If you are gardening indoors, you know that your wire duct plants need water, food and light to flourish. Because sunlight is not available indoors, indoor gardeners have to provide a light source for their plants and they do this with grow lights. If you are using HID lights, or high intensity discharge lights, one of the side effects that you will notice is that the light bulbs will heat up with use. If you have several grow lights in your indoor garden, as would commonly be found in a greenhouse setting, all of those lights are creating a tremendous amount of heat. While some heat is good for plants tixiyall, an excess of heat can kill them very rapidly, and so greenhouse growers and other indoor gardeners will need some type of grow room ventilation system, so the excess heat is exhausted outside. http://en.wiring-duct.com.cn/map.html
A key component in any grow room ventilation setup are the grow room fans. Fantech Fans is a top manufacturer of grow room fans, and they offer several popular models, including wiring duct duct fans and inline fans. Fantech fans are made from galvanized steel and come with ball bearings that are permanently sealed. You can fully control the speed, and they make the connection easy for you because the wiring on their grow room fans is external. The grow room fans come in six-inch, eight-inch, ten- and twelve-inch sizes, and a speed control unit is also available.
