PF Tek - What am I doing wrong / why are my first pins looking like this? (pics)

Howdy all!
So, I'm a little bummed. It's been a good PF Tek so far. The cakes fully colonized and consolidated for a full 7 days. They were dunked for 24 hours and rolled with fresh vermiculite. The cakes seemed eager to fruit while in the jar (some pins were developing inside of it).
The shot-gun fruiting chamber is up to spec, brand new perlite, hand-width deep. I've been spraying and fanning.
It has been about 4 days in the SGC, and the only two pins from three cakes look completely weird. So small, uneven in color and their veils are opened already. They just don't look healthy.
I'm wondering if I'm spraying too much? I spray and fan about 4 times a day.
What do you think? Any tips would be greatly appreciated.

Don't count out genetics. You'll experience different results every time with multispore.

Are the four corners of the SGFC held up by jars? Or anything?
Can you post a full pic of your FC? Chances are that is the problem

Yep, it's elevated by four jars. Here is a pic of the whole thing:

Thanks for helping out.

I don't know if I'd put my SGFC right on the carpet like that, but your fruiting chamber looks good (as long as it has holes on the bottom).
I'm sticking with genetics.

Looks pretty wet. Are you waiting for the water to evaporate before you mist again? are there holes in the bottom of your SGFC?. Are you misting first then fanning? Otherwise it could be genetics.

Hmm, there seems to always be water drops on the foil next to the cakes. I spray even if there are drops of water like in the pictures in my original post. I spray first and then fan. Is that what I'm supposed to do?
Thanks all!

Well your setup looks pretty good to me. How heavy do your cakes feel? If they are fairly heavy you might want to try misting a bit less, let them dry out a bit. Waterlogged cakes will not pin well and if they dry out a bit that might help (moisture loss from the substrate is a primary pinning trigger). I'm no cake guy by any stretch but those look pretty wet to me. If that does not help then it may truly be genetics, in which case you can hope for better luck on your second flush.

get a lamp and set it to shine light in your FC. Turn it on and then forget about the FC for 24hrs.
I bet when you check on it there will be an explosion of growth

Not from just 24 hours of light.

""Lighting Requirements of Mushrooms
Some mushrooms, such as the Agaricus species commonly found in grocery stores require no light at all. However, those commonly grown by hobbyists, such as Pleurotus ostreatus (Oyster Mushrooms), Lentinus enodes (Shiitake), Psilocybe cubensis, a hallucinogenic mushroom, and Hericium erinaceus (Lion's Mane) all require light to produce abundant, normal sized fruits. Experience has taught us that the light best suited for primordia formation and the development of fruitbodies is bright light with a color temperature of 5,000 Kelvin to 7,000 Kelvin. Fortunately, this type of light is easily obtainable at your local home improvement center in the form of fluorescent fixtures. For a small terrarium as described in this chapter, a single CFL (compact fluorescent) that screws into a standard light bulb socket will work very well. These can often be found in grocery and drug stores in every neighborhood. 15 watt CFLs will do the job well, but the package will probably have a large 60 stamped on it, indicating they produce light "equivalent" to a 60 watt incandescent light bulb. They're referring to lumens of output, not the frequency. Incandescent light bulbs are the worst possible choice for growing mushrooms, since they emit a 'red' light in the 3,000 Kelvin color temperature range.
The higher the color temperature, expressed in Kelvin, the closer to the 'blue' end of the spectrum the emitted light is. The lower the color temperature the 'redder' the light is. If you have a choice of fluorescent lamps, purchase those labeled 'daylight' since these have a somewhat higher color temperature than cool white. Daylight, sometimes called 'natural daylight' fluorescent tubes generally emit light in the 6,500 Kelvin range, while cool white fluorescent emits light at around 5,000 Kelvin. If you have several terrariums stacked or otherwise near each other, you can use larger 2 to 4 tube fluorescent fixtures. These come in 48" and 96" lengths. Place the fluorescent lamps as close as you can get them to your terrariums without causing excessive heating. Species such as Shiitake and Oyster mushrooms prefer to fruit at temperatures in the upper 50's to mid 60's Fahrenheit (15C to 20C), while Psilocybe cubensis prefers to fruit at a temperature in the mid 70s to about 80 Fahrenheit (23C to 27C) Most mushroom species don't mind a slightly warmer temperature during daytime than at night, so if your grow room is a bit colder than the temperature ranges given above, a little warming from your lights during the daytime won't hurt at all, provided you don't let the air in your terrarium get too dry. For cakes, try to keep the humidity above 95%. Cased substrates are a bit more forgiving, but still try to keep your humidity above 90%. 12 hours on, 12 hours off has proved to be a great combination over a wide range of species. Of course, if you have a bright window near your terrarium, that will suffice, but direct sunlight for more than a few minutes per day should be avoided. Disregard outdated advice in old books which is constantly repeated on the internet to colonize mushroom substrates in total darkness. Experience and rigorous peer reviewed studies have proved that exposure to low level ambient indoor lighting during spawn run and substrate colonizing will speed up the process, leading to full colonization up to a few days earlier than the same substrate would if colonized in darkness. In addition, mushroom mycelium develops a day/night circadian rhythm, so exposure to light from day of inoculation sets this process in motion, leading to earlier fruiting and harvest.""

I was just telling him what to do to set it and forget it....
The cakes have been in there for days. There will definitely be noticeable activity in 24 hrs.
I've done PF tek and from pins to picked fruits was two days.
I'll spare you the irrelevant pasta though.

Yes, there will be a noticable difference in the fruits that are already there, they will not stop growing silly.
But with MS it is a crapshoot every time.
There is no way you can know for sure what will happen and/or when it will happen.
Spores will always give you unpredictable genetics.
Just because your (insert variety here) acted a certain way one time, does not mean it will act like that every time.
This is why we isolate single sets of genetics on agar.
To get more predictable, repeatable results.

