Surely you could be a little more creative/basic than investing one of those, how about using an old car jack?  Or making yourself a giant 'garlic' crusher... A good length of wood affixed to a wall at bucket top height, swinging plunger/press plate near the wall, put bucket under plunger, get on end of wood and squeeze. Sure, it's basic but that makes it cheap, easy to engineer and probably long lasting.

Nice! I have a couple of jacks laying around I use from time to time...will definitely put my mind to applying those. Thanks for the suggestion dude! You're right, I don't need to be elaborate. :smile:

I was also thinking about pulling the water out with lime (could help ph too), drying or even using a crude centrifuge. ie. An old washing machine with a cheese cloth bag and only on the spin cycle, wouldn't even need it plumbed.

Put it in a hessian sack and drive over it slowly? Or just park on it. It'll stain the crap out of your driveway.

Ummm...an old grape press would definitely do the job...maybe ebay?

I'm also trying to think of a ratchet method, again inspired by a jack, those huge 4wd ones.  Lay the bucket down, butt against a wall, base of the jack against another wall (brick hallway).

I guess I'm lucky I get my grounds from starbucks and they are all those little hockey pucks from the espresso machine and they come just about perfect moisture.  When I used to get grounds from a place that specialized in drip coffee they were a much soggier mess.

I'm going to be trying a new experiment this weekend.  I took 6 burlap sacks and pasteurized them and then spawned them with a block of colonized sawdust spawn.  I rolled them up tight and put them in a bag and kept them moist.  Now all the bags are totally covered with mycelium.  I'm wondering if I can fill these bags with coffee/straw and they will work without any additional spawn.  Or if I still need to add some.  Either way I think a pre-colonized bag will be an advantage for surface mold.  We shall see.

Hi MKF, i just want to clarify something about what you just described. Also, got any pics, that may help.  Ok so you took 6 empty burlap bags??? And sterlised them, then rolled 1 each around a pre colonised block?  Making a burlap spawn roll?  Then put that in an airtight bag to colonise?  Now the sacks are white you want to fill them with coffee??? And spawn??

If that's what you've done i think that's a very clever way of creating a contam barrier and yes it sounds like you are giving your mycelium a head start.  Very clever.

I like it! The mycelium should be able to work its way from the outside in. Granted, adding spawn throughout won't help but it's worth knowing if the burlap sack alone will do the trick. Maybe run a test: 3 with burlap spawn only and 3 with burlap spawn/grain spawn? Please update me I'm very curious!

Nope nothing like that at all. :wink:

My method is way simpler.  I grow out a bag oyster sawdust spawn from a wedge -> quart of rye -> bag of sawdust.  Then I took some burlap sacks and soaked them in 160+ water for a couple hours.  Then I took each bag and sprinkled some of the sawdust spawn inside the whole thing.  Then rolled it up and tied it with some twine.  Then I took a bunch of the rolled up sacks and put them in another bag.  I pulled them all out to take pics and they are going nuts.  Thick ropey mycelium and that sweet oyster smell.  I'm gonna spawn 2 of them tomorrow I think without any additional spawn to see what happens.  I have some good pics that's i'll upload soon.

You can also use newspaper, cardboard and coffee grounds.

I think it would be cool to figure out a way to make carboard/newspaper dust :smile:




Doing an experiment with yellow oysters in a few days. I have 4 quart grain jars now at 80-90% colonization, which I'll use to inoculate 4 bags. I am going to use as substrates (all enriched with wheat bran and gypsum):

1. 100% coffee grounds
2. 50% coffee grounds, 50% coir
3. 50% coffee grounds, 50% sawdust
4. 50% coffee grounds, 50% shredded brown paper grocery bags.

BTW, Yesterday I started fruiting a pearl oyster bag with 100% shredded brown paper grocery bags. We'll see how it goes!




Yes pls do post pics :smile:

I tried something like that with a pillow case. I had it hanging in a tree, but never fruited. :frown:

I filled 3 of these sacks today.  I decided to add some more spawn since I had a bag of grain spawn.  I think they're gonna work well.  I'm hoping the colonized sacks will speed up full colonization.  Now I gotta work on some kind of outdoor covered shelves for them.

Thanks for the link. Nope, haven't read it before. Will check it out when I'm at the library next. What did it teach you?

How to focus on the part of an overal process that should be improved. - Not the part that is the easiest to improve or "apparently" needs improving.

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

MKN
Really interested in the results of the burlab bag spawn, especially if you could fill the bag with straw then just slide that in a plastic tube-bag completely cutting out the need to mix GS with the straw. You could even use the final plastic bag as the spawn container by sterilising the burlap bag in it...
- That is assuming of course that the burlap has a nutrient base to it.

Well I have some updates in the area of coffee substrate. I've been pressing the coffee grounds to extract all of the excess water, and have adjusted my spawn to substrate ratio to 1:5 to 1:10 to get a faster colonization rate to prevent contaminant growth, "blitzkrieging" as I like to refer to it. These pictures show coffee grounds in nice thicket plastic bags I got online as samples.

And here is what it looks like today. This is five days into colonization.


Seeing how much money I've been spending on gas to re-pasteurize the coffee grounds and how much time and effort goes into it, I also adjusted my strategy and have taken the coffee grounds directly from the shop, pressed the excess water out then introduced a high amount of spawn without re-pasteurizing. I'm redirecting my time and labor toward grain spawn production. This makes sense because by creating spawn out of a smaller resource I can expand that resource into a bigger substrate without having to process the larger substrate (this really does save time and money).
Here are the results. The coffee grounds were acquired the same day I pressed them and inoculated them. Five days of growth.


And this would be pretty damn satisfying to me from a business perspective. But, I'm not yet satisfied. My original love of mushrooms is the fact that they can recycle abundant waste and turn it into food and compost. Instead of wasting money, space, and resources on plastic, I've decided to take an abundant supply of cardboard and utilize that as a holding container. What does this entail? More research and development! Here are some details with which I'm experimenting: does soaking the box under water before I introduce the coffee prevent the coffee from drying out? Can I simply add the damp coffee grounds directly to the box? Do I have to add any water? Time will tell! Will the cardboard box wick away too much moisture? Maybe it will be perfect as it is!

I made a spawn layer every half to three-fourths of an inch. This box alone took about 400 mL of grain spawn. I've so far made about 4 boxes. In a slightly larger box I used an entire jar of grain (600-700 mL of grain spawn). I haven't measured out the cubic inches of the boxes yet, but I'll have some more quantifiable data in time :smile:

Nice pics.  I actually did an expirement with straw in cardboard boxes thinking the exact same as you.  My hope was the entire thing would just fruit/get broken down until it was just a mound of soil.  One problem as you mention was that things definitely dried out.  I did mine on my back deck which was a mistake since it made a mess.  Doing it outside somewhere where everything can just break down would work well I bet.  Here are some pics of my attempt:







Either way I'll be curious to see your results.  Mine definitely fruited but not really enough to keep me interested at the time.
