More About These 5 lb & 10 lb Three Layered All-in-One Super Grow Bags
Heavyweight, high-performance grow bags built for big flushes and serious cultivators. These premium 5 lb and 10 lb all-in-one bags combine three sterilized layers into a single ready-to-inoculate unit—infused with added sulfates and nitrates for unmatched consistency, resilience, and explosive mycelial growth.
If you’re growing for real yield, this is the bag to reach for.
Choose Your Size
- 5 lb Bag – Ideal for mid-size cultivation setups, experimental runs, and small indoor spaces
- 10 lb Bag – Designed for bulk fruiting, high-output harvests, and mycologists scaling up production
Both sizes use the same materials, sterilization processes, and layer design—just in larger volumes than our standard grow kits.
What’s Inside the Bag?
Each bag contains three fully sterilized layers:
- Top Layer: Premium straw-based casing mix for surface moisture balance
- Middle Layer: Manure super mix, fully hydrated and pasteurized
- Bottom Layer: Infused organic rye berries treated with sulfates and nitrates during hydration for stability and accelerated growth
All layers are carefully packed and sealed to preserve sterile conditions and create an ideal microclimate for mushroom development.
Benefits of Infusion
We add sulfates and nitrates during the hydration phase of the grain to:
- Improve long-term stability during storage
- Enhance nutrient retention
- Support faster and more aggressive colonization
- Reduce the risk of premature spoilage or bacterial contamination
These additions are subtle, safe, and effective for increasing overall success rates—especially in higher-volume grows.
How to Use It
- Inoculate the bag directly with your selected spores or liquid culture
- Allow for full colonization in a dark, room-temperature area (2–4 weeks)
- Cut open and introduce fresh air/light for fruiting
- Harvest your first flush—then keep going
No monotub, bucket, or external substrate needed. The bag acts as its own mini ecosystem.
Who This Bag Is For
This high capacity grow bag is best suited for:
- Experienced cultivators scaling up their operation
- Bulk mushroom production (gourmet or legal species only)
- Educators demonstrating larger grows in classroom or lab settings
- Homesteaders growing for food security and wellness
Storage & Shelf Life
Store sealed bags in a cool location or refrigerate for best results. Do not freeze. For optimal viability, inoculate within 2–3 weeks of receiving your bag. All bags are prepared fresh to order.

This is by far the easiest method of growing shrooms

Absolutely blown away by the quality! I picked up a 5-pound bag of their manure super mix, and it was incredibly stable—my canopy size and flushes increased by what feel like tenfold! I also grabbed four of their 10-pound all-in-one super bags, and they were massive. I ran two with their active strains and the others with Lion’s Mane—every single one turned out amazing. On top of that, I’ve been working on my own genetics, so I stocked up on Fullsend agar. The small, compact cups make it super easy to work with, especially for someone at my skill level just starting out. Their customer service and quick response time has been top-notch, and I couldn’t be happier with my purchase. I’ll definitely be back for more!
