Hands-down, the most amazing approach to control the smell of your growing cannabis plants is to use a carbon filter. When installed rightly as an accessory of an exhaust system, a carbon filter won’t just keep the smell of cannabis from getting outside, but it will also keep it from smelling up your home. A carbon filter can be more powerful than some other technique for controlling the smell, and it will not alter the smell of your cannabis.
What are Carbon Filters?
Carbon filters play a significant part in any indoor growing environment. Besides growing tents, these gadgets are also found in air conditioners and heaters, where they help catch pollutants while letting clean air go through.
With regards to developing cannabis, the “pollutants” in the center are fragrant terpenes. Even though the carbon filters can affect the taste and the potency of cannabis, they also release a strong smell.
These filters feature layers of active carbon, a type of carbon treated to features tiny, low volume pores. These filters highlight layers of initiated carbon, a type of carbon treated to highlights little, low volume pores. These small openings increase the surface area of the filter, giving more space for the filtration process to occur and chemical reactions to take place easily.
How Do Carbon Filters Work?
Carbon filters work on the principles of adsorption—the bond of molecules to a surface—to clean the terpene-rich air found in grow tents.
Since the activated carbon has a significantly enhanced surface, it fills in as the ideal substance for the task. To explain things to you in an easy way, a single gram of activated carbon attributes to a surface area of 3,000m²!
To guarantee terpenes go through the filter, cultivators need to make a vacuum in the grow space. Exhaust fans that match the carbon filter’s necessities will drag air through the device and out of the grow tent.
A proper suction will compel the entire terpene-rich air through the filter, keeping any from leaking out of the sides of the grow tent.
As the pungent smells go through the filter at the right speed, the activated carbon will catch airborne terpenes while allowing different molecules to go through, keeping the pungent smell of cannabis from leaking out of the grow tent.
By attaching the duct to the outlet of the exhaust fan, cultivators can direct the pungent smell to go out the window.
How Long Does A Carbon Filter Last?
The life of a carbon filter is a very important aspect to consider while choosing an air filter or air purifier to use while controlling smells in indoor cannabis grow house. Cannabis grow tents are loaded with a variety of different airborne pollutants that will pollute the quality of air indoors and lead to odor issues in the surrounding areas of the site.
VOCs radiated by plants can add to smog, and when these VOCs blend in with nitrogen oxides, they can make a significantly more hazardous poison in the air.
When VOCs are present in the air, they tend to taint the air quality and emit an odor. VOC terpenes might end up creating a strong marijuana odor in the air. When used in a climate like a cannabis grow room/tent, the carbon air filters will probably not comprise the longest life span because of the substantial degrees of toxins found all around that the carbon filter might adjoin to its media surface.
As the media surface of your carbon filter starts to load up with the toxins and odors, the filter will be completely full, which will re-release the collected pollutants on the filter back to the air.
How Often Shall One Replace The Carbon Filter?
When carbon filters are installed into the cannabis grow room, these filters will work to collect the odors onto the filter until the filter media is full. When the carbon filter is too full even to consider catching and eliminate toxins from the airspace, the filter will start to release toxins from the carbon filter into the air.
The activated carbon technology is usually compared to a sponge, as both of them collect materials through adsorption, and once it reaches its maximum limit, they begin to release the materials captured back into the surroundings.
This process might happen with a carbon filter as well. However, it could be a week, a month, or whatever, depending upon the temperature and the humidity.
Where Does One Put The Carbon Filter?
Carbon filters mostly suspend just beneath the roof of a grow tent. Follow the following steps to place them perfectly:
- Connect your filter to an exhaust fan that includes a viable CFM (Cubic Feet per Minute) and duct width.
- Secure the two devices properly by using an airstrip or duct tape.
- Hang up the setup to the rooftop handles of the grow tent as high as possible.
- Then, connect the ducting to a power source of the exhaust fan and secure it with a duct tape.
- Feed the opposite side of the ducting through the hole on your grow tent.
- Position the ducting outlet close to an open window or ventilation shaft.
Well, well, well. Now that you are all set with the basics, how about you master the art of making your own Carbon Filter at Home?
Steps To Make A Carbon Filter at Home:
Here is the detailed guide for creating a DIY Carbon Air Filter for your grow room. For an idea, the setup here is for a 4-inch ducting system. If you intend to make a bigger carbon filter, the supplies and the procedure of making it is the same. You simply need materials to be bigger.
1. Make sure the size of the inner and outer mesh match each other.
The mesh pencil holders will act as the skeletal casing of your carbon filter. Along these lines, it is rudimentary that the size of the two cross-sections fit over one another. The following are the basic things that you must take into consideration:
Height: The smaller holder should be at least three-fourth of the height of the bigger one.
Breadth: The measurement of the smaller holder should be equal to the diameter of the ducting. You can do this to guarantee tight-fitting.
Distance: The space between the bigger holder and the smaller holder inside should be around 12-24mm.
2. Set up penetrability of the internal and external cross-sections.
Both of the pencil holders used are porous as a result of their mesh construction. In any case, its bottom may not yet be. Around there, you may have to drill holes into them to guarantee that the air can go through on all sides of the holder.
Mostly, these cross-section pencil holders comprise a thin metal material. They will, in general, be not as hard, so be extra cautious when drilling some holes into them. Drilling tools that are as small as 5/32 may turn out best for this.
3. Insert both of the cross-sections in different socks.
You need to use one sock for each pencil holder. Strech up the sock opening and insert the cup in the bottom part first. Pull the socks up to have complete coverage on all sides. Repeat the same thing with the other pencil holder.
4. Fill the external mesh with activated carbon.
Fill the external lattice with initiated carbon.
Be cautious in pouring the activated carbon in the external cross-section of the bigger pencil holder. Top it simply off to half of the length. Ensure to use a very finely grounded activated charcoal, particularly when you use a rather small carbon filter. It will make sure that the filtration process is efficient.
5. Secure the activated carbon between the cross-sections.
To prevent the carbon from pouring out and get wasted, put the inner mesh on top of the carbon layer inside the bigger cup. Pull the sock of the bigger cup all the way up for the coverage of the smaller cup.
By now, the activated carbon must be all sealed in. Be cautious in flipping the setup. It will help for an even circulation of the carbon everywhere on the hole between the two meshes. In any case, you also need to leave an even layer of carbon between the bottom surfaces of the cup.
Voila! You are all now set for installing a Carbon Filter in your grow room.
