I know that rye grain is often recommended - and it makes sense for commercial growers who can get lots of cheap rye grain and who have mastered the process of hydrating and sterilizing rye. But I have personally moved back to popcorn kernels... I can buy them at my local shop, it is easy to hydrate them to the right level, and I have less contamination. I mention this because I read that you are "waiting to receive some rye grain" - which sounds like you may have ordered it online! Consider that you can get similar or even better success with the grains that are readily available.
If you have any doubts about contamination you can post some photos and I might be able to help!
Cool! Good luck!! It is super fun :-)
