North Spore BoomRoom II Automated Martha Tent Kit
The BoomRoom II replaces cobbled-together Martha setups with a purpose-built automated chamber that handles humidity and fresh air exchange without manual intervention. It holds five racks, giving you significantly more canopy space than a standard monotub. If you grow mushrooms indoors at any serious volume, this replaces hours of daily environmental babysitting.
Key Features
- Purpose-built automated Martha tent designed for indoor mushroom cultivation
- Automated humidity control and fresh air exchange included
- Five-rack chamber for high-yield canopy production
✅ Pros
- Eliminates DIY assembly of humidifiers, fans, and plastic bins
- Automated humidity and FAE control reduces daily maintenance time
- Five-rack capacity supports meaningful production volume
- Engineered airflow targets even canopy development across all levels
❌ Cons
- 479 dollar price point is a significant upfront investment for hobbyists
- No detail provided on replacement parts availability or warranty terms
Why We Chose It
North Spore built this system around the actual environmental requirements of mushroom fruiting rather than adapting general-purpose grow tents. The integration of humidity and fresh air exchange control into a single purpose-built unit removes the biggest failure points in DIY Martha setups. For anyone who has troubleshot a taped-together Martha rig at midnight, that engineering focus is the core value here.
Perfect For
Intermediate to serious home growers who have outgrown monotubs and want reliable automated environmental control without building a custom setup from scratch.
GROWORLD Martha Mushroom Grow Tent 5-Shelf 63in
A purpose-built fruiting tent sized at 19x27x63 inches with five full shelves and 18 cubic feet of usable space. The clear vinyl enclosure keeps humidity in while external controls free up interior room for blocks, trays, or grow kits. At $79.99 it targets hobbyists who want a dedicated fruiting chamber without building a DIY setup.
Key Features
- Clear PVC vinyl cover with reinforced woven sides and waterproof sub-floor
- Humidity and airflow controls mount externally to maximize interior shelf space
- Five full shelves in a 19 by 27 by 63 inch footprint with 18 cubic feet
- Fits monotubs, humidifiers, inline fans, and heaters without modification
- Vented design with heavy-duty materials suited for beginners and experienced growers
✅ Pros
- Five full-width shelves handle multiple fruiting blocks or trays simultaneously
- External control placement keeps the 18 cubic foot interior unobstructed
- Waterproof vinyl floor protects surfaces from condensation and spills
- Clear panels let you monitor colonization and pinning without opening the tent
❌ Cons
- At 63 inches tall it requires adequate ceiling clearance and is not truly portable once loaded
- No humidity controller or humidifier included despite the humidity-focused marketing
Why We Chose It
The external control placement is a practical design choice that most budget Martha tents skip, directly adding usable shelf depth. Five full shelves at this price point offer better volume-to-cost ratio than comparable single-shelf fruiting chambers. The waterproof base layer addresses a common complaint about moisture damage to floors.
Perfect For
Home cultivators growing oyster, shiitake, or lion’s mane who want a dedicated fruiting chamber that fits 5 to 10 fruiting blocks at once without a DIY build.
North Spore BoomRoom 4-Tier Martha Mushroom Grow Tent
The BoomRoom is a dedicated mycology fruiting structure built with heavier materials than typical greenhouse tents. It ships as a bare shell, so growers choose their own humidifiers, fans, and controllers. That flexibility makes it a solid foundation for a dialed-in fruiting setup without paying for electronics you may already own.
Key Features
- Four-tier vertical layout designed specifically for mycology fruiting
- Custom spore floor drip tray prevents mess and floor water damage
- Tubing port built in for humidifier or irrigation line routing
- Purpose-built structure engineered for indoor fruiting chamber use
✅ Pros
- Drip tray and tubing port are purpose-built details generic greenhouse tents omit
- Four-shelf vertical layout maximizes fruiting block capacity per square foot
- Heavier construction than typical backyard greenhouse frames and covers
- Blank-slate design lets growers pair any humidifier, fan, or controller
❌ Cons
- Tent only with no electronics included, total setup cost will be higher
- Limited publicly available specs on material thickness and frame gauge
Why We Chose It
The integrated drip tray and dedicated tubing port solve two real problems that growers using repurposed greenhouse tents deal with constantly: water pooling on floors and awkward workarounds for humidity lines. North Spore built this for one job, which shows in the details that generic alternatives skip.
Perfect For
Intermediate to advanced home growers who already own or plan to source their own humidifier and environmental controls and want a durable, dedicated fruiting chamber frame.

