you got a nice setup there. Don't get discouraged everyone gets contams or shit just doesnt go right. A lot of times when I have a lot of tubs going I'll have tubs turn green and thrown out before the first flush and it's also pissing me off LOL. Here's an example I hate when this s*** happens. What's confusing is I have the same exact box sitting right next to this one that's doing great. Same strain same spawn same substrate and one will do great one will turn green.

One thing i’ve yet to do is PC some cvg, usuing the same coco brick as you, spawning to bulk in the tubs and see what happens. What if it’s the coco bliss?
It kinda would make sense if there was trichoderma added to the shit for growing bud lol.
Had my absolute worse results with 180F water in the bucket tek. Like, way worse than boiling water.

First tub of JF that didn’t make it to the second flush out of about 30?
Cut the good side of the cake out put it in a new tub and it’s doing good.
This thing is outside. You never know

yucky. I should probably change my clothes now.

I won't even use any brand coco coir as a plant medium (let alone a fungi substrate) without pasteurizing it at the least with boiling water first (I'll even bake dried out coir in the oven if it sat around too long). Then rinse 2 more times because it's usually filthy, no matter how many times they claim to have washed it. Still has EC showing on the meter with slurry tests, but yeah I know its basically inert right?.. I don't even trust that the steam compressed 11kg bricks don't have a gnat egg latched on before the machine wraps it in plastic after cooling, lol. All the bricks shipped around the country are likely stored in the same warehouses as the pallets of organics, and if there's even a little hole in the wrap you can bet something probably crawled in :twisted:.

From trich, to bug eggs, to the air quality or factory conditions where the piles sit around outside.. Yeah I dunno..

It seems like the least you could do, considering you can't really use additives, pesticides, or cal hypo/bleach, or or anything else with mushroom substrates like we when using for plant mediums right?.

Instant pots can work good to pasteurize it with, if you need a small batch. Just leave it on the warming function and it will hold the perfect temps for hours.

Bucket tek is cool too, (coolers work best) but I would rather know that its actually holding temp for so many hours with a heating element, or come up with a cheap steamer barrel deal that can do whole bricks at a time, really cleaning the heck out of it, and also squeeze it to perfect field capacity every time after the cycle somehow. Juice out all the silty high EC coco water instead of leaving it and mixing as is..

You are overthinking and working with all the washing and doing slurry tests and stuff. You just need to figure out your field capacity for the type of substrate you are mixing(or type of coco used) and then pasteurize it all properly. That will kill anything that would cause a problem. Then get it into a clean workspace. At my last job I was processing 6-800 lbs of substrate a week. It was extremely rare that we had contam issues, let alone anything that could be traced back to the substrate. We put the substrate into turkey bags and squeezed all the air out before cooking them. Then when they were done cookng they went into sterilized totes and into the lab to get turned into grow tubs the next day when they were cool.

The only times we had definite substrate issues was when we switched to a new industrial-size cooker we made out of a 200 gallon stock tank. The first couple weeks took some figuring out to get the temp and duration for proper pasteurization on that amount of material.

I've known a few people who use the yellow and black totes from HD, and plumb steam into them from a simple pressure cooker through the blow-off port. They put a temp gauge into the top of the tote and monitor the temps and control the times.

i've got one grain bag that was injected quite a while ago and it seems to have stalled at maybe only 1/3 of the way. any suggestions of what i can do to get her going again? the only thing that changed was that the room temps have dropped since we are getting colder temps at night here.

I've seen people suggest massaging the bag to break up the clumps and redistribute the mycelium a bit. I'm thinking it's usually suggested for a bag that's around 1/2 colonized, though.
i think i started in near sept 10 and i did the break up thing after about a month. so now 2 weeks later it still hasn't progressed.

i gotta go out of town soon so i might just do the cvg and put it in the shoebox and see what happens

I wonder if you could hook up a huge boiler (or a gas powered steam generator? :eek:) to a couple free hot tubs, and do massive commercial forklift sized quantities at once, on a poor mans budget? ;)
wouldn't something like a steam table from a used restaurant supply place work?

Yep I'm sure that could work. I've also seen guys use the large plastic gaylord totes so they could move them with a forklift.

It could as long as it got hot enough. When we first started the farm I worked on we were using electric turkey cookers. We packed the substrate into turkey bags and had 3 of them that ran for a few hours a day multiple days a week to meet our needs. It took a couple of hours to get up to temp and then you had to hold temp to pasturize. It worked great for a while, but when we started expanding we needed something more efficient that we could fill all at once and run in one batch.

i did a few weeks of work at a hormel plant that had the huge walk-in pasteurizers for their chili. (more like dog food than chili but that's a different issue). when one of the cans exploded, that was the nastiest smell when they had to open them up.

Yep Big boy commercial mushroom farms also use systems like those.

I've got a buddy down in Cali that grows in big open beds. He pasturizes the whole conex unit all at once. He pumps steam in from a boiler.
