Bulk substrate colonization - seems to be taking way too long
    #23669224 - 09/22/16 07:45 PM (7 years, 4 months ago)

Started out with 5lbs of rye berries, fully colonized.

Spawned to two different tubs of hpoo, 10lbs each - so about 1:4 ration.

Hpoo was aged, no smell... in face, very aged... most of it was almost soil-like.

1 tub was not pasteurized, simply added a bit of water and mixed in 2.5 lbs of grain, drilled 5 tiny holes (1/16") into lid.

1 tub was pasteurized, a bit more moist as a result, mixed in 2.5lbs, drilled 5 tiny holes (1/16") into lid.

Placed both in closet and let sit... closet is temp controlled to 75 degrees.

It has been 11 days, and while the mycelium has grown around the grain, it doesn't appear to be colonizing the substrate...

1st pic is pasteurized, 2nd is not. You can see the mycelium is yellowing (waste products?)... so it doesn't appear that it's done growing... just concerned with how long it's taking...


Should I just be patient?

Just running a test... i've had success without pasteurization before, wanted to see the difference... might be regretting it soon...

if you don't pasteurize it it's already bad.
you should toss it out and start over without glaring mistakes.
there's resources in my signature for how to make bulk substrates that grow mushrooms.
save experimentation for after you have some experience and can change a single variable at a time with a proven culture

Anybody could've told you the results of this test without you having to waste materials..

hello OP, welcome to the forum!

bodhi's advice is spot-on. it makes it much easier to debug and figure out what went wrong when there are less glaring problems, might as well set yourself up for success

also, since the density of substrates is going to vary so greatly and with water content, we usually discuss spawn and substrate measurements in terms of volume rather than weight, and use field capacity as a reference for water content (err on the dry side)

you have had success without pasteurization before? with coir or with manure? id love to hear more about the specific context you are referring to, out of curiosity :smile:

even if you won the mycology lottery and managed to get some fruits off of unpasteurized bulk substrate in the past, it is certainly not something you could count on

in any case, you are in the right place to learn cubensis culture to your heart's content :wink:

Thanks for all the responses, i will definitely check out the posts...

What about the pasteurized batch? Any advice on that? I definitely had that close to field capacity (only a drop or two when squeezing a handful)... Is it normal to not have it fully colonized at close to two weeks after introduction of colonized grain?

how did you pasteurize it, specifically?

its not terribly unusual for it to take that long, what race/variety are you working with? i give stuff up to a month before i decide to move onto faster projects (most take less than 10 days with a high spawn rate, so i dont wait too long unless its something i am particularly invested in

they usually colonize faster as the colonies become larger, and if they arent it often indicates contam problems, either now or down the road

Maybe, excluding contamed sub, your sub is just too dense?  I alway mix hpoo with straw or verm at least to fluff it up a bit. 
And I have no idea what you were trying to accomplish  by testing an unpasteurized poo sub.

11 days and that progress?  Your sub is fucked.

So, that batch died and went to hell. I have since had some decent luck with bulk grows, but still learning.

I am having some weird issues with a new grow, will post in separate thread. Thanks again for all the advice.
