Top 3 Picks: Best Inline Fan For Grow Room
Things To Consider When Buying Inline Fans For Grow Rooms And Grow Tents
Inline fan is an important and useful component of any grow room’s air circulation system. As it can be used to deliver clean air to the plants, it also cleans the air as it exits from the exhaust.
When connected with a filtration system, it even provides better performance as it filters odor and pathogens from the air within the grow room. While investing in an inline fan for your grow room is an excellent decision, not all of it may fit your specific requirements.
Listed here are some considerations to make sure you are buying the right inline fans for your specific grow rooms.
Fan Rating And Speed
One important consideration when buying inline fans for your grow room or grow tent is the fan’s speed or rating. The rating or speed of the fan dictates how much air circulates within the system.
If you’re looking to have more air circulation in your grow tent, buying a fan with higher speed and rating setting would be ideal.
For you to compute the ideal speed and rating for your fan, you simply use the formula L x W x H of the grow room/tent multiplied by 20 – this will be the total amount of air within an hour.
Compatibility With Carbon Filters
Inline fans work best in filtering air if they are used with carbon filters. When buying inline fans, make sure that it is compatible with the carbon filter that you are using. Check the components, connectors, washers and hole diameter.
The size of your inline fan is likewise an important consideration to make. It should come with a size that perfectly fits and matches the size of the air duct and the growing area.
While bigger sizes of inline fans could provide more power and air in the grow room’s air circulation system, it may not be suitable for light to medium air system settings.
One thing that I personally do not like about inline fans is that they can be noisy during operation. Fortunately, with constant improvements and better material alternatives, it now produces much tolerable noise and sometimes even creates almost zero noise during operation.
A good way to check the noise levels out of your inline fan is to test it out before making a purchase.
Ease Of Use And Installation
Of course, you would also want an inline fan that is easy to use and does not require complicated set up, installation or any rigorous preparation. Make sure that you understand how it works and how to perform maintenance when needed.
With regards to installation, you may want to have your inline fan with helpful accessories that can make the installation much easier and faster. Among those accessories and tools, you want to have with your inline fan include mounting brackets, base, extra bolts or screws for customized setups, and others.
Speed Control Settings
Not all the time you will require your inline fan to work at its top speed. Sometimes you will also need it to run a little slower especially if you’re only looking to filter the air from your grow room. Besides, having your inline fan run at its top speed all the time can cost you on your electricity bill.
This is why it is also an ideal choice to go for inline fans with speed control settings. The more speed settings you can have for your fan, the more flexibility you can have out of it for different purposes.
