Detailed Blue Oyster Mushroom Growing Instructions:

Start by selecting a clean spot in your kitchen with indirect natural light and a stable temperature between 60 and 70 degrees Fahrenheit. Unbox your mushroom grow kit and locate the marked fruiting area on the bag. When you’re ready to begin, use a clean knife to make a slice  directly where it’s marked. This slice creates an opening for the mushrooms to grow from.

Place a small clean towel, folded, in the bottom of your casserole dish. Pour a small amount of clean water into the dish so the towel becomes damp but not submerged. Set the grow kit upright in the dish, directly on top of the damp towel, with the sliced area facing out or slightly upward to allow for airflow and mushroom formation. There’s no need to open the top of the bag or disturb the contents inside.

Use a clean spray bottle filled with water to mist around the sliced area two to three times a day. Spray the air surrounding the slice and the inner sides of the casserole dish to maintain humidity, but do not spray the mushroom itself or the exposed substrate directly. Moisture sitting on the mushroom or substrate surface can lead to rot or contamination. The goal is to raise ambient humidity, not soak the kit.

To help trap humidity, drape a clean, damp towel loosely over the entire setup like a tent. Keep the towel slightly elevated so it doesn’t rest against the sliced area. You can re-wet the towel once a day by misting it or briefly soaking and wringing it out so it stays lightly damp. The towel will act as a simple humidity dome.

Within a few days, you should notice primordia beginning to form at the slice. These are the mushroom pins and signal the start of fruiting. Continue misting the air around the kit and keeping the towel damp. Avoid spraying directly on the mushroom as it grows. If the environment stays humid and well-ventilated, the mushroom will mature within seven to ten days.

Harvest the when fully mature but preferably before the mushrooms release spores. Use a clean knife to cut the mushroom off at the base, as close to the grow block as possible. After harvesting, tape over the opening where the mushrooms grew from and make a new slice at another location on the bag and repeat the process.

Once the block stops producing, you can compost it or bury it under wood chips outside to potentially yield mushrooms in the future.

Now for troubleshooting.

If no mushrooms appear after two weeks, the most common cause is low humidity or poor airflow. Try increasing how often you mist the air around the kit and briefly lift the towel for few minutes each day to refresh the air. Make sure the kit is not kept in a very dry, cold, or hot location.

If pins form and then dry out or stop growing, humidity is too low. Mist more frequently and keep the towel slightly wetter. You can also loosely tent the entire dish with a large clear container or bag with holes to trap more humidity.

If the mushrooms look yellow it could be a lack of humidity or too much humidity. If they grow very slowly, or develop a fuzzy texture, there may not be enough air circulation and too much humidity.

If you see green, black, or pink mold, that’s a sign of contamination. This may be due to direct spraying or poor air exchange. Do not spray the mushroom or substrate surface. Remove any small, contaminated areas with a clean knife. If the contamination spreads, dispose of the block.

If your kitchen air is especially dry, you can place the whole dish setup inside a larger clear bin or tote, with the lid propped open slightly for air. This will help trap moisture without suffocating the kit.
