Can you reuse jars that get contaminated?

[projectinfo]

I laugh at the overly clean procedures, new bands/lids.. really. Once you pc it, its STERILE. Whatever was in there is dead

Agreed, i have jars that are 9 years old. Just wash them in bleach. Buy new lids of your scared. But once you pressure cook them the mold spores burst. If everyone bought jars all the time that would be a tonn of wasted glass lol

Did You toss those or keep them ?

Pre-sterilized, self-healing injection port, filtered gas exchange port, and rye berries are, by many accounts, superior to other spawn media, such as BRF cakes.

OK, are these kits any good? They look like something I'd like to try. I have had mixed results with BRF. Either they are all good, or they all go bad with contaminates. I just threw out a bunch of jars. So, it's either buy new jars, or give this a try...

Ty

yes, you can re-use glass jars after contamination. just thoroughly clean them and
reuse. if you're pressure sterilizing, it should be good to go after it's been re-cooked.
if you're using atmospheric steam temperatures, you might consider using a 1000 ppm
bleach solution (1:100 dilution rate with 10% bleach)

they're ok, but way overpriced.

they're either all good or all bad because your sterilization technique is lacking.

I'm having no issues at all. I'd recommend them. I'm even kind of surprised I haven't contaminated it, as I'm always checking it.

5 bucks for a bag of compost and 5 bucks for a bag of grain with a vent and self-healing injection port is overpriced? Maybe compared to a bag of BRF. It's worth the lesser hassle, though. Recoup your losses by selling to friends.

Besides, you'll likely get more pins from the compost and grain than BRF cakes. More surface area.

I'm getting a fuckton of side pins. Gonna have to figure that part out. I'll take pics later.

Yep, I know. That's why I'd like to try these.

what's your elevation?

folks forget that the boiling point of water, and therefore the cook times necessary
to achieve true sterilization, are different at higher elevation. i moved from sea level
to 6000 feet, and had to extend PC times from 3 to 4.5 hours (for 4x 5lb protein
supplemented substrates) to compensate. for my low pressure steam sterilization,
cook temperatures dropped from 210 to 200 degrees and i had to extend from 14
hours at temperature to 24 hours at temperature.

I'm getting a fuckton of side pins. Gonna have to figure that part out. I'll take pics later.

your humidity is low or your air flow rate needs to be tinkered with. mushrooms require
evaporation to pin, so a fluctuation from 75-85% actually helps them pin more vigorously.
yours are pinning on the sides because there's a more humid micro-climate in that area.

sorry to say it, but to me, both brf and compost yields are garbage. i did supplemented
mycobags before retiring from cube growing, and pulled 5-6 dry oz per bag. i used coir,
horse poo, beet pulp, strawnet, and bran for my substrate. cubes LOVE beet pulp, but it
requires pressure sterilization and careful inoculation.

here's a picture from our farm, just so you can see i'm qualified when i give you advice.
these are pholiota adiposa, the chestnut mushroom. we run 4-500 blocks of edibles at
a time, i am to the point where i mak e more money with edibles than i ever could with cubes.

Compost = Horse poop, exotic zoo poop, coir, gypsum, and one more thing I forget. I think after this flush, I'm gonna redunk and flip it upside down. Pretty sure it's a humidity issue.

You sound kind of pompous and full of it. Not saying you are, but if I run a google image search, am I going to find that picture elsewhere?

 

[indianajones]

Maybe on my mushroom farm social media pages, I take lots of pictures from similar angles but only post one, so you might find the exact same one, or one from a split second later and slightly different angle. I also am a former admin on mycotopia.

Ah, gotcha. You'll have to forgive my skepticism, people talk a lot of shit. Any suggestions on increasing humidity, since misting and fanning is failing me? I also think I should flip the cake after this flush.

 

[indianajones]

An ultrasonic mister worked well for me before I got a high pressure misting system. Just remember that the mist is just micro floating water droplets, while humidity is water that has evaporated into the air. You need to either have enough air movement that the mist evaporates while still floating, or time it so mist lightly covers all surfaces and evaporates from the surfaces before the timer goes off and the cycle repeats. I think timing is harder and opt for air movement. Also try to scratch the mycelium enough to expose the material underneath. It works well if your cake has developed a dry stroma layer. It can be almost like leather.

The light is penetrating the container. If you were to black out to base of the container at the substrate line then your pins would have formed up top. Its likely that there was only so much energy devoted to pinning and the pins picked the best spot which turned out to be in the wall! They won't form in complete darkness versus an optional lighted location. Lol looks real cool though. Oh, and the shroomies will to to mush of they stay in there like that..

what's your elevation?

Yea, sea level here. I am still considering dropping the money and trying this bulk that's already sterilized. I have produced maybe 1/4 lb so far using BRF. I never thought I would ever be able to do it- I have dogs, and not the most sterile environment. I tried the oven door method- it worked once and failed once. Then I made a simple still air box- again it worked once and failed once. The last one failed, but the one before that was great- but I couldn't get much out of subsequent flushes.

So, yea, I'm still a newbie looking for a reliable method.

 

[ANC]

Just make a few 1" holes on the side and stuff them with aquarium filter wool
Also, line the outside of the tub with foil, about as deep as the cake, to prevent side pins.

 

[projectinfo]

Hey have ypu considered a flow hood for your sterile practice? Sounds like youve tried the other options and have some experience

 

[Tstat]

I'm having no issues at all. I'd recommend them. I'm even kind of surprised I haven't contaminated it, as I'm always checking it.

Hey man, can you tell me the process that you use? Or point me to a tek that outlines using this kit and this method?

I have some spores on the way and will be purchasing the bulk kit this weekend. I looked at their directions and it seems pretty straightforward, but you use a tub and not the bag?

Any help with this would be greatly appreciated!
