Consistent fresh air exchange is essential for healthy indoor mushroom cultivation. The FAE (Fresh Air Exchange) Fan II helps move stale, CO₂-rich air out of your growing environment while introducing cleaner air to support vigorous fruiting.

Designed for the BoomRoom Martha Tent and other mushroom grow chambers, this efficient ventilation fan improves airflow without requiring a complicated control setup. Better circulation helps reduce stagnant pockets of air and supports a more stable fruiting environment.

The integrated on-unit controller makes it easy to adjust fan operation based on your chamber’s needs. Use the FAE Fan II to establish either a positive-pressure or negative-pressure system, depending on your ventilation configuration and filtration requirements.

For indoor growers, managing fresh air is a practical part of dialing in humidity, airflow, and surface conditions. The FAE Fan II works alongside a humidifier and other chamber equipment to create a more controlled setup for fruiting blocks, monotubs, and Martha-style grow tents.

Its compact, purpose-built design fits naturally into North Spore’s cultivation systems and is suitable for beginners building their first automated chamber or experienced growers refining environmental control. Proper installation and filtration should be selected according to the needs of your specific setup.

Whether added to an existing grow chamber or used as part of a BoomRoom system, the FAE Fan II provides the adjustable air exchange needed for a cleaner, more consistent mushroom-growing environment.

Powerful, Quiet Fan

Excellent product. This small 4" inline fan is powerful, yet relatively quiet. I have it fitted to a North Spore Nocbox to create a positive pressure clean space. I couldn't be happier with the results.

Thanks so much, Jake! We really appreciate the kind review. The team is here if you ever need anything.

Best customer service ever

My Exhaust fan stopped working. I sent an email On Saturday around 8 AM and by 9 AM I received an email indicating they were sending me a replacement at no charge. Best customer service ever.

Thanks so much, Daniel. We love to read reviews like this! It makes what we do all the more worth it.

Best variable control FAE fan, but older models prone to rust

It's surprisingly hard to find a good FAE fan that has the control levels this one does. Absolutely any amount of air you want to push is possible, from very very light to move mist to full bore after cleaning. Spotted a bit of rust on the metal bits, but my model has been in use for over a year non-stop in near max RH, so it's to be expected and likely addressed in future/current versions.

They replaces everything that was defective tent back up running smoothly as it should be! Love this company everything even their grain spawn is worth the purchase never had problems with contamination with their grow bag!

Martha Tent v1

I got this fan with my 1st martha tent kit and it worked great. After my first few grows, It had become pretty well neglected but clean up was pretty easy when it was finally time to upgrade. Im excited to use it with the new martha tent set up where itll be much easier to handle and adjust being outside of the tent on the floor. Better for clean up too! Its been the most durable item out of the whole v1 tent kit.
A+

Thanks for the great review, Hawa! We really appreciate your support.

Thank you for such quality products!

I’m using the fan for my fruiting chamber and as a beginner I’ve been trying to get the parameters correct. The fan has been amazing! I’ve over saturated with moisture a few times and it’s just been a perfect constant throughout the process. Additionally it’s extremely quiet which is a huge bonus. Thank you all for offering such great quality products!!!!!

PS. You’re all in one SHROOMTEK bags are the fastest colonizing grow bags that I’ve found from any company so far.
