3 lb All-In-One Mushroom Grow Bag | Sterilized Grain + Substrate

Sterilized Grain + Nutrient-Balanced Substrate in One Bag
Inject • Mix • Fruit • Harvest

Everything you need in one sterile, ready-to-inoculate bag.

Small-Batch Production. Quality Focused.
Each All-In-One Bag is produced in limited runs and allowed proper rest time before release. We make them in small batches to ensure consistency, sterility, and quality.
⚠️ Because of this small-batch process, these bags frequently sell out between production runs.
If they are available now, we recommend ordering while they are in stock.
Current Production Run: Available
Once this batch sells out, new bags will be produced and rested before the next release.

Simple 4-Step Process


1) Inoculate

Inject 1–3cc of liquid culture through the injection port into the grain layer only. For best results, 2–3cc is typically ideal for a 5lb bag.


2) Break & Mix

When grains are 50–70% colonized, mix thoroughly into the substrate.


3) Fruit

Once fully colonized, allow the bag to expand and introduce indirect light.


4) Harvest

Open the bag and harvest when mature. Additional flushes may be possible with proper care.
