This best carbon filter for indoor grow tents guide has got you covered! There are hundreds of options that are available, but this does not mean that you can settle with just any other option. Keep on reading and learn from the things that I will be sharing in the rest of this post.
What is a Carbon Filter and How Does it Work?
A carbon filter has the primary function of removing impurities in the external environment, which is vital when it comes to odor management. It can exist in various forms, such as a carbon block water filter. Those that are mentioned in this post, on the other hand, exists in the form of carbon air filters.
When you are growing indoor plants, including cannabis, you will use fertilizers, nutrients, and pesticides, among other things. While it can indeed bring some benefits, it can also lead to a foul odor. The unpleasant smell can be strong and can reach even outside the grow tent. This is the reason why you need to invest in the best carbon filter for grow tent.
More than odor management, a carbon filter will help in the elimination of compounds that can cause diseases in plants. Through the ventilation that it provides, air-borne pathogens can be kept out of the grow room, promoting the best state of health of your plants.
Carbon filters can exist in two main forms. The first one is solely a carbon filter. The second one is more versatile – a carbon filter fan combo. In the case of the latter, the carbon filter can also function as an inline and exhaust fan.
Often in a cylindrical form, a carbon filter makes use of active carbon or simply a carbon that has been oxygen-treated. It is equipped with a highly-porous charcoal where air would pass through. As it passes through, the odor is also trapped, and hence, there is no foul smell that could escape. This is important when growing cannabis in a discrete manner.
How to Choose the Right Size of Carbon Filter?
As you try to narrow down the choices, one of the first things that you need to take into consideration is the size of the carbon filter. If it is too small for the grow room, it might be unable to deliver effective performance.
To choose the size appropriate for the grow room, look at the dimensions. Multiply the length and the width of the grow tent, which will give you the calculation of the area. Once the area is computed, multiply it with the height of the grow room. After this, you will have the total volume or cubic feet. The result is the CFM.
What are the Other ways to Get Rid of Odor in a Grow Room?
While the use of a carbon filter is one of the most effective odor management solutions, there are other things that can be equally promising, including those that will be briefly mentioned below.
- If you are growing cannabis, one of the best solutions that you might want to consider is the use of odor absorbing gels. The unwanted odor will be attached to the gel, and in turn, it will be replaced with a more pleasant smell.
- Check for leaks in the exhaust. If there are leaks, odor will be able to escape easily from the grow tent.
- You can also consider the installation of odor neutralizers. However, if you are growing marijuana, do not use odor neutralizers during the flowering stage as they can negatively impact the quality of the buds.
How to Take Care of your Carbon Filter?
To keep the carbon filter in its peak condition and to make it last longer, here are some of the most important things that you have to keep in mind:
- To clean the filter, all that you have to do is to remove it from the grow room. Take it to an open space where you can clean it easily. Shake it vigorously to remove any trapped dirt or dust. Spray water. Submerge it in a water with mild soap for about 15 minutes. Rinse and allow it to dry completely before putting back in the grow tent.
- You have to dry the activated carbon under the heat of the sun to make it last longer.
- Before using the filter, it is also necessary to have it vacuumed first. This is important to remove the excess carbon prior to its use.
- After reaching the maximum capacity, do not try to have it spared. Using it beyond its lifespan will compromise its performance.
How to Set-up Carbon Filter in a Grow Room?
To make sure of the best performance of the carbon filter, here are the things that you need to do:
- Take off the carbon filter from the packaging and get ready for its installation. Place it on the exhaust, making sure that it is securely attached.
- When installing the filter, make sure to connect it to the intake side of the exhaust.
- An air-tight seal should be created between the fan and the filter. If there are gaps, it won’t do an effective job in filtration.
- Provide support to the filter to make sure that it won’t fall. One of the best ways to do this is to use a rope. Choose the desired height and see to it that it is not too close or too far from the plants.
How to Choose the Best Carbon Filter for Grow Room?
With the tons of the options that are available, here are some of the most important factors to consider to make sure that you will end up with the right decision:
- Material: The main material that is used in the construction of the carbon filter is important not only in terms of durability but also performance. Premium materials can be more expensive, but they are sure to be worth your money.
- Versatility: If you want the best value for the money, choose one that is multifunctional. With this, you might benefit from choosing a product that acts not only as a carbon filter, but also as an inline or exhaust fan.
- Price: It is tempting to end up choosing a product that comes with a cheap price. It may be easy on the wallet, but when performance is compromised, it will be useless. With this, try to find the perfect balance between quality and cost.
- Warranty: This is important if you want to have peace of mind. Within the warranty period, you can be guaranteed that it is free of defects. Otherwise, the manufacturer has got you covered, making sure of your highest level of satisfaction.
