This new greenhouse technology is helping greenhouse growers win a long-standing battle against low humidity and high temperatures – conditions that can trigger plant water stress. Through leaves, plants lose most of their moisture from evaporation, and they get most of the carbon needed for growth from carbon dioxide. Controlling plants’ pores by effectively controlling the climate can result in stronger, healthier plants.
Fog systems are a proven way of providing needed humidification along with cooling via evaporation. Among high-pressure fog systems, static line systems and vertical fan systems have been common choices.
Developed using customer input, the Fogco Revolution aims to achieve complete humidification of greenhouse areas up to 10,000 cubic feet without fallout or wetness.
The technology achieves continuous, even, 360˚ humidification coverage by broadcasting an “invisible mist” outward in a horizontal circle along a stream of air. By integrating the air stream with the fog, its micron-sized water droplets are suspended much farther and longer than traditional systems. This provides even humidification, more complete evaporation, and virtually no fallout. Through flash evaporation, temperatures can be reduced up to 30˚F and humidification levels maintained near 90 per cent.
Because the Fogco unit can adapt to humidity or temperature changes up to three times faster than static line systems, plants continue growing longer and healthier within tighter humidification and temperature ranges.
Fogco Revolution can save up to 35 per cent on water/electricity costs – up to 75 per cent compared to vertical fan systems. Simplified installation also reduces costs.
Fogco Revolution can be mounted from any overhead structure, indoors or out, and comes with an outdoor rated fan and powder-coated enclosure. It is portable when mounted from a custom stand. It is designed to operate with any Fogco pulley-driven or direct-drive 1,000-psi fog pump and is customizable with the appropriate Fogco nozzles.
