From eight cakes, one only is fruiting well after a few weeks.
They've been left one or two days to a lower degree... There is indirect light humidity. Maybe the set is too basic ??

First, what do you mean by "fruiting well"?

Second, how long is "a few" weeks?

Are they getting light?

Also, I don't understand what you mean when you say "They've been left one or two days to a lower degree..."

In all honesty, from the minimal information provided, it sounds like your humidity is too low. For cakes you want a 95-99% rh during pinning and ~95% rh for fruiting. Whether you are using a "poor man's pod" or and automated terrarium, you should have moisture on the sides of the enclosure, at the very least until the pinset has formed and fruiting truly begins.

I will guarantee you that your set up is NOT too basic. At this moment, in addition to my "real" grow, I have several experimental grows going on. One of them is a tall clear rubbermaid box growing mushrooms from 4 cakes that were showing light or potential contam issues. There is no ventilation (other than my popping off the top and fanning it) and I hand mist it. I crumbled the two worst looking ones into a colonized substrate layer, then i stuck the other two whole cakes into the substrate and covered the crumbled cakes with dry vermiculite.

I keep the sides and top sprayed with water (1 spraying in the morning and 1 in the evening along with several fannings). At this point its been about 2 weeks or so since placing my stuff in there. I have harvested 1 flush from the "cased" part of this box, but the cakes have not even really started pinning yet. They look almost the same as when I put them in. Once the casing section is exhausted, or starting to show signs of it, I will be misting the box more vigorously and would expect the increased humidity to trigger the cakes to start fruiting.

Long story short, give some more details if you want better advice/help, but it sounds like humidity.

peace

Thx Snoozleberry !!!
I didn't explained anything at all.
The set is simple a first timer: cakes in a filter bag on a bed of vermiculite. 2 cakes by bags. I don't mist often and left them for a month, I inspect the vermiculite today and it looks like humidity is the problem here. But is this too late (over a month in room light, away from the window in a open cupboard).
I set them for two days next to a window to lower the temperature since I've read somewhere like sitting them a night in the fridge should shock them and might make them fruiting few days later...
So far one cake is fruiting well, another two have like small mushie staying bonzaï like (one cm tall and real funny looking)...
I may stash them all in a vivarium I have, over vermiculite very well moist this time and hope it grows...

Sounds like a good plan, if they haven't developed any contaminations, there's no reason not to give it a shot, I've heard of people getting great results with really late pinning/fruiting. I'd keep the cake that's doing well away from the other two and go ahead and give the slow growers a lil more humidity...Good luck!

Cool, so two month fruiting is not too late ?

well, it's most definitely on the later side of things, but with life, there really are no hard and fast rules. As long as the mycelium stay healthy/avoid contamination, they should live just like any other organism. They require food, water, and light (to signal fruiting). The cakes are providing them the nutrients (food) they need, so until they use up all the nutrients, that won't be an issue, and you control water (humidity) and exposure to light (like 12ish hours/day).

There are thousands upon thousands of seeds buried in any square foot of soil that don't germinate and grow because the conditions are not right to initiate such growth. If you take a soil sample you will find an exponentially greater amount of seeds than could ever spring to life at the same time in that given patch of land, instead the different ones gorw when the right conditions are present. Similarly, your cakes are essentially in a dormant state and are waiting for that water trigger to initiate the next stage of growth.

It IS possible that they have completely stalled or otherwise will not fruit, but A) if this were the case they'd be attacked by molds/contaminants and B) There's no reason to not find out if they'll still fruit, unless your water is really at a premium, haha, they're not gonna harm anything and it's always fun to see what nature/life can do. Besides if they do get contaminated, you can always chuck 'em into the woods/compost pile and see what happens, or just throw them away and you still won't have lost anything from where you are right now.

Thanks a lot. I put all 8 of them in a terrarium, on a well moist vermiculite, They are alltogether and three of them have start their fruiting as I see.
I have the feeling it'll be easy to keep constant humidity in the vivarium by vaporize the water in hte alley often from now.
Feel so good to grow life !

I couldn't agree with you more...now that they're in the terrarium, just make sure they get fresh air exchange. If you pop off the top like three times a day and fan the air with either a small fan or by waving a folder/book/board back and forth for like 15-30 seconds, that should be adequate. You may also want to mist the top/sides of the terrarium lightly like once or twice a day if you seem to be having low humidity again.

Happy Growing!

The humidity is maximum now and I harvested the first flush on one cake. Now there's some others growing on another two cake and they're all pinting the opposite way of the window.
My question is are they too close from the light source (window)?
Shall it be shadowy room ?

About the pictures, the second one was the first flush on the cake that I harvested now. The other ones are recent, you'll notice a different color of the cap, they did grow completely in the terrarium. A darker brown sign of maybe much more light.

mist them cakes with water three times a day, then fan the excess moisture briefly. the pic you showed is the ideal time to start giving them water. the fruits are 90% water, so they need to stuff themselves to get big and fat.

its all about high humidity, light, and fresh-air-exchange when fruiting.

if all them cakes start fruiting at the same time, its going to be a jungle in there. awesome. hope you take more pics, and i'll post some of mine when i find a place to.

just noticed something. the cakes are sitting on verm?

i'm wondering if they will try to colonize that verm. i sit my cakes on tinfoil, or the lids of jars. and then that's on a bed of moistened perlite.

if they can colonize verm, then that would slow down fruiting, no?

my understanding has been that when mycelium has colonized a BRF cake 100%, that it has depleted the source of nutrients, that it is a danger flag to it, and it will start fruiting so it can drop spores and survive where-ever the wind blows it.
