AC Infinity Inline Fan Systems - Are they Worth it for Indoor Grow Tents?

Outdoors, plants leverage the mitigating effects of evaporation, sunshine, precipitation, and light breezes. The substitute for sunshine in indoor gardening is grow lights, and for precipitation, the watering systems.

Growers are conscious of these factors, but most tend to overlook that air circulates more naturally outdoors than indoors, which is crucial for plant health.

As a living system, your indoor garden needs a constant supply of fresh and cool air to thrive, and so the grow tent atmosphere is as important as the nutrients.

Growing crops indoors means that you have chosen to provide the ideal conditions for your plants and are responsible for creating the right artificial environment. This means monitoring and maintaining the proper humidity, CO2, and temperature.

When plants are younger, they need higher temperatures to absorb moisture in the air. The root system is in development, and the plants depend on leaves through stomata to capture moisture.

But this changes as they move through vegetative and flowering stages, and cooler temperatures are necessary. That means you must know and maintain the right conditions through the different stages of plant life.

This entails maintaining the ideal temps, humidity, and airflow, which come with the fringe benefit of keeping mold, pests, and mildew at bay.

You see, plants transpire and release excess water into the grow room environment. In the absence of a reliable ventilation system, they become soggy, and their vulnerability to mold, spider mites, mildew, and harmful insects increases.

Keep in mind that damp topsoil is a good breeding ground for pests.

Nonetheless, good ventilation slows down the reproductive cycle of the pests and insects, and a steady breeze makes it tougher for bugs to establish their colonies on leaves. Shaky and windy ground is never a good home for anyone, even critters.

A sound ventilation system blows away the transpired water, allowing more absorption and nutrients pull up through the root system. But there's more.

The system maintains an optimal CO2 level.

A grow tent is an enclosed system where carbon dioxide that plants use for photosynthesis can quickly run out, which is usually for beginner growers. This spells doom for the plants.

Certainly, fan systems play a critical role in your grow room's ventilation and plant health. But you have to choose the suitable fan systems to get the best harvest.

AC Infinity Inline Fan Systems

The technology used inside the grow tents, especially lighting, has made significant strides in the last decade.

But we cannot say the same for inline systems, which seem to have been stuck somewhere along the way.

What is currently available is loud and lacks modern features such as adjustability; not all but most.

AC Infinity stands out from the crowd with fan systems that have come of age by keeping pace with technology and innovation.

The brand started with high-end stereo fans and has now taken clever cooling solutions to indoor gardening.

AC Infinity fans have advanced control features and a modern design. Their most impressive features yet include automated speed controls and quiet operation, which has been lacking for a long time.

Other AC Infinity Products

Apart from the inline fan systems, AC Infinity deals in a wide range of products in various categories. They include component cooling, HVAC and home cooling systems, grow ventilation, hydroponics, and grow accessories.

AC Infinity Inline Duct Fans

Inline duct fans or exhaust fans expel hot and humid air from your grow space. Slight changes in humidity and temperature can be catastrophic for your plant health, and this negates your objective of a successful and profitable yield.

Since the indoor grow environment is always hotter than the outside, having an extractor fan to bring in cooler air and regulate the temperature is critical.

In passive intake ventilation systems, exhaust fans play an additional role of a vacuum to bring in fresh CO2-carrying air from outside.

AC Infinity inline duct fan is in a class of its own, leveraging CLOUDLINE Series technology in a budget-friendly package.

The fans are designed to:

  • Distribute heating and cooling
  • Sweep away perspiration from the leaves
  • Ventilate hydroponic grow rooms and
  • Exhaust odors

The B-Series models have an intelligent controller, timers, cycles, minimum fan speed, custom transitions, and temperature programming.

The current crop of grow tent fans are raucous, and uncomfortable, but that is not the case with AC Infinity.

AC Infinity's inline duct fans feature a flow design with high static pressure and PWM-controlled EC motors for a quiet operation.

This technology also ensures the fans are energy efficient.

Things to Consider When Buying an Inline Fan System

  • Size of Inline Fan: the amount of needed airflow is dependent on the size of your grow space. Getting the fresh air from the outside in exchange for the stale air is vital for a successful indoor garden, a figure measured through cubic feet per minute.

To determine the airflow needed in your grow space, calculate the volume in cubic feet. Since most grow tents come in inch measurements, you need to do a simple calculation to convert them to feet.

Multiply the length with width and height to get the volume of the grow space.

The volume you get from the calculation is also the grow space CFM. But you also need to factor in accessories used inside the space.

  • Other accessories: increase the base CFM based on the efficiency percentages of your accessories.

The fan's performance reduces when you add carbon filters and ducting. This determines the size of the fan. Account for the heat output while you calculate the CFM.

The required CFM = (Grow light heat x Base CFM x Component factors)

If you have a 4 x 3 x 5 grow tent, the base CFM is 60.

If you also have a carbon filter with the efficiency rate of 50%, ducting tape 30%, silencer 20%, and grow light heat output of (≤50%) then:

The Required CFM is = (1.5 grow light x 60 base cfm x 1.5 carbon filter x 1.3 ducting tape x 1.2 silencer)

Which is 210.6 CFM.

Which AC Infinity Inline Fan Model Should I Choose?

The suitable model for you will depend on the required CFM (most important), the features you want, and your budget).


Inarguably, AC Infinity has the best inline fans based on efficiency and innovative features such as timer, temperature program, custom transitions, and quiet operation.

But apart from the innovative features, the fans are available in budget-friendly packages.

AC Infinity is also the manufacturers of the best grow tents, LED grow lights, and other grow accessories. Get the best equipment for your hydroponics under one roof, and enjoy your best harvest yet.
