Cracked corn from Tractor Supply Co.

[elvis christ]

So I got 50lbs of cracked corn from Tractor Supply Co, and my mash hasn't been working very well since then. I've read some stuff about air dried vs gas dried corn, and was under the impression that gas dried corn was no good for mash. I also read about preservatives, and called a Tractor Supply Co in Nebraska (who better to ask about corn, right?), and they told me there were no preservatives in the corn. So I'm wondering if this corn is no good for mash. Anyone else have any experience/wise words as far a what kind of corn to use? I don't want to start using corn meal, as it's expensive, but so far that's what I've had the best results with. Thanks in advance. _jeff
