Best Inline Fans for grow tents 2019 : Buying Guide

  • Size of the growing area:

The first and the most important factor that would influence your decision is the size of the growing area. The size of the growing area would give you a fair idea of the amount of air circulation that is required. Different sized fans come with different air circulation rates. The fan should be chosen to meet the optimal circulation of the space. There is a formula that can help in deciding the capacity of the fan that should be opted for. But for that we need to know about the CFM of a fan and what it stands for along with the dimensions of the room.

  • CFM:

“CFM” stands for cubic feet per minute. The CFM in an inline fan determines the amount of air that the fan can move in a minute. The air volume is measured in cubic feet and CFM can be considered to be a measure for rating the fans. As mentioned earlier, there is a formula for finding out the capacity of a fan that you should look for or to be precise the CFM rating in a fan that you should look for which can provide optimum level of circulation to your growing space. The length multiplied by the breadth multiplied by the height (all in feet) of the grow space if further multiplied by 125% (1.25) will give you the CFM rating of the fan that would be appropriate for you. The extra 25% that is added in the formula is to give some room for the resistance that comes from carbon filters or ducting. Though this is the ideal formula, you can sometimes do away with it and settle for a fan with a CFM rating one third of the value as the air in the indoor grow room has to be exchanged in every 1-3minutes. But this is recommended only if you have a tight budget.

  • Heat of the lights:

Another factor that has to be considered while determining the capacity of the inline fan you are opting for, is the type of grow lights that are being used. Some grow lights like the HID generate more heat and would require much heat dissipation compared to LED grow lights that are almost cool and generate very less heat. If you are using grow light that generate more heat it is always advisable to go for an inline fan with a higher CFM rating.

  • Diameter of the fan:

The inline fans come in various sizes. They range from 4” to 16” in diameter. The fan size that you should choose will depend not only on the size of the grow space but also upon the opening in the grow space that can accommodate the fan though the most popular ones are the ones in the range of 4”, 5” and 6”. Sometimes even a converter can do the trick instead of opting for a brand new fan of a different size.

  • Sound from the fan:

Sound from the fan or the noise that it makes can be a bit of a concern. Some fans make really loud noise and may turn out to be irritating if you have a small house. So you should opt for fan which claims to have whisper quiet operations. Latest fans are equipped with innovative technologies so that they do not make much noise.

  • Material :

The material with which the fan is made will influence the durability of the fan. Most fans are made of steel. Some even have a powder coating to protect the fan from external elements.

  • Installation:

Most inline fans do not require professional help for their installation. So it’s wise to choose a fan which has an user friendly design and comes with a mounting bracket along with an instruction manual so that you can have a hassle free installation.

  • Warranty:

Warranty is an important factor so that in case there is a malfunction within a warranty period you can always reach the manufacturers for repair or replacement. Choose a fan that at least has a years warranty to back it

CONCLUSION:

Selecting the inline duct fan for your grow tent shouldn’t be much of a problem with the buying guide and the list of the best inline fans at your disposal. You need to make some quick calculations regarding the size of the grow tent and the capacity of the inline fan that is required for effective ventilation of your grow tent and then figure out the one that best suits your needs. A good inline fan may be one of the most under-rated requirements when you think of a hydroponic garden but it cannot be done away with and it will definitely facilitate your yields to a major extent.
