⭐ Liquid culture or spores required (LC preferred). We do not sell liquid culture, spores, or cultures of any kind.

1) Inoculate

Inject 2–10cc of liquid culture through the injection port into the grain layer only. For best results, 2–5cc 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.

How much culture should I use?
2–10cc is recommended. For most cultures, 2–5cc is typically ideal for a 5lb bag.

Where do I inject?
Inject through the injection port into the grain layer only — not directly into the substrate.

When should I mix the bag?
Mix when the grain reaches approximately 50–70% colonization.

How long does the process take?

• Grain colonization: ~10–20 days
• After mixing to full colonization: ~10–14 days
• Pinning after fruiting conditions: ~5–10 days
• Timeframes are estimates and vary by genetics, temperature, and environment
