All-In-One Mushroom Growing Bags – 2 Packs, 10 lbs, Ready to Grow

Grow more with our 2-Pack All-In-One Mushroom Grow Bags. Each jumbo 5 lb bag comes pre-sterilized, hydrated, and ready to use. That’s 10 lbs of growing potential—twice the chances of success without overcommitting. The perfect middle ground between a single bag and a bulk bundle. 

No tubs, no messy mixing, and no extra equipment required. Just inject your spores or culture, wait, and enjoy bigger harvests for less. (Unless you want extra supplies...since we’ve got those too.)

Grow Mushrooms in 4 Easy Steps

1. Inoculate: Inject spores or LC into the bag (2–3 cc).
   

2. Mix: Once colonized, break up grain and mix with substrate.
   

3. Fruit: Bag inflates as mushrooms form.
   

4. Harvest: Open, twist & pull at base.

Each mushroom grow bag yields 3+ oz of dried mushrooms, depending on genetics and cleanliness of your culture.

Frequently Asked Questions

Why get the 2 pack instead of a single bag?

The 2 pack gives you more flexibility and higher success rates. If one bag contaminates, the second ensures you still get a harvest.

How much will the 2 pack yield?

Each bag yields 3+ oz dried mushrooms. With two bags, you can expect 6+ oz or more, depending on genetics and technique.

Can I run both bags at the same time?

Yes, or you can stagger them to spread out your harvest window.

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

A substrate bag only contains the fruiting substrate. Our all-in-one mushroom grow bag kit combines both sterilized grain and substrate in one bag—making it easier and faster to grow.

Do I need to refrigerate or store the bags in a special way before inoculating?

Bags are shelf-stable. Store them in a cool, dark place (under 72°F) until you’re ready to inoculate.

What makes your grow bags for mushrooms different?

We use thicker Unicorn-brand bags, proper long-soak prep with gypsum, sterilization at 17 PSI for 2+ hours, and HEPA-sealed packaging. No shortcuts, no cheap imports, and no under-filled substrate.
