Theres a tek on shroomery where colonized rye goes directly into the pan cased and incub for 3-5 days. Then to FC.
What is gained by taking the extra step to colonize straw and then case. Is it yeild?
The speed to FC sounds really appealing.
the trade off is that you only get one good flush, maybe two, because the myc will use up the food in the grain faster, most of the time and trich will set up quick if your not real careful. you can add field cap verm to the rye by mixing it well in a ziplock bag, get it EVENLY mixed and it colonizes in three days, it will pin ten days after that. but the booms are mostly water and dry out lighter, theres always a trade off. the extra three or four days to colonize poo or straw is worth it.
Casing grains def works, I love giving them some straw and H poo to munch on though.
