🍄 How to Prepare Malt Extract Agar (MEA) for Mushroom Cultivation
✅ What You’ll Need:
Ingredients (Standard 1 Liter Batch – Makes ~35–40 Petri dishes):
- Malt Extract: 20 grams
- Agar-Agar Powder: 15 grams
- Distilled Water: 1000 mL
- (Optional: Peptone 1–2g or yeast extract for additional nutrients)
🥣 Step 1: Mixing the Ingredients
- Measure out 20g of malt extract and 15g of agar powder.
- Add both to a clean 1-liter Erlenmeyer flask or heat-safe container.
- Pour in 1 liter of distilled water.
- Stir well until all solids are dissolved. Use a magnetic stirrer or manual stirring. The solution may be cloudy.
🔍 Tip: If you're using powdered malt extract, mix slowly to avoid clumping.
🔥 Step 2: Sterilization
- Cover the flask with aluminum foil or a loose cap — not airtight.
- Place it in a pressure cooker or autoclave.
- Sterilize at 15 PSI (121°C / 250°F) for 20–30 minutes.
⚠️ Do not exceed 30 minutes to avoid caramelizing the sugars in the malt, which may inhibit fungal growth.
❄️ Step 3: Cooling
- Allow the sterilized MEA to cool to around 50–55°C (122–131°F). It should still be liquid but not too hot to kill spores if pouring into inoculated media.
- If using a thermometer, monitor closely. This is the ideal pouring temperature.
🧊 Do not wait too long — it will start to solidify around 40°C (104°F).
🧪 Step 4: Pouring Plates
- Sanitize your work area thoroughly or use a laminar flow hood/still air box.
- Pour ~20 mL of agar into each sterile Petri dish.
- Slightly crack the lids and let them sit for 15–30 minutes until solid.
- Once solidified, close the lids and allow the plates to fully dry for 24 hours before sealing.
- Optional: Store plates upside down to prevent condensation from dripping onto the surface.
🧼 Label your plates with date and medium type.
📦 Storage Instructions
- Store sealed plates in ziplock bags or parafilm-wrapped stacks
- Keep refrigerated at 2–8°C (35–46°F)
- Plates are viable for up to 4–6 weeks if properly stored
🌱 Optional Additions & Notes
- Antibiotics (e.g., gentamicin) can be added after cooling (below 50°C) to prevent bacterial contamination
- Activated charcoal (0.5g/L) can be added to promote some fungal species
- Color indicators can be added for pH sensitivity, though not usually necessary for mushroom work
🍄 How to Prepare Liquid Culture (LC) Jars for Mushroom Mycelium
Liquid culture is a sterile sugar-water solution used to grow mycelium for easy inoculation of grain, agar, or other substrates. It enables fast, clean, and efficient propagation of fungal cultures.
✅ What You’ll Need
Ingredients (Standard 500 mL Batch):
- Light Malt Extract (LME): 10 grams
(Alternative: Karo Light Corn Syrup – 4% concentration or 20mL per 500mL water) - Distilled Water: 500 mL
🥣 Step 1: Prepare the Liquid Culture Mix
- Add 10 grams of light malt extract (LME) to 500 mL of distilled water in your jar.
- If using Karo syrup, add 20 mL per 500 mL water.
- Mix thoroughly to dissolve all sugars. Use a stir rod or magnetic stirrer for even mixing.
- Add a magnetic stir bar to the jar if you plan to use a stir plate later (optional but recommended).
🔍 Tip: Use clear jars to visually monitor mycelium growth and contamination.
🧴 Step 2: Jar Setup & Lid Prep
- Use a lid fitted with:
- Self-healing injection port (SHIP) for inoculation
- Micropore filter or synthetic filter disc for gas exchange
- Tighten the lid lightly to allow some venting during sterilization.
- Cover the top of the jar with aluminum foil to prevent condensation or water from the pressure cooker entering the lid.
🔥 Step 3: Sterilization
- Place your LC jar into a pressure cooker or autoclave.
- Sterilize at 15 PSI (121°C / 250°F) for 20–25 minutes.
- Longer sterilization can caramelize sugars and darken the solution.
⚠️ Always keep jars upright and avoid overfilling the pressure cooker with water. Use a rack or trivet inside.
