Pros
- Huge interior easily handles multiple mushroom bags and culture supplies
- Effective still air design helps improve success rate for inoculation and liquid culture
- Sets up instantly with no tools and stores flat for small apartments or closets
- Transparent, wrinkle resistant material makes observation and photo documentation easy
Cons
- Plastic walls are lightweight rather than rigid, so tent can shift if bumped during delicate work
- Elastic armholes may feel snug for larger users during extended sessions
- Requires regular wiping with alcohol to maintain truly sterile conditions, not a replacement for a flow hood
The Salcod Large Still Air Box is a 38 by 20 by 25 inch portable clean workspace built for mushroom growers, home mycologists and hobbyists doing agar, liquid culture and tissue culture work. It is ideal if you lack a dedicated lab but need reliable contamination control for inoculation and transfers.
In real world use, the oversized interior easily holds several grow bags plus plates, jars and tools, so you can work without constant rearranging. The still air design plus elastic armholes helps limit airflow and contaminants, which supports higher success rates for sensitive culture work.
Construction uses clear, waterproof and scratch resistant plastic that stays wrinkle free for good visibility and easy cleaning. The elastic pop up frame opens instantly with no assembly and folds down into the included storage bag, while dual zipper doors on both sides make loading bulky items simple.
It is not perfect, as the flexible walls can move if bumped and the armholes may feel tight during long sessions. Like all still air boxes, it still needs thorough alcohol misting and careful technique, and it cannot match the active filtration of a laminar flow hood.
Overall, this is a practical, beginner friendly solution for creating a clean workspace anywhere. For home scientists who want more room, fast setup and clear observation, it offers strong value and versatility.

The North Spore Boomr Bag Monotub Refill Kit is designed to restock your monotub setup with fresh sterile substrate and spawn materials. It is built for home mycologists who already own a monotub bin and just need reliable, ready to use consumables for the next cycle.
Standout features include two 5 lb bags of manure based Boomr substrate, a 3 lb organic grain bag with injection port, buffered coco coir and adhesive filters. In real world use, growers report fast colonization and strong yields when good sterile technique is followed, with many repeat purchases.
Build quality reflects North Spore expertise, with hydrated substrate at field capacity, nutrient rich millet and wheat berries, and 0.2 micron filtration for clean gas exchange. The triple washed coco coir and spun bonded filters help maintain proper humidity and airflow throughout colonization and fruiting.
Drawbacks are worth noting, as a small number of buyers received a bag showing early contamination and one noted missing tape. You will also need to supply your own spore syringe or liquid culture, and best practice is to let bags rest a few days after shipping before use.
Overall, this refill kit is a convenient and trusted way to keep your grow going without sterilizing bulk materials at home. If you value consistency, sterile preparation and time savings, it is an excellent pick for your next monotub run.

Pros
- True plug and play automation eliminates constant hand misting and fanning
- Vertical 5 shelf layout maximizes yield per square foot in a small footprint
- Clear vinyl walls make it easy to monitor pins, canopies and harvest timing
- Built in spore containment and runoff tray for cleaner indoor growing
- Purpose built for mycology with balanced airflow, humidity and spacing
Cons
- Large 18 cubic foot tent still needs dedicated floor space plus power and ventilation
- Clear vinyl interior requires regular cleaning to prevent fog residue and buildup
- Beginners may need time to dial in humidity and FAE settings for different varieties
The North Spore BoomRoom II is a fully automated 5-rack Martha tent designed to replace messy monotubs with a controlled indoor biosphere. It is built for culinary growers, hobby mycologists and anyone ready to move from manual misting to consistent, high yield fruiting.
Standout performance comes from the paired Myco-Mister II and FAE fan system. The mister holds humidity at 90 percent plus for strong pinning, while the fan exhausts CO2 to encourage thicker stems, larger caps and fewer aborts across flushes.
The design uses a sturdy metal frame with ultra clear heavy duty vinyl and five reinforced racks offering 18 cubic feet of vertical growing space. A negative pressure layout with filtration plus a Spore Floor tray helps contain spores and catch runoff for cleaner home use.
There are tradeoffs to consider. You will need a dedicated corner with power and ventilation, and the vinyl interior requires regular wiping to stay clear. Beginners may also need a few cycles to dial in placement and airflow for their specific varieties.
Overall, the BoomRoom II is a serious upgrade for growers who want automation, scale and visibility in one system. If you want dense canopies without daily fanning and spraying, this purpose built tent is an excellent long term investment.
How They Compare
Purpose and Growing Space
Salcod Large Still Air Box Mushroom Grow Tent measures 38x20x25 inches and offers a wide, enclosed bench for agar inoculation, liquid culture work, and handling mushroom grow bags. North Spore BoomRoom II Automated Mushroom Grow takes the opposite approach with 5 reinforced racks and 18 cubic feet of vertical growing space for trays, blocks, and jars. If you need elbow room for syringes and petri dishes, the Salcod layout makes sense, while bulk fruiting favors the BoomRoom vertical design.
In practice, you will use Salcod Large Still Air Box Mushroom Grow Tent before colonization and North Spore BoomRoom II Automated Mushroom Grow after colonization. The Salcod tent uses large dual-zipper openings on both sides for quick loading of tools and samples, which suits small rooms and closets. The BoomRoom system stacks your grow upward so monotubs do not clutter your floor, a space advantage highlighted in many Martha tent setups for home growers.
