Intake Fan

It’s like a breath of fresh air for your grow tent, bringing in active air and all that lovely CO2 to keep your plants healthy and happy. Intake fans are typically less powerful than inline fans and are positioned low down in the tent to help bring in the cool fresh air.

Inline Booster Duct Fans

This is like the personal trainer of fans – it’s all about boosting your ventilation system and making sure you’re getting the most out of your equipment. Inline booster duct fans are used to increase the airflow in the ducting system. The fans are typically installed in line with the ducting and can help to increase the efficiency of the ventilation system.

plant growing in tent

Here’s a step-by-step buying guide to help you choose the best fan for your grow tent:

  1. Determine your grow tent’s size: The first step in choosing a grow tent fan is to determine the size of your grow tent. This will help you select a tent fan that can effectively circulate air throughout your entire grow tent.
  2. Choose the type of fan: There are several types of grow tent fans available, including clip-on fans, inline fans, and oscillating fans. Consider your specific needs, the size of your grow tent, and your budget to help you choose the right type of grow tent fan.
  3. Consider the fan’s airflow capacity: Airflow capacity, measured in cubic feet per minute (CFM), is an important factor to consider when choosing a grow tent fan. A fan with a higher CFM rating can circulate more air and create better ventilation in your grow tent.
  4. Look for a fan with adjustable speed settings: Having the ability to adjust the fan’s speed can help you create the ideal growing conditions for your plants. Look for a fan that offers multiple speed settings. Therefore you can adjust the fan’s output to suit your specific needs.
  5. Consider the tent fan’s noise level: The noise level of a grow tent fan can be an important factor to consider. Especially if you plan on spending a lot of time in your grow tent. Look for a fan that operates quietly, so it won’t disrupt your indoor gardening experience.
  6. Look for additional features: Some tent fans come with additional features, such as built-in temperature and humidity controllers, automatic timers, and oscillation. Consider these features to help you choose the best tent fan for your specific needs.

What is the best fan for a grow tent?

The best for a grow tent is the AC Infinity CLOUDLINE T4 because it’s powerful and runs efficiently with low noise levels.

Should I run a fan in my grow tent?

Running an intake fan in your grow room will bring fresh CO2 to your plants. An exhaust fan is effective for removing the hot, humid air.

Are tower fans good for grow tents?

Tower fans are good for grow tents, as they fit well in the corner of the grow tent. Oscillating tower fans are great for circulating the air around your plants.

Do I need an oscillating fan in a grow tent?

Oscillating fans are intended to circulate air throughout the grow tent, simulating the natural wind required by plants. These fans minimize hotspots and humidity zones and encourage better stem growth in plants by uniformly spreading air.

Do fans stay on 24/7 in a grow tent?

Plants are particularly vulnerable during the seedling stage. It’s a good idea to run your fan 27/7 to maintain temperature, humidity, and fresh air for your seedlings.

How much air flow does a grow tent need?

Calculate the amount of airflow for your grow tent by the required CFM = (Grow Space Width X Length X Height) / 5. The length and course of ducting influence a fan’s CFM performance. If you use a carbon filter, this will reduce fan performance even further.
