Conlon is a good variety for malting.

Perhaps I misspoke, I should have said it doesn't matter if the shoots stick out it only matters that their length is 75-100% the length of the kernel.

Cleaning is done with a fanning mill, however it seems your friend has their combine adjusted well.

How dirty was the cleaning water initially?  Normally goes from blackish to almost clear or off yellow.

Apologies, I'll quit asking questions.

You're lucky to have a source for the barley such as your friend.  I'm sure your beer will turn out great!

No problem sir, I understand what you mean. 

The initial water was a bit yellow, which I then drained and filled a few times using my mash tun.  I wish I had done it in a bucket first as it would have been easier to tip and just let the chaff and such run off over the edge.  The  official first soak did take on some "yellow" again by the end but not too bad, and the subsequent soaks were much better.
After the final drain, I did find maybe a teaspoon of dirt in the bottom of the mash tun that my "Denny Conn" filtration braid kept from draining out.  ;D

Third and final soak before draining


After a day you can see rootlets.

As mentioned above, you want to mash with very low alkalinity water (ie: distilled water preferrably) and at a typical water/grist ratio. The primary grain you need to check are the base malts since they tend to make up a large portion of the grist and have the greatest impact on overall mash pH.

Thanks Martin,
I'm obviously missing something as I don't understand the object of testing base malt in distilled water (other than to compare it to other base malt) while on brew day I will not be using distilled water, nor will I be using just base malt.
It's my shortcoming and I'll sleep on it and reread this tomorrow and maybe I can fill in some gaps. :-[

Thanks everyone,

If you're more of a technical person and have a basic understanding of water chemistry reading this may give some insight:
