If you are weighing Vivosun vs monotub for mushroom growing, you are really deciding between two different fruiting styles. On one side is Grower’s Select 28Q Cube Mushroom Monotub Fruiting, a compact passive chamber. On the other side is VIVOSUN AeroStream H05 1.32 Gal Smart WiFi, an active humidifier built to support a tent or small room.
You want a clear verdict based on your space, your daily routine, and how much control you prefer. Updated November 2026, we assessed specs and grower feedback for both options to map each one to a specific grow. If you browse our Monotubs, Martha Tents & Fruiting Chambers hub, you will see why this passive versus active choice matters so much for steady pinning.

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.
Brand: MycoLabs, Model: Grower's Select 28Q Cube Monotub, Quantity: 2 Pack. Material: High density polypropylene in black with rectangular cube shape.
Capacity: 28 quarts per tub. Dimensions: 12L x 12W x 12H inches. Weight: 4.3 pounds. Special feature: Stackable design.
In the box: 2 monotub chambers, 8 filter disks, 2 liners and 8 plugs. Recommended fill: 32 to 48 oz grain spawn with 4 to 5 lbs bulk substrate per tub.
Pros
- Highly accurate external temperature and humidity probe for reliable readings
- Three control modes plus custom grow recipes through the app
- Quiet ultrasonic mist with adjustable output and constant humidity mode
- Easy top fill design with low water alert and simple cleaning process
Cons
- Full smart features require WiFi and the Vivosun app setup
- Compact 5L capacity needs frequent refills at high mist output
- Best suited for small to medium spaces, not whole house humidification
The VIVOSUN AeroStream H05 is a 5-liter smart ultrasonic humidifier built specifically for indoor growers, tent setups and small rooms. It is ideal for anyone growing plants, managing a terrarium, or needing stable humidity in spaces from 50 to 150 square feet.
Its standout feature is precision control with 1% humidity resolution and a sensitive external probe for real time readings. Connected to the Vivosun app, it auto adjusts mist output to hold your target humidity and VPD in Auto, Manual or Cycle modes.
Design is grower focused with a black opaque tank that resists buildup, a top fill opening for easy refills, and a flexible hose with vapor outlet for inside or outside tent use. Phantom mode turns the screen off completely, so no stray light affects plants, while operation stays whisper quiet.
The main tradeoffs are reliance on WiFi and the app to unlock full smart control, plus more frequent refills when running at max output. Coverage is also limited to small and medium spaces, so it is not meant for large open areas.
Overall, the AeroStream H05 is a smart choice for growers who want automated, accurate humidity without constant monitoring. If you already use the Vivosun Smart Grow System, the integration and recipe control make it even more valuable.
Model: VSE-ASH05, Capacity: 5 liters, Dimensions: 7.4 x 13.9 x 7.4 inches, Weight: 2.5 kg
Coverage: 50 to 150 sq ft, Operation Mode: Ultrasonic, Power: 30 watts, Special Feature: Quiet operation

How They Compare
System Type and Footprint
Grower’s Select 28Q Cube Mushroom Monotub Fruiting is a self contained fruiting chamber with 28 Quart volume and outside dimensions of 12″ x 12″ x 12″. You add grain spawn and bulk substrate directly inside, close the lid, and manage air through the side holes. VIVOSUN AeroStream H05 1.32 Gal Smart WiFi is not a chamber at all, it is an ultrasonic humidifier with a vapor outlet and flexible hose that feeds moisture into your existing tent, terrarium, or room covering 50 to 150 sq. ft.
For small apartments, closets, or stacked grows, the monotub has a clear footprint advantage. The base is designed to stack up to 10 bins high and each monotub can support up to 150 lbs stacked on top, so two tubs can live on a shelf without extra gear. The VIVOSUN unit needs a tent or enclosed space plus power and WiFi to shine, but it can serve a much larger canopy than a pair of 12 inch cubes when you already have that enclosure.
Humidity and Air Exchange Control
Humidity control is where Vivosun vs monotub for mushroom growers splits most sharply. Grower’s Select 28Q Cube Mushroom Monotub Fruiting uses 4 air holes fitted with 2.5 inch Monotub Filter Disks to allow passive exchange while limiting contaminants. You get 8 Monotub Filter Disks and 8 Plugs in the 2 Pack, so you can block holes during incubation and then open them for fruiting to raise exchange without fans or sensors.
VIVOSUN AeroStream H05 1.32 Gal Smart WiFi takes an active approach with 1% humidity resolution, an external temperature and humidity probe, and Auto, Manual, or Cycle modes. You set a target in the Vivosun app and it adjusts mist output to hold steady moisture, with real time humidity and VPD data and Phantom mode to disable the screen. That precision helps in dry rooms or Martha tents, though you still need to provide fresh air separately because mist alone does not replace exchange.
