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.

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.

Humidifier and fan broke within 3 months

I love the concept of my tent and it worked great for two cycles and then the fan broke as well as the humidifier. I have tried calling but no-one has gotten back to me. So know I am just using it with monotubs in the tent because nothing works.

We are really sorry and understand how frustrating this experience has been. Somebody from our team is reaching out to you via email now to assist you with the issue.

Bad quality

Same problem as the other lady. Plastic pulling off the zipper multiple places causing big holes. Had to gorilla tape few spots. And yes racks getting rusty should have made them stainless steel. It works but you should upgrade the quality so zipper isnt pulling off in a year

We appreciate your honesty and would love to make this right! Somebody from our team is reaching out to you via email now to assist you with the issue.

Use the video to setup unlike myself
I didn’t and had to take the top tier off to get the tent over the top (which the video shows)

It is half a day to setup
make sure you have a window vent for a 4” dryer outlet

Once it’s clean inside with isopropyl your ready to go get a co2 humidity temp sensor

Let isopropyl vent an humidity build follow wit the spawn blocks and grow

1 Year Review

I bought the Boom Room II a little over a year ago. The set up was easy. The humidifier with the in room gauge is really wonderful and works well. We have had a rolling grow in there for months on end successfully. A few notes:
1) The shelves have grown quite rusty over the past year. I think if they were plastic that would be better. Looking to replace the in room frame.
2) The zipper has separated from the clear plastic cover at the bottom. Its not a big deal, it still lines up well and does the job. Could fix it myself with a sewing machine. Just thought it worth noting the wear and tear.
3) Occasionally the humidifier seems to become overzealous and the cakes have flooded from 100% humidity. This normally happens after the power has shut off and come back on.

Thanks for the detailed feedback and for growing with the BoomRoom II for over a year! We appreciate the notes on wear and tear and will share them with the team. Happy growing!
