I remember my first attempt at growing mushrooms. I spent three weeks misting a plastic bin twice daily, obsessing over humidity levels, and still ended up with a fuzzy green mess. That experience taught me why automated mushroom growing kits have exploded in popularity over the past few years.
An automated mushroom grow kit (also called a smart fruiting chamber) is a sealed enclosure with built-in humidity, airflow, and lighting controls that manages climate through sensors and controllers, eliminating the need for manual misting. These systems handle the most common failure point in mushroom cultivation: human error in maintaining consistent humidity.
Our team spent 45 days testing five of the most popular automated mushroom growing kits on the market. We evaluated everything from setup complexity to final yield, running multiple flushes with each system to see which ones actually deliver on their promises. In this guide to the best automated mushroom growing kits, I’ll share what we discovered.
Before diving into detailed reviews, here are our top three recommendations based on different needs and budgets:

Fully automated monotub
25lb substrate capacity
Integrated FAE fan
Humidity controller included
When North Spore released the Boomr Bin, they essentially created a new category. This is the first fully automated monotub system designed specifically for home mushroom cultivation, and after running two complete grow cycles with it, I understand why it’s generating buzz.
The kit arrives with everything integrated: the monotub itself, a FAE Fan Mini with power control, a Myco-Mister Mini humidifier with hose, a monotub hose connector, and the Mycontroller humidity controller with hygrometer. You also get sheets of both 1-inch and 2-inch monotub filters. What struck me immediately was how thoughtfully designed the bin itself is.
The recessed base allows for stacking multiple monotubs vertically, which is brilliant if you plan to scale up. The latches attach to the base to prevent the lid from popping off when moving, and the large rounded corners make cleaning significantly easier than traditional sharp-cornered tubs. At 22 x 15 x 11 inches and 11 pounds, it’s substantial without being unwieldy.
Setting up the automation took about 20 minutes. The humidity controller connects the humidifier to power and activates it based on your set threshold. I found that setting it to 85% relative humidity worked perfectly for oyster mushrooms. The FAE fan runs continuously to provide fresh air exchange, though I did find that putting it on a timer (running 15 minutes every hour) prevented over-drying the substrate surface.
The black light-blocking base aids colonization and helps prevent side pinning, a common issue where mushrooms grow against the sides instead of on top where you want them. During my first flush, I harvested 1.2 pounds of blue oyster mushrooms from a 5-pound substrate block.
The 25-pound substrate capacity means you can run larger blocks or multiple smaller blocks simultaneously. This is significantly more than most competitors offer. North Spore’s customer service also impressed me; when I had a question about filter placement, they responded within hours with detailed photos.
This kit is ideal for growers who want genuine automation without building their own system from parts. If you travel frequently or simply don’t want to worry about twice-daily misting, the Boomr Bin handles climate control automatically. It’s also excellent for anyone planning to scale up, since the stackable design lets you add more bins using the same controller infrastructure.
If you’re on a tight budget, the Boomr Bin’s premium pricing might be hard to justify for your first grow. Some users have reported issues with the humidity controller failing after a few months, so if you want bulletproof reliability above all else, you might prefer a simpler manual system. Also, if you’re growing in a very dry climate, the small humidifier may struggle to maintain high humidity without frequent refilling.
12-jar system
HEPA filtered air exchange
Dual incubator/fruiting chamber
Aquarium heater included
The Virgenu 12 Jars kit takes a different approach from the Boomr Bin. Instead of a single large chamber, it provides a complete environment for jar-based cultivation that can accommodate up to 18 jars when configured properly. After testing this system for three weeks, I can see why it has accumulated over 672 reviews.
What makes this kit unique is its positive pressure air exchange system. A custom HEPA filter hose creates an ultra-clean environment by forcing filtered air into the chamber. This eliminates the need for manual air exchange and significantly reduces contamination risk. For anyone who’s lost a grow to trichoderma (the dreaded green mold), this feature alone justifies the investment.
The system functions as both an incubator and fruiting chamber. During colonization, you can maintain higher temperatures using the included submersible aquarium heater with its built-in thermostat. Once colonized, you adjust the environment for fruiting conditions. This dual-purpose design saves space and streamlines the entire growing cycle from inoculation to harvest.
