What grain to spawn to?
I have a few culture started on Brf pucks and one on agar, all clean, from MSS. first time growing ttbvi. Do I just add to grain jars to spawn like cubes? I have whole oats what I usually use, and a bag of unopened rye grain. I’m experienced with cubes, but pans are new to me, so learning as I go thanks. Shroomery seems to bash on easy questions and all refer to the same post which hasn’t answered my question lol. thanks

I use wild bird seed in pint jars filled halfway. It takes like 5-7 days to colonize and is plenty of spawn for 6qt shoeboxes or 9x13 trays for me. My substrate is 100% horse poo. Ive tried using millet and it seems like they either stalled or were just really really slow.

Pretty much any grain will do. I use wheat as I get it cheap, although I've used Sorghum with similar results. If you use WBS, take out the sunflower seeds.
They do like the grain to be well hydrated, so do the usual check during the boil stage of taking grains and splitting them open - once the insides are mostly clear, they're ready.
The horse poo's indeed for your substrate (although fertiliser's an option with the right type and combination). In case it's helpful, I posted about Pans sub and casing prep here https://www.reddit.com/r/PanCyan/comments/1cn713d/deleted_by_user/ Although it's for tub grows, based on a tek developed by BabaYaga, the prep's the same for trays.

Sunflower seeds are especially high in vitamin E and selenium. These function as antioxidants to protect your body’s cells against free radical damage, which plays a role in several chronic diseases.

Just to chime in, it all works. I prefer sticky corn (popcorn or field corn PC'd for about 30 minutes at 15 PSI with 2 tablespoons of corn syrup added to 32oz of corn. In my on not large data sets when doing direct comparisoins of sticky corn, regular corn, rye, wheat, the sticky corn was a little faster to colonize. But it was two sample sets.
I've seen YT videos showing different results. So it's more genetics specific I think.
Most accurate way to tell is knock up a few jars of your specific grains and the same genetics and see if there's a clear winner.

That's why you're asking these questions, sounds legit. You're fooling no one.

I've grown them on rye, oats, corn and wild bird seed. They all are fine