Why We Chose It
At $99.99 this kit removes the guesswork of sourcing compatible lights and timers separately, which typically adds $30 to $50 to a beginner build. The transparent enclosure is a practical detail that experienced growers will appreciate for spotting contamination early. Expandable vent ports mean the tent can grow with your process rather than becoming obsolete.
Perfect For
First-time mushroom growers who want a ready-to-use indoor setup without sourcing individual components.
LIGNAKAUVI Martha Mushroom Grow Tent 4-Tier with LED
A frosted PVC fruiting chamber that replaces the typical black grow tent with a cleaner look that fits in living spaces. The arched one-piece zipper door opens fully for unrestricted access to all four shelves, which matters when harvesting fragile fruiting bodies. At 27x19x65 inches it holds enough substrate bags for a serious home grower without dominating a room.
Key Features
- Arched one-piece zipper opens full width for unrestricted shelf access
- Frosted semi-transparent PVC lays flat for thorough cleaning between grows
- Frosted material diffuses light to protect delicate fruiting bodies
- Frosted PVC with black trim fits kitchens, basements, or living areas
- Reinforced seams and industrial-grade zippers rated for high humidity
✅ Pros
- Full-open arched door eliminates the awkward reaching and snagging common with standard zipper panels
- Frosted PVC is easier to wipe down and inspect than opaque black fabric tents
- 27x19x65 inch footprint fits standard wire shelving units and suits most home setups

- No humidity or airflow specs published, making it harder to compare against dedicated fruiting chambers
Why We Chose It
The frosted PVC construction solves two real problems: it cleans flatter and more thoroughly than fabric, and it looks acceptable in shared living spaces where a black tent would stand out. The full-open arched door is a genuine usability improvement over partial-zip designs, especially during harvest of oyster or lion’s mane clusters that catch on standard zippers.
Perfect For
Home mushroom growers who want a dedicated fruiting chamber that does not look like a grow tent and can fit in a kitchen or living area.
MOLLYAIR Martha Tent with T8 Light and Timer
A fully enclosed mushroom fruiting chamber sized at 35.8 by 13.8 by 62.8 inches, built to hold multiple monotubs alongside a humidifier and heating pad. It ships with a T8 full-spectrum grow light, a 12-hour mechanical timer, a four-tier metal rack, and a temperature and humidity meter. The 600D Oxford fabric shell and 95% reflective interior make it a functional all-in-one kit at a reasonable entry price.

The vent placement and accessory compatibility suggest deliberate design for humidity-sensitive cultivation rather than a repurposed plant tent.
Perfect For
Home growers running their first or second monotub batch who need a contained, humidity-friendly space without spending over $100.
Expert Verdict: North Spore BoomRoom II Automated Martha Tent Kit
North Spore BoomRoom II Automated Martha Tent Kit
The BoomRoom II solves a real problem: the Martha tent setup has always been a tangle of zip-tied humidifiers, makeshift fans, and guesswork humidity levels. At $479, you're paying for integrated automation that genuinely replaces hours of weekly maintenance and the trial-and-error of DIY builds. The missing warranty and parts availability information is a legitimate concern before committing, but for serious hobbyists producing multiple species at volume, the five-rack capacity and hands-off humidity control justify the price.
Buying Guide
How to choose the best martha tent mushroom setup
Finding the best martha tent mushroom setups means sorting through a lot of gear with overlapping specs and inconsistent quality. This guide cuts straight to the five decisions that actually determine whether your fruiting chamber holds humidity, maintains airflow, and produces consistent flushes. Work through each step in order before spending a dollar.
-
1
Set Your Growing Scale
Decide upfront how many fruiting blocks or bags you plan to run simultaneously, because tent size drives every other purchase. A 4×4 tent handles 9 to 12 standard 5-pound blocks, while a 2×4 fits 4 to 6 blocks comfortably without crowding airflow. Overcrowding tanks humidity consistency and invites contamination, so build for 20 percent more space than you think you need.
-
2
Choose Your Humidifier Type
Ultrasonic humidifiers like the Levoit Classic 300S push cold mist that raises relative humidity to 90 to 95 percent quickly without raising tent temperature, which matters for species like lion's mane and oysters. Warm mist units add heat that can stress fruiting bodies and promote bacterial growth on substrate surfaces. Match humidifier tank size to your tent volume, targeting at least 1 liter of capacity per 8 cubic feet of tent space.
-
3
Plan Your FAE System
Fresh air exchange, or FAE, is where most beginner martha tent setups fail because growers underestimate how much CO2 fruiting mushrooms exhale. Install an inline fan rated for your tent's cubic footage, typically a 4-inch AC Infinity Cloudline for tents up to 4x4x6.5 feet, paired with a speed controller to dial airflow without drying surfaces. Run your fan on a timer set to 1 to 2 minute bursts every 15 to 30 minutes rather than continuous flow, which strips humidity faster than your humidifier can replace it.
