King Oyster Ready-to-Fruit 3lb Block

Description

Pleurotus eryngii

This species of oyster is prized for its thick stems which are a great meat substitute (hence the name “Kings”). Kings are best when top fruited and require relatively cold temps. They tend to produce a single large flush, but can produce a second flush. A great mushroom for those trying to expand their culinary library options.

Fruits best between 55-65°F.
A top fruiting species.

Instructions for use:

This information is specific to King Oyster.

1. Check your block upon arrival to make sure there are no tears or signs of mold from shipping. If the block has broken into pieces during shipping, gently press the block together and let sit 4-7 days undisturbed (ideally in the dark) before moving to step 2.
2. Cut open the bag as close to the seal as possible. Fill the bag with air and gently fold over the top a single time and use 1 paperclip (or similar) in the center to keep the bag closed and relatively inflated with air.
3. Place the Ready-to-Fruit block in an area of your home that is between 55-65°F (ideally 55-60°F). Check the bag daily for baby mushroom pins growing at the top of the bag. See example below for pinset.
4. Fold the top of the bag down (or cut it) to ~2 inches from the top of the mushroom pins.
5. Place the Ready-to-Fruit block in the most humid part of your home (not in direct sunlight) or in a grow chamber or grow tent. The kitchen is a good household place in lieu of a dedicated fruiting chamber (as long as it is cold enough). King Oyster fruits best between 55-65°F.
   Search online for easy to make fruiting chambers: monotubs, shot gun fruiting chambers (SGFCs) and tents with foggers/humidifiers are all great options and will likely increase success in fruiting and producing healthy fruits. Even a clear trash bag with plenty of holes can be used to increase humidity! King Oysters are prized for their thick meaty stems produced when they have less air exchange, more air exchange will lead to larger caps which are still delicious.
6. 2X daily (or more if your environment is dry) spritz the plastic sides and mushrooms with filtered/distilled water. Try to use a fine spray and not leave pools of water on the mushrooms. If they are drying out spray more than 2X per day.
7. Continue to mist the fruits and plastic while they grow. King Oysters are usually ready to harvest 4-7 days after pins form and the top is folded/cut and should be harvested before the caps flatten out or become concave for tastiest results.
8. Cut the mushroom cluster from the block and enjoy for your next meal! Checkout those King Oyster Scallops MMM made in the photo below.
9. Soak the block in fresh, cold, distilled/filtered water for 1-6 hours while inside the bag (pour into the opening) and then drain.
10. Put block back into fruiting conditions, you should get at least 1 more “flush” of mushrooms from the block.

*CAUTIONS AND CONSIDERATIONS:

IF YOU PLAN ON CONSUMING YOUR HOME-GROWN MUSHROOMS MAKE SURE TO COOK THEM THOROUGHLY. IF IT IS YOUR FIRST TIME EATING THIS SPECIES, IT IS BEST TO START WITH A SMALL AMOUNT TO SEE HOW YOUR BODY RESPONDS!

MUSHROOMS PRODUCE SPORES AS THEY DEVELOP. THIS IS A NATURAL MEANS OF REPRODUCTION FOR THE FUNGUS. THEY USUALLY APPEAR AS A DUSTY SURFACE ON YOUR GROW KIT BENEATH THE MUSHROOM CAPS. PEOPLE WITH ALLERGIES OR COMPROMISED IMMUNE SYSTEMS MAY WANT TO CONSIDER PUTTING FRUITING MUSHROOM KITS OUTDOORS OR IN A WELL-VENTILATED AREA AS AIRBORNE SPORES SOMETIMES CAUSE RESPIRATORY IRRITATION. SPORES MAY ALSO CAUSE IRRITATION FOR SOME NON-ALLERGIC OR IMMUNE COMPROMISED MUSHROOM GROWERS, THOUGH THIS IS RARE. HARVESTING MUSHROOMS WHILE STILL IN THEIR YOUNGER GROWTH STAGES WILL REDUCE THE OVERALL SPORE LOAD.
