If you are deciding on monotub liner vs Martha Tent Kit for your home grow, you are looking at the Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x on one side and the North Spore BoomRoom II Automated Mushroom Grow on the other. One is a low lift tub upgrade, the other is a tall automated chamber that takes over humidity and airflow for you. The real choice is not about which is better in general, it is about batch size, hands on time, and how much space and automation you want. This comparison breaks down those tradeoffs so you can match your fruiting setup to your goals, and you can explore more ideas in the Monotubs, Martha Tents and Fruiting Chambers guide.
As of September 2026, we evaluated both options side by side on capacity, climate control, materials, and daily upkeep using only the maker provided specs and rated feedback. We focused on what matters for indoor mycology, which is stable humidity, fresh air exchange, ease of cleaning, and how each system fits in a lived in home. If you want a quick orientation before you buy, think of liners as improving the tub you already run, while a Martha style tent replaces scattered tubs with vertical growing space.

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 Capacity and Footprint
The North Spore BoomRoom II Automated Mushroom Grow gives you vertical scale with 5 reinforced racks and 18 cubic feet of growing space, which the maker positions as up to 9x more mushrooms than a standard tub setup. The Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x works in the opposite way, it fits inside containers 66 quarts and under with a 19 inches x 13 inches x 4 inches form to improve the tub you already own. If you want to stack trays, blocks, and jars in one corner, the tent uses height to save floor area. If you run a single tub on a shelf, the liners keep your footprint small without adding furniture.
You will feel the difference most when you plan your next few harvests with the North Spore BoomRoom II Automated Mushroom Grow versus the Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x. The tent suits a grower who wants continuous production across multiple levels and can leave a chamber set up in a spare corner. The liners suit a grower who works in small batches and prefers to tuck everything away between runs. The tradeoff is commitment, the tent needs dedicated floor space and ongoing care, while liners limit total canopy to what your current tubs can hold. For more context on sizing a fruiting space, browse the fruiting chamber collection before you decide.
Humidity, Airflow and Spore Control
The North Spore BoomRoom II Automated Mushroom Grow is built to hold Relative Humidity pinned at 90% plus using an integrated Myco-Mister II paired with an FAE fan for fresh air exchange, which helps support thicker stipes, larger caps, and fewer aborts. The Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x takes a passive approach, it provides an extra layer of insulation to help hold stable temperature and humidity around the substrate and uses a black design to block light from the sides for more even growth. In practice, the tent actively manages the climate for you, while the liners reduce side pinning and moisture loss but still leave misting and fanning to you.
Spore and moisture handling also separates the North Spore BoomRoom II Automated Mushroom Grow from the Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x in daily use. The tent is designed to run negative pressure to filter spores before they escape and includes a Spore Floor bottom tray to catch runoff and protect floors, which matters if you grow oysters or other heavy spore producers indoors. The liners do not filter air, they simply line the tub to make the microclimate more stable and cleanup simpler. The con is upkeep, the automated system needs refills, wiping, and attention to the mister and fan, while the liner route needs consistent manual care to avoid dry surfaces or stale air.
Build Quality, Materials and Durability
The North Spore BoomRoom II Automated Mushroom Grow uses ultra-clear, heavy-duty vinyl so you can monitor pin sets without opening the door, plus 5 reinforced racks meant to hold trays, blocks, and jars. The Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x are made from PE material described as safe, reliable, tough and resistant to tearing for plant growing use. Rated feedback reflects the difference in scope, the tent holds 4.1 out of 5 from 12 reviews, while the liner pack holds 4.0 out of 5 from 121 reviews, which suggests broader familiarity with the simple consumable and a smaller but generally positive base for the larger system.
Durability means something different for the North Spore BoomRoom II Automated Mushroom Grow compared with the Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x. The tent is a long term piece of equipment, but vinyl shows condensation, needs regular wiping to stay clear, and zippers and seams need gentle handling to avoid leaks. The liners are consumables, even with tear resistant PE they can puncture if snagged on a rough tub edge and you will replace them over time, though you receive 15 in the pack for daily use and replacement. If you dislike replacing plastics, the liner cycle may bother you, and if you dislike wiping down a tall chamber, the tent may bother you.
