Best monotub kits and bulk fruiting tubs for home mushroom growing

What the listing offers

• Includes everything except the culture: tub, two injection-port grain bags, 10 lb of bulk substrate and casing
• Listing states the spawn to bulk ratio and the resulting 3 inch layer, so first-timers do not have to guess quantities
• Tub measures 22.5 x 15.5 x 12 inches and comes with six 2.5 inch filter disks and hole plugs for incubation

Limits to know

• Bulk substrate is manure based, which suits compost and dung-loving species, not oysters or lion's mane
• At about 66 quarts it needs a shelf or floor space, too big for a countertop

What the listing offers

• Kit contents are listed in full: tub, 10 lb of sterile substrate, 3 lb grain bag, casing and 1 and 2 inch filters
• States the recommended rate of 1 lb grain spawn per 5 lb substrate
• Tub holds up to 25 lb of substrate and has a light-blocking base against side pins

Limits to know

• Highest priced of the non-automated kits here
• Manure-based substrate limits it to compost and dung-loving species

What the listing offers

• Fan, mister and humidity controller are matched to the tub, so no drilling or fitting parts from different brands
• Recessed base lets several tubs stack, and lid latches stop the lid lifting when the tub is moved
• Holds up to 25 lb of substrate, enough for a full bulk grow

Limits to know

• Most expensive pick and still needs grain spawn and bulk substrate bought separately
• Needs a power outlet near the tub for the fan, mister and controller

What the listing offers

• CVG substrate is low in nutrients, which the listing presents as more forgiving of contamination for beginners
• Boomr Bin design accepts later upgrades such as a fresh air fan and humidity controller
• Comes from an established mushroom supply brand with filters included

Limits to know

• Listing does not state the grain spawn weight in the feature bullets shown, so check the product page
• CVG is aimed at dung-loving species, wood-loving gourmet mushrooms need a hardwood substrate instead

What the listing offers

• Row of 1 inch lid holes is meant to give even fresh air exchange and prevent long, fuzzy stems
• Black base blocks light from the sides, which helps stop side pinning
• Food-grade tub rated for up to 25 lb of substrate

Limits to know

• Empty tub only: no substrate, grain spawn or casing layer included
• Filter sheets are consumables, so plan on replacements after a few grows

What the listing offers

• 48 quart size, 18 x 15.5 x 12 inches, sits between small cube tubs and large 66 quart bins
• Six filtered air holes plus plugs to close them during colonization
• Stackable base, the listing states it supports bins stacked ten high

Limits to know

• Empty tub only, with no grain spawn or bulk substrate in the box
• Lower brand profile than North Spore, the listing gives few details about the liner

What the listing offers

• Two small tubs let you split spawn and keep one going if the other contaminates
• Listing gives exact spawn and bulk quantities per tub
• Compact 12 inch cube fits on a kitchen shelf or in a closet

Limits to know

• Each tub has four air holes, fewer than the larger tubs, so fresh air exchange is lower
• Small surface area per tub means smaller flushes than one large bin

What the listing offers

• Collapses flat for storage between grows, useful in apartments
• Drain port makes it easier to remove water after soaking or misting
• Clear walls let you check pins without opening the lid

Limits to know

• Inflatable walls are less rigid than a molded tub and can be punctured
• Clear sides let light in, so pins may form along the walls unless the liner covers them
