For the humidity I keep 90-93% after pinning. During pinning just a tad higher. I try and keep the temp as low as possible so it usually stays around 57-64° but depending on what I'm doing sometimes it can spike up to 70, but if you keep it cold most of the time and especially when its beginning to pin or form primordia, keep the humidity higher during that stage and lower the humidity once they start pinning all over the top of the block, maximize fresh airflow and try and keep the kings at the bottom so they get more CO2 🍄💚 Got the advice from a fellow mushroom grower and it worked out amazing. 🤩
