Mycelium fight. Jar was fucked up black all over. Put it in a bag and was going to toss it. Forgot about it and discovered a week later that the Mycelium had covered the whole cake. Gave it a go and here i am. Pictures taken an hour ago:

I confess I may have gotten a little over eager with agar....

I've got 6 differet prints germinating. Cambodian Gold, PE6, RustyWhyte, RedBoy, Mazapatec, and AA+. I have three monotubs.. I think I'll end up spawning the fastest three and further isolating and/or g2g the other 3 to buy time.

Cambodian Gold is gonna be the first to a tub, its colonizing in WBS jars now


I started shading in blobs of sharpie on the bottom of my petris where I want to isolate. I draw the portion I want to isolate outside my SAB so I can make a better cut when working inside the SAB. Worked well for me, any thoughts?

Also, quick question: I know that a strain is two individual spores germinating, so what is the correct terminology for the variety of names of mushrooms you see when buying/trading prints? e.g. Cambodian, PE, Puerto Rican, RedBoy. Some seem to identify the geographic location of the shroom while others obviously do not. Just wondering so I can stop calling them strains when I know thats not what they are lol

lol alright, makes sense. Variety always just seemed like a layman's term to me, I appreciate the answer anyways :cheers:

I suppose you can call it race too. there are many races of human, yet we are all the same species. just like a cube is a cube, but they all come from different places

Lol, just posted the same thing in the agar thread about the sharpie... I also like to write the number of transfers in reverse so it shows proper through the plate when working:



I confess, I'm a very patient person, but I can't get away from working for someone else fast enough... baby steps, but damn it Jim!

I do marks kinda similar. If i notice a satelite or some bacteria, I circle the area on the lid so I remember where it is when the myc covers it. I load with the good sector(s) I want facing me in the sab so it doesn't matter that the marks are gone with the lid in most cases.

I like you're idea for coloring the bottoms, would be great for a plate with heavy bacteria through it. Little light and the plate on top a few empty plates should light right up.

Cool man! I'm always down to change my views when confronted with good information. Glad you posted :smile:. That casting video was really cool, I dig that.

I'll be honest, I fucking hated materials science, I understood most of it, just didn't care for the class. But humor me here:

For the softest common alloy of aluminum (annealed, which is likely what happened to the bottom of his, when overheated) the maximum yield strength (the point before which all deformations will be elastic, right?) is no more than 83 MPa (12,000 psi). For a safety margin let's say safe operating at stresses of 3,000 psi. Now that's the pressure exerted on the vessel as if it were being stretched from either end. As in if we had two vectors with half the force at opposite ends of the material. In this system we have many other vectors from the structure of the material, so it's more complex, but I believe the stress felt by the material would still be less than the pressure of the pressure vessel, correct? Not sure here.

With fatigue taken into account lets say that's a reduction to 33% of it's former strength (10^9 cycles). Then we're at 1,000 psi neglecting the physics of the system in a conservative way. Still seems like a heck of a margin. I'm likely way off base here, just would like to understand better.

Anyway, the ORLY was actually serious, (couldn't you tell? :wink:) I was totally open to an explanation, just glad someone offered one. Seems like all the accidents from pressure cookers stem from improper use of failure of something other than the metal itself.




i knew your were awesome, juniperus. i'm afraid the reasoning here isn't quite right, tho. material strength is measured in units of pressure, this is true. force per area. psi in the us, and Pa (pascals, Newtons per square meter) everywhere else in the universe. however, this is not the same thing as the pressure inside the vessel. quick and dirty, 15psi inside a cylindrical vessel of quarter inch wall thickness and six inch radius results in around 360 psi principal tensile stress, and 90psi max shear stress. still plenty small compared to the strength of the material.

except no. aluminum pots are cast. reaching back to matsci, cast materials have vastly more defects in their crystal structure, which is where cracks come from, and which are all made worse when the material is bent. this is why high strength parts are machined from solid billet aluminum. a severely bent aluminum casting usually doesn't survive being bent back. it just snaps. assuming the description of the treatment of that vessel is accurate, there is literally no way of knowing or predicting how and when that pot would fail, if ever. it can only be tested, which is exactly what the man is doing every time he runs a cycle. each time it's run, that paperclip is bent back and forth one time. were it to finally break, i would predict a burst mode due to brittle failure of the material, rather than a ductile failure resulting in a crack which would stop once pressure dropped enough. burst mode with 15psi two phase water mix is no bueno. there's a fuck of a lot of energy in there, more or less depending on how much liquid water were in the pot when it blew.

nevertheless, the crux of the argument isn't the knowability of the failure of the pot. it's the risk/reward of not demoting the pot to grain prep only, rather than using as a sterilizer. i suppose a counter argument to the effect of, "we're felons for fun. we live on the edge," could be easily made. this hobby naturally develops the sense of risk tolerance. best i can say there is, i could be wrong. before the great ballooning, that pot had such material strength to probably never fail under pressure. afterward, however, catastrophic failure might well be possible if not likely. to my way of thinking, if there's one chance in a thousand, it's not worth the risk.

i confess. i now want to find me an old aluminum pressure cooker and blow it up. you know. for science.

Hell yeah! Awesome. Great response. As I suspected, I knew there were some things I was missing. Curious how you calculated the principle tensile stress of the vessel, I'd be interested in the physics of that if you could link anything about it. I suppose that takes into account the supportive nature of the cylindrical shape? It would make sense that the bottom is thicker, in that context.

Also, yeah all my reasoning was considering a completely defect-free material which is far from the likely case. Figures, crystalline defects was one of the parts I fucked up on in materials science :lol:.

I agree, I would probably not use it at higher pressures, personally. I enjoyed the discussion though :smile:

I confess, I learn a lot on here, and not just about mycology and cultivation :mushroom2:

Also, please pressurize a PC that you've entirely welded shut to the point of rupture, and document/record the results, that would be awesome.
