    #21965571 - 07/19/15 02:49 PM (8 years, 6 months ago)

i recently did 10 jars

i had problems in the past with contams so i did a lil research i baked the verm and brown rice flour for 20 min 450f and used purified water(reveres osmosis) also i super grinded the verm layer on top. is that over kill or are we trying to overkill

You can easily boil the jars in a pot with a lid. You don't NEED a pc for pf tek but I've gotten away with boiling pf tek jars every time without contams. And don't grind the verm layer just put normal dry verm and you are good to go.

well in that case everything is a go but i did need to grind the verm on the top layer itll act as a better filter and coat thoroughly the entire top layer of the substrate

now the only way they can contam is from inoculation

or if they get smashed into a a thousand pieces :shrug:

Use an uncontaminated spore syringe. That's the most common reason for contamination with PF tek. Baking the verm and BRF and using purified water isn't going to help anything.

it does it kills any mold spores that would be laying dormant inside

now ik as soon as they got out of the oven they were for sure coated with more spores but i like to think of it as gross decontamination

Trust me, mold spores are not going to survive 90 minutes of steam sterilization even without pressure. If you're getting mold in your jars it's getting in them after you sterilize.

A PC will come in handy if you move on to whole grains. PF tek can be done without one though.

I did my first with just a stock pot lined with lids to space the jars from the bottom. It worked out fine, I did however get contams but it was due to my shoddy sterile technique. It seems if your spore syringe is 'clean' and hasn't shown any reason for failure, then it would be sterile technique. I believe my failure came from working in open air in a high spore load area. Make a SAB, and sterilize the needle with a torch in between each jar. The SAB took my failure rate from 50% to 5% alone.

^  Bacteria are the only thing that could potentially survive the 90 minute steaming.  Bad syringe, bad technique, or failure to follow teks are the main reasons for failure.

You don't need a PC for PF tek, and infact I'd encourage you not to get one.  If you're ever making so many cakes that you need a PC, you shouldn't be making cakes anymore.


--------------------


I spawned some popcorn casings and had double-overlay cause I didn't put enough hydrogen peroxide in my automated aquarium mister.  I only got one mushroom so I cut off the head part where the seeds fall from and put it in a jar of LC and sprayed it all over a tin of PF cakes I made with gravel, cardboard, and bisquick in my microwave.  I think it will be good cause B+ is so potent.
Triggered yet?

Only a square would say "a cube is a cube."


No, this does not look right...

I made this mistake when I was in a hurry with my WBS jars, only one has visible growth after 2 weeks : / I would highly suggest inoculating against the glass/plastic/whatever container you use with MS.

The tek and the instructions in the pf tek are there for a reason. People get good results when they follow the tek.
