Itโ€™s doubtful everything would be contaminated. I keep only a couple of like prints per ziplock.

Thank you. If I put the spores in the same space as other spores, are they all tainted? Like the spores on foil, in a little ziplock bag mixed with other spores on foil in zip lock bags?


Depends on how/if you fold the foil.

Yea they were all folded and put back into their respective zip lock bags but wondering if the spores got on my gloves which got over the zip lock bags that went into the bag with all the other zip lock bags.

Most prints are 'tainted' to begin with.

Shuffling prints will spread spores but isn't this about black pin mold?

The lion's mane is confusing me a bit, haven't worked with it indoors and want to know if my bulk spawn is ready. We're day 13 here's day 12 photo's below. Put to substrate and poorly distributed (not going to lie, bad job on my half). I got some spots not colonized yet but the rest is screaming, got metabolites of amber droplet colors forming near the top; no formation of fruits yet. What do you champs say, this was some of the wispiest mycelium I've worked with ever but on substrate really starts to shine.



I did a bad job distributing the grain into the bags and mixing it so it's a bit of a shit show. When would you guys send these in to fruiting given that's day 12. Not much different day 13.

Thank you champs, I got more Lion's mane on the way! This culture is hard to see without light and camera with macro. I see others with crazy colonization (all white) so yeah this isn't one of those strains at least out of the jar with grains. this is a picture of the jars off the phone below with some lighting.

day 9 jar colonization:


Day 14 jar colonization:


Just being safe these are different! :laugh:
I see so many differing videos online and here even, just want to be clear with the growth still I get this under control. Wish I knew what my wife bought me, we could be growing mold! :laugh:

Yes it is. Both the plates I got from a giveaway had the black mold so Iโ€™m worried itโ€™s from the spores.

see "water agar" if concerned about 'dirty spores.'

~Agar~ 1000mL water = 1000g water. use ~1% agar...1% of 1000g is 10g.  For cubes, use between 1-2% nutes (10-20g). For pans use 0.5% nutes (5g).

What benefits does adding verm to coir have, if any? I've seen some people swear by just coir, other people swear by CV. I'm only asking because I've read different answers every time I try researching it. The only conclusion I could come to (which I'm unsure if it's correct) is that it helps with field capacity.

It's purely a water reservoir, if you add too much water to coir it is faster to add dry verm to bring it to the required field capacity.

It's a preference thing.  Verm adds texture and a little more moisture holding capacity, it's definitely not needed tho.  Any more I use it out of habit.

Vermiculite helps hold (retain) more water in the substrate. For the mushrooms "field capacity" is what you want in terms of substrate hydration. If you add too much water to the coir when preparing the substrate and it's wet and soggy then you can add the verm to correct the hydration.

Yep, just a crutch as far as I'm concerned. I started on that CVG and then dropped the gypsum because it's absolutely pointless. Then got sick of buying and mixing verm. Or maybe I ran put of verm one time and just said "eh, fuck it. " I honestly believe that in most cases, people just get used to a way of doing things and then just keep at it. Verm can be used to soak up extra water, but if you constantly mix verm into your coir, then you never know what coir at proper field capacity actually looks like. In my personal experience, I found that in the long run, it's easier and less work to just dial in my water content. Not having to mix anything else into my coir saves a ton of time and aggravation. As does not having to pick flecks of verm off my fruits, not having to clean up verm off the floor, etc.

I also have to be annoying and drop my usual lecture here. Coir is not perfect from a sustainability or health standpoint. Probably not great to breathe in dry coir, and coconut plantations are a bit out of hand right now. BUT coir is just a by-product of the coconut industry. That's part of the reason it's so damn cheap. And the overall health hazard is just "yeah, you could breathe in some of this fibrous dust and be a little irritated." Vermiculite, by contrast, is a mined clay that's exploded into that light and fluffy final product with intense amounts of heat. So, mined, and then transformed via a massively energy-intensive process. And breathing in vermiculite dust is pretty damn bad for you. While in the tubs and hydrated, it won't be kicking off dust. But when you're first mixing it in, it will. And when you're pulling fruit out of the dehydrator, it will. And when you're sweeping it off the floor, it will. Also, at least in my neck of the woods, it's expensive as fuck.

No judgment on what people decide to do, but they should at least have all the facts.

Also, one other thought: I think a lot of people (myself included) basically ended up replacing the extra water retention of verm with higher spawn ratios and more highly compressed subs. I run my coir drier than I used to because I don't want to deal with it dripping and I don't have that verm to soak up the excess. Then I add more coir per quart of spawn, and compress the sub down more to make it the same thickness. That essentially translates into more water.

Thank you all for the info! I'm glad to hear the answers, I've been keeping verm around in case I'm over field capacity. I swapped brands of coir so I'm having to fine tune how much water I need to use. I've been using it as a crutch, so I'm happy to know there's not too many inherent benefits other than that. And I'm in the same boat, vermiculite is pricier than what I really want to pay for. The dust really sucks, I have terrible sinuses so I wear masks anyways, so knowing I can just avoid it all together helps

I replaced mine with biochar recently.  Which is somewhat the opposite in its moisture retention but it adds texture and does some other cool stuff.

Granted I case everything with peat and calcium carbonate (again no verm).  So there's good moisture holding capacity on the surface without verm in my projects.

And I know peat has its problems as far as sustainability.  But it's taken me 3 years to go through one bail.

Or just squeeze the coir with sanitised, gloved hands until you've got a few drops coming out. Works for me :shrug:

So I am on my second flush of some GT PF cakes and I have a lot of pinning going on the bottom of my cakes. For one of these, I decided to flip the cake so the pins are now on the "top" facing up (pictured below).




Others I am leaving. On the one hand they're clearly happy with the conditions down there but on the other hand I feel like it's stunting their growth so I figured I'd try flipping one to get the pins facing up to see how it does. Any idea of one method is better than the other in terms of flipping vs not flipping these?

Re:  Inverted sugar.

It looks like some FAFO from a bit of digging on the net.  As no basidomycocytes are currently shown to produce invertase from what I gathered (it's made by yeast for folks following along).

My suggestion would be to make a small batch of agar with it using your standard ratio for other sugars and see how it does in a side by side.  And then let the rest of us know here how it goes.

TreeFrog, do you use the pelletized charcoal that is marketed as biochar?

Biochar is charged and inoculated charcoal, IMO.

so it wouldn't be biochar until after the fungus have their way with it, or maybe it would be mycochar

Re: Ask Quick Questions, Get Quick Answers [Re: Generic]
    #29498535 -

I got stuff that was charged at first, but it was expensive.

So I got a larger bag of pelletized charcoal that I will mix with worm castings and water, prior to mixing it with coir.  I think it was still marketed as biochar, but yeah it's not charged with nitrogen or biologically active without help.

But mostly my consideration for using it is texture and cation exchange.  I'm sterilizing it anyway so the microbes won't survive.  Plus worm castings aren't the most breathable substrate additive due to particle size, so it balances them out.

I'm not using much though.  Like 5% by dry weight or 10% by volume.  And that's enough to make the substrate springy like a sponge once it's colonized.

I just squeeze mine with my hands if I have to, no need for gloves or a procedure.  Your hands should already be washed if you're doing mushroom work, and that's plenty enough for spawning.

Remember, by the time you are spawning, sanitary work is over.  You either made clean spawn or your spawn is contaminated.  It is exceptionally rare for the contamination to come from the coir itself.

Unless you do something stupid like I did and make coir in a bucket you used to spread compost around the garden and didn't wash after.
