Installation and Tutorial Of Inline Duct Fan Kit

Cherie Crocker | 06 juillet 2022

Proper ventilation is crucial to the success of your small grow space. Like all plants, cannabis plants require fresh air and proper air circulation to grow at their best. This is why it’s essential to learn the installation and tutorial of an inline duct fan kit in your indoor cannabis grow area.

If you want to improve the health of your plants dramatically, you need to install an exhaust system to push out stale air and excess heat and let new, cooler air into your relatively sealed environment.

Installing the wrong fan and exhaust system will limit the potential of your plants to yield the best harvests possible. It can lead to inefficiencies in the system. 

So it’s essential to make sure that the size of your inline duct fan will match the size of your grow space, whether you’re new to growing indoors or you’re already an expert.


The Importance Of Fans And Exhaust In Your Grow Room

The quality of the yield of your indoor plants will depend on the availability of fresh air in your grow room. This is why an exhaust system is a necessary investment for growers, especially commercial ones, in terms of equipment and energy costs. 

Smaller grow tents may not need hefty requirements compared to commercial tents, but it doesn’t mean you can already ignore fresh air requirements and under-ventilate your crops. 

As compared to outdoor environments, greenhouses and grow tents become extra humid or hot because of evaporated moisture. You need to get rid of this damp, stale air out of your space to improve the growth of your plants and reduce the onset of pests and diseases.

Fans plus ventilation will improve the robustness of your plants. You will need an exhaust system plus carefully positioned circulation fans to help improve airflow in your tent and replicate the conditions of an outside environment. Fresh air makes plants happy and will thrive easily under moderate temperatures.

Also, having an exhaust system and properly sized fans can help avoid and fix the common mistakes that growers commit (such as overwatering) in the grow room. A fan with temperature and humidity controls will balance the effect of overwatering your plants with the help of pre-set programming.

An exhaust system will help regulate the moisture content in your grow area by pulling humid air and pumping in fresh cool air. This can fix your overwatering issue in only a short period and make everything return to normal.


How Inline Duct Fans Work


Given the reasons stated above, installing an inline duct fan in your grow tent is one of the essential elements to consider. This will help you manage the flow of air in your grow space, maintain the proper temperature, and remove the pungent smell contained in the room.

An inline exhaust fan is installed for extricating waste. The proper place to establish this would be in an area that will provide ideal air filtration benefits. You need to look at several components to ensure the efficiency of your inline exhaust fan. 

Such components include the distance of the duct where the air goes through and the power rating of the fan’s engine. You also need to consider the size of your room.

Advantages Of Installing An Inline Duct Fan In Your Grow Tent

Here are the top benefits of using inline fans in your grow area:

Decreased Noise Levels

Given that you install your fan in the proper area, you will find the noise levels in your grow room get insignificant. You will also benefit from having fans if you happen to have a rooftop space that is insulated. 

Demonstrated Capacities Because Of Ducting

Compared to basic fans, inline fans work with ducting and thus tend to have more capacities. This is especially useful if the distance between the power source of the fan and the extraction source is considerable. 

You Have Multiple Intake Points

Inline fans can be used with DIY techniques to make a few inlets or outlets. This is very helpful, especially if you have a large grow room that will need a few intake points. 

Key Components For Installing An Inline Fan System

You will need to deal with the following components when putting an inline fan system in your grow area to get rid of negative airflow:

Intake Vent

You will need an interior vent that serves as the place of extraction for the inline system. These grills and vents come in different shapes, sizes, and colors, so you can freely choose the parts that suit your growing area. The short vent will help lessen the air’s travel distance.


This is the main part of your grow tent system. There are different factors to consider in choosing a fan for your area. Such factors include the specific applications of the fan and the size of your grow room.


Connecting the vent to the engine plus connecting the engine to the external vent later on, may require you to do ductwork. The best ducting for your grow room is the flexible ones, such as insulated ducting and semi-inflexible ducting.

Outer Vent

This could be a vent installed on the rooftop or an external wall vent. You will find different kinds of alternatives for this classification.

Exhaust Fan Calculator

This is needed to measure the extraction level required for the system. You would benefit from installing a fan with the same distance across the length of your ducting. 

