How many greenhouse cooling systems have you seen that can actually substantially drop the temperature in a greenhouse?
Greenhouse misting and fogging companies have tried to meet this need for years but almost all of them have come up short. In fact, I have heard that even the most progressive of greenhouse producers have long abandoned the fogging/misting approach to cooling greenhouses.
Why do misting based greenhouse cooling systems get such a bad rap?
There are probably as many as 100 different greenhouse misting and fogging suppliers that use the same high pressure (1000 PSI) based misting technology. Some of these companies make lofty claims of cooling your greenhouse by 35 degrees or more. However, it has been our experience that when you ask users of this technology how much it actually cools their greenhouses (by average temperature drop throughout their greenhouse), the typical answer we get is about 5 degrees Fahrenheit. What's more, since these greenhouse cooling systems produce mist at such high pressures, they can't maintain a consistent sized water droplet.
Large water droplets, produced in the kind of volume that is required to get a cooling effect can be very detrimental to your plants or crop. This is because water droplets in the 10-20 micron size range (which is the typical droplet size from high pressure fogging systems), when produced in any kind of volume by a mister or fogger will cause lots of residual wetness on your plant and crop surfaces.
So not only do you get only marginal drops in temperature from these systems, you also run the risk of opening yourself up to mold and disease problems.
So what is a greenhouse producer to do?
Well, it just so happens that in recent years a greenhouse cooling system has emerged that utilizes an entirely different kind of fog emitting nozzle. This nozzle produces a consistently sized 4.2 micron droplet that fully evaporates even when producing the kind of fog volume that is necessary to reduce temperatures. Unlike high pressure greenhouse systems, this system emits fog through a large .01" orifice at only 110 PSI. Because of the highly evaporative fog that this low pressure system produces, surface wetness is completely avoided and temperature reduction of 20 degrees Fahrenheit or more can be expected.
This is not a hoax. This system is literally changing how greenhouse producers control their growing environments. If you want to learn more about this technology visit www.fruittek.com .

Some of these producers are paying for these systems in less than a year from the benefits they are realizing.
