 Fruiting ABM blocks 
#16601658 - 07/27/12 09:03 PM (9 months, 22 days ago) |

Hello all,
I am at the point where I am trying to fruit my first rack of
Agaricus Blazei Muril blocks and I wanted to check a few things
with the team.
These are all in an indoor GH that has a Vicks running 7/24 pushing
fresh air into the bottom and a fogger (currently just running 15 mins
every four hours) that inputs in the top:
Here are photos of the block-tops:
These are two on the top shelf, two on the middle shelf, and one
on the bottom shelf.
These were birthed about two weeks ago.
I find that, even though it has been explained to me that humid air
rises, the blocks are drier as one moves up the GH.
It has been around 80 F and not less than 68 F during the nights where I am lately.
Questions:
Do I need to scrape off and re-case blocks number one and two?
(they are in order above)
What is the typical wait time before seeing pins with this species?
Does this species deal with being drenched? (occasionally vs. more consistently?)
Does this species like or need to dry out, a la Shitake?
I have more blocks coming up. Does this species like SFGC? I could
try on or more in a SGFC too. (i.e. are they FAE hogs like Oysters?)
Any comments appreciated.
Take care,
JD

What did you use as a substrate?
Did you heat the casing?

Right. I should have added that.
These are highly composted hpoo subs, together with cactus soil (1, 2, and 3)
and 50/50 peat+verm (4 and 6)casing soils.
The subs were sterilized in filter patch sacks.
The cactus soil was just moistened where the 50/50 was pasteurized.
This species ripped through the subs, in every case.

I hear fruitbodies will only form on non heated casings, but I could be wrong.
I also think you need cooler temps (68°f-75°f) to initiate pinning.

I have heard of the live casing soils issue, but thought that Blazei
like it warmer.
Hmmmmm....

You are welcome.
This is the first time that I have grown ABM...my first Agaricus actually,
so I am happy to open the topic to discussion.
I have more blocks colonizing and will be just burying one outside
as well. We will see.
Take care,
JD
P.S. I am about to open a similar thread on Maitake. As it turns out,
I am getting my first blocks of that species ready to fruit as well.
...but I want to re-search the topic before I ask for data that has
already been posted.

As to temps, I found this on the Unicorn site:
Quote:
The mycelia can grow at a temperature range of 50-98.6°F, and the suitable
temperature is 73.4-80.6°F. The fruit body can occur at a temperature range of
62.6-91.4°F, and the suitable temperature is 68-77°F.
So, it looks like my temps are pretty optimal....

Hey JD,
I'm right behind you. I cased 5 bags of these yesterday! I used 2-inches unpasteurized peat moss, garden gypsum, and vermiculite, as per Stamets TMC. I put this in an outdoor greenhouse with humidifier and fan for FAE (greenhouse plastic door is left partially open). Temps have been warm, so I haven't added a heater. And I'm an Agaricus virgin too!
Regards,
Terry

Right on Terry. I am glad that you are here.
I am going to bury a block, as my local weather is pretty good for them.
I am having to try everything, so some failure is expected.
I am happy to have a place for us to collaborate.

i feel the bromance in this thread lol
glad you guys are giving ABM a try. just transferring some to petri dishes from cold storage today. will be taking notes from this thread.

Check our join dates Mad.....Terry and I have been working together
since we started. He is mad tech where I am relatively ghetto, but
this may change if I get working and make some dough. :0)

Mine were fast, too. I uses sterilized filter patch bags of field-aged hpoo also, but with 10% vermiculite and 5% gypsum. I noc'd these on 6/30, and kind of forgot about them. Then I happened to look on the shelf the other day, and they were solid and white! In GGMM, Stamets says colonization takes twice as long if using sawdust.
Stamets also says they need 70-75 F for primordia formation. I figure they will get this at night in my New England climate.
I just noticed:
You've got 5 bags too! I intended to make 6, but did the inoculation at the end of a long lab session, and screwed up by putting something else in the 6th hpoo bag.

We have fruits!!!
They are emerging from the sides of the bags.
Here's the big one, 9 cm in diameter!
And the smaller one, 6 cm in diameter.

We have a winner! Cool beans Terry.
I read that you want to harvest them before the veil breaks. Did you
see this too? If so, then those are ready.
I want an "eat report" shortly. :0)
I am coming to the conclusion that I need to scrape and replace my
casing layers, at least on a few of my blocks.
I did the traditional "wait until you see mycelium poking through the casing"
approach and now I am thinking that I should have gone right into
fruiting conditions.
Great work!

Thanks, JD. They appeared to have fruited so fast that I missed the veil intact stage. I wasn't expecting them to start so soon. I'd noticed a bulge on the side of one bag, but didn't know a giant mushroom was going to pop right out. But this was only 2 out of 5 bags. I just harvested them, and the pair weigh 9 ounces together -- more than half a pound!
I will provide a report on the flavor, probably tonight. I am going to slice them, saute, and put in a giant omelet that will be dinner for me and wife.

Nice weight!
I will report on whether the re-casing helps my more solidified blocks.
JD
P.S. How long after casing did you go to fruiting conditions? How long
after entering fruiting conditions did you get those meaties?

I cased only 3 days ago! For whatever reason, these two guys decided to get a head start before casing. I put all the bags into fruiting conditions immediately after casing, because according to Stamets' growth parameters, there was a lot of overlap in both temperature and humidity for primordia formation and fruiting. But I expect my other bags to greatly lag behind these very early ones. These two might not have been a test of the casing at all.
