1st attempt at agar!

potato starch / dex / agar / yeast
PC'd for 30mins 15psi
PE #6 spores
day 10.





how does it look to everyone? im not sure if those pink dots are lipstick mold or not. not sure if there is to much moisture in there.
the second last photo looks like it has a contaminate that needs to be removed.

I`d send these to hell. That`s bacteria and mold. Looks dangerous. What was the colour like before inoculation? You have to improve sterile techniques.

The color before inoculation for the agar is that deep purple color.
I am starting to wonder if the spore syringe i have is no good. This is the second batch from the same Spore Syringe. First one batch came out with lots of pink dots as well, didnt make it as far as these current ones. I threw them out before anything white appeared.
I have read a bunch of bodhi's posts. My agar was done similar to Pastywhyte's Easy Agar Tek different color and PDA + yeast. This was pressure cooked @15psi for 30min.
I have made a SAB with 3" holes with gloves attached and put this SAB in my small den (4x8) room. Before I used my SAB, I would go in and spray the air down and wiped the desk, SAB, PC, lighter, spore syringe etc. Everything was wiped down with lysol wipes or 75% iso. Sprayed myself before i would enter the room after i cleaned it up as well and had gloves on along with a mask. All of this was done before inoculating.

Perhaps we have the answer now. I would advice to remove the attached gloves, that`s outdated, but can work perfect if you know exactly what you`re doing, let`s say for G2G, as you don`t have to move out, once loaded your SAB. Air pressure may change due to your movements in the gloves, and forces airflow in. A SAB never has gloves attached, that`s a glove box, and it totally destroys the purpose of a SAB.
I remember also being a bit paranoid, as i started with a SAB. Most important are your evenly movements, don`t overdo with too much sanitizers. Close doors and windows, spray room down a bit, clean the working surface, perhaps a bit soapy water to the SAB and you`re good to go.

Its probably the syringe.

Of course that`s also in the game.

It looks like you can grab something from the 6 o clock area of plate 3
Using purple agar always looks interesting because most of the time, the mycelium will eat the blue dye and leave behind the red. This is what is happening in your case

^^^ This, and those plates are loaded with bacteria. Next time just use a DROP. If you're using a syringe, consider wrapping some qtips in foil and throwing them in a jar to sterilize for like 20min @15psi to make some makeshift swabs to put a little solution on to swab the plate. All that spore solution makes for a bacterial mess (all syringes have some contamination so more solution introduces more contaminants). You can also make an inoculation loop from the metallic inside a twist tie for garbage bags to hold a drop of solution.

Yeah, could be worth a try, if you really need the plates. I´d just start a new batch, ideally with a spore print.

Yeah, I just noticed those pics were posted 2 days ago, so it is likely not salvageable anymore anyway

Looks like it has bacteria even on the part the myc hasnt touched yet
Id toss all that
@op did you do any control plates? You should. Thatll help you start your debugging. If those are good, try streaking the plates like the gif in my sig (explained in agar guide)
Even if the syringe is dirty, you should be able to get clean myc pretty easy by using serial streaking. Just focus on your technique

Also... opening them to get a pic of them... not a good idea.

thanks for the help everyone.
I already threw everything out and I've already started a new set of agar dishes. I'm going to try the streaking on the dish this time. I have another spore syringe from this supplier, i hope its my process. I know where i need to make corrections in my process. Hopefully its enough to make things work.
I had to much moisture in the agar to begin with, in combination with to much from the spore syringe.
also what does he mean by control plates?

Take a sterile plate and dont inoculate it or open it. Take another plate and open it in your sab , then close it without inoculating
Then procede with inoculation of a 3rd plate
Those 2 control plates will give you a good idea which point things are going sideways
