This is my first time growing oysters.

looks like Tupperware? If a plastic-type holder is being used and your mushrooms dry out while forming, try putting a small amount of water in the bottom of your container: maybe 1/8 inch or so. When the block absorbs the bottom water, you’ll know it’s time to add some more. If these are P. eryngii, they will be 80-90% water by weight, so important to have LOTS of water available to the kit.

Enlarged bottom of stipe suggests P. eryngii to me.

Given some additional added air and maybe some additional misting, might well be. A lot of King Oysters reach 6-8 inches tall and have a huge base. Readily available in my local Korean food store.

We’ve been covering them with a plastic bag with holes in it to keep the humidity up, but we’ll let them breathe a bit more. Our first flush dried out, so we’re still trying to find that balance.

if you give it

more fresh air you will get larger caps. This is fairly common look of formation of a pleurotus species growing in an environment with elevated levels of CO2.
