Simple questions about bulk substrate
    #22426286 - 10/24/15 09:00 AM (8 years, 3 months ago)

I'm new at this and I need some help. I did some research, but I'm confused, so any kind of help would be useful and appreciated (I'm talking abut tek links etc, though I did read as many teks as I could find).

The questions:

1.What would be the best bulk substrate out of: vermiculite, peat moss, manure (store bought)?

2.Would millet suit fine as a spawn?
Following question
2.1 How to prepare millet?

3.Why pasteurization is better than sterilization (for bulk substrate)?
Following question
3.1.Would it be really bad if one per se sterilized bulk substrate?
Following question
3.2.How bad?
Following question
3.3.How to pasteurize without a thermometer?

1 none listed

2 same as other grains

3 pasteurization allows beneficial microbes to live vs killing them.
3.1 no I do it all the time
3.2 see above
3.3 use your finger and don't let it boil.  (Send me your address and I will buy you one for 99 cents on eBay)

It's ok. :laugh:

Oh, and, about he first question: so what do you suggest for the bulk substrate, then? Coco coir, which I had no success finding yet? Couldn't I just use 80% manure 20% vermiculite?

You can easily get coir from your local pet store. If it's not there, then get it off amazon! I hear the Exo terra "plantation soil" brand is the most popular these days, but just about any type of coir will work. :thumbup:

That is a great ratio to use! Make sure to add a handful or two of gypsum to add some extra nutes as well as fluffing up the sub, so the mycelium can easily colonize it.

if you plan on using 80% manure or any peat in yer bulk as stated above then it will need to be properly pasteurized or you WILL fail and IMO 80% store bought manure is way too much as its texture is garbage it would be a pile of mud.... find some coir and prep it with bucket tek at least till you figure out whats what also UTSF all your q's are easily answered good luck:thumbup:
edit:3.1 Tahoe answered correctly above but did not elaborate and I thought you might fuck this up so the only bulk sub you can safely sterilize(open air spawning) is CVG or anything straight coir or verm because these are low nutrient and lack the beneficial microbes left behind by pasteurization. so you can basically use coir however you want verm too which is why we can prep them via bucket tek which is actually partial sterilization which if done with with anything else(more nutrients) will be a contam magnet. the only way to sterilize bulk and get away with it is to spawn it in sterile conditions which isn't easy

:orly:  Manure is one of the best substrates to use. Just make sure you squeeze to proper field capacity and it's ready to be loaded up into jars and pasteurized.

Millet is cool look: "how foo prepares his grains" or something like that

Also look for coco peat in agriculture stores its the same as coco coir.

manure is great its just that ALL the store bought bagged manure ive used (3 diff kinds) has had garbage consistency:shrug: I use a quart or two at a time for a nice supplement for a mono(properly pasteurized) although ive had good results with it a I failed the first few times. the shit just turns to mud :shrug: so it needs something in it to fluff it up. but this kid has no clue to what hes doing so IMO its recommending failure to tell him 80% store bought manure is gonna work when he has no idea what a good bulk mix looks/feels like bet hes gonna end up with a mud pie

Never used store bought manure. I get my hpoo from ebay :lol:. Dried and aged hpoo, 15 lbs for 22$, not a bad deal at all.

And additives such as coffee, don't really boost up fruit production by a noticeable amount. Its best to skip it and stick to the basics, especially for the first time. What really matters, is the strength of the culture you're using (genetics) and how clean the spawn is (you must always practice proper sterile techniques in your SAB).

I have never seen store bought manure that was good for growing mushrooms. But that doesn't mean that is not it there

I think your best bet would be using coir and verm prepped like this https://www.shroomery.org/10858/How-to-do-Coir CVG (even without gypsum) is the easiest bulk sub recipe and is very hard to mess up for your first grow id recommend skipping the additives (ie:coffee,poo)because you will have to properly pasteurize not with the bucket like in the link above. don't get me wrong OP additives are great you just need to get a few grows under your belt before you get into more advanced methods.
Tahoe,Psilo yea store bought manure is pre composted so it comes like dirt very fine dirt.. I find it hard to prep because theres a super critical fine line between perfect hydration and mud I mix it in bulk subs on the regular but only in 1 qt amounts its kinda like prepping worm castings I guess where you like have to mix it in to get a good fluffy sub I find that chopped straw works about the best for keeping it light when using this stuff. the best thing about store manure is its cheap AF 1-2$ a bag so try if your looking for a cheap additive :shrug:
