If you are weighing a monotub for mushroom vs Vivosun setup for your home grow, you are really choosing between a compact, self contained tub and a larger tent style fruiting space. The Grower’s Select 28Q Cube Mushroom Monotub Fruiting is a 28 quart cube kit sold as a 2-pack for small batch growing, while a Vivosun style setup is typically a greenhouse tent with shelving that can hold many tubs or blocks at once. One favors control and simplicity in tight spaces, the other favors volume and expansion.
The real decision comes down to batch size, available floor space, and how hands on you want to be with misting and airflow in November 2026. If you want to fruit one or two small bulk mixes with minimal gear, a cube monotub keeps everything contained. If you want to run overlapping flushes or multiple species, a tent gives you shelves to scale. Our breakdown in the Monotubs, Martha Tents & Fruiting Chambers guide follows the same logic around matching chamber size to your routine.

Pros
- Durable high density polypropylene tubs built for repeated use
- Includes filters, liners and plugs for a ready to use chamber setup
- Compact cube footprint saves space while still offering solid growing volume
- Stackable design helps growers scale up without needing more floor space
- Simple airflow management for both incubation and fruiting phases
Cons
- 28-quart size is limiting if you want large harvests or bigger flushes
- Requires separate purchase of grain spawn and bulk substrate to get started
- Cube shape offers less surface area than longer monotubs, which may reduce yield per tub
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.

How They Compare
Footprint and Growing Volume
The Grower’s Select 28Q Cube Mushroom Monotub Fruiting measures 12″ x 12″ x 12″ OD, so each tub has a square, compact footprint that fits on a closet shelf, desk, or stacked in a corner. It is rated for 32 to 48oz of grain spawn with 4 to 5lbs of bulk substrate per tub, which points to modest, manageable flushes rather than bulk harvests. A Vivosun style tent, by contrast, is a full height shelving unit with a cover, so growers commonly report using it to hold multiple tubs, trays, or fruiting blocks across several shelves at once.
For apartment growers, that size difference matters every day. The Grower’s Select 28Q Cube Mushroom Monotub Fruiting lets you start one tub while the second tub colonizes, without dedicating a whole corner to a greenhouse. A Vivosun tent needs open floor space plus clearance for the door zipper and airflow, but it rewards you with room to stagger grows. If you only have a shelf, choose the cube, if you have a spare closet corner and want continuous harvests, the tent style makes more sense.
Air Exchange, Humidity and Incubation Control
The Grower’s Select 28Q Cube Mushroom Monotub Fruiting uses 4 air holes fitted with 2.5 inch Monotub Filter Disks to allow passive fresh air exchange while limiting contaminants. The kit includes 8 Monotub Filter Disks and 8 plugs, so you can close the holes during incubation to hold warmth and moisture, then swap to filters for fruiting. A Vivosun style tent relies on a much larger air volume, with passive vents, a cracked door, or a small fan for exchange, and growers commonly report adding a humidifier and hygrometer to keep humidity steady across all shelves.
In practice, the Grower’s Select 28Q Cube Mushroom Monotub Fruiting is simpler to dial in because you are managing humidity in only 28 quarts, with manual misting and fanning or passive filters doing most of the work. A Vivosun tent can dry unevenly, with lower shelves staying damp while top shelves dry from fan flow, so you will check multiple spots and adjust venting often. If you enjoy a simple routine of checking surface moisture and adjusting plugs or disks, you will like the cube, if you prefer to set up a humidifier on a timer, the tent rewards that extra gear.
Build Quality, Stackability and Cleanup
The Grower’s Select 28Q Cube Mushroom Monotub Fruiting is made from high density polypropylene described for durability and resilience, with a stackable base that can support up to 10 bins stacked above and up to 150 lbs per monotub. That stacking strength is useful when you want to colonize one tub while fruiting another, or store empty tubs vertically between runs. A Vivosun style tent uses metal poles with connectors and a flexible cover, which is sturdy for holding lightweight tubs and blocks but depends on even assembly and careful zipper use to stay sealed and upright.
