You can use the quart jars for measuring. I usually rinse off the grains before loading them in the quart jars. Scoop enough grain so that each jar is evenly filled. Shake the jars when removing them to mix up the grains. If the jars have not colonized within 14-21 days the jar is most likely contaminated or the temperatures are too low.

Grain to Grain Transfer
When a Quart Rye Jar is fully colonized it can be used to inoculate up to 10 more jars to expand your mycelium and increase substrate mass thus increasing yields. A rye jar usually colonized in about 3-4 weeks. The Procedure: Reshake the colonized jar to break up the grains. To inoculate the new rye jars, remove the lid from your colonized jar and the lid from the fresh substrate jar. Shake some colonized rye grains into the fresh substrate.
Continue with the rest of the jars. Remove the lid, quickly inoculate with rye grain and replace the lid.

• Use each jar to inoculate 10 more jars each
• Fruit the mushrooms right out of the top of the jar (depending on your species; not all mushrooms fruit directly from grain)
• Use the colonized grain to inoculate any of our 3 lb Substrate Spawn Bags.
• Use the colonized grain to inoculate Pasteurized Straw
