Is this even possible?
    #22089854 - 08/14/15 02:10 AM (8 years, 5 months ago)

I came across this on Youtube. two things struck me: 1)They do not do anything to the grounds except press excess water out--no pasteurization or sterilization. 2)They introduce spawn into the bag of grounds with their bare hands?  Did I dream this? Or what?

They used gloves, and just because they did not say that sterilization was a part of the process, that doesn't actually mean they skip it...

Looks like there killin it! The nature of shrooms and there reproductive properties mixed with the free materials they get must make them a fortune. Good for them.

Right.  They are commercial operation so their stand point is going to be that of a business and they are not going to leak out all the trade secrets.

Looks like they are incubating the bags with a paper clip to keep them closed then sealing them with an impulse sealer before boxing them then shipping.  :strokebeard2:

Judging by the integrity of those spawn bags in that video I would hypothesize that they are sterilizing their bulk substrates/bags full of coffee grounds.

Well, let's say they do sterilize. And, OK, they are wearing gloves--but even so, how do they get away with putting gloved handfuls of spawn into bags while standing in the middle of a busy production room--no flow hood, no still air box, nada? Are they just offering a kind of video flow chart of what things are (sort of) done without giving away exactly how they are done?

It may be that the grounds they are collecting from Starbucks, etc., are considered to be pasteurized  by the fact that they have recntly been used in high temp coffee extraction processes. 

Well, I don't know. They should preface all this with the warning: Don't try this at home.

Oyster mushroom mycelium is very aggressive.  I bet they pasteurize the bags first which lets them get away with open air inoculation and insures the integrity of their product.

But yes, you can grow oysters on unpasteurized coffee grounds.  I used coffee ground spawn to paper bags last year.  I used way too much water and ended up having to squeeze a bunch out.  I also didn't shred my bags very well.  It was a mess and it barely fruited but it did fruit.

Here's a link talking about using oyster mushrooms without anything more than solar pasteurization.  They inoculate damp, unpasteurized, coffee grounds and spawn that to wet cardboard sheeting, and then too sun pasteurized straw (or whatever is available in the area).

King oyster mycelium isn't nearly as aggressive in my limited experience.  The guys in the video use pearl, the link uses golden, and last summer I used phoenix.

*edit*  Also check out eat's pink oysters on unpasteurized mulch.

Thanks for the eat's link. I am inspired. I will surely give this a try. Right now I am in the middle of a reishi attempt. That is also a very aggressive myc. I am used to trickier species--mainly cubensis--but these oysters sound like they are  forgiving almost to a fault. I love it.

the answer is simple...you're watching a 3 minute video

It doesn't matter what i think of you...all that matters is clean spawn

I'm tired do me a favor
