The MycoLabs Grower's Select 28Q Cube is a 2-pack of compact mushroom fruiting chambers aimed at home hobbyists and beginners. Each 28-quart tub is sized for 32 to 48 ounces of grain spawn plus bulk substrate, making it ideal for manageable small batches.
In use, the four air holes with 2.5-inch filter disks promote steady fresh air exchange without constant fanning. The included plugs let you seal the tub for colonization, then switch to filters for fruiting, which helps maintain proper humidity and cleaner conditions.
Built from high density polypropylene, these tubs feel sturdy and reusable rather than flimsy storage bins. The 12-inch cube format is space efficient, and the stackable base supports vertical setups to maximize closet or shelf grows.
The main tradeoff is size, as the compact cube holds less substrate and offers less surface area than large monotubs. You will also need to supply your own spawn, substrate and misting routine, since this is a chamber kit rather than an all in one grow kit.
Overall, this 2-pack is a practical, well thought out option for growers who value durability, cleanliness and space savings. If you want a reliable starter or expansion chamber for steady personal grows, it is easy to recommend.
Brand: MycoLabs, Model: Grower's Select 28Q Cube Monotub, Quantity: 2 Pack. Material: High density polypropylene in black with rectangular cube shape.

It bundles the tub, humidification and ventilation into one ready to assemble kit. It is a strong fit for beginners, busy growers and anyone scaling up from manual tubs.
Standout features include the Myco-Mister Mini humidifier with hose, the FAE Fan Mini with power control and the Mycontroller humidity controller that acts as the brains of the setup. Together they maintain fresh air and moisture levels automatically for healthier pins and fuller flushes. In real world use, this means less misting, less fanning and more stable conditions through fruiting.
Build quality is practical and grow focused, with a compact yet sturdy tub that holds up to 25 pounds of substrate. The recessed base allows secure stacking of multiple units, which is ideal for small grow rooms or closets. Attached base latches keep the lid seated when lifting a loaded bin, while included filter sheets help manage airflow and cleanliness.
There are a few tradeoffs to consider before you commit to automation. The 22 x 15 x 11 inch footprint plus hoses and cords needs dedicated space near an outlet, and you will need to refill and clean the humidifier regularly.

Pros
- Large interior comfortably fits multiple trays, jars and culture tools
- Clear plastic offers excellent visibility for detailed sterile work
- Easy pop-up setup and collapsible fold-down storage
- Durable zippers and tear-resistant material hold up with repeated use

The Jaxbo Mushroom Still Air Box is a portable, collapsible mycology tent designed to create a clean, still air workspace for home growers and hobby scientists. With a large 35.5 inch footprint, it is built for inoculating grain, pouring agar, handling liquid culture and doing tissue culture work.
Its standout feature is the combination of dual side access zippers and built-in gloves that let you work without directly disturbing internal airflow. Users report it works well for gourmet mushroom inoculation, with clear visibility that makes it easy to see plates, jars and tools during delicate transfers.
The design uses clear plastic on five sides for full observation, set in a lightweight rectangular frame that pops up quickly. The material stays clear rather than blurry, zippers run smoothly, and long term users note it resists tearing with regular folding and storage.
It is not a rigid acrylic box, so walls can flex and the lightweight build can shift if bumped. Folding it back into its compact square shape takes practice at first, and the attached gloves offer less fine dexterity than working with bare hands inside a traditional tote style box.
Overall, this is a practical, space saving solution for beginners to intermediate mycologists who need sterile technique without a permanent lab setup. If you want a portable and easy to store still air workspace for mushroom cultivation, this Jaxbo tent is a smart pick.

