements to reverse osmosis systems ( which can be let in in MicroCool ’s organization ) . Reverse osmosis ( RO ) organisation allow growers to remove minerals , bacteria and viruses from the supply water , thus keep equipment corrosion , calcification of schnoz and the likely deposition of calcium carbonate onto the crop , which is non - toxic but can add an unsuitable sheen to the crop . fortunately for growers , the cost of RO systems has decreased significantly since the technology ’s introduction , and the use of valve throughout MicroCool ’s system of rules also allows the agriculturist to reduce pressure in the water lines without draining all of the RO H2O , thus providing water savings to the grower .

MicroCool also addresses piss quality by incorporating UV lighting to shoot down H2O - borne pathogens . As Stanley explains , the water droplet are 10 % of the diameter of a human hair , thus are well aspirated by plants and humans ; water quality is therefore imperative .

According to Stanley , the most important element of a fogging and misting system is the controller . An in force haze system require a eminent - quality controller and while such control may seem prohibitively expensive , Stanley ensures growers that “ a fog organization is only as unspoilt as the controller behind it . ” A well - designed control organization permit for the accurate measurement of glasshouse weather and the subsequent conflict of the haze organization to take on crop essential . While MicroCool does not have a proprietary controller , the company works with legion providers to insure that its fog organization are in effect integrated into greenhouse military operation and match the grower ’s capabilities .

Whereas MicroCool ’s IBEX Heavy - Duty Industrial Humidifier System is most suitable for glasshouse and high - headroom sites , the company has developed the FOCUS scheme for low - headroom induction such as indoor grow operation and low-toned greenhouses . As Stanley explain , the nidus system lie in of “ item-by-item beak , each with a solenoid valve , and they can be set along the paries in strategical positions to furnish humidity for indoor growers . [ The murk ] is even finer than that used in greenhouses . ” With these innovations in hand , MicroCool confidently provide high - quality fogging organization to a encompassing compass of growers across the world .
