Is this one mycelium or two?
    #27094258 - 12/17/20 02:07 PM (3 years, 1 month ago)

I bought this ready-inoculated pink oyster kit from Amazon three weeks ago when it was discounted to $12. I figured for the price of a gourmet-variety syringe, I could get the fruits and see whether I like them enough to justify the effort of spawning and fruiting myself. It is a "Back to the Roots Organic Pink Grow Kit" that seems to be targeted for middle school kids.

When I got the kit, the bag had a small nick and the mycelium had colonized the cardboard near it. Other than that, it seemed to be in good shape. The odd thing about it is that it flushes alternately pink and tasty, and pale and stinky. The picture shows the stinkier flush and the pink just pinning. When cooked, the smell of the raw mushrooms goes away.



Anybody know if this is “normal” for pink oyster mushrooms? I biopsied and grew out some of the pink mycelium, and it looks very slightly pink. It looks even more pink in LC.

I wonder if I should wait for the next pink flush and biopsy from that to get a for-sure pink culture going?

That doesn't look normal. I believe you have pink and another oyster in there. You also need more air exchange. Those oysters need a lot more fresh air! Also, the bag is not taken off of oysters. I do a long slit in the bag from corner to corner but some people cut a few x's in the bag. Either way it is best not to lift the bag away from the sub when slicing the bag.

You are not going to get many mushrooms from that block. The pin set is too big. All the energy is going into making that pin set. Not enough energy will be left in the block to make good mushrooms. If you do get mushrooms they are going to be small.

Because the bag is removed and the pin set is so big. I would guess that block is done. It probably does not have enough water left in it to do anymore.

OK, do you want to volunteer, or maybe point to your favorite tek for oysters? I have three oyster grows in-process on oats and cardboard, different strains. Each one is grown from oats in a quart jar, then spawned to boiled egg cartons and wrapped in plastic. They look like this:



Since these aren't sealed, I can unwrap and check on them:



In the past, this approach has worked reasonably well, I got results that looked like this, with fruits on top as well as on the sides:



I have two more quart jars of mycelium on oats that I'll spawn this weekend. Would love your pointers or reference to tek.

I am guessing you do not have a PC by the way you are doing things unsuplemented.

I see you are in California can you get hardwood fuel pellets in California?

https://lignetics.com/products/bear-mountain-wood-fuel-pellets

https://lignetics.com/pages/store-locator

What type of bags are you using?

The main thing is to leave the bag on so you do not dry out your substrate. Then you just slice the bag and the fruits will form wherever you slice the bag. When you go to fruit you want to get the bag as tight as you can get it.

For instance, I would slice the bag in the 1st pick like his...



one long slice. It is best to not let the bag lift away from the sub when you slice but with the substrate, you are using it may be impossible.

One slice will make harvesting easier and you will get biger fruits because you are not losing energy to so many pins that will never grow like they should.

...Actually, yes, I have a pressure canner. I've been using straight oats, but I can definitely get hardwood pellets from a local hardware store. I'll check out the sources you suggest. Do you sterilize the pellets or just hydrate them? And what ratios do you use with spawn and/or cardboard?

I have a stack of egg cartons that I want to turn into mushrooms. I've found by sad experience that using dry cardboard leads to nasty mold infestation. Hydrating the cardboard with boiling water (like I would do with coir) seems enough to prevent the contamination.
Quote:

These are just 4mil plastic sheet, not bags. I layer the cardboard and oat spawn as in this video. The plastic I use is much heavier than what you see in the video. Once the mycelium consolidates on the cardboard, the block is stable enough to come out of the outer box (as in the pictures I posted). I fold the plastic over the mycelium block like a birthday present. The results look a lot like what you see in the video, though mine grow quite a bit bigger. Also, I'm using my own spawn produced by inoculating straight oats PC'd in mason jars. As I wrote above, using dry egg cartons as in the video seems to promote either cobweb or trichoderma; the boiling water fixes that problem, though it means the setup is less mechanically stable.

