2×2 Grow Tent Ventilation Setup | Step by Step Guide

Using the right grow tent ventilation system is essential for the yield of your plants. Plus, proper filtration is also equally important in cleaning the air, and for odor management. 

One common question we have come across among novice growers is the 2 x 2 grow tent ventilation setup.

Well, the ideal 2 x 2 grow tent setup involves replacing the air in your grow space after every five minutes when the lights are on. 

You might also have to perform this process quicker if your area experiences high humidity or heat levels. Plus, air circulation is also crucial.

2 X 2 Grow Tent Ventilation Set Up: Passive or Active Airflow

There are two specific details you should consider about setting up a 2 x 2 grow tent including

1. Passive Airflow 

Passive airflow refers to a system common among most modern growers. These systems don’t feature an intake system. Instead, they run using an inline exhaust fan, that draws air out of the tent, thus creating a vacuum. 

It attracts fresh air using intake ports in the tent’s bottom section. Maintaining negative pressure inside a grow tent is indicative of a passive system. 

However, any negative pressure indicates the grow tent has less air pressure than its environment. 

Plus, these environments don’t require total sealing. Thus, this means the occurrence of pests is highly likely, and so is odor management.

2. Active Airflow System 

While active intake systems are common, you don’t often need them unless you own a large tent. 

Or, you also don’t need it if you are perhaps a professional grower that wants to create a high-quality setting for plants.

You may also have to invest in one if you experience high-temperature issues. Or, it might also be applicable when the intake ports at the bottom are smaller than the exhaust ports.

What is the Best Ventilation System Size for a 2 X 2 Grow Tent Set Up

We have created this simple guide to help you calculate the ideal 2 x 2 grow tent ventilation setup.

To calculate the ideal CFM, you must ensure your grow space has sufficient ventilation. The specific formulae for this process will be:

Formula: Width * Length * Height = Perfect CFM Level.

There are a few factors that impact the CFM performance of a fan. These include the length and surface area of the ducting. Using resources like a carbon filter will also impact the CFM level. 

Specifically, a carbon filter adds to the effort your ventilation system has to perform. So, consider adding up to 21% to the carbon filter’s performance.

The CFM metric level will allow you to create the ideal ventilation setup for your needs. We know some growers also like using fans and air conditioners with their grow house setups. 

It’s why we recommend using a sealed room for the best results.

You can set up your 2 x 2 grow tent ventilation system in various ways. The specific approach you use depends on the specific way you have set up resources like lighting systems. 

Fortunately, customizing this grow tent set up to suit your needs is easy. You don’t have to connect to a reflector if you are an LED, CMH, or Fluorescent user.

Here are the possible steps to expect:

  1. Connect the inline fan to one of the additional ceiling bars with grow tents. You also have the option of using clip handles. They are perfect for hanging fans a few inches from the ceiling.
  2. Next, consider one of these two options. You can slide the inline fan over to fit into an exhaust hole. You can also connect your inline fan to the ducting, which you can integrate into a convenient exhaust hole. 
  3. Set up the carbon scrubber. Usually, they feature specialized ropes, which you can use for this process.
  4. Connect the carbon scrubber to the inline fan. Do this such that the fan can draw air through the scrubber. The other option involves using duct, or simply connecting both if they have a similar size.
  5. Determine if you have connected the components as required. Usually, air from the outside often gets to the interior sections through the intake ports at the bottom. It then ensures the ventilation process occurs as required, with air moving through the inline fans and exhaust apertures.
  6. Test your setup once again.

PRO TIP! If you plan on using a reflector, the setup of your grow house requires more detail. We recommend using a direct airflow system that moves through the reflector. It should then work to cool the bulb. 

Dealing With Heat and Humidity In Your Grow Room

Let us start with if you plan on using a traditional in-line fan and carbon filter set but still encounter temperatures that are above or aren’t suited for your needs. 

On average, seedlings require about 77 – 91ºF for seedlings and between 71 – 77ºF for mature plants. 

If the temperatures are higher than this, consider investing in alternative heat removal methods. Any temperatures above 84ºF or below 54ºF will harm your plant’s development (even if you supply additional CO2 to your grow room).

Realize that humidity controls are when you use different ventilation system types. For instance, we recommend using an “air-cooled reflector” if you use open-loop systems. 

These reflectors feature ducting ports, which you can integrate into traditional ducting systems. It also gets ventilation through a secondary in-line fan.

By removing the hot air from the lights, you will encounter an improved reduction in the average room temperature.

You can also opt for air conditioning systems, particularly in environments with extreme heat. We recommend using the mini split air conditioner because many people like it. 

Humidity control is also beneficial for your indoor grow house. Your plant will require different humidity ranges depending on its growth stage. 

We have noticed many people also like using dehumidifiers for humidity control. 

What is The Best Way of Dealing with Odor In Your 2 x 2 Grow Room?

We recommend you use a standard carbon filter because a 2 x 2 grow tent is small. Ensure you evaluate your carbon filter, and ensure it’s fully functional.

You can maintain yours through shaking because it helps expose unused carbon filters. Some growers use products like Ozone Generators and Chemical Neutralizers as alternatives.

It’s possible to combine all these methods for your grow house. However, there is only so much you can do to combat indoor smells. That is because flowering plants produce smells, depending on how well you set your 2 x 2 grow tent ventilation system.

While it’s possible to let your carbon filter run for the entire day, this can harm the air quality. 

2 X 2 Grow Room CO2 and other Ventilation Tips

If you want to improve the CO2 levels in your grow room, consider using the closed loop approach. 

That is because it’s a system that helps ensure that barely any CO2 makes it out of the grow house.

Find a technique you can use to deal with the odor and heat effectively without having to ventilate the air outside your grow room.

It’s best if we keep this process short, so we recommend you research more on managing CO2 in your grow tent. 

Ducting tips

Remember that ducting can sometimes bring light into your light-proof grow room (without the correct setup of course!)

When required, create a “u bend” in the duction. It will help prevent leaks that might compromise your ducting’s functions.

We also recommend you use a screen where ventilation ducting brings its final output to your structure.

Doing this helps to stop issues like animals and pests from getting through your system.

While this guide has evaluated all you need to know about grow house setups, there is still more you will learn along the way. 

Frequently Asked Questions (FAQ)

How Do You Put a Ventilation in a Small Grow Tent?

The best way to ventilate a small grow tent involves a few specific steps. Start by installing the cool hood and filter. Next, connect the filter,  then the hood with the ducting. Then, pull the ducting through the other side and connect the fan to the other end.
