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 54-100 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, Logs or sawdust 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 50-70°F.

How much fresh air exchange is needed?

This species requires 4-8 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 3-4 flushes.

Shiitake blocks need months to brown before they'll fruit — skip that step and you'll get nothing. This guide walks through the full cycle from sawdust to harvest, including the soak-and-shock technique that triggers flush after flush.

Thorough and easy to follow even for beginners. Visuals helped me understand what each stage should look like. Shiitakes started popping up after a few weeks. Flavor is amazing

Good info on growing shiitakes on logs vs blocks. I went with blocks since I dont have outdoor space. Takes forever for them to fruit but the guide prepared me for that at least.
