What equipment do I need to get started?

Basic equipment includes: pressure cooker, sterile containers, substrate materials, inoculation tools, and a clean workspace. Refer to the supplies sections in each instruction phase for detailed lists.

How long does the entire growing process take?

The complete growing process typically takes 29-48 days from inoculation to harvest.

What is the difference between agar and liquid culture?

Agar culture involves growing mycelium on a nutrient gel in petri dishes, allowing visual inspection and isolation of clean cultures. Liquid culture grows mycelium suspended in a nutrient solution, providing faster colonization for inoculating grain spawn.

How do I know if my culture is contaminated?

Signs of contamination include: green, black, or pink discoloration; foul odors; irregular growth patterns; and bacterial wetness. Healthy mycelium appears white and fluffy with consistent growth.

What substrate should I use?

For this species, Wood, grain is recommended.

Why are my mushrooms not pinning?

Common reasons include: insufficient fresh air exchange, incorrect temperature or humidity levels, inadequate light, or the substrate needs more time to fully colonize. Review the primordia formation parameters.

What temperature range is optimal?

For fruiting, maintain 55-65°F.

How much fresh air exchange is needed?

This species requires 2-4 air exchanges per hour during fruiting.

When should I harvest?

Harvest timing depends on the species. Generally, harvest when caps begin to flatten out but before spore release. Check for firm texture and optimal size according to species characteristics.

How many flushes can I expect?

This species typically produces 1-2 flushes.

Shimeji guide actually worked

01/30/2025

First time growing and my batch came out faster than expected. Store bought shimeji doesnt even compare taste-wise. The humidity tips were clutch - wouldve messed that up otherwise

Shimeji came out great

Easy to follow even for a beginner. Tips on humidity and temp really helped. Harvested my own shimeji in a few weeks. Added great umami to stir fries

Good shimeji guide

Wanted to try growing shimeji at home and this helped a lot. They need cooler temps than I expected. Got some small clusters forming now so fingers crossed.
