Adding Hydrated Lime to bulk substrate
    #22108510 - 08/18/15 08:41 PM (8 years, 5 months ago)

Is it necessary to use PH Buffers on monotubs? Does it help with the contams?

Casings! Also good to add it to straw during the soak and pasteurization. Everything else is fine :smile:

So far I haven't heardbof anyone using lime in bulk sub's its very popular in casings though. I'm no expert by far but I wouldn't see a reason to use it in bulk sub's. But that's why I do small tubs to just see for myself sometimes if it does matter at all. Who knows if someone don't try. But I'd  deffinatly search for it long and hard it I were u. Chances are its its been done its on this site somewhere. I started an account here today and already have tons of questions answered. Its awesome

No & No.

Adding PH buffers to a bulk substrate comprised of pasteurized dung would spike the PH to a point that's unsuitable for mycelial growth. 

The reason why hydrated lime is acceptable to use in a pasteurization bath of wheat straw is becasue the wheat straw does not become fortified with the lime during the pasteurization bath.  Instead the addition of the lime to the pasteurization bath's purpose is to spike the pasteurization bath water's PH level to an unacceptable range for the existence of predator mold and bacteria spores that exist on the wheat straw prior to pasteurization.

:whathesaid: we use it in casings because they don't get fully colonized, bulk subs do

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

I'm tired do me a favor

Boooomm I learned something new as well. I'm terrible with bulk sub's I really need some advise on how to keep it sterile and clean and free of contams. I do everything as the teks say but still I deal with pesky mold.

look at your grain spawn, how you prep the grains and what you inoculate them with.
what tek are you following?

Hey guys - made a mistake in the post above.  The sentence about "Adding PH buffers to a bulk substrate comprised of pasteurized dung would spike the PH to a point that's unsuitable for mycelial growth" above is incorrect and misspoken.

Adding hydrated lime, specifically, to a bulk substrate comprised of pasteurized dung would spike the PH to a point that's unsuitable for mycelial growth is what should have been stated.  PH buffers such as gypsum aren't necessary to add to the bulk substrate in the way of adjusting the PH of the bulk substrate but are beneficial for the mushroom mycelium in all stages of growth due to the addition of calcium and sulfur.

The simple rye tek. Rinse drain rinse drain rinse again drain again then soak for 24 hrs. Then heat to boil reduce heat simmer for 30 45 mins until I feel rye its fully hydrated and firmly soft lol I know. Then I drain and load into jars with 3/4" hole stuffed with poly and a innoc hole healing rubber deelie foil over top PC for 1.5 hrs at 15 psi leave in pot closed to cool overnight then in glove box bombed hard with Lysol no scent and super fine mist of 91% alcohols let sit for 4 hrs then knocked up 2 CCS lc each quart then set on closet shelf little light to no light for about two weeks at most shaken 1ce every few days till 100% solid white brick. Since I got that down I've never a single jar go bad on me. Not one in two years. Lucky I guess. I gotta be doing something right.
Then here's where I go wrong. I've used I mean to the t. Lots of Bulk sub recipes and hardly ever get to a contam free first flush I mean half of a mono once had mold and other withnshrooms didn't and I ate em anyway but never had the huge white carpet growth like most people just a couple clusters here and there. I just don't know wherenim going wrong my mono looks just like all others 2 holes at top 4 at bottom good fae. Not too loose not too tight in the holes. Tub is sealed with clear cling plastic. Garbage bag at bottom under sub. 12 hr cfl bulb good air circulation in closet not blowing directly on tub. U name it. It has to be cleanliness but how to be sterile when tub is open to air while adding sub and spawn.


What to do.... Oh what to dooooooo......:confused:

Almost forgot. I do let it colonize first deerrrr holes covered and sometime with poly always in an black garbage bag then blanket over.  And it usually gets pretty close then goes south around 60 mayyyyybbbeeee 70% colonized then BWAAAAM!!! Muthafucken ass mold strikes again

Wish I could figure out why. I'm solo lost at this point

how are you making the lc?
spores to lc is risky, use 1 drop max if you do it, but rather put that drop onto agar first and clean it up!

I'm gonna try using a sealed air tight grow room type glove box bombed super atomicly light cans of Lysol and bottles of alcohol and put the whaol damn tub in garbage bag. Gonna pasteurise sub's in bags and everything in them cleanest syerilest damn way and place I can and I swear if it dontmwork I quit! .................. Lol probably not but I will be mad.

Well for.now I buy syringes from sponsors like sporeworks and such for microscopy research if course. Lol Till I get a grow with no mold then I'll learn to clone to agar and make prints and good lc. And spore syringes. Oh my bad. When I said I use lc. I meant spore syringes. Not actual mycelium liquid the spermy looking stuff. Sorry. Haven't gotten to that part yet

Grains once colonized can not be a source of contamination for bulks since they grow very fast and outrun the contams very easily.

I think the main problem of contamination in bulks is high temperature, poor pasteurization or over pasteurization.

Read this. Unless your jars look like that, it  isn't colonized clean. But you're right, those other things, if not done right, are a vector for contams.