The times I've grown before, the mycelium kind of "grabs" the plastic, so I think the slicing would work. I'd probably want two smaller slices or X's so that the plastic stays together. In the past, I'd just unwrap the whole thing and try to keep it moist.

Thanks! I should see in a couple of weeks how this goes!

Ok if you already have a 23 quart PC then what you really need to do is buy proper bags...

https://myersmushrooms.com/shop/ols/products/200-mushroom-grow-bags-5-7-lb-14a

and fuel pellets and a supplement preferably soy hulls if you can find them and if you can't find them buy a bag of wheat bran.

The way I am going to tell you is the proper way to grow mushrooms. You can keep growing the way you are growing and have limited success or you can follow my lead and you will get at least 1.5 lbs 1st flush from every bag with little work.

one 40 lb bag of hardwood fuel pellets should cost you less than $6. A 50 lb bag of soy hulls should cost about $5. Out of one bag of soy and one bag of HWFP I get 33 five lb bags. 33 x 1.5 = 50 lbs. oysters sell for about $10 an lb. So for $11 in sub and $20 in bags you can produce $500 worth of mushrooms.

My point being if you are wanting to grow mushrooms to sell you can make a good profit. If you are wanting to grow for a hobby you are taking all the fun out of it by doing it the way you are trying to do it. You are putting more labor into it than it is worth and in turn, you are losing all the enjoyment. Buy what you need and reduce your labor and get bigger flushes.

Let me know what you want to do and I will help you either way!

You have to understand that this is only my opinion. You know what they say about opinions... they are like noses. Everybody has one and they usually have a couple of holes in them!!

OK,... game on! I already have:

  • 5 grow bags like the ones you describe. Also two with SHIPs.
  • 2 quart-jars of oats fully colonized with California-sourced oyster mycelium. These are the same strain that I've previously fruited from egg cartons.
  • Stove fuel pellets are available from a hardware store. There's also an arborist's yard nearby where oak chain-saw-dust covers the ground, but it's mixed with pine and other species.


Soy hulls are probably a mail-order item and would have to wait for the next round. I have coco-coir.

I'm willing to follow a recipe and evaluate.

I would not use coir. You want soy hulls or wheat bran as a supplement. Check feed stores near you. I get y soy hulls from southern states. It looks like there are southern state stores in California but you will have to call and ask if they have soy hulls. I use the pellets but the loose will work just the same. Pellets may be easier though.

Once you have the supplies use this to get your water content right...

Figuring out water content of substrate. TEK

Right now I would use one of your grain jars and G2G 12 more spawn jars. Or 10 I think you can only fit 10 quarts in a 23 quart PC. I sent you a PM so check for it.

Probably my other "weekend honey-do's" will keep me from running the PC this weekend. I have enough LC anyway to inoculate as many jars as I need for the next time I run the PC. They take about 7-10 days to colonize from injection.

And thanks again for the PM!!

Ok, that's cool. I personally hate LC you never know if it is any good until you try and use it. G2G is much more reliable.

I agree that fruiting block looks like it is on it's second flush... I've noticed the pink oyster smells like fish as it gets old... and turns less pink as it ages also.. mine looked the same on second flush...I have had luck with hardwood pellets with out any added bran as far as myco growth goes but I've not fruited yet.. I just pored boiling water into the wood pellets for a pasteurizes so my 2 cents would be not to use egg cartons.. straw (cheep)wood pellets (not cheap) coffee grounds (free if you drink coffee) would be my choices. I've got white oyster myco growing on/in my compost on my kitchen counter...on accident.  I put some mushroom cut off ends into it and forgot about it, a few days later and its killing it...in the compost...amazing how aggressive those mushrooms are... funny story my buddy told me about a wild oyster he picked and cooked and he said it smelled like pussy when he put it in the pan to cook...and I said it's better than the puss smelling like mushrooms.. and later on I grew the pinks and noticed they smelled like fish...I told him he was right about that since I had my doubts he was right about the smell... I've observed that oysters seem to explode with myco growth on coffee grounds..within 24 hours they sprout fuzz.

