Here’s what someone else did with a shiitake kit! They used a metal holder of some kind they already had to hold the block upright, then used a plastic (so no rust) tomato trellis wrapped in clear plastic as a humidity tent. Seemed to work out pretty well!

…and when they went to move it, found a couple fruits they didn’t even know they had.
Counting the four mature fruits that were picked before these photos were taken, I’d consider this a full flush from a 2.5lb shiitake block. Now it’s time to dry it out, soak it, and go for another! They informed me the result was delicious with pasta in a simple sauce with basil, topped with parmesan.
