Agar Cultivation
- Prepare the agar medium by mixing agar powder with water according to the manufacturer's instructions.
- Autoclave the agar medium to sterilize it and let it cool to around 50°C.
- Pour the agar medium into sterile petri dishes, filling them about halfway full.
- Allow the agar to solidify in the petri dishes in a sterile environment, such as a laminar flow hood.
- Using a sterile technique, transfer a small piece of shiitake mushroom tissue onto the agar surface in each petri dish.
- Seal the petri dishes with parafilm or tape to prevent contamination.
- Incubate the petri dishes at the appropriate temperature for shiitake mushroom mycelium growth, typically around 25-28°C.
- Monitor the petri dishes for signs of mycelium growth, which may appear as white, cottony growth spreading from the tissue.
- Once the mycelium has fully colonized the agar medium, you can use it to inoculate your substrate for fruiting.
Liquid Culture Cultivation
- Prepare the liquid culture medium by mixing water, malt extract, and agar in a sterilized container.
- Autoclave the liquid culture medium to sterilize it and kill any contaminants.
- Allow the liquid culture medium to cool down to room temperature before proceeding.
- In a sterile environment, transfer a small piece of mycelium from a fully colonized agar plate into the liquid culture medium.
- Seal the container with a breathable lid or cover to allow for gas exchange.
- Incubate the liquid culture at the optimal temperature for shiitake mushroom mycelium growth, typically around 75-80°F (24-27°C).
- Monitor the liquid culture for signs of growth, such as cloudiness or mycelium strands forming in the medium.
- Once the liquid culture is fully colonized with mycelium, it is ready to be used for inoculating substrate for mushroom cultivation.
Spawn Instructions

Hey Josh, thanks for this awesome guide on growing shiitake mushrooms at home! I’ve always been curious about cultivating my own fungi, and your step-by-step instructions made it feel a lot less intimidating. I never realized how versatile shiitakes are—they’re not just great in stir-fries but can really elevate any dish with their unique umami flavor. I particularly appreciated the section on choosing the right logs and the importance of moisture levels. I’ve got a few oak logs sitting in my yard that I think will be perfect for this. Also, the tip about inoculating the logs in the spring was super helpful; I’d have probably messed that up! I’m excited to give this a try and hopefully have my first harvest by summer. I’ll keep you posted on my progress and share some pictures when they start popping up. Do you have any tips on what to do if they don’t seem to grow as expected? Thanks again for sharing your knowledge, it’s nice to have a resource like this to refer to. Happy mushrooming!
Hey Josh, I just finished reading your guide on growing Shiitake mushrooms, and I have to say, it's incredibly informative! I’ve always been curious about mushroom cultivation, but the process seemed a bit daunting until now. Your step-by-step instructions made it feel manageable and even exciting. I especially appreciated the tips on choosing the right substrate and the importance of maintaining humidity levels. I never realized how crucial those factors were for a successful yield. I also loved the section on troubleshooting common issues - I’m sure that will save a lot of us from potential headaches! I’m planning to dive into this project over the weekend, and I couldn’t be more pumped. Also, if I manage to grow a nice batch, I’ll definitely share some photos to show my progress. Thanks for breaking it down in such an easy way. Can’t wait to taste my own homegrown Shiitakes in some stir-fry soon. Keep up the great work with ShroomSpy, and I look forward to more of your guides in the future!
Hey Josh, thanks for the detailed guide on growing Shiitake mushrooms at home! I've always wanted to try my hand at home cultivation, and your step-by-step instructions make it seem so accessible. I especially appreciate the tips on choosing the right logs and the importance of moisture control. I never realized how much of a difference that could make in yield and flavor! I’m a bit nervous about getting the inoculation process right, though. Do you recommend practicing on smaller logs before committing to larger ones? Also, if I wanted to incorporate Shiitake into my weekly meals, any suggestions for simple recipes? I’ve heard they’re quite versatile and bring a lot of depth to dishes. Lastly, I’d love to hear about any issues you’ve faced in your own Shiitake growing experience and how you resolved them. It’s always comforting to know others go through the same hiccups! Looking forward to my mushroom adventure, thanks for inspiring me to get started! Cheers, Sam
As someone who recently ventured into growing my own mushrooms, I can't recommend the ShroomSpy Guide to Growing Shiitake at Home enough! Josh Shearer's insights and step-by-step instructions made the whole process feel manageable and fun. The guide breaks down everything from choosing the right materials to harvesting your shiitake, and it’s packed with practical tips that really demystify the entire experience. I particularly enjoyed the section about the best wood types to use; I didn’t know that the choice of substrate could affect the flavor and yield so much! I started with a small kit and was blown away by the first harvest. The shiitake mushrooms turned out to be flavorful and fresh – so much better than anything you find in the grocery store. Plus, growing them myself made for a rewarding experience that I’ll definitely continue. If you're considering trying your hand at growing shiitake mushrooms, do yourself a favor and check out this guide. It’s approachable, informative, and has a great community vibe that makes you feel like you’re not just growing mushrooms but also being part of something bigger. Thanks, Josh!
I've been growing shiitake mushrooms at home for about a year now, and I can't recommend it enough! Josh Shearer's guide is incredibly helpful, especially for beginners looking to get into mushroom cultivation. I found the section on selecting the right wood logs especially useful. I had no idea that using hardwoods like oak or sweetgum could make such a difference in yield and flavor. The step-by-step instructions made the entire process straightforward, even for someone like me who's not particularly handy. Plus, I love how rewarding it is to harvest your own mushrooms fresh from the garden! It's not just about the taste—although they are delicious. There’s something truly fulfilling about growing your own food, and shiitakes have become a staple in my kitchen. I also appreciate the tips on maintaining humidity levels. I initially struggled with that, but after implementing the advice here, my growth rate has improved significantly. If you're on the fence about starting your shiitake project, read this guide and give it a shot. You won't regret it. Happy growing everyone!
