Trich problems, possible bad batch of coir? [Pet med eco earth]
    #26373940 - 12/10/19 10:38 PM (1 year, 2 months ago)

I started out with hawaiian spores and expensive prepared cow poo, that went off with 0 tams, but when I tried my hand at ground-up growing, I used producers pride oats and eco earth coir with a tek called a coir tek among an endless sea of coir teks. My first attempt went well, but subsequent attempts, all trich.

I even had a 5 pound spawn bag with PEU spores. The oats seemed fine, and then I added the spawn to some of the pet med sub and it colonized fine until I added a casing layer. Trich...

Is baking the coir at 200 for 2 hours too much? Should I just pour in 170°f water and seal it? Maybe i should use exo terra..

I thought maybe it's because trich spores are in the air. How should I go about cleaning my house? I've looked up "trich decontamination" but the search was inconclusive.

I seem to have hit a progress wall.

People always say if you get moldy coir, it's because your spawn was not clean.

My spawn IS clean. That I'm sure of. Out of 20 jars and other containers I see nor smell contamination. It has to be due to me prepping the coir wrong.

You can have subtle contamination that you cannot notice by smell or sight, is what the word is.  I didn't like finding out about that either.  I always thought if the jar colonizes, it's 100% clean

Just a little spot somewhere in the jar, contained by by all the cubensis, but when spawned, it all gets rearranged and it breaks out of it's containment.

A lot of mold mycelium is white as well, and only turns color when it sporulates. 

Mold is supposed to all be long dead by 200F too

If you used spores, your spawn is not clean...period.

For preparation of coir you pour boiling water on dry coir in a 5gallon bucket, close it, and wait for it to cool...that's it.


There's no such thing as a bad batch of coir..coir is a non-nutritious media that does not harbour contamination.

If your substrate is getting mold it's because you did not properly pasteurize your coir...again see bucket tek...or your spawn was dirty...since you used spores in this case it's probably both...

You should not attempt.grain grows without at least a fundamental grasp on mushroom cultivation...it's important to know why you do things...not just that you do them...

Unless you get it from a hydroponics store. They add Trich to it to promote root growth in cannabis. Of course it won't say it on the label, but they do it.

FWIW I have grown plenty of shrooms spawning to coir that was heated at 200F for 2-3 hours. I tried it after a suggestion here. It worked just as good if not better than the bucket tek, but I didn't take many notes.

I noticed no increase in contams. I've also used many bricks of eco earth and never found a problem that I didn't trace back to contamination somewhere. If everything you're spawning is contaming, it's highly likely the spawn...

Eco earth definitely does not do this.

Even the ones that do add trich so what...it doesn't germinate on coir anyway and if you bucket tek it you have killed any molds


--------------------

It doesn't matter what i think of you...all that matters is clean spawn

I'm tired do me a favor

Ive grown shrooms on unheated coir, bucket tek coir, and PCed coir.

Didn't notice much difference between the three.

Trich is a fungus, that means it has mycelium and that mycelium can look quite nice and white especially under low gas exchange environments.
A bit like mushroom mycelium, when given enough fresh air and moisture trich likes to sporulate.
Just because it’s not green in the jar doesn’t mean it isn’t there.

I used to think pasteurising is necessary with coir to avoid contams. Now I just add warm water straight from the tap, mix the sub and spawn... If I get trich, it is because of dirty spawn, the fuckers hide well in the jars.

Thank you for letting me know, I had figured home made spore syringes wouldve been better, but I'm probably getting something wrong. I'll keep my 3 buckets of coir in deep storage until my petris are ready.

Could. I use scrapings from agar to make a liquid culture in some malt water?

You can prep eco earth with room temperature tap water if you want :shrug:

I'll take a crack at that. Should I toss the spawn jars that I used spore syringes on?

Or shoebox each of them I have dozens of shoeboxes.