It’s sensible to use a fan with a particular ducting width. You can reduce the amount of work the fan needs by decreasing the length, and it’s already enough to filter the air.

Other Accessories

Having a shutter alongside the ductwork will also benefit your grow room as this will help prevent specific issues, such as backflow of air. It will also assist in keeping the system shut when you’re not using the fan. A duct tape should be enough to keep everything set up. You can also use duct claps to complete everything.

Benefit Of A Ventilation System For Your Plants

Your grow room should maintain the best climate possible for your plants. It should compare with the air that is available outdoors. This means that you need to supply your grow room with fresh carbon dioxide.

The ventilation system will help maintain the levels of carbon dioxide in your grow room, which would be ideal for the best development of your plants. You will need a steady flow of natural air from the outside as the grouping of carbon dioxide in the air gets low. 

Since plants are usually grown outdoors, they are exposed to the wind and other elements. Not having these elements can compromise the growth of your plants. Thus the need for proper ventilation in your grow room.

How To Install An Inline Duct Fan In Your Grow Tent

Doing the installation may sound complicated, but it’s easy to do by yourself. You need to understand the process, with the critical factor of ensuring proper airflow so that the ducts will not have any bends.

Place Your Inline Fan On The Ceiling Bars Of Your Tent

Hang the inline fan to the roof bar of your tent by using flexible clasps. Let the fan hang a few inches away from the ceiling. The key is to make sure that there is sufficient space on the ground to help expel the hot air from the upper portion of the tent.

Hang The Carbon Filter

You can place your carbon filter inside or outside the tent or place it safely on the floor. Just make sure that you’re installing the filter correctly.

In attaching the fan, make sure that the tapered end faces the exhaust hole. Then use the remaining straps to secure the carbon filter, with the flange end facing the filter. Use clips to secure either end of the duct fan. 

Now, fit the other section to the carbon filter. You might need another technique to put a filter on the flow.

Using an inline fan and air carbon filter ducting ventilation combo can make this process easier.

Connect The Fan To The Ducting System

Failing to connect the inline fan properly to the ducting system can be faulty. The end goal should be to connect the ducting properly to free up the movement of the exhaust gasses. 

It would be best to keep the piping free from bends to avoid perforations. The ducting should not send in light, and the length will not compromise the fan’s efficiency. 

Your ducting should make your tent light-proof. You can use a U-shaped bed if you want to avoid light from infiltrating your nursery. You should also ensure that the ducting passes through an exhaust opening and that the tent is closed, especially where the ducting goes out from the structure.

Also, why not make installation easy by using an inline fan and air carbon filter ducting ventilation combo?

Attach The Power Cords

Practice safety when you connect the fan to your electric source. We recommend having a certified electrician help you out since they have the knowledge to install electrical connections safely and securely.

Plan The Setup

There are various setups to consider for this, but the most common is to hand the fan and filter within the tent. This is the best method, too, when you have small to medium-sized carbon filters.

Doing it increases your growing footprint and lets the air through the filter. The air will be free to move more slowly and can help control the smell. This setup also helps remove the hot air from the top portion of the tent.

If your carbon filter is too big to hang from the roof, then you can place it inside the tent, on the floor. Remember that this is not the best setup since your filter might draw more heat down and direct it towards your plants. The floor space that it will occupy may become bothersome too. 

You should avoid putting the fan and filter outside the tent as well. Yes, it does save space, but this may also push the air through your filter at high velocity and be helpless in smell control. Having the fans set up outside will also generate noise.

When installing a carbon scrubber and ventilation fan, consider the following steps:

  • Using adjustable clips, connect your inline fan to one of the roof bars in your grow area. This will work nicely in hanging the fans from the roofs.
  • You can either connect the inline fan to your ducting properly or place the inline fan over to fit easily in the exhaust opening. The inline fan should go through and out an exhaust opening.
  • Hang your carbon scrubber – it should come with ropes to make the installation easier.
  • Connect the carbon scrubber to your inline fan so that the fan will let in air through the scrubber. You can use ducting or connect them if they have a similar size.
  • Make sure that all your parts are of the right size before putting them all together. 

Never make fans and exhaust an afterthought for your room. This is especially true for commercial growers. Your grow tents should have the space to insert a complete exhaust system. This will make setup and installation easier.