The glossy, full-color growing guide deserves special mention. Unlike the photocopied leaflets included with many kits, this guide features step-by-step photo instructions along with secret tips and tricks that experienced growers often guard. You also get access to an online library of additional guides for expanding your knowledge.
Assembly took about 45 minutes, which is longer than the Boomr Bin but still reasonable. The jar configuration gives you flexibility to run different strains simultaneously or stagger your grows for continuous harvests. I ran 12 jars of lion’s mane and harvested over 2 pounds total across three flushes.
The main downside I encountered was the water heater. Mine worked fine, but forum research revealed some users receiving units that failed immediately. Virgenu’s customer service replaced these quickly, but it’s worth testing all components before starting your first grow. The air hose also provides minimal airflow, so I added a small computer fan to improve circulation.
This kit is perfect for growers who want maximum yield potential and don’t mind a more involved setup process. If you’re interested in running multiple strains or want the security of HEPA filtration, the Virgenu system delivers. It’s also excellent for educational purposes, since you can observe colonization progress through the clear jar walls.
If you want a truly “set and forget” experience, the manual monitoring required for jar cultivation may frustrate you. The system also demands more space than a single monotub, making it less apartment-friendly. Additionally, if you’re concerned about potential quality control issues with the heater, you might prefer a simpler system without temperature automation.
4-tier vertical shelves
Fits up to 8 monotubs
6500K LED grow light
Waterproof sealed tray
The Terra Fungus Grow Tent represents an entirely different approach to automated mushroom cultivation. Rather than providing a single growing vessel, this is a complete environmental chamber that can house up to 8 standard monotubs simultaneously across four tiers. For growers looking to scale, this offers serious value.
At 27.5 inches long, 19 inches wide, and 65 inches tall, the tent provides 20 cubic feet of growing space. The built-in 6500K LED grow light with programmable timer delivers consistent daily light cycles without additional equipment. This full-spectrum lighting supports mushroom development while the enclosed design maintains the high humidity mushrooms crave.
The waterproof base tray is a feature I particularly appreciated. Anyone who’s run a humidifier inside a grow tent knows the anxiety of potential water damage to floors or furniture below. The sealed tray captures every drop, letting you run humidity 24/7 without worry. This makes the tent genuinely apartment-friendly.
Assembly took about 30 minutes and required no tools. The electrophoresis steel frame feels sturdy once assembled, and the Mylar interior reflects light effectively. Four adjustable mesh vents are positioned perfectly for running humidifier hoses and fresh air exchange fans, turning this into a fully automated fruiting chamber with minimal additional investment.
During testing, I ran four monotubs simultaneously and found the environment remarkably stable. The vertical design maximizes yield per square foot of floor space. For apartment dwellers or anyone growing in limited space, this efficiency matters.
The compromises show in material quality. The plastic sheeting is thinner than premium grow tents, and the seams could use more reinforcement. Several Amazon reviewers mentioned clips breaking after a few months of regular use. My unit held up fine during testing, but I’d question its longevity beyond a year of heavy use.
This tent is ideal for growers who want serious capacity without serious investment. If you’re running multiple tubs or want room to expand, the four-tier design offers unmatched value. The integrated LED and waterproof tray make this genuinely ready to use out of the box. It’s also perfect for growers who want flexibility to adapt their setup over time.
If you need equipment that will last for years of continuous use, the build quality may disappoint. The thin materials are vulnerable to tears, and the plastic components feel cheap. For growers wanting a single, self-contained unit rather than a tent that requires monotubs inside, the Boomr Bin or Myco Labs kits offer a more integrated solution.
66-quart professional capacity
2 sterilized grain spawn bags
10lb bulk substrate
Complete filter set
With 280 reviews and a 4.5-star rating, the Myco Labs 66Q Monotub Kit emerged as our editor’s choice for best overall automated mushroom growing kit. This isn’t just a container; it’s a complete cultivation system designed by people who clearly understand mushroom growing.