Setup, Operation and Daily Routine
Setup for Grower’s Select 28Q Cube Mushroom Monotub Fruiting is simple and manual. You line the high density polypropylene tub with one of the 2 included liners, add 32 to 48oz of grain spawn with 4 to 5lbs of bulk substrate per tub, and use the plugs to hold humidity during colonization. If you want context on other enclosed options, our guide to fruiting chamber kit vs martha tent shows how this tub style compares to larger tent systems for daily care.
Setup for VIVOSUN AeroStream H05 1.32 Gal Smart WiFi involves filling the 1.32 Gal tank from the top opening, placing the unit inside or outside the tent with the hose routed in, and connecting to WiFi for remote control and low water alerts. Daily use is more automated once your recipe is saved, and cleaning is guided by step by step video instructions. The trade off is maintenance, you must refill, wipe the tank, and keep the hose and probe positioned correctly, while the monotub routine centers on visual checks and occasional manual misting or fanning.
Build Quality, Capacity and Grower Feedback
Build quality reflects two different jobs. Grower’s Select 28Q Cube Mushroom Monotub Fruiting uses high density polypropylene for resilience through repeated grows, and growers commonly report that the cube shape holds surface conditions well for its size. It is rated 4.6 out of 5 from 314 reviews, which signals consistent satisfaction for small batch growers. The limit is capacity, each tub is sized around 1.0 to 1.5lbs of spawn plus bulk substrate, so you are running discrete small flushes rather than a continuous tent harvest.
VIVOSUN AeroStream H05 1.32 Gal Smart WiFi uses an opaque water tank to reduce buildup inside, plus adjustable mist output and intelligent constant humidity settings for cleaner vapor. It is rated 4.2 out of 5 from 1213 reviews, a solid score across a much larger buyer base that includes plant tents, bedrooms, and living rooms, not only mushroom growers. For mushrooms, that means you should read mushroom specific feedback closely, and see our mushroom grow tent for oyster mushroom picks to understand what size tent pairs well with a 50 to 150 sq. ft humidifier.
Which One Should You Get
Choose Grower’s Select 28Q Cube Mushroom Monotub Fruiting if you want a low cost, low tech start with minimal equipment and a small footprint. You are a good match if you grow one or two tubs at a time in a closet or spare room, prefer to learn surface conditions by eye, and like that liners, filter disks, and plugs are included in the 2 Pack. It also suits growers who want stackable storage and a simple incubation to fruiting transition by swapping plugs for filters.
Choose VIVOSUN AeroStream H05 1.32 Gal Smart WiFi if you already run a Martha tent or small grow tent and struggle to hold humidity through dry days or heater cycles. You are a good match if you value remote monitoring, scheduled recipes, VPD tracking, and alerts over manual misting, and you are comfortable cleaning a humidifier on schedule. For budget tent planning, check How to Use a Mushroom Grow Tent on a Budget before you buy, since the humidifier works best when your enclosure is reasonably sealed and vented.
Who Should Skip Both
You should skip both if you need a large automated Martha system with shelving, lighting, and exhaust in one kit, since neither product provides that complete setup alone. This pair is not ideal for growers who want zero maintenance, because the monotub still needs observation and manual adjustments while the humidifier needs refills, cleaning, and a suitable tent to be effective. If you dislike any daily checks or do not have space for even a 12 inch cube plus a water reservoir nearby, consider a different fruiting approach first.
Frequently Asked Questions
Can a Vivosun humidifier replace a monotub for mushroom fruiting?
No, it does not replace the chamber itself. VIVOSUN AeroStream H05 1.32 Gal Smart WiFi adds controlled moisture to a tent or room, while Grower’s Select 28Q Cube Mushroom Monotub Fruiting provides the enclosed tub where colonization and fruiting happen. Many growers use a similar humidifier to support a tent that holds tubs or trays.
How much spawn and substrate fits the 28Q monotub?
Each Grower’s Select 28Q Cube Mushroom Monotub Fruiting tub is sized for 32 to 48oz of grain spawn with 4 to 5lbs of bulk substrate. That ratio helps maintain moisture and surface conditions in the 12″ x 12″ x 12″ space. The 2 Pack includes 2 liners, 8 filter disks, and 8 plugs to run both tubs.
Is the Vivosun smart humidifier good for a small mushroom tent?
Yes for humidity stability in tents and rooms from 50 to 150 sq. ft, especially when indoor air runs dry. You get an external probe, 1% humidity resolution, app control, and hose placement inside or outside the tent. You will still need fresh air exchange and routine cleaning for reliable mushroom results.