Cleanup also feels different between the two styles. The Grower’s Select 28Q Cube Mushroom Monotub Fruiting has smooth interior walls and a square shape that wipes down quickly, and the included liners help reduce side pins and make spent substrate removal cleaner. A Vivosun tent has more surface area to maintain, including shelves, poles, drip trays, and the inner cover where moisture can collect, so growers commonly report wiping shelves and airing the cover between cycles. If you want fast turnaround with minimal scrubbing, the cube wins, if you do not mind a longer reset for more capacity, the tent is workable.
Kit Completeness and Beginner Friendliness
The Grower’s Select 28Q Cube Mushroom Monotub Fruiting ships as a 2-pack with 8 Monotub Filter Disks, 2 liners, and 8 plugs included, so you can set up two full chambers without sourcing separate filters or liners. With a 4.6 out of 5 rating from 314 reviews, many buyers point to the ready to assemble nature and clear incubation to fruiting transition using plugs then filters. A Vivosun style tent is usually sold as the tent and shelves alone, which means you still need tubs or blocks, plus humidity control, airflow, lighting, and shelving trays to create a complete fruiting environment.
For beginners, that completeness gap is important. The Grower’s Select 28Q Cube Mushroom Monotub Fruiting lets you focus on spawn ratio, substrate moisture, and surface conditions rather than building a climate system. A Vivosun setup asks you to balance humidifier output, vent opening, and shelf placement all at once, which can be rewarding but has more variables to learn. Readers comparing tent options in our martha tent kit vs martha tent for mushroom article will see the same pattern, where kits with included controls are easier to start than bare tents.
Which One Should You Get
Choose Grower’s Select 28Q Cube Mushroom Monotub Fruiting if you grow in a small apartment, closet, or spare shelf and want contained, low fuss fruiting chambers for personal batches. It fits your routine when you plan to use 32 to 48oz of grain spawn with 4 to 5lbs of bulk substrate per tub, stack tubs to save space, and manage incubation with plugs before switching to 2.5 inch filter disks for fruiting. You will also appreciate the included liners for cleaner harvests and the durable polypropylene build that supports stacking, plus the simplicity of misting one small chamber instead of balancing a whole tent.
Choose Vivosun if you want to fruit multiple tubs, trays, or blocks at the same time and you have floor space for a shelving greenhouse with room to open the door and service shelves. It fits your goals when you plan to stagger inoculation dates, run different species side by side, or add automation like a humidifier, fan, and timer for steadier conditions. You should be comfortable monitoring temperature and humidity at more than one shelf level and cleaning poles, trays, and covers between cycles, as covered in our how to use martha tent for mushroom growing at home walkthrough for tent style growing.
Who Should Skip Both
You should skip both styles if your grow plans do not match contained bulk tubs or tent shelving, and this setup is not ideal for growers who only want to fruit small all in one bags without any chamber care. It is also not a good fit if you need a fully automated, set and forget fruiting room with active climate control, since both options still require daily checks for moisture, airflow, and harvest timing. If you dislike manual misting, wiping surfaces, and monitoring surface conditions, consider starting with a simpler countertop kit first, or read our monotub liner vs martha tent kit comparison to clarify how much hands on care each chamber style expects.
Frequently Asked Questions
Is a monotub for mushroom vs Vivosun tent better for beginners with limited space?
For limited space, a monotub is usually easier because the Grower’s Select 28Q Cube Mushroom Monotub Fruiting occupies only a 12″ x 12″ footprint and includes filters, plugs, and liners for two tubs. A Vivosun tent needs dedicated floor space and extra gear for humidity and airflow. Start with tubs if you have only a shelf, move to a tent when you need shelves.
How much spawn and substrate fits in Grower’s Select 28Q Cube vs a Vivosun tent?
Each Grower’s Select 28Q Cube Mushroom Monotub Fruiting is designed for 32 to 48oz of grain spawn with 4 to 5lbs of bulk substrate, which suits small to medium flushes. A Vivosun tent does not have a single fill ratio because growers commonly report placing several tubs or blocks on its shelves. Use the cube ratio for consistent tubs, use the tent when you want to run multiple batches in parallel.
Can I use monotub filter disks and plugs inside a Vivosun tent?
Yes, many growers place filtered monotubs inside a tent to get both micro and macro climate benefits, using plugs during colonization and 2.5 inch disks during fruiting. The tent then acts as a humid room around the tubs rather than the primary chamber. Just keep tent humidity moderate and still allow tub level exchange so surfaces do not stay overly wet.