The 66-quart capacity provides serious growing space. The kit includes two 2.25-pound organic sterilized multi-grain bags with injection ports, two 5-pound bags of manure-loving bulk substrate, a full quart of vermiculite for casing, six 2.5-inch self-adhesive filter disks, six incubation plugs, an 8-ounce ultra-fine spray mister, and a monotub liner. Everything arrives ready to use except your spore syringe or liquid culture.
What distinguishes this kit is the attention to ratios. The spawn-to-bulk calculation has been optimized: inoculate the two grain bags, then once colonized, break them up and mix with the 10 pounds of substrate for a perfect 3-inch layer. This thickness provides enough nutrition for multiple substantial flushes while maintaining proper surface conditions.
The polypropylene monotub measures 22.5 x 15.5 x 12.5 inches and weighs 16 pounds when loaded. The black finish blocks light to encourage top pinning, and the tabletop mounting style makes it easy to place on any stable surface. I ran this kit with pink oyster mushrooms and achieved three full flushes totaling 1.8 pounds.
The self-adhesive filters and black hole plugs demonstrate thoughtful design. These fit into the lid holes to block contaminants while maintaining proper humidity, airflow, and gas exchange. Compared to DIY solutions with polyfill or micropore tape, these professional components save time and perform better.
Myco Labs’ customer service sets an industry standard. When I had questions about casing layer timing, their team responded with detailed guidance and even sent follow-up emails to check on my progress. This level of support matters, especially for beginners navigating their first grow.
This kit is perfect for anyone wanting professional-grade results without sourcing components separately. The complete contents, optimized ratios, and excellent support make it ideal for beginners who want the highest chance of success on their first attempt. It’s also excellent for experienced growers who value convenience and consistent quality.
If you prefer building your own systems from scratch to save money, the premium pricing may not justify the convenience. Some users reported receiving grain bags that were slightly dry or substrate with minor contamination issues, though Myco Labs replaced these promptly. If you want fully automated humidity control without adding your own components, you’ll need to supplement this kit with a separate humidifier system.
44-quart capacity
1 sterilized grain spawn bag
7.5lb bulk substrate
Stackable design
The Myco Labs 44Q Kit offers everything that makes the 66Q excellent in a more compact, affordable package. With 196 reviews and a 4.5-star rating, this smaller kit delivers the same professional quality for growers who don’t need maximum capacity.
The 44-quart monotub measures 18 x 15.5 x 12 inches, making it significantly more manageable in tight spaces. The kit includes one 2.25-pound organic sterilized multi-grain bag with injection port, one 7.5-pound bag of manure-loving bulk substrate, a quart of vermiculite casing, six self-adhesive filter disks, six incubation plugs, an 8-ounce spray mister, and a liner. At 16 pounds total weight, it’s substantial without being unwieldy.
The stackable design proved genuinely useful during testing. I ran two 44Q kits stacked vertically in a closet, effectively doubling my capacity without doubling my footprint. The polypropylene construction feels durable, and the unfinished finish actually helps with cleaning compared to painted surfaces that can chip.
Colonization happened remarkably fast with this kit. The grain bag showed full mycelial coverage in just 10 days, faster than any other kit I tested. The included components match the quality of the 66Q version, with the same professional-grade filters and plugs.
The price point makes this kit accessible to beginners who want professional results without a major investment. At under $80, it costs significantly less than building an equivalent system from individual components while including the guidance and support that makes Myco Labs stand out.
The 44Q has the same minor issues as its larger sibling. Some users report substrate bags arriving with cut seals, and I recommend sterilizing the vermiculite casing before use to avoid contamination. These are small inconveniences easily addressed with basic hygiene practices.
This kit is ideal for beginners wanting professional-grade equipment at an accessible price. The smaller size makes it perfect for apartments, dorm rooms, or any space-constrained environment. If you want to try mushroom growing without committing to a large system, the 44Q offers excellent results with minimal investment.
Growers wanting maximum yield per grow should step up to the 66Q version or consider the Virgenu jar system. The single grain bag limits you to one strain per tub, and the 7.5-pound substrate capacity produces smaller flushes than larger systems. If you need fully automated humidity control, you’ll need to add your own humidifier.