❄️ Step 4: Cooling
- Let the jar cool fully to room temperature before use (may take several hours).
- Do not inoculate while warm — it will kill your spores or culture.
💉 Step 5: Inoculation (In Sterile Conditions)
- Use a still air box or laminar flow hood.
- Sterilize a syringe needle with flame or alcohol.
- Inject 1–2 mL of spore solution or agar wedge into the LC through the SHIP.
- Optionally swirl gently or place on a magnetic stir plate for 30 mins daily.
🧬 Step 6: Incubation & Growth
- Incubate at 21–25°C (70–77°F).
- Shake or stir once daily to prevent clumping and increase oxygenation.
- Mycelium should begin showing in 3–7 days, fully colonized in 10–21 days depending on strain and environment.
🧪 Monitoring & Use
- Look for cloudy, web-like mycelium suspended in the liquid.
- Discard if you see:
- Sediment or grainy debris
- Smell of rot or sourness
- Color other than white (green, black, pink = contamination)
Once colonized, the LC can be used to:
- Inoculate grain spawn
- Transfer to agar
- Create additional liquid culture jars
📦 Storage Instructions
- Store at room temperature if in use
- For long-term: refrigerate for up to 2–3 months
- Always flame sterilize the needle before every use
Spawn Instructions
Supplies Needed

🍄 Hardwood Substrate Preparation for 10 lb Mushroom Grow Bags
Supplemented Sawdust Blocks using Hardwood Pellets
This method is commonly used for wood-loving gourmet mushrooms and is ideal for home or small commercial cultivation using autoclavable mushroom bags (unicorn-style filter bags).
✅ Ingredients (Per 10 lb Substrate Block)
To make one 10 lb block (~4.5 kg wet weight), use:
- Hardwood fuel pellets (compressed sawdust): 5 lbs (~2.27 kg)
- Water (filtered or distilled): ~1.4 gallons (5.3 liters)
- Wheat bran (or soy hulls): 1 lb (450 g)
- Optional gypsum: 1–2 tbsp for pH and structure
🌱 This mix gives you a ratio of 80% hardwood + 20% supplement (by dry weight), ideal for most wood-loving mushrooms.
🥣 Step 1: Measure & Mix Ingredients
- In a large clean container or tub, add:
- 5 lbs of hardwood pellets
- 1 lb of wheat bran
- 1–2 tbsp gypsum (optional)
- Slowly pour in hot or boiling water — around 1.4 gallons total.
- Mix thoroughly. The pellets will break apart and rehydrate into sawdust.
- Let it sit 20–30 minutes, then mix again until consistent.
✅ The substrate should be moist but not dripping — aim for field capacity: when squeezed, it releases just a few drops of water.
🧴 Step 2: Load Mushroom Bags
- Use large gusseted autoclavable filter bags (e.g., Unicorn 14A or XLS-A).
- Fill each bag with around 10 lbs wet substrate (~4.5 kg).
- Leave at least 4–5 inches of headspace for folding.
- Compress the substrate slightly to remove large air pockets.
🔥 Step 3: Fold and Seal for Sterilization
- Fold the top of the bag down accordion-style and secure with:
- Impulse sealer, or
- Bag clamp (remove post-sterilization before sealing)
- Make sure the filter patch remains uncovered — it must stay breathable.
- Cover the top loosely with aluminum foil to prevent condensation drip during sterilization.
💨 Step 4: Sterilization
- Place bags upright in a pressure cooker or autoclave (do not stack tightly).
- Sterilize at 15 PSI (121°C / 250°F) for 2.5 to 3 hours.
- Full sterilization is critical to eliminate competitive organisms in high-nutrient blocks.
- Let cool fully to room temperature before moving or inoculating.
🧬 Step 5: Inoculation (After Cooling)
- In a still air box or flow hood, cut open or unseal the top of the cooled bag.
- Add:
- 5–10% grain spawn by wet weight (0.5–1 lb of spawn per 10 lb block).
- Mix gently but thoroughly inside the bag by massaging or shaking.
- Seal the bag using an impulse sealer or fold/clamp method.
🔍 Make sure the spawn is evenly distributed through the top third of the block for best colonization speed.
