Is this good for the mycelium or no?

They seem to be colonizing nicely though.




Sometimes CO2 wells up at the bottom of a jar, which suffocates the myc from colonizing quickly. So flipping will help remove some CO2 and speed colonization of the bottom.

And yes, the verm barrier will be disturbed so be sure that the top is fully colonized.

you obviously don't know very much if you think the substrate being fully colonized is required for pinning




I forget, you noobs that have only done the PF Tek and watched RR's video know EVERYTHING about growing mushrooms :rolleyes:

A substrate does need to be completely colonized before pinning. If the substrate doesn't completely colonize and it pins, it means that something was wrong with the remainder of the substrate, whether contamination or lack of nutrients/moisture. At that point it's 100% colonized as far as the myc is concerned and thus triggers pinning.

If you need to flip your jars regularly due to a "too compact substrate" you need to work on your technique.

Scroll up the thread, I didn't say that, but we are talking about gas exchange here. Sure, some oxygen will replace the CO2, but most don't refer to this as FAE. FAE as far as what people talk about here is the frequent exchange of air required during the fruiting stage. You want higher CO2 levels during incubation and much lower levels during fruiting. The lower CO2 levels (FAE) during the fruiting stage is another fruiting trigger.

wtf dude
i've done way more than the PF tek

think about what you are saying man, are you really trying to tell me that pinning CANNOT be triggered without full colonization? seriously?
because i've had MANY MANY cakes that pinned before full colonization and i had to let them grow in the jar because the last half of the jar had not colonized yet, but it finished colonizing as the mushroom grew over the next week

Now, that's hardly fair to me now is it? Nowhere in any of my posts, nor anywhere in my video is there ever a suggestion that a substrate does not need to be fully colonized. It does.

Full colonization means the mycelium has captured the available substrate. It does NOT mean everything you put into the jar colonized. If there is a contaminant, especially bacterial, when the mycelium reaches the contaminant, it becomes a natural barrier, and it's just as big a barrier as the edge of the glass jar. When this happens, the mycelium senses it has reached the edge of the available food source, and thus pinning is triggered. In essence, your jar has reached full colonization.

Flipping pf type jars does nothing but allow a bit of space at the top, formally bottom of the jar, so that if you made the cakes improperly and packed them too tight, or left them too wet, they can finish colonizing. It has nothing to do with CO2 draining out which is a joke. Mushroom mycelium produces heat as it colonizes, and heat causes air movement. This movement rids the jar of excess CO2, whether the jar is right side up or not. It's ridiculous to think flipping a 1/2 pint jar lets the CO2 out, but it's totally unnecessary with 1 quart or 1 liter jars of grain, which are much taller, so by that reasoning, larger jars would have to be flipped-which they do not.

In addition, flipping a jar with it's only filter being dry verm is just plain silly. You cause the verm to shift around, and any contaminants that have been filtered can easily be transferred to the uncolonized portions of your cake. Make the jars up properly, not packed tight, and not too wet, and they'll fully colonize in two weeks at normal room temperature, like mine do. Make them wrong, and all the incubators and flipping in the world will hardly help.

Very well written post there RR
i was all angry before but now i understand..
almost.

How do mushrooms manage to grow in the wild without full colonization?

They respond to environmental triggers for pinning.

In the wild, the same procedures are taking place. The mycelium colonizes the available substrate and then fruits. Sometimes, the limits of available substrate are determined by the cold temperatures in the fall, thus fruiting is initiated with species such as shiitake and P nameko, etc. I've seen Hericium fruiting in the wild from the same tree for decades. Obviously, it didn't capture the whole tree the first, or even succeeding years.

Many species of mycelium are secondary decomposers, thus they can't even begin to colonize a part of the tree until some other species has finished munching that area. Thus, when the mycelium reaches that inaccessible part, full colonization is reached.

i just wanted it to be said
full colonization is not a requirement for mushrooms to grow
they CAN grow without full colonization, whereas it isn't optimal, it is possible.

thank you RR

"Nubs who have only ever done cakes"




That was a JOKE POST, notice the laughs? I was in a festive mood and made that post hoping to give a few people a laugh as that week we had had quite a lot of posts of people worrying the hell after not seeing any growth after 3 or 4 days.

I'm not saying I'm the most experience grower out there, but I have a few hundred cakes and a dozen monotubs under my belt since I started cultivating in 2005.

Those were not my first cakes.

RR didn't say that, in fact he confirmed the opposite. Fruiting will occur when all AVAILABLE substrate is colonized. That doesn't mean all the substrate on the jar and when we say 100% colonization we mean 100% of available substrate which IDEALLY should be the whole jar, unless you didn't do things properly, making part of the substrate uncolonizeable.

When the mycelium senses that whatever substrate is left inside the jar cannot be colonized (due to contam, over wetness or another reason) it will start to fruit.

But only once it colonized 100% of what it can colonize.

mushrooms definitely sense gravity...that's how they align their caps parallel to the ground for best spore distribution