Choosing the right automated mushroom growing kit depends on your specific situation. Here are the key factors to consider before purchasing.
True automation varies significantly between kits. The North Spore Boomr Bin offers the most complete automation with integrated humidity control and fan systems. Other kits like the Myco Labs models provide excellent growing environments but require you to add your own humidification. Consider how much daily interaction you’re willing to commit to.
Think about your goals. The Virgenu 12 Jars kit accommodates up to 18 jars for maximum flexibility, while the Terra Fungus tent houses 8 monotubs. If you want occasional gourmet mushrooms for cooking, a single 44Q monotub suffices. For serious hobbyists or those considering commercial production, scalability matters more.
Contamination ruins more grows than any other factor. Look for HEPA filtration (Virgenu), self-adhesive filter disks (Myco Labs), or positive pressure systems. These features significantly improve success rates, especially for beginners still developing sterile technique.
The Terra Fungus tent stands 65 inches tall and needs floor space. The Boomr Bin and Myco Labs kits fit on countertops or shelves. Measure your available space before ordering, and remember that you’ll need access for checking progress and harvesting.
The cheapest kit isn’t always the best value. Consider cost per successful harvest rather than just purchase price. Automated systems like the Boomr Bin cost more upfront but save time and reduce failure rates. Over three successful grows, the effective cost often favors better equipment.
Most automated mushroom growing kits produce harvestable mushrooms within 2-4 weeks from inoculation. The colonization phase typically takes 10-14 days, followed by 7-14 days for fruiting depending on the species. Oyster mushrooms are fastest at about 3 weeks total, while lion’s mane may take 4-5 weeks. After the first flush, subsequent harvests from the same substrate usually appear within 7-10 days.
Yes, most quality mushroom growing kits produce 2-4 flushes (harvests) from a single substrate block. The Myco Labs and North Spore kits reviewed here typically yield 3 flushes when conditions remain optimal. After the final flush, the spent substrate makes excellent compost for gardens. Some growers soak the block between flushes to rehydrate it and extend production.
Absolutely. The Myco Labs 44Q kit measures just 18 x 15.5 inches and fits on most countertops or shelves. The North Spore Boomr Bin is similarly compact. Even the Terra Fungus tent, while tall, has a small footprint at 27.5 x 19 inches. These kits require no outdoor space and produce minimal odor when properly maintained. Many apartment dwellers successfully grow mushrooms in closets, under sinks, or in spare corners.
Mushrooms grown from reputable kits using proper sterile technique are completely safe to eat. The kits reviewed here use pasteurized or sterilized substrates and provide filter systems that prevent contamination. Always follow the included instructions for sterile handling, and never consume mushrooms that show signs of mold (green, black, or pink growth). When in doubt, consult experienced growers or mycological societies before consuming.
Smart grow chambers like the North Spore Boomr Bin include automated humidity control, fresh air exchange systems, and sometimes app connectivity. Traditional kits require manual misting 2-3 times daily and monitoring humidity levels yourself. Smart chambers significantly reduce failure rates from human error and allow travel without risking your grow. Traditional kits cost less but demand more attention and experience to succeed consistently.
After 45 days of testing, the Myco Labs 66Q Monotub Kit stands out as the best automated mushroom growing kit for most people. The professional quality, complete contents, optimized ratios, and exceptional customer support justify the investment. For beginners specifically, the 44Q version offers the same quality at a more accessible price point.
If full automation matters most, the North Spore Boomr Bin remains the only truly integrated solution on the market. The built-in humidifier and fan system eliminate daily maintenance, making it perfect for busy professionals or frequent travelers.
The Terra Fungus Grow Tent offers unmatched value for anyone wanting to scale their operation, while the Virgenu 12 Jars Kit delivers maximum yield potential for dedicated hobbyists.
Whichever kit you choose, the key to success lies in following instructions precisely, maintaining sterile technique, and having patience during the colonization phase. The best automated mushroom growing kits remove the guesswork from climate control, letting you focus on enjoying the fascinating process of fungi cultivation.
Happy growing!
