4 Steps to Making Grain Spawn Step 1: Rinse and clean the grains, soak in water for 12-24 hours. Step 2: Cook the grains for 15-20 minutes so that they absorb water. Step 3: Drain and dry excess moisture from the outside of the grains. Step 4: Load grain into mason jars and sterilize for 90 minutes at 15 PSI.
What is the best grain for mushroom spawn?
Most people consider rye to be the best grain for mushroom spawn. It is nutritionally dense, holds plenty of water, and has relatively small grains with a large surface area. A large surface area is advantageous because it means more inoculation points for the mycelium.
How do you get perfect grains to spawn?

Do I need to soak mycelium?
Especially with the dry climate in Colorado, the mushroom mycelium needs a good amount of water to produce large healthy mushrooms. We suggest that you try to soak your block between every harvest. Place the bag with the hole you made facing down into a bowl or pitcher with distilled or filtered water.
Do I need to soak grain spawn?
The first step to making grain spawn is to soak some cereal grain. Soak the grain by simply placing it in a bucket or bowl, covering in water, and leaving it for 12 -24 hours. If you leave the grain for too long, it will eventually sprout- so try not to soak it for more than 24 hours or so.
How do you make homemade mushroom spores?
Lay the cap on a white piece of paper or index card with the gills or pores on the bottom of the cap facing down. If collecting spores from a large mushroom cap, you may cut the cap into sections, placing only one section on the paper; use multiple pieces of paper to collect spores from multiple sections if desired.
Can you overcook grain spawn?
Grains should not be overcooked or too soft. Dirty or overcooked grains can stick together, making it difficult for mycelium to grow and/or later be broken up during spawning.
How can I speed up mycelium growth?
How to Boost Mycelium Growth Ensure that the medium in which the mushroom is being grown is sterile. Use only fresh agar agar to start the mycelium in this type of growing medium. Plan the correct location for the mushrooms. Keep all wildlife and some insects away from the growing area.
How do I grow mycelium at home?
Step 1: Prepare the Growing Environment. Cut the cardboard into pieces that fit well into the container. Step 2: Cut Pieces of Mushroom. Take your mushroom and scalpel to cut tiny slices of the base. Step 3: Add the Layers. Step 4: Store and Grow. Step 5: Watching It Grow.
How do you make a mushroom Monotub?
How to Grow Mushrooms Using the Monotub Method STEP ONE – Purchase your tub. STEP TWO – Line your tub. STEP THREE – Create holes in a tub for airflow. STEP FOUR – Cover holes with micropore tape to prevent contamination. STEP FIVE – Sanitize all materials. STEP SEVEN – The “Spawn Run”.
How do I Sterilise grain without a pressure cooker?
How to sterilize mushroom substrate without a pressure cooker Composting. Chemical. Coldwater pasteurization. Hot water immersion (Scalding) Pasteurization. Tyndallization.
How do you make grain bags?
Steps to prepare grain spawn for your mycelium Soak your grain in hot water. Let the grain sit for 12-24 hours. Test the grain by pinching it to see that the grain separates when properly hydrated. Drain excess moisture from the outside of your grain. Load the grain into your spawn bags.
When can I use grain spawn?
You should be ready for your grain spawn before it arrives. The quicker you use it, the better your chances of success. Depending on the growing method you choose, this means having a bulk substrate ready for sterilization or pasteurization, and having a fruiting container with a place to fruit it.
Is millet a good grain spawn?
Millet is an ideal grain for spawn production and supplementation. Millet has a much lower endospore load than rye and wheat, making it less prone to contamination, and its small size means that your spawn will have many more inoculation points for the same volume of grain.
How do I make sorghum spawn?
Steam sorghum seeds for 30-45 minutes to soften grains and cook about 25%. Drain water and spread sorghum seeds to cool down and decrease moisture. Fill ¾ of bottle with sorghum seeds. Tightly plug mouth of bottle with cotton and leave out for ventilation.
How long does it take mycelium to colonize grain?
Generally speaking the optimal time is 16 to 19 days, but there are certainly also exceptions. If the compost is colonised in the growing room, it is left there so the mycelium stays intact.
How long does it take grain spawn to colonize?
Some strains can take 60 days+ to fully colonize while others can take as little as 25! Fully colonized 5-Grain spawn bag rotated on its side. When your spawn bags are about 20-30% colonized or around 12-18 days, you can use this technique to speed the overall growth of the bag.
