What might be causing this uneven pinning?

The substrate was fully colonized and starting to form pins when I cased it. Is the uneven pinning a function of this clone, overlay, too little or too much co2 or other factors. Is there any way to salvage the rest of this flat? I have never used bleach on a casing. If you have experienced this I would greatly appreciate your advice.

Assuming that the substrate is plenty wet..What is your FAE schedule?

Fresh filtered air twice a day. I do not even know I made this post like it is. I should have asked if a misting of a 10% bleach solution would improve the overlay that I think might be the problem.

Thanks again oibchip.

could be your casing mix
what is that?

Judging by the amount of myc on the stems and the suspected overlay, I would say that the Co2 is too high and maybe your temp is too high, also. I would lower the temp and increase FAE. I have had casings with uneven pins before. I narrowed it down to the strain. After the first flush, some strains need 4+ days to start the 2nd flush....but I have had strains that grow new pins before the first flush matures. ~Skunk

10% bleach is way too much. I don't use bleach water at all when misting but if you do the ratio should be around 1:200 bleach to water.

Like skunk said, increase FAE. Maybe to 4 or 5 times a day unless you want to put holes in the side of your tub plugged with polyfill or tyvek then u might be able to get a way with 2 times a day.

Casing mixture is 15% coir / 15% vermiculite / 70% water by weight then pasteurized. Temperature 70 to 78. The tub has 1/8” holes with doubled micro filtration vacuum cleaner bag taped all around. I did not know that mycelia on the stems meant too much temp and Co2.

Thanks

When you're colonizing your sub, it is locked in your jars (high Co2) at a high temp, which equals mycelium growth. ;) Your temp is fine: 70-78. Since you DO have filtered holes in your tub, try putting an oscillating fan in front of it. This will help increase FAE when you're not around to fan it. :) ~Skunk

Good advice recommending the fan. Definitely is a c02 issue by the looks from those shrooms - long shinny stems and mycelium puffing up the base.

Fahtster has a great tek on late casing. I have tried it a couple of times a few years ago and recently again when I saw Fahtsters beautiful flushes. But, I never did get it down pat and always found rotted pins under the casing layer. I'm sure it was user error on my end. I prefer not to case anyways.

Mr natural, 3-5% agriculture lime in your misting water is better and healthier then bleach or peroxide as a disinfectant when in need of a preventive measure against contams. It maintains the ph of the substrate and casing in the alkaline range without harming mycelium or shrooms - resulting in further flushes. I'm sure you have by now but, those two large fruits are ready to be picked. :)
Also, given the advice on this thread to you I will add that you let those pins ride it out and grow. After that flush scrap off the casing, dunk and then re-case.

Hope to see some updated pics.

Sooshane: If you're getting rotted pins from the late casing tek, (You've probably figured this out by now) Your casing layer is too thick and maybe too wet. I also used Fahtster's late casing tek for the first time 2 weeks ago, and it turned 3 fruits into 17 on my SA casing. Thanks, Fahtster. Don't give up on the late casing tek, sooshane. I also stopped using a casing layer when I started spawning to hpoo. The fruits only grew around the sides. With this new tek, they grow all over the top, not just the sides. BTW, You hit it right on the head when you suggested lime and to harvest the big fruits. ;) ~Skunk

Yeah, know doubt that I did lay it on thick back in the day. The last time around I only went about 1/4" -1/2" thick... prolly was just immature pins unable to break through or just abhort to begin with. I tried this in a new locale that is drier then I am used to so, like I said it was prolly user error - me being over eager with the misting. No doubt Fahtser has it down pat. Cheers!

i usually just sprinkle the casing on til it just barely covers the myc. Never had good luck with thick casings.

are you piping in the filtered fresh air? that could be the culprit right there.. with my experience, I've had bad luck with just piping air in.. the problem with that is that you aren't exchanging the air completely.. you may push some out while piping in but twice a day isn't enough. you need to completely remove the stale air.. if you do pipe fresh air in, you should also at the same time pump the old stuff out. the fan is a good idea.. esp. if you aren't pointing it directly at it.. just keep an eye on it for awhile after you put the fan.. make sure it isn't drying it out too much.. but with the sized holes I see.. oscillating would be good. I would also agree that FA is the culprit here eh.

hard to tell from your pics but something is definately amiss.........

let me first say this ---- when it comes to casings and uneven pinning ---- most of the time this is due to an uneven casing layer ------allowing some area to pin faster while other struggle though (multispore can also play a role) ----- The fix for this universal problem ----USE DEPTH RINGS for your casing layers

now, your incident looks different ----

my guess is by covering the pins with mix, you may have caused some aborts, and the layer may be uneven, (perhaps unevely moisturized as well) --- Personally i'd scrape it off, and re-case sub --- buts thats just me --- looks pretty good otherwise
