killer! hows the taste?

so did you just put em in the tub without the lid on and keep perlite and mist? i can't for the life of me get these things to fruit in the tropicaire setup...

the pinks look like they are recovering well after a dunk but its newspaper and not straw.

They taste good if picked early and used right
away. They don't store well. After 24 hours in
the fridge they start getting squishy. By 48 hours
they are garbage.

The immature ones taste better. Once they
mature & start dropping spores they get tough.
The clump pictured in my previous post is
exactly perfect size/age to pick for best taste.

You can still use the mature ones but they need
a bit more cooking to soften up. The short stems
are tough regardless of age. I chop the stems
into pieces and start cooking them first for a few
minutes before adding in the caps.


These were fruited in a 64 qt sterlite tub. The
tub has about 2 inches of perlite on the bottom.
That plus misting 2 times per day keeps the
humidity up.

There are no air vents in this tub. I keep the lid
on but not clamped on. Lid just sits on top, slid to
the left about 1 inch. That leaves 1 inch on the
short side open for air exchange.

The tub seems ok for fruiting but takes up too
much time & fussing to maintain humidity levels.
If I forget to mist, they start to dry out fast.

I bought a cheap 4 tier mini-greenhouse thing for
future grows. When I get time & money I'll hook
up a humidifier, fan & timers. I saw some nice
setups here on message boards that look like
they could make some of the maintenance
chores easier.


Started seeing some mold growing around the
corners of these bags. I think that's a signal to
give up on these and move on.

Discarded contents of bags in a pile outside in the
woods. Threw some straw, wood chips and
chopped leaves on the pile. I'll check back on this
pile next spring to see if anything develops.
Who knows, I might find a surprise.

I learned a lot on this grow. Thanks everyone for
all the encouragement, help and suggestions.

the pinks lasted a good week in the fridge for me.

check out this thread. you could do a fogger setup.

im currently trying a single tub grow with the pinks.

not real sure why when i was using the tropicaire setup they stalled out. i even fanned as well. but so far in the single tubs they look good. pins are forming on dung/coir.

I've also found that using the plastic grocery bag method that i only get one really great flush, then one ok flush before the life of the bag is through. Considering that commercial growers normally only produce one flush from their oyster substrate logs before tossing, i'm pretty ok with that. I love to think of patches of oysters popping up all over the city dump from my tossed bags.

I also prefer the way oysters taste when grown on newspaper as opposed to straw, but YMMV. I store mine in a paper bag placed inside of a plastic bag. They can last a week or more that way, although if you're going to keep them long try storing them upside down so they don't drop spores all over the inside of the bag.

I like to cut off the aborts and tough parts of the stems and dry them on the counter, then add them to soup stock. Drying improves/concentrates the umami flavor.

Sweet fogger setup Eaty, thanks for the link.

Thanks for the paper bag tip Tasty, I'll have to
try that to see if it can help preserve these pearl
oysters for longer than a couple days. I've been
keeping them in the fridge in lightweight plastic
containers that have vent holes. The containers
are similar to what you might get with a package
of strawberries. It hasn't been working well, any
more than 2 days in the fridge and the oysters
are no good. I'll try paper bags next time and see
if that helps.

Starting Again...

Found a couple overlooked wbs jars of colonized
oysters. These 2 jars have been fully colonized
since July and left sitting in a cool, dark place.
The jars looked pretty good, nice and white.
There was some stringy white myc growth in the
airspace above the seed, apparently trying to
escape the jar.

Pasteurized some straw and spawned these 2
quart jars into (3), 1 gallon ziplock bags. So far,
the results have been disappointing for two

First, within a few days of spawning, all the myc
seemed to disappear from around the seed
kernels. Not sure why this happened but it could
be from the age of the colonized spawn. Or
maybe it was to much lime in the water used to
soak the straw, prior to pasteurizing the straw.
Not sure why.

Luckily, some life was left in the spawn and some
colonizing has begun in a couple spots. Here are
photos of two of the bags...

Note, no growth surrounding the seeds.

Colonization has progressed slower than I would
have expected. Its been slow but steady. Six
weeks into colonizing and they are now only a
little more than 1/2 colonized.

Second problem...
One of the bags developed a yellow or amber
area of discoloration. I think this is some kind
of bacteria contamination. The area is directly
under one of the air vent slits in the bag.
Suspect contamination entered air vent slit.

This contaminated area appeared right in the way
of the expanding myc a few days ago. The fluffy
white myc has now surrounded this area. In the
photo below, you can see this oval shaped area
towards the upper right corner. The discolored
stripes along the left edge are just bad lighting
on folds in the bag that tricked the camera.
Those stripes don't exist except in this shot.

with close up shot of problem area

I probably should just pitch this bag. But, as an
experiment, and because I don't know what I am
doing, I just left this bag to continue on and will
watch to see what happens.

OK, round two continues...

Checked in incubator this morning. Sweet smell
of oyster mushrooms hit me in the nose. Found
all 3 bags have fully colonized.

Bag 1

This is the bag that had the weird yellow color
near air vent.

091121 Pearl1 - 3.jpg

091121 Pearl1 - 6.jpg

That problem seems to have made no difference.
You can see new grow sprouting from the suspect
air vent.

Bag 2
Fully colonized, no problems, sending this one
into fruiting tub. Nothing remarkable, no photo.

Bag 3

Now this bag has developed a bad spot near
air vent.

091121 Pearl3  - 9.jpg

It also has pale yellow discoloration on bottom.

091121 Pearl3  - 10.jpg

Suspect problems caused by higher incubation
temps of 76-80*F. Or maybe it was the aged
spawn. Don't know.

I guess I will let bag 3 run for awhile and see where it goes.
Not sure if any fruits should be eaten from this.

Out of 3 bags, one is doing well.

Bag 1, shown above, has started fruiting.
Bag 2, has signs of life.
Bag 3, the yellow one, isn't going anywhere.

Bag 1 went first and harvested a couple days ago...

the yellow stuff is fairly normal. it's a contaminate, but nothing to really worry about. very common in nature.
