Why a grow tent?

Grow tents are designed to make indoor gardening easy. In the 21st century, most people prefer growing plants indoors and there are a handful of reasons why a grow tent is the top pick for many.

Easy control

It is easy to grow plants in a controlled area and a grow tent is just the right definition of a controlled area. In a grow tent it is easy to monitor the progress of the plants. Unlike outdoor farming, growing plants in a grow tent will allow you to easily detect whenever something is not right with the plants.


An alternative for a grow tent would be a greenhouse. Well, as much as there is nothing wrong with a greenhouse, a grow tent is affordable.

Why do you need fans in a grow tent?

It is one thing deciding on the best fans for grow tent and another knowing why you actually need the fans in the first place. From basic third grade science, the three basic needs for plants to grow are air, water, and light. One would wonder, why have fans in a grow tent yet it isn’t a basic need? The truth is, fans in a grow tent is not a luxury but more of a necessity.

Here are the reasons why you need a fan in a grow tent


Unlike animals, plants use both oxygen and carbon dioxide through two reverse processes, photosynthesis, and respiration.

Photosynthesis occurs in the presence of light and uses carbon dioxide to make food; this explains why it is refreshing sitting under a tree during the day. Respiration, on the other hand, is the reverse of this and uses oxygen excreting carbon dioxide. Fans are necessary to create a breeze of air and increase the oxygen flow in the tent.

Prevent burning of the plants

Light is included as one of the basic need for plants to grow. In a grow tent there will be no sunlight to illuminate the plants instead, artificial lights are used. Well, the problem with this is that some lights eliminate heat that can be too much to the extent that it burns the plants.

A fan is necessary to cool down things and prevent the plants from burning that would otherwise damage them.

Maintaining stable humidity levels

If you know a thing or two about growing plants it is no brainer to assume that you know humidity is essential for plants growth. So what is humidity? This is the ability of the air to hold water. Some plants thrive in high humidity whereas others require moderate humidity.

When it is too hot in a grow tent, this will drain plants off moisture through respiration. Yet another reason why you need services of the best fans for grow tent. Fans help maintain stable humidity levels without draining the plants.

Prevent the development of molds and fungus

The last thing you want is fungus and molds in a grow tent. This would mean that plants would have to complete for oxygen and nutrients. Molds and fungus thrive in warm and humid conditions. Having fans in a grow tent ensures that temperatures are regulated preventing the growth of molds, fungus, and algae.

Pest control

Having the best fans for in your grow tent acts as pest control. Most pests can’t stand having cold air blown over them leave alone the noise from the fan

Convenient for growing a few plants

Most people practicing indoor gardening don’t want large scale farming. On the contrary, all they want is a place to grow a few plants. Grow tents come on different sizes and shapes making it easy and convenient to decide on the appropriate size given the number of plants to be grown.

Prevent the spread of bad odor

It is not always that you grow something that is odorless. For instance, what if you are growing marijuana and you don’t want your nosy neighbors to know about it? A grow tent is ideal in such a case when you don’t want the pungent smell spreading all over the room.

Features that draw the line between the best fans for grow tent and the ordinary

In a market with over 100 brands producing fans for grow tent, it is not easy deciding on the best fan worth purchasing. This should not be the case anymore, we have highlighted a few unique features that you should look for when searching for the best fans for grow tent

Noisy or silent

We can all agree to one thing, there are super annoying loud fans. Given the fact that the grow tent will be located indoors, you might want to opt for a rather quiet fan. The good thing is there are more than enough silent fans to choose from in the market today.

Different speed settings

As much as things need to be cooled down in a grow tent, sometimes when the fan is rather too fast this isn’t a perfect recipe for maximum yields. Some fans have different speed settings which are ideal in regulating both humidity and temperature in a grow room.

Adjustable head

Some fans have a rather fixed head that won’t move nor get adjusted easily. Well, this is not a problem but what if I told you there are fans with an adjustable head? Fans with adjustable heads are convenient to use since you can have the head face in just any direction. That’s not all when on some fans will move round in 360 degrees.

Power supply

All fans run on the power that’s not a debatable issue. However, they vary when it comes to the power supply. Some have a rechargeable battery, others can be charged through USB whereas the vast majority are corded and have to be connected directly to power for them to function. This is not quite a deal-breaker as long as the fan functions just fine.

Strong and adjustable clip

The fan has to be clipped somewhere in the grow tent. Purchase a brand that has clips and stands as part if accessories

Use and Operate Effectively

It is not yet done, you still need to know to use and effectively operate a grow tent fan.


After purchasing then, you are required to install it in the grow room. Installation is easy hence no need to call an expert. You are an expert at your own caliber. Depending on the size of the grow tent you might need more than one fat in most cases one is enough. Determine a suitable location to install the fan then install it.

How it functions

Once installed, connect to a power supply then turn on the fan. Most fans have an option to control the speed, set it as desired depending on the number of crops and temperature.


Deciding on the best fans for grow tent should be no longer overwhelming. Well, at least not after reading a review of the best fans in the market today. Our top pick for this was AC Infinity Cloudline T6 Inline Duct Fan.