Setup, Daily Routine and Cleanup
Setup for the North Spore BoomRoom II Automated Mushroom Grow is positioned as plug-and-play Martha style growing without duct-taping humidifiers to bins, with engineered spacing and airflow ready out of the box. Setup for the Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x is manual but simple, you unfold the liner, line the bottom of the container, secure the edge with tape, then add substrate mixture and spores or liquid culture to start cultivation. The tent asks more from you up front in terms of placement, leveling racks, and learning the humidity and FAE rhythm, while the liners ask more from you every day in terms of observation and hands on adjustments.
Daily routine and harvest cleanup show the same split between the North Spore BoomRoom II Automated Mushroom Grow and the Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x. With the tent, you spend less time fanning and more time checking trays through the clear walls, refilling humidity supply, and keeping the Spore Floor tray clean. With liners, you lift the lid, check surface conditions, mist or adjust airflow as needed, and enjoy easier post-harvest cleanup because the substrate pulls away without scrubbing the tub. If you enjoy close daily contact with a single tub, liners feel rewarding, and if you prefer to manage several projects at once, automation feels calmer.
Which One Should You Get
Choose North Spore BoomRoom II Automated Mushroom Grow if you want to grow more in less floor space and you are ready for the higher-end pick with powered humidity and FAE control. You are a good match if you run multiple trays or blocks at once, grow oysters or medicinal varieties where spore control matters, and you have a corner that can stay humid without disturbing the household. You can see the full system here: North Spore BoomRoom II Automated Mushroom Grow. For help placing it among other enclosed options, compare it inside the Monotubs, Martha Tents and Fruiting Chambers hub. You should not buy it if you move often, lack a stable spot with power, or only fruit an occasional small tub.
Choose Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x if you already own a suitable tub 66 quarts and under and you want an affordable refresh without new equipment. You are a good match if you grow in modest batches, value simple storage, and do not mind handling misting, lid flips, and airflow yourself for better control. You can find the liner pack here: Adnee 15 Pcs Mushroom Monotub Liners-19″ x 13″ x. The 19 inches x 13 inches x 4 inches size lines most common tubs, and having 15 pieces on hand means you can swap in a fresh liner after harvest. You should not buy it if you expect automation, need vertical capacity, or want to fruit many containers at once.
Who Should Skip Both
Both of these options are not ideal for growers who need a fully sterile lab workflow, an outdoor bed setup, or a large commercial fruiting room with washable walls and drains. If you only grow outdoors, work with logs or garden beds, or you need stainless surfaces and strict environmental controls, neither a tub liner nor a home Martha style tent is the right choice. In that case, pause and define your space, species, and cleaning needs before choosing any chamber.
Frequently Asked Questions
Can a monotub liner replace a Martha tent kit for indoor growing?
No, a liner improves moisture stability and cleanup inside a tub you already own, but it does not add capacity or automated humidity and fresh air exchange. A Martha style tent adds vertical racks, active misting, and FAE to support multiple trays at once. Choose based on whether you need better tub performance or a larger automated space.
Is the North Spore BoomRoom II Automated Mushroom Grow good for beginners?
It can be good for a committed beginner who wants guidance from automation and has room for an 18 cubic feet chamber with 5 racks. You still need to learn sterile technique, substrate prep, and harvest timing, the tent mainly reduces fanning and humidity guesswork. If you prefer to learn on a single tub first, start with liners and upgrade later.
Do the Adnee monotub liners fit my monotub?
The liners measure 19 inches x 13 inches x 4 inches and are sized to fit containers 66 quarts and under, which covers most common home tubs. You unfold the sheet, press it to the bottom, secure with tape, and trim any excess if your tub runs small.