I think I may know what what the issue.
While doing some reading, I stumbled upon a comment by RR saying that any unnatural wind currents will affect the mechanics of the SGC. I moved the SGC from the carpeted floor to a closet (on top of a dresser, so I also elevated it). The room I had it in had a ceiling fan going on all the time and I believe it was interfering with the normal airflow that the SGC should have.
Just a few hours after doing that, the "mutant" pins that I had started growing and I also noticed a new pin on a cake that has only been in the SGC for about two days (and looks quite normal).
So in summary: a room with higher temperature (around 78F), less unnatural air drafts, and elevated the SGFC:

I bet that had a lot to do with the issue. I can see how having a fan always on would mess with the SGFC. The currents that occur, drawing moisture from the perlite bottom and flowing up into the FC, Id imagine, are probably pretty "light" and an overpowering ceiling fan could throw them out of whack.

FWIW I had a ceiling fan on in the room with my SGFC during the summer since it was so hot and it really had no ill effect on the performance. Not that it's recommended

Thanks for asking! They are coming along, but nothing spectacular:

I can't seem to get awesome set of pins like this example:

So, I got two hygrometers. One "humidor style" and the other is a terrarium thermometer / humidity combo. I placed them in two sides of the SGFC and they both agree at 80% humidity. I hear that humidity needs to be at 95 to 100%. At the same time, I have a problem that my cakes look too wet! How do I increase the humidity without making the cakes too wet? I hear that if the cakes have too much water, they have no motivation to grow pins and attempt to produce offspring by creating mushrooms and then sporing.
I've been spraying the perlite more than the cakes to try to solve the humidity issue, but no luck yet.
Any thoughts? Thanks again!

It might just be water content of the original mix before you steamed those jars. Waterloged(heavy cakes and easily mushed) batches just don't perform I error on the dry side if I'm making a cake.
 The cakes I get that pin like this are always light and crumbly not heavy and mushy. Like if you were to squeeze on them they wouldn't mush through your fingers but break apart.
Although sometimes with that prolific of a pinset it's hard to avoid aborts so when mine pin like that I sometimes put them in a dish of water like a pyrex cupcake sized dish thing.
The only time I had waterlog problems is with full pint cakes but those even perform extremely well if you cut the water down a bit, how much is hard to say you really just have to get a feel for field capacity

80% is waaaaayyyy too low. That's your problem.
My humidity monitor always registered 99%
Your perlite was fully hydrated when you put it in? and your temperature in the room is ~80 degrees?
If the above are correct then you need to start taping some holes in that SGFC

You have been a member here for less than 2 weeks, so I will be gentle when I say this.
Do not give advice on shit you obviously know nothing about....because taping the holes of a SGFC is not going to help anything.
If the SGFC is built right, there is no need for a hygrometer, as the humidity will be perfect.
If the chamber is built right, my first guess would be a faulty cheap uncalibratable unreliable made in china hygrometer.

Howdy Notahacker420. I'm hoping that is the case. In my forum searches, I've seen RR say the same thing. I believe I built the SGFC to spec (a picture is earlier in this thread). The perlite was hydrated per the RR video.
Question; what is the impact of the size and quantity of holes in the SGFC? Especially in the bottom of the SGFC.
Thanks again!

1/4" holes every 2" in a grid pattern on all 6 sides, top and bottom.
Any more or less holes, or bigger or smaller holes, and the chamber will not function as intended.

He has two humidity monitors, both telling him its 80%, which is way too low for cakes primordia to form and pin ideally.
I have never heard of two freshly bought humidity monitors both giving the same wrong humidity percentage.
If you were to tape some holes, it would raise the humidity. I had to do this with my SGFC, although his looks a lot nicer than mine as though he did make it correctly.
The way the cakes are going it's a pretty shitty flush, he's not going to get much, why not tape a few holes on top and see if it raises the humidity?

Even if both those gauges are correct (which I doubt), do you think that the RH at the surface of the cake (right where the pin formation is going to occur) is at 80%? Taping up the top holes will not raise the humidity anyway. If low humidity is truly the OP's problem (maybe from the fan drying the chamber out), then the way for him to increase it IMO, would be to re moisten the perlite

If the SGFC was properly built, taping any holes would actually lower the humidity.
But don't take my word for it....let's see what the chambers' designer has to say about it....

RogerRabbit said: This is extremely bad advice, which has ruined many growers efforts over the years as the search engine here clearly shows. As fresh air is entering and leaving the shotgun terrarium, it's absorbing moisture from the perlite, which is re-moistened each time you mist. Taping holes LOWERS humidity as thousands of noobs have already found out. Humidity NEVER 'leaks' out of a shotgun terrarium. Nature abhors a vacuum, thus as air exits a shotgun terrarium, fresh air is being drawn up through the perlite, creating more humidity. I fail to understand how this basic engineering concept is so difficult to grasp. 
Further, new growers often incorrectly think that humidity is the most important factor, thus they screw up their terrariums trying to make the walls covered with condensation in order to satisfy their piece of shit walmart chinese hygrometer which doesn't work. In addition fresh air is the number 1 pinning trigger, so build the terrarium per the tek and don't tape the darned holes.
There should never be side winds against a terrarium. This is not an outdoor tek, but an indoor one. I've always recommended against running a fan in the room with a terrarium. The shotgun terrarium is engineered to work with the natural air currents in a room, not artificial fan-induced wind. RR

So like I said, do not give advice on shit you obviously know nothing about.

Thanks for the great advice. I moved the SGFC to walk-in closet where air currents are not as bad. Hopefully that's it.
