Mushroom Monotub Kit

Complete Monotub Mushroom Grow Kit

Everything you need for large-scale mushroom cultivation—sterilized grain spawn bags, nutrient-rich CVG substrate, and a professional-grade monotub system. No need to buy supplies separately; we’ve bundled it all into one beginner-friendly, professional-quality grow kit.

Whether you’re just starting your first grow or scaling up for serious yields, this monotub kit is built to make growing mushrooms simple, reliable, and actually fun.

Professional Grain Spawn Process

We don’t cut corners in our sterilization process:

1. 24-hour soak with gypsum for balanced pH and hydration

2. 15-minute simmer to prep grains
   

3. 60-minute dry for perfect moisture content

4. Filled into Unicorn .2 micron filter bags
   

5. Sterilized at 17 psi for 90 minutes

6. Sealed behind HEPA flow hood
   

Clean, strong grain = faster colonization + bigger yields.

How it Works: Easy Mushroom Growing Process

1. Inoculate → Inject 2-5 cc spores/LC into each grain bag.
   

2. Colonize → Wait ~3 weeks until fully colonized.
   

3. Spawn to Bulk → Mix colonized grain with CVG substrate in the monotub.
   

4. Fruiting → After colonization, open air exchange and maintain humidity.

5. Harvest → Twist & pull mushrooms once mature; repeat for multiple flushes.

Frequently Asked Questions

What mushrooms can I grow with this monotub kit?

Our kit is designed for dung- and straw-loving mushrooms, including many gourmet and medicinal varieties. Just add your spores or liquid culture.

Do spores come with the kit?

No. Spores or liquid culture are not included. You’ll need to source them separately. The kit includes sterilized grain spawn, bulk substrate, and a monotub with filters.

Is this a beginner-friendly mushroom grow kit?

Yes. Our complete monotub kit is designed for first-time growers as well as experienced cultivators. Everything is pre-sterilized and ready to use, so there’s no need for pressure cookers or complicated lab equipment.

Can I fruit mushrooms directly in the monotub kit?

Yes. This monotub mushroom grow kit is designed for direct fruiting once colonization is complete.

How much yield can I expect from a mushroom monotub kit?

Most growers average 6+ ounces of dry mushrooms across multiple flushes, depending on genetics and culture cleanliness.

Do I need a flow hood or pressure cooker?

No. All grain bags and substrate bags are already sterilized and sealed. Just inoculate and grow.

What’s the difference between a monotub kit and an all-in-one grow bag?

All-in-one mushroom grow bags are compact, while a monotub mushroom kit allows for larger yields and multiple flushes. Monotubs are ideal for growers looking to scale up.

Do I need to drill or modify the tub?

No. The monotub comes with pre-installed filter patches and a gasket lid—no drilling required.

Can I grow mushrooms indoors with this kit?

Absolutely. This monotub kit is designed for indoor mushroom cultivation, giving you a reliable setup that can produce consistent results in small spaces.

Do you sell monotubs separately?

No, we don’t sell monotubs on their own. Each mushroom monotub kit is designed as a complete system—grain spawn, substrate, and tub work together to maximize colonization and yield.
