"Be careful growing those indoors, especially if it's your bedroom where you spend many hours per day. It doesn't take but a few years to develop the allergy to oyster spores." (source; also has more details about his severe reaction to them)

"Wear a respirator from day one. It takes a year or two for the allergy to develop if you're exposed a lot. My mistake was using a mini-greenhouse in my bedroom, where I was exposed to the spores all night while sleeping."

"It took about six months of having them in my bedroom daily to get the allergy. I had grown them for at least a decade before that, but in a separate area where I only got exposed when tending them. However, once the allergy developed, I can't even go into a grow room for two minutes if there's an oyster spore load there."

symptoms and how the allergy develops; a bit more info

so many spores they clog an A/C unit

his cautionary tale

"Furthermore, after a few years of growing oyster mushrooms you will be so allergic to the spores that you'll have to wear a full face respirator just to enter the grow room." (source)

"Oyster spore allergy takes a few years of heavy exposure to growing them to develop, so a new grower isn't going to experience it." (source)

"Actually, allergy might not even be the best word to describe the immune system reaction to oysters, which is much closer to a bad case of the flu than standard allergies." (source)

"I suggest a full face respirator with charcoal cartridges and an N95 attachment to go over the charcoal canisters. I bought mine from uline.com so I could go back to oyster growing" (source)
