Cracked Corn Substrate Preparation.

Cracked Corn Preparation Technique:

Cracked Corn is an alternative to millet or popcorn.
It is easy to find and is about one third the cost of millet.
It can be found at Pet stores as bird feed and also at Feed stores.
In this tek we will use CC for short.

Note: Upon cooking the CC expands *approx* 2x.

1. Get the estimated amount of CC you want and put it into a large pot.
Next cover the corn with water and set the heat between "medium" and "high".
Stirring the pot often.

2. Simmer the CC 30 - 35 minutes on the stove
is enough time, however it depends on how much you are doing and how much
water/corn you are working with etc..
(with small amounts the heat may need to be adjusted lower to prevent boil over)
For large batches this time was correct.

3. Look for the corn to "change", it gets a slime coating on the outside.
CATCH THIS! Do not let it go past this point! As soon as you see the slime coat, take the heat off
and set the pot by the sink. Have a bucket or large bowl in one bin
of the sink and use the other bin of the sink as a work area.
Scoop out enough corn to fill the strainer and run COLD water over the corn THROUGHLY,
then let it drip for a sec... then it goes into the bucket.
Also you can add a percentage of vermiculite (field capacity) to this mix for a good moisture buffer.

You could go right to the jar here...

Or

Take the strained corn and transfer into a new bucket , each time filling the strainer with corn and
rinsing again. Tap it on the sink to get out as much water as possible.

Then transfer it into the new bucket/bowl.

Fill the jars half full, this will allow for easy shaking of the jars after pressure cooking.

Pressure cook for 90 minutes @ 15 PSI
Let cool to 0 PSI with gloves/mitts shake the hot jars to mix the wetter kernels with the drier ones.

Cool to room temp in a relatively sterile envioronment, and inoculate
2.5 cc of spore solution is recommended for each QT jar.
Incubate per strain specifications.

Best of luck.

This is millet, cracked corn, and whole corn.

Here are quart jars after 8 days colonization.
CC with a dash of coarse vermiculite.

Quart jars of millet after 8 days colonizaton.

The results are obvious, the CC colonizes over 3 times as fast as the millet!

Best of luck!
