Your Questions, Answered

Not at all! The BoomRoom II was designed for beginners — it comes with detailed step-by-step instructions, labeled parts, and requires only basic assembly. Most users have it up and running in under an hour, with no special tools or experience needed.

Up to 100 lbs! The tent’s five shelves can hold up to 20 pounds of substrate or four fruiting blocks per rack, making it ideal for both small hobbyists and serious cultivators seeking higher yields.

While DIY setups can work, the BoomRoom II saves you time and frustration by offering a proven, reliable system that’s already optimized for ideal humidity and airflow. It’s built from durable materials and tested by experienced cultivators — so you can focus on growing, not troubleshooting.

Maintenance is minimal — just refill the humidifier and wipe down surfaces occasionally. The automated humidity and fan system does the hard work for you, so you can spend more time watching your mushrooms thrive instead of constantly monitoring conditions.

Yes! The BoomRoom II has a compact footprint (about the size of a small wardrobe) and runs quietly, making it perfect for basements, closets, or spare rooms. Its clean, zippered design also keeps moisture and spores contained for easy indoor use.

Grow Bigger Flushes

Growing bigger flushes of gourmet edible and medicinal mushrooms has never been easier with our new and improved BoomRoom II Automated Mushroom Grow Chamber. Whether you choose to grow from trays, fruiting blocks, jars, all-in-one bags, or even monotubs, this self-contained, fully-automated incubation and fruiting space gives you full control of environmental conditions critical for mushroom growth, including humidity level and fresh air exchange. Cultivate your favorite fungi and some peace of mind knowing your grow is in good hands with the BoomRoom II.

Built to Last

The BoomRoom II has been built with the high-quality materials so you can keep growing time after time. We know you're buying this thing to pump out some serious mushrooms and the BoomRoom II can handle whatever you throw at it. Our zippered tent design is crafted with double-stitched seams and reinforced plastic materials (for bottom, top, and side coverage), guaranteeing longevity and stability. Moreover, the reinforced plastic creates a diffused light effect, mimicking natural conditions to promote healthy mushroom growth.

Optimal Environmental Control

The BoomRoom II excels in maintaining the ideal cultivation environment. Humidity is introduced from the top, creating a conducive atmosphere for mushroom growth, while a fresh air exchange fan system filters out CO2 from the bottom, ensuring a constant supply of fresh air. For those seeking additional automation, a float valve is available separately, allowing the humidifier to be linked directly to a water source for hassle-free refilling.

Excellent kit

This is an excellent quick and simple to use kit for newbies or seasoned growers who just want a nice clean set up. Got it unpacked and running in like 15 min, set up is super easy. It’s been running on auto pilot for a few weeks now and I just harvested a lovely lions mane flush from my first round of cultivation.

Great so far

It has been great. I do think that there should be an app for the controls. I went on a trip for a weekend and worried about the system while I was away. It would be great if it was autoset to turn on and off when needed.

Havnt purchased was just wondering . How many grow bags does the tent hold at 1 time

Boom Room 2

it's not that bad but there are a few things left to be desired! the humidifier seems to be overkill for the size tent, even trimming the setting back there's pools of water. the humidifier feed pipe needs to be on an angle to help prevent the water droplets from dripping out into the tent and could run back down the pipe. The steel shelves rust out within weeks. i wish there was a better filter option for the fae fan as the provided ones are barely large enough to wrap around the fan then try to get it secured in the tent feed tube. i think we can do better Team!

Thanks for the detailed feedback, Sam! We really appreciate you taking the time to share what’s working and where there’s room for improvement. We’re always looking for ways to improve the Boom Room, and feedback like this is incredibly helpful.

Great tent and ventilation, but the included humidifier is oversized

The BoomRoom II tent itself is well designed. The enclosure is sturdy, and the included rubber floor mat is a nice addition for protecting against runoff or accidental pooling. The FAE fan performs as advertised and provides plenty of ventilation.

The included humidity controller initially malfunctioned, but North Spore’s customer support team responded quickly and sent a replacement. While waiting, I used an AC Infinity Controller 79 during empty tent commissioning.

My only significant complaint is the included humidifier. It has far more output than this tent volume requires, and even its lowest output setting is too powerful for precise control. I spent several days trying to dial it in with the Controller 79 set with no humidity buffer. I eventually had to lower the activation point to 86% RH. Once the tent reached range, even corrections lasting only one or two seconds could cause the humidity to continue climbing to 94% to 96%.

The resulting pattern was a classic bang bang sawtooth control cycle. The controller activated the humidifier at approximately 86%, too much mist entered before the reading caught up, and the remaining mist caused a large overshoot. The tent then took approximately 45 minutes to drift naturally back to 86% before repeating the cycle.

The first attachment shows the testing of the included humidifier and demonstrates this pattern clearly. Humidity ranged from 86.0% to 96.0%, with a 91.4% average. The average sounds acceptable by itself, but it hides the repeated 10 percentage point swings. Multiple days of adjustments produced essentially the same pattern.

Because this happened while I was targeting the recommended 90% to 95% fruiting range, I did not attempt to test lower humidity ranges, where that degree of overshoot would be even more difficult to manage.

I replaced the included humidifier with an AC Infinity Cloudforge T3 and was able to dial it in within the first 15 minutes. The second attachment shows the testing of the T3. During that test, humidity ranged from 88.2% to 92.4%, with a 91.1% average. Continued testing showed that this tighter pattern held consistently. Instead of producing one large humidity spike followed by a long decline, the T3 makes smaller, more frequent corrections and maintains a much narrower range.

Overall, the tent, floor protection, and FAE system are very good. I would recommend that North Spore include a smaller variable output humidifier or provide substantially finer control at the lowest setting. The included humidifier can easily generate enough humidity, but it is difficult to regulate precisely in a tent this small. It may come in handy if I ever move to a larger tent, but I wish I could have returned the humidifier separately. Since I purchased the system on sale as a package, I assumed returning only the humidifier was not an available option.

I also want to make it clear that North Spore’s customer support deserves an A. The team responded quickly and promptly replaced the malfunctioning controller. My criticism is specifically about the humidifier being oversized for the BoomRoom II, not the quality of the tent or the customer service.

Thanks for the detailed feedback! We really appreciate you taking the time to share what’s working and where there’s room for improvement.

Boom Room II

The boom room II is amazing, it gives me much more control over some of the conditions for my mushrooms than my set up i had before, the setup was easy and the ultrasonic humidifier is awesome. My first flush of pink oyster were delicious. I would like to see improvements on the drip tray at the bottom of the tent however the benefits far outweigh that. Love the product thanks.

Thank you so much for your review, Emanuel! We appreciate your feedback and we're thrilled to hear you're loving your BoomRoom II. Happy growing!

Doing great

This is my first grow tent. I'm new to this hobby and still learning. It took a couple of days to get my setting correct but I think I have it dialed in. The racks do rust. I just hope that they last over time. The only other problem is that I wish that there was a little more extra room between the shelves. Overall I am having fun with this new hobby.
