Grain spawn.

I'm new to the hobby. I have a little over a year of experience. I have tried a lot of different products. Seeing what works for me and doesn't
Alot of products are amazing and some are gemics.
I recommend corn that works best for me but this is my always go to grain spawn. I recommend anyone to at least purchase 1 jar and try it.

I tried 1 jar and order a bunch a week later.
