I'm trying to say that steamed grains don't work very well for gourmets.
Others in this thread are using steamed grains into coir for cubes with success.

some of those do look slightly bacterial. does anyone have a good link to one of those Chinese autoclaves?
Those aren't the best example of what we're doing here tbh. It's the ones we fruited last and some are also not done colonizing.

Molds and their spores are killed/neutralized at relatively low temperatures, 135-155f. Bacterial endospore can survive much higher temperatures and are MOSTLY neutralized via atmospheric steaming.
I would guess that the species you are growing runs over bacteria well and you end substrate has almost no nutrition in it. I mean, you could use hot tap water on coir and be OK. So, what works for you ends up being a time bomb for the less aggressive gourmet strains being grown on rich substrates.
For anyone trying to run and scale a business, 36 hour cooks are a huge cost in utilities and time for your equipment to be tied up. I can get 3 sterilization cycles through a 150L per work day. That said, it's your business and life, make of it what you will.
I run my sterilizer 1x a week usually. My power consumption costs mostly come from running heaters to keep my fruiting room in the 70s. I would love an autoclave but theyre not that cheap and what i have is working just fine. Shits rough right now. No lack of product... definitely a lack of sales though. If that changes we will probably upgrade at some point.

I'm glad I got out of large scale cube production and into the gourmet side of things when I did. I have friends that are still in it and no matter what part of the country it's tough. I'm hearing a lot of low demand and a race to the bottom on pricing for bulk loads. I'm not doing all that work and taking all that risk for 350 to 400 a lb! Fuck that. We ran hard for years at 700 a lb and it made sense. By the time you factor in your labor, risk, and overhead nothing under 500 makes sense to me
Greedy weed growers in California switching over to huge mushroom grows and flooding the market. It's a race to the bottom

no boil works the same with gourmet.. however i don't grow nearly as many gourmet as i do actives, but i am always growing gourmet.
for the guys doing no boil.. i strongly suggest you soak the grain in the water and bag you are about to sterilize with for 12 - 16 hours prior. Right before you sterilize, shake the container to distribute the wet grains evenly. -try this out, i promise you won't have 'dry spots' / or hidden bacteria / ect.
i have ran thousands of bags with no boil.

Sorry if I offtopic but I'm really interested in this as I'm thinking about buying an autoclave. You can do 3 runs on a single day, does this mean you unload the bags very hot and put them to your lab to cool down? Or is there a cooling function (including intaking air or something like that?) in the autoclaves?
