Will dried grains topping spawn bags lead to contamination * 1
    #26517163 - 03/04/20 07:02 PM (3 years, 11 months ago)

With a low g2g ratio bags can take a couple weeks to colonize,
depending on location relative to HVAC registers the top grains of the spawn bags can dry.

An obvious fix is to shake the spawn bag and wait for recovery -
but realistically this will add days and days to colonization which is valuable time.

In the past when spawning I would brush these dried presumably (visually) uncolonized grains off before breaking up the bag to spawn.

For a simple test to see if removing the grains was nessecary last time I collected top dried grains from ten or so bags into a shoebox,
added CV, cased with CV and here we are...

I fold the bags over as to block the filter...Never an issue there’s always plenty of air left in the bags

I would say anything that is not colonized in your bag is going to greatly increase contamination when you Spawn it

Interesting so you try to cover the patch from having excessive air blow over it by just folding the top of the bag to drape over the patch?

I'll try your folding method.

It's very often not a problem, but in low rh, or if near an HVAC register very dry air will dry out spawn bags.

you're lucky if your environment is so that they will not dry, obviously you take steps to ensure this if I'm understanding your post,
so it seems it may be effecting you enough to take that step.

Garenteed using a lower g2g ratio than you.

I thought the dried grains would increase the contam risk as you thought, figured I'd do this test and find out.

After all as I use ONLY the dried grains in this shoebox mind you I say VISUALLY uncolonized/dried grains and it turns out absolutely fine then I will reconsider if it does in fact lead to increased risk, because seemingly so far, they must be colonized, but just dry because it looks fine.

So let's find out. I'll update the progress over the next week or two.

Are use 1 1/8 cup of wheat to 1 cup of water

My area is in a walk-in closet with a small space heater but on longer colonizing mycelium it does want to dry out toward the filter patch so I just fold them over and lay the bag on top to keep it closed

I have 19 bags of truffles that would never survive unless I did this I will post a picture later

I seen somebody scope the dried grain and they all had mycelium on them, plopped on agar they all grew beautiful isolates

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

it was brought up when somebody made half inch holes in his grain jars and the tops dried out, a few of us just said spawn it( I always do n never seen it be an issue) so the dude simply scoped some lol, I don't recall the name it was a couple years ago in the fb group

:takingnotes:

I’ve taken to shaking everything @ ~75% 4 days before spawning, since I’m on a regular schedule this works fine for me, but I had a heat spike(83 f) in an incubation room that made bacteria go nuts and I threw away a few bags, didnt want to shake the rest because I wasn’t sure they’d recover and only ended up spawning 1/2 of what I wanted to today because the rest had dry grains up top.

Glad I came across this thread.  Just had half my bags that wouldn't finish the top grains.  All the masters were really nice.  Was worried it was a contam coming in from the filter patch, but there wasn't any sign of mold or bacteria.  Ended up spawning them to see what happens.  Makes me feel 5% better that it might still be ok :rofl2:

Couple spots of green. Seems like if you're not combining ten different bags dried grains worth it'll be fine.

I'll update one more time but I have my conclusion.

They look like they need more FAE the tall skinny stems as they try to reach up for air

I switched it to a dub tub with some more air flow. Not really caring about the yield on this but good thought.

I didn't measure the amount of grain, but by estimation it was no more than a qt.

90% of first flush turns out to be 1.16oz dry.

It's just from drying, I left the top tub very open. Neglected.

I spawn bags with uncolonized dried grains on top sometimes. Never been an issue.

Sounds to me like your grain prep guy needs to boil the grain longer. Get it hydrated to the center so it won't dry out. That's how I solved this issue.

I have some grain jars that seemed to have stalled over the weekend.. just a few uncolonized grains on top.. think I'm just gonna spawn them tomorrow..

Gonna try boiling my grain longer too.. glad to hear it's probably fine to spawn

I've spawned jars with uncolonized seeds on top a bunch of times
Never gave me a problem
