How to Set Up Carbon Filter in Grow Tent


A carbon filter is a filtering technology that employs activated carbon to remove pollutants from water or air. Water or air passes through a carbon filter, and as it moves through the carbon, the pollutants stick to the carbon particles.

Carbon filters are used to purify water and clean the air, but they do incredible job at getting rid of the smell of cannabis plants in a grow tent or greenhouse. They are often used in the exhaust system of a car.

Taking the example of marijuana plants, carbon filters will not change the smell of the marijuana plants, but they will keep the plant's smell from leaking out of the grow room. In the grow room, a fan blows the plant's smell out and across a carbon filter, which traps the smell. This way, the plant's smell isn't released outside.

The basics of carbon filtration:

Carbon filtration is also used to remove water additives or toxins from a hydroponic nutrient solution that isn't good for your plants. The shape of carbon filters has led to them being referred to as can filters in some circles, which also happens to be the brand name of a company that manufactures this type of equipment.

Carbon filters are also employed in various types of filtration, such as gas masks, some air conditioners, and odor-proof baggage/luggage.

Carbon filters are very effective, durable, and last a long time. The filters come in a variety of sizes and shapes, including can (cylindrical) styles and flat styles, to fit the grower's exhaust system, no matter what type of system they have.If you want to know more about carbon filters in detail, you can read this article:What are Carbon Filters?

How To Set Up a Carbon Filter In a Grow Tent?

When you're growing plants inside, you don't want them to make your house smell bad. Unless you're growing something that smells good and lovely. Even potentially harmful scents and pollutants from soil, fertilizers, and the plants themselves can be produced during indoor gardening. In order to get rid of the smells and other pollutants, you should put activated carbon filters in your air flow system. To control and clean the air in your grow tent, in this article we will show you how to set up a carbon filter. 

Depending on the size of your grow business, even smaller rooms or tents that draw fresh air from the surrounding area into the room to carry away hot, stale air and an input fan to bring in fresh. When you grow plants in an enclosed space, you need to put the fan at the bottom of the room so that the dense air that gathers there is taken in by the fan. As the warm and moist air rises to the top of the growing space, the supply fan will blow it out. This will make sure that the plants get a lot of fresh air, and the contaminants will stay outside the growing space.

Depending on how you set up, it may not be necessary to have the air that goes through the carbon filter outside of your growing area. Instead, the filtered air should be brought right back into your growing area. You can achieve this by attaching the carbon filter to the intake side of the fan using a rubber coupler or ducting and positioning it inside the growing area without ducting the fan's output out of the grow. It will keep "cleaning" the air around the growing area to get rid of smells.

Importance of Carbon Filter In grow tent

Activated carbons have a lot of tiny, porous pores that are good at soaking up things. Carbon air filters are used for a lot of things. However, the following are the principal applications of this product in a grow tent:

Removes Odor

Some crops have a smell that some people find unpleasant, like cannabis. If you want to grow plants in your grow tent, you'll need to filter the air instead of just ventilating the space. You should put a carbon air filter on both ends of your airflow channel, especially your outflow. Most of the smell will be removed by this method before the stale air (oxygen) is thrown out into the outside world.

Removes Airborne Diseases and Pathogens:

When you start to grow plants in a grow tent, it turns into a whole ecosystem over time. Microorganisms will also be born in this ecosystem, but they will be very small. It can be hard for the plants to get rid of these things, or "pathogens." These microorganisms, especially those that are airborne, will be killed if the air is always filtered with a carbon air.

Absorbs Smog in the Air

There are many dangers associated with smog-related pollution when it is combined with fog and vehicular and industrial pollutants. In a grow tent, sometimes the air filter can get smog from the outside air. Smog will even burn the leaves of your plants over time. Even smog can be removed from the air by activated carbon filters.

There are many ways to set up a carbon filter in your grow tent. This is just one of them, and it's very simple to do. To do it, you will need some equipments;

1.The first thing you need to do is find a carbon filter that fits your grow room.

  1. You'll need aluminum ducting or other ducting to connect your filter to the fan, so you can keep your air clean.
  2. Duct clips for making sure there is an airtight seal between your fan and your filter.
  3. Use duct tape to make the seal even stronger.
  4. The right fan for your grow tent.

First, put both the fan and the filter inside your grow tent.

Make sure the filter is on one side of the tent and the fan is on the other near the vent. Ducts should run

from the filter to a fan, then from a fan to outside of the tent. Keep the fan moving air outside from inside the tent.

Secondly, put both the fan and the filter outside your grow tent.

The directions say to put the filter on the inside of your tent near the vent. Fans should be pulling the air outside from inside the tent.

Third method, placing the fan inside and the filter outside the grow tent

The directions say to put the fan on the inside of your tent near the vent. Run ducting from the fan to the filter outside of the tent through the vent. Keep the fan moving air outside from inside the tent.

The fourth method is to put both the fan and the filter outside of the grow tent.

Make sure that you put the ducting on the top of your grow tent near the exhaust port. Run the ducting from the inside of the grow tent to the fan outside of the tent through the vent. When you connect the fan, make sure it is pulling air outside from inside the tent.

How to keep your carbon filter clean?

Most of the time, the cleaning process must be done at least once a month to keep things clean. Regular use causes thick layers of wastes or dust particles to build up. The sticky wastes can also make the air smell bad.

Filters should be changed on a regular basis to keep contamination from getting into the water. If the filter material or cartridge is not used for a long time, it should be changed.

 Let's see how to keep the carbon filter clean.

The outside of carbon air filters should be cleaned with a dry sponge or your hand.

They are often like lint traps on clothes dryers. Carbon chemical filters are often like that. Gather lint from a carbon filter in the same way that you would clean a lint trap, and then do the same thing with it.

Never moisten a carbon air filter throughout the process. Before you do anything else, you can tap the carbon air filter on a solid surface to get rid of the dust and dirt that has been stuck in it. Then firmly grab the carbon air filter and vigorously wave it through the air. It's time to shake the filter until you can no longer see dust coming out of the filter. To clean the frame of the filter, you can run a sponge over its outside. This will remove any dust or dirt on the frame


Using carbon filters is a good idea for anyone who grows plants because they remove chlorine and other chemicals from water but don't take away the minerals that plants need. Carbon filters are also used in homes, aquariums, garden ponds, and wastewater treatment. This is why they are also used in these places and indeed a great product or method in today's age. Carbon filters needs to be cleaned regularly and deeply so that there is no dirt left. Moreover, they are affective in removing toxins and even smog which is common in cold weather.
