The Most Important Factors to Consider While Choosing an Inline Duct Fan in 2023

If you’ve ever been inside a greenhouse, you’re likely no stranger to the hot, sticky, and humid feeling that comes along with it. Though your grow tent may not be as large-scale as a greenhouse, it can easily get very hot and humid. Though your plants may love humidity and heat from grow lights, too much of a good thing can quickly become a problem. Fans are one way to help create the optimal environment for growing, yet knowing how to use them effectively can sometimes feel tricky.

At Tree of Life, we love sharing our passion for hydroponic growing with you. We know that getting started with or troubleshooting hydroponics can be overwhelming; that’s why we are here to simplify your growing setup. In this post, we answer some of the most commonly asked questions about both intake and exhaust fans for hydroponic growing. From whether or not you need them, to helping you set them up, we want to boost your success and make growing more fun.

Advantages of Using Inline Fans in Grow Tents

Noise reduction: Since you install the fan in the appropriate area, the noise level in the room you are cleaning will be negligible. Also, if you have a fully insulated roof space, or on the other hand, assuming you’re leaning towards quieter models, you’ll benefit from quieter fans.

Duct Run Length: Inline fans are designed to be used with ducts. This means they hold a lot of the capacity shown compared to the base fans. This is useful if the distance from the point of extraction to the power source is considerable.

For example, say you need to exhaust raw air from your grow tent, the length needs to be as short as possible. Subsequently, this will help improve the fan’s ability to deliver clean air.

Multiple Inlet Points: With an inline fan, it is not difficult to make several air inlets or outlets using DIY techniques. These features are critical when you have a huge growing space and need to have several points of air intake.

The Most Important Factors to Consider While Choosing an Inline Duct Fan

You should have no trouble finding an inline duct fan to add to your HVAC system because many alternatives exist. Besides the fan, you might also need other things to make the system run more efficiently and ensure the fan always has fresh air. So, let’s look at some more things that can search for an inline duct fan to go faster and more quickly.

SIZE:
The 4-inch, 6-inch, and 12-inch sizes are some, that you can buy. An equation can help you figure out how big your grow tent or room should be. First, determine the cubic feet of the grow tent/room where the inline fan will be put. To do this, multiply the length, width, and height of the room/tent by that number.

AIRFLOW:
Airflow is typically measured in (Cubic Feet per Minute), which is how much air the fan moves in a minute. This is actually the amount of air the fan can move in that particular time. If you know how big your tent is, you can choose the right CFM for an inline fan.

SOUND:
In general, no one likes noise, especially regarding appliances used in the home. It’s common to see product descriptions for inline fans that truly describes the amount of noise the product produce. Make sure you check the noise level of the inline fan, before you buy one. If you set the fan speed too high, it will make more noise. Other than that, if you slow down the speed, the less noise it makes.

SPEED:
Automatic controllers are found on most inline air fans. This means that you can set the speed of your fan with them. It would help if you controlled the speed of the fan to keep the humming and the amount of air your plants get from the fan down.

PRICE:
There are a lot of cheap inline duct fans on the market, but there are also some that cost a lot of money. It would be best to choose what fits your budget and works well in your grow room or tent.
