How much milk do you add to grains? I eyeballed/poured what I thought was maybe 10CC's, but my jars are soaked!
I fill mine until the grain is submerged. The key is extracting all the water or most of it and this especially true when using grains like oats which i typically use. I honestly don't know why i have not went exclusively with popcorn for glc purposes. I supposed out of convenience. I always prep more oats then i need for working spawn so the extra gets turned in to masters.
The less water you use, the more difficult or more effort it takes to get the mycelium off the grains but you end up with a higher myc/water ratio. I suppose one could look at it like this.......how many bags/jars would you expand a single jar to? For simple conversation, lets say 1 quart jar to 10. How many cc's of liquid inoculate would you use to inoculate 1 jar? Lets say its 5. You need 50 cc's of solution and you should anticipate loosing at least 10% of water. So in this example i would use inject 55 cc of water.....screw it round up to 60 because you would probably lose more then 10% on a full jar of grain. Note you can get a second pull if you dont get enough your first time.
Hyphe probably has his own calculations he uses but at the end of the day, its about getting as much water out of that jar as possible so that the popcorn can rapidly recover. Oh and i always lay the grain jar on its side after being milked so it lessens the depth of the water pooling up and it gets absorbed quicker. Most of my experience is with oats. I only used popcorn when replicating his agar/popcorn jars. So it may be slightly different when using popcorn repeatedly for milking. I do agree that popcorn is the best grain to use for GLC purposes.