🌱 Step 6: Incubation
- Store bags in a dark or dim environment at 68–75°F (20–24°C)
- Full colonization typically takes:
- 2–3 weeks for fast colonizers (e.g., lion’s mane, oyster)
- 4–6 weeks for slower types (e.g., shiitake, chestnut)
- Watch for full white colonization, followed by primordia formation inside or outside the bag depending on species.
🧪 Contamination Watchlist
Be on alert for:
Type | Symptoms |
|---|---|
Trichoderma (green mold) | Green, fuzzy patches; rapid growth |
Bacterial slime | Wet, sour-smelling substrate |

🍄 Shiitake Mushroom (Lentinula edodes) — Primordia Initiation & Fruiting Guide
For Fully Colonized 10 lb Supplemented Hardwood Blocks
🧬 1. Observe Colonization Progress
Shiitake colonizes substrate below the surface first, which can be misleading.
✅ Key colonization phases:
- Weeks 1–3: White mycelium spreads internally, little surface change
- Weeks 3–4: Entire surface is visibly white and cottony
- Weeks 4–6+: Mycelium begins to brown (metabolite pigmentation) as it matures
🔍 Browning = maturity, not contamination. This is a natural hardening of the block’s surface and is essential before fruiting.
⏳ 2. Timing: Wait for Full Browning (Crucial for Shiitake)
Before initiating primordia, your 10 lb shiitake block should:
- Be 100% colonized (no visible substrate)
- Show deep golden-to-cinnamon brown coloration
- Appear dense and firm to the touch
🕒 This can take 6–8 weeks post-inoculation, depending on the strain and environment.
🧊 3. Cold Shock to Trigger Primordia
Unlike many other species, shiitake requires a temperature drop (“cold shock”) to initiate pin formation.
❄️ Cold shock process:
- Remove the plastic bag entirely once the block is fully colonized and browned.
- Submerge the exposed block in cold water (35–45°F / 1–7°C) for 4–12 hours.
- Use a clean tub or sink
- Ensure full submersion (weigh it down if needed)
- Remove and drain for 15–30 minutes.
⚠️ Do not soak early or for too long — this may damage the block or lead to contamination.
🌱 4. Move to Fruiting Environment
After the soak, transfer the block to a high-humidity fruiting space, such as:
- A grow tent
- A shotgun fruiting chamber
- A humidity-controlled room
Ideal fruiting conditions for shiitake:
- Temperature: 55–70°F (13–21°C)
- Humidity: 85–95% RH
- Lighting: 12 hours/day, 6500K spectrum
- Fresh Air Exchange: High — at least 4–6 air exchanges/day
👁️ 5. Watch for Primordia Formation
Primordia (baby mushrooms) begin forming in 3–7 days post-soak.
Signs you're on track:
- Tiny dark-colored bumps appear on the block
- They quickly grow into small, brown dome-shaped caps
- Block remains firm, not soggy or discolored
Fruiting Instructions
Supplies Needed
- Fruiting Chamber: Controlled environment chamber for fruiting.
- Temperature Control System: Equipment for maintaining optimal fruiting temperatures.
- Fresh Air Exchange System: System to provide adequate fresh air exchange in the fruiting chamber.
- Light Source: Light source to provide required illumination for fruiting. (e.g., LED Grow Light)
- Harvesting Tools: Tools for harvesting mushrooms without damaging the mycelium. (e.g., Knife, Scissors)

🍄 Shiitake Fruiting Guide (Lentinula edodes)
For 10 lb Supplemented Hardwood Substrate Blocks
Phases, Environmental Control & Harvesting
Shiitake mushrooms fruit in distinct biological phases that require specific changes to temperature, humidity, light, and fresh air exchange (FAE). Managing these phases properly ensures strong flushes, dense fruit bodies, and multiple successful harvests.
🌱 PHASE 1: Browning & Consolidation (Pre-Fruiting)
Duration: ~4–6 weeks after full colonization
Environment: 70–75°F (21–24°C), dark or low light
What's happening:
- Mycelium finishes internal colonization
- Surface transforms from white to golden-brown (“skin” forms)
- Block densifies and builds fruiting potential
✅ Key Signs to Wait For Before Fruiting:
- Surface fully browned and hardened
- No white mycelial regrowth or exposed substrate
- Block has a firm, leathery feel
- Colonization period complete (minimum 40–45 days)
⏳ Patience is key — premature fruiting = weak or aborted mushrooms.
