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.

Whether you choose to grow from trays,fruiting blocks, jars,all-in-one bags, or evenmonotubs, 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.

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.