Build Quality and Environmental Control
Salcod Large Still Air Box Mushroom Grow Tent is built from high-quality transparent plastic described as durable, waterproof, scratch-resistant, and wrinkle-resistant for clear observation. Its high-elasticity armholes aim to seal around different body types to limit contaminants during transfers. North Spore BoomRoom II Automated Mushroom Grow uses ultra-clear, heavy-duty vinyl over a frame, designed as a living display chamber rather than a disposable cover, so you can watch pin sets develop without opening the door.
For climate, Salcod Large Still Air Box Mushroom Grow Tent provides passive protection with no fan or mister, so you control cleanliness through technique and still air. North Spore BoomRoom II Automated Mushroom Grow pairs an integrated Myco-Mister II with an FAE fan to hold relative humidity at 90%+ while stripping CO2, and it runs negative pressure with a Spore Floor tray to catch runoff. That automation supports thicker stipes and larger caps, but it also means more surfaces to wipe down than the simple Salcod shell.
Setup, Footprint and Daily Use
Salcod Large Still Air Box Mushroom Grow Tent arrives with an elastic support frame that needs no assembly and folds into the included storage bag when you finish. The package also includes one mini thermometer and two spray bottles for basic monitoring and misting during sterile work. North Spore BoomRoom II Automated Mushroom Grow is positioned as plug-and-play, yet you still need a dedicated corner that can hold its tall, 5-rack footprint and allow access to all sides for harvesting.
Day to day, Salcod Large Still Air Box Mushroom Grow Tent asks you to sanitize your arms, tools, and interior before each session, then store it flat after you finish transfers. North Spore BoomRoom II Automated Mushroom Grow asks you to refill the mister, check trays across 18 cubic feet, and empty the bottom tray to protect floors from moisture. If you move often or share a small apartment, you will appreciate the foldable Salcod design, while a stable home grow room favors the always-on BoomRoom.
Consumables, Repeat Harvests and Owner Satisfaction
North Spore ‘Boomr Bag’ Monotub Refill Kit bridges these two tools by supplying what both workflows consume over time. It includes two 5 lbs Boomr Bag sterile manure substrates, one 3 lbs organic sterilized grain bag with injection port and 0.2 micron filter patch, two sheets of 1 inch and 2 inch self-adhesive filters, and 3.4L of triple-washed Myco Coco. You still need to provide your own spore syringe or liquid culture, and the kit is built to keep colonization and incubation going without mixing your own bulk substrate.
Owner feedback shows different expectations for each approach. Salcod Large Still Air Box Mushroom Grow Tent holds a 4.4/5 rating from 332 reviews, which reflects its simple, reusable role for clean work. North Spore BoomRoom II Automated Mushroom Grow holds a 4.1/5 rating from 12 reviews, while North Spore ‘Boomr Bag’ Monotub Refill Kit holds a 4.3/5 rating from 9 reviews, so the automated system has a smaller base of early users. As the higher-end pick, the BoomRoom makes sense when you plan stacked, continuous harvests up to 9x more than a standard tub setup, while the Salcod tent suits repeated inoculation days with minimal upkeep.
Which One Should You Get
Choose Salcod Large Still Air Box Mushroom Grow Tent if you focus on agar transfers, liquid culture inoculation, grain-to-bulk transfers, or plant tissue culture in limited space. You get a 38x20x25 inch clear workspace with dual-zipper access, armhole seals, and pack-flat storage that fits closets and spare bedrooms. It is the practical match when your bottleneck is contamination during inoculation rather than humidity during fruiting, and you want a reusable station you can set up in minutes.
Choose North Spore BoomRoom II Automated Mushroom Grow if you want to fruit blocks, trays, and jars in one vertical chamber with controlled humidity and fresh air exchange. You get 5 racks, 18 cubic feet of space, integrated misting and FAE, plus negative pressure and a runoff tray for cleaner home use. It is the stronger match when you grow oysters or other high-yield varieties and want steady pinning without constant manual fanning, especially when paired with a refill supply of grain and substrate.
Who Should Skip Both
If you only run one small tub per season on a shelf, this pair is not ideal for your needs and will add more gear than value. You would be better served by browsing simple tub designs in the fruiting chamber guides and focusing on clean spawn and field-capacity substrate. Both reviewed options assume you either do frequent sterile transfers or run continuous fruiting, and they are not recommended for growers without stable space, time for cleaning, and a plan for spore management.
Frequently Asked Questions
Can I use the Salcod still air box as a fruiting tent like the BoomRoom?
You can hold colonized bags inside it briefly, but you should not rely on it for pinning. Salcod Large Still Air Box Mushroom Grow Tent has no mister or FAE fan, so humidity drops quickly when you open the dual zippers. North Spore BoomRoom II Automated Mushroom Grow is built to hold 90%+ humidity and exchange air, which is what pins need to develop fully.
Does the North Spore BoomRoom II replace the Boomr Bag refill kit?
No, they serve different stages and work best together for continuous grows. North Spore BoomRoom II Automated Mushroom Grow provides the fruiting environment with racks, misting, and airflow. North Spore ‘Boomr Bag’ Monotub Refill Kit provides the consumables, including manure substrate, grain bag, coco coir, and filters, and you still need to add your own culture.
Which option in the North Spore BoomRoom vs boomroom tent debate is better for beginners?
If you are new and worried about contamination, start with Salcod Large Still Air Box Mushroom Grow Tent to practice clean transfers in a forgiving, portable space. If you are new and already have clean spawn and want bulk harvests, North Spore BoomRoom II Automated Mushroom Grow simplifies fruiting with automation. Most beginners benefit from learning sterile technique first, then scaling to a Martha system once grain runs stay clean.
