PE grow on coir, not the best by any means

I use an ultrasonic humidifier ... a single 3" fan ... and a 40 watt incadencent bulb... temperatures are higher than ideal.. very high 70's
This is like a martha tent grow setup except I make my own martha tents with wrapping thick painter's plastic around shelving units and I use a thin "clear" painter plastic for the top part.
Everything is on timers
3" fan and light go on for 3 hours and off for 2 hours.
ultrasonic humidifier is set on the middle of control knob. on for 1 hour off for 1 hour on for 30 min off for 1 hour repeating
That pretty much sums up what is going on with the tent.
Bulk process: I make 7-14 jars of grain and always have 2-3 as a master to perpetuate the grain 2 grain spawn colonies.
 I mix about 2/3 cup of spawn into a small cake pan and toss it around with 3 cups of pastuerized coir using Still Air Box sterile techniques.
They go on a heated blanket for 7 days.
 I then put a layer of pasteurized coir 1/2" thick on the colonized cake pan.
 I put it in the fruiting tent and wait 12 days for harvest.
Day 1

Day 9

Day 12

I'll make sure to make a better pinset on the next batch, using better temp and lighting.
I was using a blue LED light for the first week and although I'm sure it can work its frequency was too close to ultraviolet. It was a deep blue light. Switched to a 40 watt soft white incandescent bulb I know will get a full range of light that they like.
Also, I have better temperature control now... During the day when it could reach as high as 85, it will now only reach as high as 75. The first week of reaching those high 85 temperatures may be a big reason you see so much overlay in these pans.
They have been harvested patched and back in the tent. I do not cold shock or dunk, Doesn't seem to be a convenient way to do either of the two. idk..
If you're wondering if I should make my casing layer thicker, I consider it all the time, but I have yet to see a big enough positive impact by doing so.

Hello. I got today some coir brickets. Less than a half bricket I put in a bucket and filled with 2 liters of near-boiling water and then put a wooden lid on it. After a while I stirred it, and after another while I stirred again, for whatever reason. I ask because you do your pasteurised coir then in the SAB. Was it too much to open the bucked and stir twice?

no you're probably fine... it's all still hot and pasteurizing when you stir... my reason why I use sab when applying my coir is that I mostly don't trust my hands being clean. After I pasteurize a few bricks of coir I squeeze them to field capacity and store in gallon-sized freezer bags until I use them. (which can be a whole week) So I clean the outside of the bags, my hands, and try to stay clean for the mixing of the spawn and substrate.. After they are fully colonized and applying the casing layer I'm more relaxed (but I shouldn't) I had to throw away 2 pans today because of green mold. I always just raw dog adding the casing layer and it's a terrible habit. It makes 99% success turn into 85% success

Thanks for the response. O man, I just opened a door and the door hitted the wooden lid on the bucket, so that it got opened a little bit for a moment. The bucket is nearly at room temperature now. Is it now too much? xD I dont think, that I will repasteurize it tomorrow, except you would say its tto much.

coir doesn't contaminate as easily as grain or brown rice cakes... coir has a ph of 7 (so it's naturally resilient)

There's no need to pasteurize coir. Bucket Tek is perfectly adequate coir prep. Opening the lid isn't a problem. Not is touching the coir with bare hands. Just focus on producing clean spawn. If your substrate contams, revisit your spawn prep, because compromised spawn will very likely be the problem

Well, thanks again for the response! I read on the description of the bricket, that it has a ph of 5,5. Although they say its 100 % coir, they say there is uric acid in also. That is probably the reason for the lower ph. So, if I add a little gypsum, the ph should rise a little bit.

I want to go and say that the fact that you did pasteurize your coir.. (this includes hot water for more than 15 seconds) you are already going to see success with your grow. I have tried not pasteurizing and I had a 15% success.. I have tried pasteurizing and no further precautions and landed me around 60% success.. Now that I implement some SAB I have on average 90% success

Hot water for 15 seconds is nothing close to pasteurization. Bucket Tek isn't really pasteurization either.
Unless you had some really weird coir, your contams had nothing to do with unpasteurized coir. Correlation doesn't equal causation. Your problems were very highly likely from bad spawn. The main benefit of hydrating coir with boiling water is to cook it because the mycelium seems to like it a little better. Some people just use warm water from the tap with consistent success. Coir doesn't even contain all the good microbes that pasteurization is meant to preserve. Leave some wet coir in a clean bucket and see how long it takes to contam. You're gonna be waiting a very long time.
Sounds like maybe your switch to pasteurization just happened to coincide with improved sterile technique

Honestly, I wouldn't for this first grow. If you are using that brand in the future maybe consider something. Maybe use 3 liters of water? Try to wash off that acid they added. Gypsum is also ph neutral. Maybe crushed oyster shell (you buy it at tractor supply for feeding chickens)
my tests for the crushed oyster shells are still inconclusive. I have been using the crushed oyster shell on and off for a year now and even put some in my fish aquarium filter.. the results are underwhelming and unnoticeable.
@apples.. google milk pasteurization

Milk pasteurization is irrelevant to this question. Coir is nothing like milk. Just don't use dairy in your sub

do you not think the spawn may activate non-pasteurized substrate? Maybe it was bad coir.. But I will never use cold water to make up my coir ever again. Was a landslide of a difference. It may just be airborne? IDK, it's worth using hot water and doing any/some sort of pasteurization.

Lol, I did nothing with the bucket since. Maybe I will float it with water and sterelize in the pressure cooker, but not everything, a jar or so. Another part I could repasteurize .
Edit: today I looked in the bucket. There grew some mold I believe, some whitish threads on the surface. Right now are two glasses of good rinsed and squeezed out coir in the pc. The rest is simply in the open bucket to dry a little bit. xD
