Coir NOT contam resistant
    #23954057 - 12/24/16 11:46 AM (7 years, 1 month ago)

On several occasions I have mixed up some bulk sub(cvg) in a 5 gal bucket and forgot to rinse it out. Then around 2-3 days later I open the bucket to find it full of white mold.

So why do people say coir is contam resistant?
Seems like coir isnt resistant to anything growing on it.

Thanks for clearing that up. I was unaware that they sterilize coir during production.

Wait hold on, that doesn't make sense to me. If it started sterile, and he added gypsum and verm, how did it contaminate?
That would mean the water used, the vermiculite or the gypsum has contamination. More likely the water content.

Mold will germinate optimally at 80-95% water content. A casing should be 50-66%.

There is your difference, not the items used or assembly.

Coir has very little nutrients, and has usually been buffered with with either calcium nitrate(i'm experimenting currently with this increasing yields, its just calcium and nitrogen) or the higher natural salt content helps inhibit mold.
Can coir become contaminated? yes, is it harder to contam than say hpoo, you bet your shit shooter :shitstorm:

I agree, I was just pointing the increased chance due to high water content, as the given example.
If you got a piece of kitchen towel kept wet, in air, after a long time you get mold.

Once a long time ago I was hot water bathing some pine pellets to remove the resins.
I stirred it once open air, two days later I opened the lid, boom mold.

Mold doesn't usually germinate that fast on pine wood.

Isn't that clear since paper towels are made of cellulose which can be eaten by bacteria, or am I wrong?

but isn't it common practice to leave it in the bucket to later case or just as needed for bulk sub?

I thought once bucket tek'd it would be fine for idk around 2-3+ weeks without concern of contam?

I've never seen it contam sooner but as said a higher water content might be the culprit or unpure coir. and for the record I have rarely saved it for that long.

I've got some of that in monos and in a bucket and no worries. Been in the bucket for weeks now. Was your bucket and lid clean? Lids can harbor nasties for sure.

This, and even if it did germinate, it would take a very long time to accumulate enough energy to get good growth.
I did a test with WL-Tek, although mold germinated after a few months, it was very weak and wispy.

I did not turn green nor mature for a very long time, around another 2 months.

Add some quick energy such as starch and it accelerates to weeks.

Tens of thousands of people have done the bucket TEK with zero heat(directions on the brick)
Then put it in a glass reptile aquarium and it sits there gets shit and pissed on and doesn't mold for weeks on end.
