A little trickier to grow due to its love for chilly cold temperatures,
be sure to pay attention to the intructions below or your kit may not produce any mushrooms at all!
Your Grow Kit comes with a Recommended Bag Cut Date.
You can find it on the top flap of your box.
Before this date, all you have to do is sit the bag upright inside of the box with the white filter patch up so that it can breathe and watch the mycelium colonize the bag.
During this time it will be normal to observe some yellow / orange liquids (aka metabolites). They are just the products of digestion. However, excessive amounts could mean a some sort of contamination. Be sure to watch for signs of contamination such as black or green molds.
If your grow kit is contaminated at this point we will be happy to replace it for you.
If you have any questions, feel free to reach out to us.
Occasionally your grow kit will not be ready by the recommended bag cut date. You will be able to tell if this is the case because a significant portion of the substrate is not yet colonized.
If this is the case then just wait a few more days.
Its your bag cut day and its time to trigger the growth of baby mushrooms! (pins)
The Black Pearl King will not produce mushrooms unless it senses that winter is coming!
First lets put the grow kit somewhere clean and cold! Ideally 60-65 deg F.
But so long as it reaches lows of 33 – 67 deg F for a significant part of the day, you should be ok with highs of 72 deg F.
Avoid direct sunlight and keep away from dry direct air flow.
A cold kitchen counter or garage is usually suitable. ( You can even do the first 3-5 days inside your refrigerator! )
Lay the grow bag back in the box and with a clean knife cut the bag along the mark on the bag (Either an X or a slit). Its ok to cut a little into the actual substrate.
Fill up the spray bottle with clean water and spray the area where you cut as well as the entire inside of the box. Its important to maintain near 100% relative humidity during this time to encourage the formation of baby mushrooms.
If you have a home humidifier, place it near by.
If you are in a dry climate, use the provided biodegradable bag to create a humidity tent,
You can flip the box flaps up and place the bag over it to increase humidity. HOWEVER, be sure to poke ALOT of holes in it for proper ventilation.
Keep misting 3-5+ times a day for 3-5 days until you see baby mushroom blobs begin to form.
If you see blobs form far away from your slit, you can cut around them to release them.
Once the baby mushrooms are about 1/2 inch tall, do not spray them directly anymore. Instead, spray around them. But still 3 – 5+ times a day.
The goal is to maintain 75 -95 % relative humidity until it is time to harvest.
Once the mushrooms are 1 inch tall, you can remove the humidity tent and lower the box flaps a little to promote more fresh air exchange.
If you notice that the mushrooms start growing very long stems, try to increase fresh air while still maintaining high humidity.
Watch your mushroom grow! They may double in size every day!
Remember, the dryer your climate, the more you’ll need to spray, it is not uncommon to have to spray 10+ times a day,
but becareful to find a balance, soaking wet can encourage bacteria growth!
Finally its time to harvest!
It is best to harvest before the edges of the mushroom caps flip completely upwards and the mushrooms begin to release their spores.
Black Pearl King Oysters, are typically ready to harvest 9-18 days after slicing the bag open, depending on temperatures.
Mushrooms rapidly deteriorate after they release their spores, and spores can also be a mild to severe respiratory irritant so, please be mindful and try to harvest on time.
You can harvest your Black Pearl King Oysters by grabbing the mushroom cluster close to its base and twisting while lifting!
A typical yield for your first harvest will be 1 – 2.5 lbs.
You might find a bit of substrate attached to the base of your mushrooms, you can just chop that off.
The stems of the Black Pearl King are delicious , so be sure not to throw them away!
DO NOT EAT THEM RAW! They do not taste as good, are not as nutritious and can make you sick! So be sure to cook them thoroughly!
We like to simply sauté them on high heat with a bit of oil until browned on both sides. Add salt at the end.
Black Pearl Kings are best stored in a paper bag in the refrigerator where they will remain fresh for 7-14 days.
If you did a good job at keeping clean and your grow kit is not entirely covered by mold you can likely get more than one harvest from your block!
However, each subsequent harvest will yield less mushrooms and is more likely to become contaminated.
To do this, start by plucking off all remaining pieces of old mushroom and taping over the cut plastic. Be sure to seal it well otherwise little mushrooms will sneak out.
Flip the block over to a new uncut spot, and repeat the fruiting process from step 2.
It might take a few days longer than previously so be patient! Typical yields for 2nd harvests are 1/4 lb – 1 lb, 3rd harvests are very unlikely.
Even still, the usefulness of your mushroom substrate block isnt over yet!
Remove the bag, break up the block and add it to your garden.
“Spent Mushroom Substrate” is known as an EXCELLENT compost and soil amendment. It can really help your garden grow!
You can also bury the block whole and your garden might even sprout some extra mushrooms!
