I started from one of the two LCs below which were both made using a spore print.


One drop of LC was placed on the plate below and allowed to grow out. There were no signs of contamination. Four wedges were cut indicated by the arrows.



Each wedge was transferred to a new plate and allowed to grow out.



A syringe was poked through the lid and the needle used to scrape up mycelium from the outer edge. Sterile water from the syringe was used to suck up the mycelium. The area circled on each plate is where mycelium was taken from.

Four syringes containing mycelium from each of the above plates.

Cliff hanger! What is your next move, to grain, direct to sub......inject yourself?! :)

Are those baby bottles with the nipples inverted for your LC? Genius!

Each syringe was used to create it's own LC.

The baby bottle method is a very old school tek.

Got a question.

I remember you prepared your bulk sous vide.

 

Just bought this guy to sterilize agar without having to babysit

 

it has a sous vide function, have you done sous vide casing pasteurization, if so how long and what temp?

Btw following the thread

 

Are you Pastywhyte from shroomery ?

I have not used it to pasteurize casing, only substrate.
For substrate I've been using 150*F for at least 4 hours.
I would thing if you are pasteurizing a casing you could use the same time/temp.



That thing looks like it has a pretty small capacity for substrate.

I am not Pastywhyte.

[Moby]

I generally sterilize everything, bulk and casing included.

My bulk is filled into 870ml jars of which 14 fit into the presto 23qt at a time.

For spawn I use the same or slightly smaller jars 730ml and just bulk 1 jar spawn to one jar bulk, no pasteurized bags.

 

The electric cooker was originally only thought to sterilize pre poured plates for SAB work, not for bulk prep, I want to check pasteurized casing and see if theres any difference.

 

Tried to pasteurize some casing jars in the dehydrator but one casing grew green (spawn and bulk were clean, was in a transparent tray) so I don't want to try that again.

 

The pot has a total volume of 6 liters (6,34qt) but a liquid maximum of 4 liters, three jars 2x 870ml and one 730ml fit in, thats enough casing to case the 2x 19qt and 2x 33qt monos that I bulked today.

 

Gonna go for the 150f for 6h to be on the safe side, cheers!

I put about 6-8 quarts of substrate in a food saver bag. I can fit 2 of these bags in the sous vide/cooler combo with a little room to spare.

I use an electric PC on the slow cook setting to hydrate my grains. I can do about 6 quarts in mine.

[Moby]

Thats cool, guess with bigger tubs I'd give that a try.

 

For spawn I use no soak, no boil millet, no pre cooking needed.

 

For stones tho I use rye that gets a long simmer, good idea to do the slow cook setting, gonna try that on my next stone run

Does that thing pressure cook?

Yes it does 1,8 bar = 26,1 PSI on a temperature of 241 fahrenheit.

Agar I do 30mins because of the lower temp, comes out clean.

Nice, I use my electric one for Agar and small glass jars (baby food). Then g2g those glass jars out.

I used mine for agar once but now I PC much bigger bottles of agar to pour.

[rockyfungus]

I used the electric one for hot sauce bottles of agar, haven't done that in years. The electric one is great for syringes, reusable plates, scalpels etc. Typically I prefer a full sized PC for a media bottle of agar.

I just did a load of LC in small small unmodified round PP containers, worked really well. Didn't break the chunk up though.

You said PP containers.
