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.
Pros
- Thick, durable PE material holds shape well inside standard tubs
- Pre-cut size saves time compared to cutting your own plastic
- Black design helps prevent side growth and supports even colonization
- Makes cleanup much easier and helps protect tubs for reuse
- 15 count pack is practical for multi-tub growers
Cons
- Runs slightly small and short in some 66 quart tubs, corners may need taping
- Sides can shift or fall inward if not secured, leaving edges exposed
- Loose fit can allow condensation to pool between liner and tub wall
The Adnee 15 Pcs Mushroom Monotub Liners are preformed black inserts sized at 19 x 13 x 4 inches for tubs up to 66 quarts. They are made for home mycology growers who want faster setup and cleaner harvests without cutting trash bags or sheet plastic.
In real use, the blackout sides help limit light to the substrate edges, which encourages more even top growth and fewer side pins. Growers also report easier moisture retention and much quicker cleanup, since the cake lifts out with the liner and the tub stays cleaner.
Each liner is made from tough PE plastic that feels thick and holds its shape well inside standard monotubs and Boomer Bin style containers. The material resists tearing during filling and harvesting, so it stands up well through multiple flushes in a single grow.
Fit is the main compromise, as some users find the liners run slightly small and short with exposed corners if not taped. If the liner is loose, condensation can collect between the plastic and the tub wall, so secure placement matters for best results.
Overall, these are a convenient, time saving upgrade for anyone running multiple tubs. If you want affordable, durable, ready to use liners that simplify growing and cleanup, this 15 pack is a practical pick.
Quantity: 15 pre-cut monotub liners per pack for daily use and replacement across multiple grows.
Dimensions: 19 inches x 13 inches x 4 inches, designed to line the bottom of standard monotub containers.
Compatibility: Fits most monotubs 66 quarts and under, including Boomer Bin style tubs with taping at corners if needed.
Material and Color: High quality black PE plastic that is tough, tear resistant and blocks light from substrate sides.
Setup: Unfold, press into clean tub, secure edges with tape, then add substrate mixture and culture to start growing.
How They Compare
Growing Space and Format
When it comes to space, North Spore BoomRoom II Automated Mushroom Grow gives you a vertical chamber with 5 reinforced racks inside 18 cubic feet, so you can stack trays, blocks and jars instead of spreading tubs across the floor. The maker describes room for up to 9x more than a standard tub setup, which helps if you fruit in waves or run several varieties at once. Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x stays focused on one vessel, measuring 19 inches x 13 inches x 4 inches to line containers 66 quarts and under, so your footprint does not change at all.
The tradeoff is scale versus simplicity for small homes. North Spore BoomRoom II Automated Mushroom Grow needs a dedicated corner with power for the mister and fan, plus clearance to open the clear door and slide trays, which can feel oversized if you only fruit one tub per month. Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x needs no extra floor space and sets up in minutes, but you stay limited to tub by tub results and manual care. For more context on footprint, see the monotub liner vs martha tent kit breakdown.
Humidity and Fresh Air Control
Humidity and airflow control is the clearest split in this monotub liner vs BoomRoom II matchup. North Spore BoomRoom II Automated Mushroom Grow pairs its Myco-Mister II with a dedicated FAE fan to hold relative humidity at 90%+ while stripping carbon dioxide, which supports thicker stipes, larger caps and fewer aborts. Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x offers no active humidification, it adds insulation to help hold stable temperature and moisture and uses a black design to block side light so growth stays even across the top surface.
In daily use, North Spore BoomRoom II Automated Mushroom Grow reduces hand misting and fanning, which helps if you work long hours or grow oysters and other airflow hungry types that stall in still air. The downside is upkeep of the mister, fan and vinyl plus tuning to avoid pooling or dry spots, and the smaller review base suggests a learning curve for new tent owners. Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x keeps your routine manual but predictable, yet you still must mist and fan yourself every day. The martha tent kit vs martha tent for mushroom article shows how active and passive moisture control differ day to day.
