Size is important!

One of the most important features that you need to look out for is the size of the carbon filter you will be using. For different sizes of grow rooms, you will be needing different carbon filters as well.

What size carbon filter for 10×10 room?

Preferably for a 10×10 grow room, a 6-inch carbon filter will be perfect to keep any unpleasant odors or gases away from your plants.They ideally have a 400CFM rate on average, which can maintain suitable air flow within your grow tent without any hassle.

What size carbon filter for 4×4 tent?

Ideally for a 4×4 grow tent, a 4-inch carbon filter will be the most suitable for your need. It will keep you grow tent smelling nice and clean with no odor build up.But if you are using a HPS grow light that produces more heat compared to LED lights, then 6-inch carbon filter will be the best option for you as higher heat production requires better cleansing of the air within the tent.

What size carbon filter for 5×5 tent?

For a 5×5 grow room or grow tent the best size for a carbon filter will be 6 inches. This will maintain a smooth flow of air within your grow room, with no odor or harmful gas build-up over time inside your grow room.

What size carbon filter for 3×3 grow tent?

3×3 grow tents will require a relatively small carbon filter, thus a 4-inch carbon filter will be the best option for this case. It will keep your grow room fresh and healthy, both for your house and your plants.

When do you need a carbon filter in your grow room?

During indoor gardening inside grow tent, often these rooms create undesirable stench and gases within which can cause an odor problem inside your tent or even spread to your entire house.These smells can occur due to various reasons such as smelly plants such as cannabis, or it can also form due to usage of fertilizers, pesticides or other nutrients for your crops.This is when you will require a good-quality carbon filter for your grow tent to remove any gaseous impurities such as bad smell/odor, particulates, harmful gases and other gaseous substance.

Where to put carbon filter in grow room?

Ideally it is best to place the carbon filter hanging from the ceiling in the inside of the grow tent. In this way it will maximize the growing footprint of the crops, while also drawing sufficient air through the filtration system. Here, the filtration system will take in air from the inside and carry it outside to cleanse any contaminants.But in if the filter is too heavy to hang, you can also place the filter at the bed of the tent which will also function just as efficiently. But this may lead to some unwanted warm air being pulled down towards the plants in some cases, thus its best to hand the filter instead.Carbon filters can also be placed outside of the tent if there is no space available inside, but it is best to place the filter inside to avoid any unwanted noise or vibration from the filters as well as better stability.

How to install carbon filter in grow tent?

The installation of a carbon filter system may seem a little tricky at first, but it is in fact very simple and easy. The steps to set-up a carbon filter perfectly are as follows:

To set-up your carbon filter in a hanging position over your plants:

Step 1: Your grow tent comes with adjustable nylon straps. By using one of these straps hang the inline fan of the filter by placing the tapered end directed towards the exhaust gap or hole that you want to use for this purpose.

Step 2: Make sure to center the inline fan so that it is stable and balanced.

Step 3: Now take the other adjustable nylon strap and hang the carbon filter with it by placing the flange in a way that it is directed towards the inline fan. Make sure to center the filter properly for stability.

Step 4: Take a measuring tape and measure the length between the start of the filter flange to the start of the inline fan flange. Afterwards, cut a piece of ducting of that exact length using your box and wire cutters.

Step 5: By using the ducting piece you cut, properly secure one end to the fan flange by taking a ducting clamp.

Step 6: By taking the other side or end of the ducting properly secure the flange of the carbon filter. In this case it will be a stable and strong fit so you won’t be needing any clamps.

Step 7: Afterwards, take the remaining of your ducting and pass it through an exhaust hole of your liking, and then properly secure its others end to the inline fan’s tapered end by using your duct clamp.

Step 8: Finally, pass the fan power cord through the closest tent cord hole at the rear side of the grow tent, and now you are all set!

To install your carbon filter on the ground of your grow tent:

Step 1: Place your carbon filter carefully on the ground of your grow tent in a position of your liking

Step 2: Position the inline fan over the filter by directing the tapered end pointing upwards to the ceiling.

Step 3: Make sure that the flange of your fan is inside of the filter flange, and then secure it in place using 1 to 2 wraps of strong foil ducting tape.

Step 4: Pass the ducting through a grow tent ventilation opening of your choice.

Step 5: Lastly, pass the fan cord through the closest cord hole at the back of your grow tent and your carbon filtration system is set!

To set-up your carbon filter outside of the tent:

Step 1: Place the carbon filter outside of your grow tent in any place you like but keeping in close proximity.

Step 2:Position the inline fan over the filter by directing the tapered end pointing down towards the floor.

Step 3:Strongly secure the fan to your filter using 1 to 2 wraps of strong foil ducting tape.

Step 4: Connect the ducting to the fan by using your duct clamp.

Step 5: Finally pass the ducting through a ventilation hole on the tent of your choice, and your grow tent is all set to smell fresh!
