How to Setup & Install a Inline Fan in a Grow Tent Airflow
(Carbon Filter, Inline Fan and Duct)
This section is broken down into 3 parts and you must first measure the temperature of the inside of your tent with the lights on.
Try to measure near where your plants would be and based on that, go to the following timestamp:
A. Above 78 Degrees – 0:23
Close the tent and Wait at least an hour to determine what the internal temperature of your tent is and this will determine how you will be setting up your inline fan and carbon filter.
We assume you have only one fan and carbon filter in your setup. There are three different types of setup that apply to every single situation and we will teach you all three versions. Time Stamps are in the description. Please skip to the version that fits your needs.
The first setup is the most common and is for internal temperatures higher than 78 degrees. This setup has you hanging your vent system on the top of the inside of your tent using a hanging pole.
Understand that a complete setup consists of a carbon filter connected to an inline fan connected to a duct that is going through a vent on top of your tent. Based on where your vent is, you want to choose where to hang your fan and carbon filter.
Depending on how you place it, it is entirely possible to have no duct at all and connect your inline fan straight into a tent vent. Hot air rises and what happens in this setup is hot air is being fanned out through the top of your tent. Cool air will be sucked in from the open vent on the bottom of your tent.
You want to put the dust filter on the outside of your carbon filter so it catches all the dust trying to go in. The first thing you want to do is place a hanging pole parallel to the outside pole that you’re hanging your system on. Slide the hanging pole as close as to other. Next we will be hanging the straps for your carbon filter. Hold the buckle just like this so you can see all three slots facing you and the strap is going behind. Pull the strap all the way down and loop it back up ensuring that there is no twists. Now push the end of the strap behind the back of the outside pole you will be hanging from and when you have enough pushed in, pull it from above and over the top hanging pole as well.
Then take the end of the strap and put it through the center slot of the buckle and pull it about 3 inches, then pull up and into the top slot and pull it from behind. Once it’s in, pull on the bottom of the strap to make sure its secure, you could tighten the strap by holding the buckle secure and pulling hard on the loose end of the strap. Tighten it enough so that your carbon filter will fit in loosely, but not too loose. Now do the same thing with the second strap and carefully place the carbon filter inside the two belts.
Next, you want to hang your inline fan right next to your carbon filter and we will be using rope clip hangers. The first thing you want to do is pull out enough slack on the hangers so you have about 3 feet of line. Take a clip without the pulley attached and push it behind the back of the pole you’re hanging from, up above and over the second hanging pole and let the clip drape down.
Do the same exact thing for the second hanger and even the levels. Now depending on your inline fan, you may have a mounting piece that needs to be attached. It is in this gap that you are going to slide the two clips through. Make sure you’re hanging your fan up in the direction where the arrow is pointing away from the carbon filter and pointing towards the vent. This means that air is blowing out of your tent.
Hold the inline fan with one hand make sure the clip goes through that slot, and clip the clip that’s attached to the pulley. Do this with the second clip and now you can let your inline fan hang. Raise the inline fan by pulling the loose rope ends until your fan is level with your carbon filter. Once its connected, you could lift the whole system up even more to be as high as possible.
You could further seal the connection with aluminum tape if you have it. Next, drop one end of the duct through the top vent. Attach this end to the open end of the fan and again you can reinforce this with some tape. Now organize all your cords and plug your fan in. If you have a probe, place it near where your plants would be and now, open up a vent that’s as close as possible to the floor and that’s where the cooler air will get sucked in. The last step is to tighten up all of the other vents and that’s all for this setup.
B. Below 78 Degrees – Limited Space in Tent – 6:30
The two other ways of setting up airflow is for tents that are cooler than 78 degrees. The only difference is whether you are placing this setup inside your tent our outside your tent. Both setups have the carbon filter on the floor with the inline fan on top. like a totem pole and its either blowing or sucking air out of your tent. If you have a small grow tent with limited space, you want to place your fan outside of your tent. First, place your dust filter on the inside of your carbon filter. You just roll it up like a pole, stick in in the center and put your hand on the inside to spread it out.
Next stack your inline fan on top and have it so that the arrow on the fan is pointing down. Since the weight of the fan on top of the carbon filter is heavy, you do not really need to seal this part. Next, place your duct on top and you can reinforce this with some aluminum tape if you have it. Place this setup somewhere safe outside of your tent on the floor and close enough so the other end of the duct. Secure the duct to the vent by tightening the two vent drawstrings. Organize all your cords and plug your fan in. If you have a probe, place it near where your plants would be. Now open up a vent on top of your tent and tighten all other vents and now you have hot air getting sucked in from the top and cool air getting blown out from the bottom.
C. Below 78 Degrees – Adequate Space in Tent – 8:22
The last setup is for temperatures cooler than 78 degrees but with enough space to place your fan setup on the floor inside your tent. With this setup, you are placing your dust filter on the outside of your carbon filter. Then you are stacking your inline fan on top with the arrow point up. The weight of the fan will make sure the connection snug so you do not need to reinforce this part. Next, connect a duct to the other end of the fan and you could reinforce this connection with some tape.
Place your setup on the most convenient location on the floor inside your tent and then connect the other end of the duct to the closest vent. Secure the duct by tightening the vents drawstrings and organize all your cords and plug your fan in. If you have a probe, place it near where your plants would be. Now open up a vent on top of your tent and tighten all other vents and now you have hot air getting sucked in and cool air getting blown out.
