Top 5 Must Have Fans For Grow Tents

Fans are one of the most important things you will need when setting up your grow tent. They will help keep the air circulated and moving, preventing mold and pests from harming your plants.

The Different Kinds Of Fans Needed For A Grow Tent

But before you go out and buy these fans, it's important you know which fan to get for what.

Depending on the size of your grow tent, you may need anywhere from 4 to 16 small oscillating fans.

Some fans will give your plants air movement, to help strengthen branches, while other fans can be put near the bottom of your plants to prevent pests from breeding in the soil. These fans can be anywhere from 6 to 12 inches in width. You should place these fans at the corners and in the middle of your grow tent. This will help maximize the airflow and ultimately provide the best results.

The Difference Between Inline And Exhaust Fans

Then there are inline/exhaust fans, which are meant to move air in and out of the grow tent. You will need an exhaust fan to take the old air out of a grow tent and release it elsewhere, either in your home or outside, that depends on where you want it to go. You don't need an inline fan for a grow tent, since grow tents usually come with open holes on the side to let new air in.

The only time you will need an inline fan is if you want no open holes in the grow tent, instead, you place an inline fan at the opening to cover it. This will ensure fresh air gets in the grow tent, and none goes out, only through the exhaust fan. And the exhaust fan will need to be connected to a carbon filter to clean the air of debris, particles, and smells.

Why You Need Fans For Your Grow Tent

Therefore, when all is said and done. You will have complete control over where the air goes in and out of your grow tent. Keep in mind you will also need a carbon filter connected to the exhaust fan to filter air out of the grow tent. The carbon filter will get rid of any smells or particles, and will ultimately clean the air being taken out.

Having an exhaust fan will also lower the humidity in your grow tent. So always make sure you have the exhaust fan at the correct setting, so you don't get either too little or too much humidity build-up.

So, now that you know why you need these fans and what their purposes are, let's get into the top 5 fans I highly recommend you get for your grow tent.

Top 5 Must-Have Fans For Grow Tents

5. The Best 6inch Fan

This little fan comes in handy when you need air movement in a specific area of your grow tent. It has 2 modes, slow and fast. Just simply clip it or hang it and it's ready to go. I recommend you get at least 4 of these, one in every corner, to ensure proper airflow.

4. The Best 6inch Fan For Pests

Placing a fan on the floor aimed at the bottom of your plants will prevent small flying pests from invading your plants. Especially when you are growing multiple plants. This fan is overall the best option and is even portable and rechargeable.

3. The Best 12inch Fan

This is the fan you are going to need if you are growing in a grow tent bigger than 5ft by 5ft.

It can be modified for grow tent use.

Just take off the back of the fan (3 screws), and remove the metal bracket, (careful they are super sharp), and drill a 1/4 inch hole through the hanging bracket and tent pole. Put the bracket back into the backing of the fan and install it on the pole with a lock nut, or use some thread locker then install the fan onto the pole.

2. The Best 4inch Inline Fan

This inline fan is great for bringing new and fresh air into your grow tent. It circulates the air outside and brings it in. You can also connect this fan to a filter before it goes into your grow tent to ensure the air being brought in is not contaminated.

1. The Best 6inch Exhaust Fan

This is one of the most important things you will need for your grow tent, it is essential. This exhaust fan will take the old air out of your grow tent and move it elsewhere. You will also need a carbon filter to go with this fan to clean the air being taken out. Also, make sure the carbon filter you choose is the same size as your exhaust fan.

Depending on the size of your grow tent, you may need a smaller or larger fan, I chose the 6inch because it's an all-around good size for most grow tents. If you are growing in a grow tent bigger than 4ft by 4ft, then I recommend you get an 8inch or bigger.