Setup, Harvest and Cleanup
Setup time favors the disposable option by a wide margin for beginners. With Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x, you simply unfold the PE liner, line the bottom of your clean tub, secure the edges with tape, then add your substrate mixture and culture to start growing. With North Spore BoomRoom II Automated Mushroom Grow, you assemble the frame, fit the ultra-clear vinyl, install the 5 racks, connect the Myco-Mister II and FAE fan, and place the Spore Floor bottom tray to catch runoff and protect floors from moisture.
Harvest and reset also feel very different over time. Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x gives you 15 liners per pack, so you can lift out the spent substrate, discard the liner and wipe the tub for the next run, and the tough PE resists tearing during that pull. North Spore BoomRoom II Automated Mushroom Grow asks for wiping of vinyl, racks and tray between flushes to manage spore dust and mineral film, while its negative pressure design helps filter air before it leaves the tent but does not remove cleaning. If you dislike frequent deep cleaning, the tent will demand more of your time than liners.
Build Materials and Daily Reliability
Materials reflect how each product is meant to be used in the home. Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x uses high-quality PE that is safe, reliable and resistant to tearing, with a black finish that blocks light from the sides to limit side pins and keep top fruits even. North Spore BoomRoom II Automated Mushroom Grow uses heavy-duty ultra-clear vinyl over a structured frame so you can monitor pin sets without opening the door, plus reinforced racks and a bottom tray that contains drips and simplifies floor protection.
Neither material is maintenance free, so plan for light care with either choice. Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x can still puncture if you drag it over sharp tub latches or pack substrate with too much force, so keep a spare liner ready even with 15 in the box. North Spore BoomRoom II Automated Mushroom Grow shows condensation and spore dust quickly on its clear walls and can develop zipper stiffness or mister scale with hard tap water, so gentle wiping and fresh water matter. You can compare other chamber builds in the Monotubs, Martha Tents and Fruiting Chambers archive before you decide.
Which One Should You Get
Choose North Spore BoomRoom II Automated Mushroom Grow if you want to fruit several trays, blocks and jars at once with less hand misting and fanning. You have a spare corner you can dedicate to an 18 cubic foot tent, you grow varieties that need steady 90%+ humidity and constant fresh air, and you enjoy watching progress through clear walls while the mister and fan hold conditions. You should also be comfortable with regular wiping of vinyl, racks and tray between runs to keep the system running clean.
Choose Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x if you already own a tub that holds 66 quarts and under and you like the in-depth tub process. You can check surface conditions daily, you want to reduce side pins and lift out harvests without scrubbing, and you prefer swapping in a fresh PE liner from your 15-count pack over maintaining a mister and fan. This path keeps your setup portable, simple to store and easy to reset for the next flush without extra equipment.
Who Should Skip Both
If you are still waiting on colonized spawn, pasteurized bulk substrate or a clean inoculation space, hold off on both and focus there first. This pair is not ideal for growers who need sterile lab gear, spawn bags or pasteurization equipment, or for anyone who cannot vent humid air and wipe occasional runoff in a living space. Once your spawn and substrate workflow is steady, revisit fruiting chambers with a clearer sense of batch size and schedule.
Frequently Asked Questions
Can a monotub liner replace a BoomRoom II tent for daily growing?
Not directly for most growers. Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x improves a single 66 quart tub by adding insulation, blocking side light and easing cleanup, but it cannot add automated humidity or fresh air. If you need hands-off control for multiple racks and 18 cubic feet of space, North Spore BoomRoom II Automated Mushroom Grow is the closer fit.
Is the BoomRoom II better for mushrooms that need constant humidity?
In most home setups, yes, because its Myco-Mister II and FAE fan are built to hold 90%+ humidity while clearing carbon dioxide for healthier caps and stipes. That helps oysters and other airflow hungry types that stall in still tubs. You will still need to clean the tent and monitor trays, so expect more upkeep than a lined tub with Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x.
What tub size fits the Adnee 15 pack liners?
The liners measure 19 inches x 13 inches x 4 inches and are sized to line most monotubs 66 quarts and under. You unfold the liner, tape it in place and add substrate without stretching it tight. With 15 pieces included, you have enough for repeated grows and quick replacements when a liner wears.