And so it was! The first flush produced nice big fruits. Then, I soaked it a second time and slit the "back" side of the bag to see if it would fruit again. That little carpet of pink and stinky pale pins stalled a few days after I took the picture, when they were about 1 inch tall.

Quote:

...I just pored boiling water into the wood pellets for a pasteurizes so my 2 cents would be not to use egg cartons...




The motivation for the egg cartons is they hold more water than wood pellets, which hold almost none. Their fiber has been recycled so many times before it gets pressed into egg cartons that I would not expect to find much nutrient in them, just fiber. I found out the hard way that the cartons do have active mold spores in them, so it is critical to do a long hot soak in a cooler with boiling-hot water. I've been putting the wood pellets in first, then boiling water, then layers of flattened cartons and more boiling water.

Quote:

...straw (cheep)wood pellets (not cheap) coffee grounds (free if you drink coffee) would be my choices.




What ratios do you use between wood pellets and coffee grounds? I'm  now trying cartons, wood pellets, coffee grounds and a small amount of gypsum. I'll have more spawn to play with next weekend, and I might try just wood+coffee grounds. I might try vermiculite or something other than cardboard to boost the field capacity.

Also, are you slitting the plastic wrap to fruit, or fruiting blocks in open air? That also affects CO2 and H2O in the block.

Thanks for all the input!

I doubt you needed to soak it. There is usually enough moisture in the block for two flushes. I personally never mess with a 2nd flush. If you are growing for a hobby I guess you could wait for a 2nd flush but if you are trying to make money it doesn't make sense. 1st flush is twice as big as the 2nd flush and takes twice as long. I can get one flush a week and not wast time and space on something that is going to give me half as much.

You think it is cheaper to grow on anything other than wood? Guess again the time and effort you put in cost you. Time is the most expensive thing when growing mushrooms. Plus you get a diminished yield when grown on anything other than wood and soy hulls. It costs e $10 to make about forty  5 lb bags. That $10 in sub makes me $600 and it only takes me a few hours.

I don't have soy hulls at this point. I have the other materials and I want to see how they work. I suppose I could just go big and buy a sack of masters' mix online, that's expensive,... Since this is just a hobby and experimentation, it's OK if yields are less than spectacular. At this point, it looks like the cheapest sack of soy hulls I can get is $28.75 from Amazon.

Then try wheat bran or just keep doing what you are doing if you are ok with it. To each their own. I was just trying to save you from some of the troubles I had. Good luck!!

I'm learning not telling anyone how to do anything.. I ain't a expert just observing.. I totally agree...if a supplemented wood grows more mushrooms its worth the time...and fuel pellets expand and produce a lot of sawdust..just straw and a few other things are dirt cheap..is my sole point..I'm not selling or making a business with mushrooms I just like to grow things and watch how beautiful they are.. and if my coffee grinds that I was composting anyway (worm food)can be put to use growing something I can eat..I'm happy to make use of them.. what I've seen as far as a second flush is put a wet towel over the fruiting block its better that soaking it..leave it for a week or so..the reason it stalled is you cut it again and that caused it to dry out too much.. and it takes time for the block to store energy to flush again... I've been using coffee grounds to grow out tissue of oysters I've not mixed the coffee to the wood pellets.. yet as I've not gotten the process figured all the way out but I'd guess you'd be fine to add 50/50 but remember wood pellets hold water very well inside the wood fibers  they may feel dryer and coffee also hold moisture well but molds do love coffee grounds and they are less likely to attack hard wood that coffee...or any other nutrient rich substrate IE grain etc...but I've got white oysters Myc growing in my compost bin on my kitchen counter right now it's growing on a coffee filter paper, a paper towel and banana peals and whatever else I've tossed in the composted...it was by accident I threw a piece of tissue in the compost and forgot about it..  SO I usually PC a jar of coffee and that eliminated any chance of any mold..its prob not required as a Pasteurizing will usually work fine..for oysters..as they seem to be super aggressive is myco state..
if I can figure out pics  I'll post some of the interesting ones..
