grain substrate
« on: April 02, 2013, 07:41:18 PM »

I have grown several experiments with purchased grain substrate.  I want to try sterilizing my own.  I have followed instructions from a book but the grain looks way too moist.  When I buy it it almost looks dry. 

Are there any good instructions on how to prepare grains before sterilization?

I rinse the grains 3-4 times. Soak for 24 hrs. Then bring to a rapid boil and time it for 10 mins. Put grain in strainer and shake every 15 mins for 1 hr. Works for me! :mellow:

I rinse them until the water is clear. Put it in a pot and fill it up with water an inch or two above the grains, bring to a boil and simmer until you see a noticeable increase in size.

Here is a little trick when using corn.  Just buy a can of cooked corn at the food Store.  Its alread well sterilized.  Just pour off liquid, and put it in sterile jars.  slp/fmrc

Did you actually try this? The canned corn is salted, can mycelium cope with that?

Been doing it for years.  It has always worked with many different species.  You can buy health food brands without salt if that worries you.  slp/fmrc