Buying Guide for First Time Growers
We evaluated airflow design, moisture retention, capacity and cleanup across classic monotubs, inflatable models, all in one bags and compact tents. Our focus was low maintenance operation for new growers, not commercial output. Use the criteria below to match a chamber to your space, your workflow and how hands on you want to be.
You will see three main paths. A filtered monotub gives you a self contained bulk grow, an all in one bag skips the tub entirely, and a tent or still air box supports either scaling up or cleaner inoculation work. If you plan to expand later, our guide to Martha tent for home cultivation explains how tents complement tubs.
Filtration and Fresh Air Exchange Control
You want adjustable fresh air exchange without constant fanning. The Myco Labs Grower’s Select Mushroom 48Q Monotub uses six pre cut holes with 2.5 inch filter disks for steady gas exchange, plus plugs to close airflow during colonization. The Grower’s Select 28Q Cube Mushroom Monotub Fruiting follows the same idea with four filtered holes in a compact cube, which helps you avoid soggy or suffocated substrate.
For even more control, the Boomer Shroomer Inflatable Monotub Kit includes multiple plugs and one inch filters you can rearrange as pins form, while the North Spore ‘Boomr Bin’ Mushroom Cultivating combines lid level holes to reduce fuzzy stems with larger base filters for CO2 release. Start sealed with plugs, then swap to filters at fruiting for a smooth and forgiving transition.
- Look for 2.5 inch disks or dual size filters for balanced intake and exhaust
- Choose plugs for colonization control and easy humidity adjustments
- Prefer pre drilled holes over DIY drilling if you are new to monotubs
Humidity Stability and Simple Daily Care
You should not need to mist every few hours to keep pins happy. The Mushroom Growing Kit, Monotub Stackable Grow Box pairs six FAE ports with plugs and filters so you can dial humidity up or down, and its tight clear lid lets you check moisture without lifting and dumping humidity. A liner also helps hold moisture at the substrate level where it matters most.
If you want the most hands off start, the Mushroom Grow Kit – All-in-One 4LB Grow Bag creates its own humid micro climate with a 0.2 micron filter patch, so you skip tubs and humidifiers entirely. Larger growers may prefer the Mushroom Grow Tent with 6500K LED Light & Timer with its waterproof tray and hose ports for running a humidifier. Learn how bag grows differ from tub grows in our spawn bag workflow comparison.
- Pick a tight sealing clear lid so you can monitor without opening
- Use liners to reduce side pins and keep surface conditions even
- Consider a bag or tent with humidifier ports if your home air runs dry
Size, Capacity and Space Fit
Match volume to your spawn amount and your room. A 48 quart tub suits a full bulk mix and gives tall headroom for clusters, while the two pack 28 quart cubes let you run side by side small batches to learn faster from each flush. The square 12.6 inch stackable box is ideal for closets and shelves, and it stacks vertically when you want to double output without using more floor space.
When floor space is tight, the inflatable Boomer Shroomer collapses for storage and inflates to a full size fruiting area in minutes. The four tier grow tent holds multiple monotubs at once for vertical scaling, while the Large Still Air Box Mushroom Mycology Fume Hood and Mushroom Still Air Box 35.5×23.5×23.5 Inches give you a clean enclosed area for agar and inoculation work. See how vertical systems work in our Martha tent setup for Lion’s Mane walkthrough.
- Choose 28 quart cubes for small bulk grows and faster learning cycles
- Choose 48 quart or inflatable tubs for larger flushes and taller fruits
- Choose a tent only if you plan to run several tubs at once
Materials, Cleaning and Contamination Defense
Durable, easy to sanitize surfaces save you headaches between flushes. High density polypropylene tubs resist warping and support stacking, and included liners prevent side pins by blocking light on the sides and directing growth upward. The Boomer Shroomer adds a removable liner plus a drain port, so you can tilt out excess water after a soak without disturbing your substrate.
Clear walls and lids matter more than you think because every unnecessary opening drops humidity and invites contaminants. Look for food grade plastics, tight sealing lids and blackout bases like the Boomr Bin design. For cleaner transfers, pair any fruiting chamber with still air discipline and review our primer on using liquid culture for stronger and faster colonization.
- Prefer stackable, thick walled tubs that will not bow under substrate weight
- Pick removable liners and drain ports for quicker cleanup and rehydration
- Use a still air box for inoculation, then move colonized spawn to your fruiting tub
Final Thoughts
For a classic first bulk grow choose Myco Labs Grower’s Select Mushroom 48Q Monotub, while apartment growers wanting easy storage should pick Boomer Shroomer Inflatable Monotub Kit for a collapsible setup.
Frequently Asked Questions
What size mushroom fruiting chamber should a beginner start with?
Most new growers do well with a 28 to 48 quart monotub in 2026. That range fits standard spawn to substrate ratios, holds humidity well and still fits in a closet. Start small if you want to learn quickly, go larger once your colonization routine feels consistent.
Do I need to mist my monotub every day?
Not necessarily if your chamber seals well and uses filters plus plugs correctly. Many filtered tubs and all in one bags hold humidity for days with only occasional checks. Lift the lid only to confirm tiny water beads on the surface, then close it again to preserve moisture.
Should I choose a monotub or a grow tent for my first grow?
Choose a single monotub for your first grow because it is simpler, cheaper to run and easier to keep clean. A tent makes sense when you want to run several tubs, add a humidifier and control light on a timer. Compare layouts in our Martha tent kit comparison before you scale up in 2026.
How do I prevent side pins and fuzzy stems in my first tub?
Use a liner or blackout base to block side light, keep surface conditions even and avoid pooling water. Fuzzy stems often signal low fresh air exchange, so switch from plugs to filters at fruiting and keep lid holes open. The automated option like North Spore Automated ‘Boomr Bin’ Mushroom Monotub adds a fan and humidifier for steadier air and moisture if manual tweaks feel tricky.

This roundup is not the right choice if you are only running a single grow bag on a shelf; a dedicated fruiting chamber mainly pays off once you are running several tubs at once.