-
4
Select A Controller Unit
An environmental controller like the Inkbird IHC-200 or AC Infinity CONTROLLER 67 lets you automate humidity triggers so your humidifier activates only when RH drops below your target threshold, typically 85 to 90 percent for most gourmet species. Without a controller you are manually adjusting equipment multiple times per day, which introduces inconsistency that shows up as cracked caps and aborted pins. Confirm the controller supports both a humidifier and fan outlet simultaneously before purchasing.
-
5
Verify Shelf And Drainage Setup
NSF-certified wire shelving in 18×48 inch sections fits cleanly inside a 4×4 tent and allows humidity to circulate around blocks from all sides rather than pooling underneath. Line the tent floor with a waterproof tray or cut a section of pond liner to catch condensation and runoff from misting, since standing water breeds contaminants within 48 hours. Confirm shelf weight ratings exceed your fully hydrated block load by at least 50 percent, as 10 saturated 5-pound blocks plus hardware approaches 70 pounds on a single tier.
How We Tested
We ran each of the five martha tent mushroom setups through a 6-week oyster mushroom fruiting cycle, measuring temperature stability, humidity retention, and contamination rates across identical substrate blocks in a controlled 68F basement environment.
- Humidity hold time between misting cycles
- Shelf spacing and block access ergonomics
- Tent zipper seal and light leak integrity
- LED spectrum output and timer accuracy
- Assembly time and hardware fit quality
Frequently Asked Questions
Martha tents win for lion's mane and other high-humidity species because they hold 85 – 95% RH consistently across a large vertical space, allowing multiple shelves of blocks to fruit simultaneously. Shotgun fruiting chambers work fine for oysters but struggle to maintain the stable, even humidity that lion's mane needs without constant manual misting. If you plan to grow more than one species or scale beyond a few blocks, the martha tent's ultrasonic humidifier integration makes it the more practical long-term choice.
Pre-built kits typically run $150 – $300 compared to $60 – $100 for a DIY build using a chrome wire shelf and clear poly sheeting, and the price premium buys you better zipper access panels, reinforced duct ports, and a frame designed to hold weight without bowing. If you're growing fewer than 10 blocks at a time, the DIY route performs nearly as well for a fraction of the cost. The kit makes more sense if you're automating with an Inkbird controller and inline fan, since the dedicated ports simplify installation significantly.
A 4-tier setup fits standard 5-pound grain or fruiting blocks with 12 – 14 inches of clearance per shelf, which is sufficient for oysters and shiitake but tight for species that pin high. A 6-tier configuration maximizes vertical space in a 72-inch tent but reduces per-shelf clearance to around 9 – 10 inches, making it a poor choice for blocks that need overhead room for large mushroom clusters. Measure your average block height plus expected pin height before committing, and factor in whether your humidifier sits inside the tent, since that consumes one full shelf position.
Most standard bedroom humidifiers output 200 – 300 mL per hour, which is insufficient to maintain 90% RH in a 4x2x6-foot tent once you account for air exchange from an inline fan. You need at least 500 mL/hour output, and for tents larger than 48 cubic feet, a 1 – 2 liter/hour unit paired with a humidity controller like the Inkbird IHC-200 is the minimum viable setup. Undersizing the humidifier is the single most common reason growers report inconsistent pinning and low yields despite otherwise correct technique.
Standard 10-pound fruiting blocks measure roughly 8x8x10 inches when fully colonized, so you need at minimum 14 inches of vertical clearance per shelf to accommodate pinning without crowding. Most martha tents are built around 48×24-inch wire shelving units, which fit in closets at least 26 inches deep and 50 inches wide – measure your doorframe width before ordering, since 24-inch-deep units ship assembled and may not clear a 24-inch interior door. Tents in the 36-inch-wide format exist for tighter spaces but sacrifice one full column of shelf capacity.
The wire shelf frame and poly tent fabric realistically last 3 – 5 years under daily use, but zipper corrosion and fabric seam separation from constant 90%+ humidity exposure are the most common failure points, usually appearing at the 18 – 24 month mark. Ultrasonic humidifier transducers degrade faster in humid environments and typically need replacement every 12 – 18 months depending on water mineral content, with distilled water extending transducer life noticeably. Most martha tent kits are sold without warranties longer than 90 days, so budget for zipper replacement hardware and a backup humidifier transducer from the start.