❄️ PHASE 2: Cold Shock & Soaking (Initiation Trigger)
Timing: After browning is fully complete
Trigger Method: Cold water soak
Procedure:
- Remove block from the bag (or cut large slits if bag-fruiting)
- Submerge in cold clean water (36–45°F / 2–7°C) for 4–12 hours
- Weigh down if necessary to ensure full contact
- Drain thoroughly and allow excess moisture to drip off for 15–30 min
Purpose:
- Simulates rainfall and seasonal drop in temperature
- Triggers primordial (pin) formation
💧 Do not soak early — it may lead to rot or contaminate the block.
🍄 PHASE 3: Pinning & Fruiting
Duration: ~5–10 days
Environment:
- Temp: 55–70°F (ideal: 60–65°F / 16–18°C)
- Humidity: 85–95% RH
- Light: 12 hours/day of indirect light, 6500K (avoid total darkness or direct sun)
- FAE: High — shiitake needs clean, moving air to fruit properly
What to watch for:
- Dark brown bumps appearing across the block (primordia)
- Rapid development into button-sized caps
- Mushrooms double in size every 24–48 hours during peak growth
✅ Keep the block moist, but not soaked. Mist walls or air above the block as needed.
✂️ PHASE 4: Harvesting
Ideal Harvest Time:
- Cap is expanded and slightly convex, not fully flat
- Veil under the cap is torn, but spore drop hasn’t started
- Mushroom feels firm and heavy
- Color is rich brown (strain-dependent)
Harvesting technique:
- Twist and pull gently from the base
- OR cut cleanly with a sanitized knife or scissors
- Avoid damaging nearby pins — harvest in clusters where possible
⛔ Overmature shiitake become spongy, release spores, and are prone to rot.
🔁 PHASE 5: Rest & Re-soak for Future Flushes
After harvest:
- Remove stem stubs and surface debris
- Let the block rest in fresh air for 7–10 days (no soak)
- Re-soak in cold water for another 4–12 hours
- Resume fruiting conditions
📦 A healthy shiitake block can produce 2–4 flushes, with second and third flushes often larger and more attractive than the first.
🧪 Common Issues & Fixes
Issue | Cause / Fix |
|---|---|
No pins after soaking | Block not mature enough – wait longer before next soak |
Mushrooms abort or are misshapen | Insufficient FAE or excess CO₂ — increase airflow |
White fuzz on caps | High humidity and low airflow — adjust FAE |
Mushrooms too pale | Not enough light — ensure indirect 6500K exposure |
Mushrooms drying out early | Low RH — mist more or use humidity tent |

The tips about the substrate and humidity levels were especially helpful for me as a beginner. I also learned a lot about the importance of sterile techniques which I didn't consider before. I'm planning to set up my first grow this weekend, and I feel so much more confident thanks to the information shared here. I can’t wait to harvest my own delicious King Oysters and incorporate them into my meals. Plus, I've always appreciated cooking with fresh, homegrown ingredients. This guide has truly inspired me. Looking forward to sharing my progress and hopefully some photos of the fruits of my labor soon. Thanks again, Josh, for sharing your expertise with us! Anyone else here trying their hand at growing these beauties? Let’s cheer each other on!
I've been experimenting with growing mushrooms at home for a while, and I just had to chime in about the King Oyster! Josh, your guide really breaks things down in a way that’s easy to follow. I tried your humidity tips, and they made a massive difference in my flush! The meaty texture and unique flavor of these mushrooms are out of this world, especially when sautéed with garlic and butter. I’m not a pro, but I can say that patience is key with these beauties. I initially made some mistakes with the substrate, but after tweaking it according to your recommendations, I finally got it right! I also found that keeping the temperature consistent helped a lot. Would love to hear if anyone else has put their own twist on the growing conditions or recipes. Can't wait to try again and perhaps incorporate more advanced techniques, like using a grow tent. If you’re on the fence about growing King Oysters, just dive in – it’s well worth the effort! Thanks again for such a thorough guide, Josh! Looking forward to sharing more experiences with everyone here. Happy growing!
