How Inline Fans Help Your Crops Grow

In most cases, grow rooms often deal with the issues of ventilation. One of the reasons is because of the lighting system involved. While it provides the plants with their needed sustenance, it also heats up the surroundings. As too much heat gets introduced into the grow room, it can end up burning your plants and crops. This is why it’s essential to have a proper ventilation system that can supply fresh, cool air to the plants while at the same time, remove excess hot air from the grow room.

Plants grown indoors are vulnerable to excess heat. As a solution, inline fans should be installed to provide proper airflow

It will also help you remove CO2 depleted air and create good airflow across all your crops. The best inline fans for grow room ventilation are also the best solutions for maintaining your grow room’s temperature to prevent burning your crops.

Why Proper Ventilation Is Necessary For Your Grow Room

Why is proper ventilation necessary for grow tent and grow room environments? Well, there are a few reasons why.

With proper ventilation, you can be able to grow healthy plants and even increase your yield

Plants that are grown in an outdoor environment are able to enjoy the cooling effects offered by light breezes, evaporation, sunshine, rain, etc. Meanwhile, in an indoor environment, we use fans for breezes and evaporation, watering systems for rain, and grow lights for sunshine. However, we tend to forget that air can freely and naturally circulate outdoors.

One of the reasons why most indoor growers fail to produce successful crops is because they lack proper ventilation

So, why do you need proper ventilation for your grow room?

  • It allows you to control humidity. Humidity is one of the factors that can hamper the growth of your crops in an indoor growing environment. As your plants emit water vapor, the humidity inside your grow room increases. If humidity level goes uncontrolled, it can lead to poor growing conditions and even the introduction of pests and diseases into your grow room. By installing an inline duct fan, it will wick away excessive moisture in your grow room, thus allowing your plants to absorb more water and nutrients.
  • It rids of excessive heat. As mentioned earlier, grow lights emit heat into your grow room environment. If too much heat is discharged, it can burn your plants and even cause the air to stagnate. With a grow tent fan, you can rid of excessive heat and introduce fresh, cool air into your grow room.
  • It controls CO2 levels. Plants require CO2 for proper growth. Without a proper supply of CO2, your plants’ growth will be limited. With proper ventilation, you can guarantee that your plants can get a regular supply of CO2-rich air in your grow room. It also removes old air from your room, which in turn leads to proper growth and increased yields.
  • It helps prevent pests and plant diseases. Without proper ventilation, the air within your grow room will stagnate. This leads to the development of airborne pests and diseases which could greatly affect your plants’ health. By providing proper ventilation from the best inline fans for grow room environment, you can maintain a constant flow of fresh air, thereby providing a comfortable environment for your plants and a less hospitable surrounding for pests and infestations.

Buyer’s Guide: How To Choose The Best Inline Fans For Grow Room Application

Now that you have an idea about the best fans in the market, let us talk about some tips and factors you need to consider when buying an inline fan. Before anything else, it helps if you choose the right size in accordance with your grow room. After all, you will need the right amount of ventilation to generate a sufficient supply of airflow in your indoor garden. If not, you’ll end up overheating your plants, which in turn can only affect their health and growth.

Without further ado, here are some things you should consider when buying an inline fan:

1. Size

You need to choose the right size that fits your grow room area. If you have a small room, a 4-inch inline fan is more than enough

The size of your preferred inline fan is important as it allows you to provide proper ventilation to your room. You need to pick the right size that fits perfectly with your growing area. While big inline fans can provide more power and ventilation, it may not be ideal for light to medium-sized grow rooms.

When we talk about an inline fan’s size, we’re referring to the diameter of their duct. If you’re going to install an inline fan in a grow tent, you’ll need to consider the size of the said tent. Or, if you plan to install your fans directly into your ducts, you need to make sure that the fans have the same size as your fans, or else you might be forced to replace your ducts to accommodate your inline fans.

2. Speed Control

In some cases, you want your inline fan to operate at moderate speed. There are also times when you have to run it a little slower, particularly if you want to filter the air inside your grow room. Also, running your fans at its top speed at all times will cause your electricity bill to skyrocket.

Speed is yet another factor to consider when choosing an inline fan. It’s best to pick fans that have several speed settings to allow you to customize the speed depending on your application

It is for this reason why you should only choose the best inline fans for grow room applications with speed controllers. The more speed settings available in your fan, the more options you can use for different ventilation purposes.

3. CFM (Cubic Feet per Minute)

CFM or Cubic Feet per Minute is the unit used for measuring the power of your fan. In other words, it measures how much airflow your fan can provide in any given room. Fans with higher CFM are ideal for bigger grow rooms or those that use HID lights for their lighting systems. Meanwhile, rooms that use LED lights can do well with smaller inline fans since they don’t emit too much heat.

Fans with higher CFM have high output. However, it also means they consume a lot of power. If you own a small-sized grow room, it’s better to look for a product with lower CFM

When shopping for the best inline fans for grow room applications, you should look for a fan that can provide you with a decent CFM measure at low power usage. Since inline fans are often small and intended for circulating air within an enclosed room, your choice of a CFM should be suited to the requirements of your growing area.

4. Noise Levels

Typically, an inline fan produces too much noise and vibrations during operation. Fortunately, with constant innovations, you can now find products that feature a very quiet and smooth operation. In fact, there are even those that create almost zero noise!

5. Ease Of Use And Installation

You wouldn’t want an inline fan that is difficult to use and comes with complicated installation and setup instructions. This is why before you even make a purchase, you need to find out if a product features easy inline fan setup for your grow room. You should also do some research and find out how inline fans work and how to carry out maintenance whenever necessary.

When it comes to installation, you should check if your inline fan comes with accessories that will help make the installation process a lot easier. Some of these accessories include mounting brackets, extra bolts, and screws.

The Verdict

One of the best inline fans for grow room application that I personally recommend is the iPower 6-Inch Inline Fan. Aside from its capability to provide excellent ventilation for a grow room setup, it’s also one of the quietest products out there.

Its durable ceramic-coated casing ensures that it can last for years, and the fact that it’s permanently lubricated means that there’s no need for consistent maintenance at all.
