First I cut and prefolded the parchment paper with double or triple folds on the edges and tightly creased. I wrapped my pouches in foil and baked 250F for 60min. This may be unnecessary but I didn't want to take chances. When it was time, I shook the donor jar to break up the grains, removed a pouch from the foil, opened it up and poured the grains in. I closed the pouch up then, broke the rest of the grain clumps so they fit into a single layer. I wrapped the pouch in a double layer of paper towels and placed a 1/2 pint large mouthed jar on top. I swapped out the paper towels every other day because they'd get damp. It took 7 days for the agar and grains to dry.
The agar was dried much the same way as the grains above. The agar was cut down the center. Then, it was folded in half with the myc touching myc and placed in a parchment pouch to dry.
I also made jar lids with parchment paper, held in place with metal bands. These had less grains but took about 10 days to dry.
The agar and grains were dried open air, in a file box, being pressed by jars of PF Tek. What made me most optimistic was the fact the agar stained the inside of the parchment paper but not the outside nor the paper towels. I placed a dried grain to agar and a flake of dried mycelium to agar too. After about 10 days, both look pretty healthy and strong.
I was originally going to store some dry grains longterm in 5ml cyrovials maybe with some wine preserving gas? I'm thinking now, I may just vacuum seal them?
