Fans en ligne

There are many different capabilities, sizes, and configurations of inline fans- they may have single or multiport options. With single ports, there is one outgoing exhaust duct and one incoming supply duct. Whereas with multiport versions a single fan is able to manage the movement of air in various locations. These fans will fit perfectly in your grow tent. 

Inline fans help to conduct air in your grow room and are adhered in line with the ductwork, they will position air from the inside and out of the grow room. Typically you will find three different fan controllers in a grow room. Solid state fan speed controllers, Variable autotransformer (Variac) fan controllers, and variable frequency drives (VFD, AFD).

Most often when you are searching for information about grow operations and inline fans you will discover information on how to mask the sound and vibration. If there is too much vibration, suspend the fan with bungee cords that are elastic to absorb the vibration and stop the rattling.

Another smart idea is to insulate the box in order to eliminate the hum of the motor. This can be done cheaply with a sleeping bag or blanket and some duct tape. Or it may be the noise from the air rushing throughout the venting which contributes to the grow room noise. Having bends in the vent run and a powerful fan will worsen this problem. Due to this, make sure your vent run is as short as it can possibly be- straight is the way to go- rather than with rambling, long, curvy runs.

Be cautious of insulation fibres getting into the grow area and ruining the crop, therefore insulate the venting of your inline fan. Vent sleeves and insulated vents have fibreglass insulation pre-wrapped in them and are typically 8 feet lengths and can be pricey. They are however the easy option for a short vent run. Keep in mind that it is recommended to avoid fibreglass insulation in a grow space, so it is common to shop for other options.
