Finding perfect mix for bulk bags.
    #20270834 - 07/14/14 11:44 AM (10 years, 6 months ago)

Hey everybody! This is my first post.

So, I'm about to mix a substrate and sterilize some bulk autoclave bags... I will be spawning from BRF cakes.  With that being said, I have some ingredients and I'm looking for some suggestions for creating a great mix that'll make my cubes happy.

At my disposal I have:
Peat Moss
Humus Soil
Vermiculite
Gypsum
Hydrated Lime
Water
Straw (chopped to 1" - 4" pieces)
BRF

What do you ladies gents think? I plan on mixing the ingredients, loading bags, heat sealing, PC'ing, cooling, then spawning ~3 cakes per bag . . .

Thank you.  Have a great day.

Go pick up some coco coir and mix that with the verm.

Also you don't want to sterilize bulk sub, you only want to pasteurize it. Sterilization is only for spawn.

Hey!

I've had some good luck with sterilizing the bags, then adding the cakes.  How would you suggest I pasteurize the final mix in my big ass AA pressure cooker? :confused:

Also, all I have is those ingredients . . . what's a good recipe with those ingredients?

You can sterilize it but if you do you'd want to spawn it infront of a flowhood or in a SAB.

You pasteurize in jars; look up franks proper pasteurization:thumbup:

The only bulk sub you have listed is straw and I would personally prefer to use coir or manure over that:shrug:

Cool, man.  Thanks.

So, straw and hydrated lime?... pasteurized and stuffed into some poly tubing?

From your response, I just started soaking some rye berries... I'll spawn from them instead of BRF.

Have a great day.

Coir is cheap and is a bit more forgiving than straw. You can find it at any pet store, it's used for reptile bedding. If straw is the route you wanna take though then go for it.

Good choice on the rye:super: Grain spawn is the way to go.

I found some Coir... 50/50 with verm?  Should I add any Gypsum or CaCO3?

Make it more like 80/20...not many people use a 50/50 mixture.....and you can add some gypsum if you like...no CaCO3.

Thanks... 80 coir, right?

Then hydrate to field capacity . . .

Don't they need some food? Or will they rye or BRF cakes be enough?

Yes, then pasteurize.

The coir is "food"......but a majority of the nutrients come from the spawn(BRF or grains).

OP, are u doing an in vitro thing where u colonize IN the bag, or are u just prepping the mix to spawn in a tray or tub?

Blindingleaf:

I'm colonizing in the bags . . . I've had success in the past, once the bags are fully colonized, to then cut the bags off and place them inside my greenhouse and fruit.

I'd love to develop a tray system for my greenhouse, but it seems like I should get *really* good at one method before moving on to the next.  I could experiment on a small scale on the side, eh? . . . there's a lot of monotub methods I've seen, but what I'd like to use are shallow trays that I can slide onto the metal shelves of the greenhouse. Simply because I've got quite a good thing going with the greenhouse and don't want to start monotubbin' all over my basement floor. :thumbup:

Since you're sterilizing, I'd do coir/verm/straw/gypsum/lime. 50/20/20/5/5.

Sterilizing your bulk substrate is fine if (and only if) you keep it sterile the entire time. Commercial farms regularly do this. You'll have to spawn in front of your hood or in your SAB. If you don't wanna do all that, pasteurize it.

Trays are a step backward from what you're asking about BTW. I'm looking to eventually upgrade to fruiting from the bag like you're talking about.

Awesome, man!  Thanks for the input. Alright, cool, then I'm on the right path with the bags then (had some very nice harvests--4 flushes) . . . I've had some good luck in the past with a mix of coir, vermiculite, humus, water, gypsum, spent coffee grounds, and some straw. Now I'll definitely add the CaCO3. I was definitely searching for affirmation here on the shroomery forum.

[ASIDE: When I made the bags without straw, they tended to crumble when put into the greenhouse even after 100% colonization. So I added straw, and the straw acted like a structure that bound the ingredients together.]

I didn't realize it would be a step backward to go to trays . . . Stamets book, blah blah blah.
Although, I'm suuuper interested in Roger Rabbit's straw logs because of the reduced cost of materials (minus poly tubing ~$120) and how "easy" and beautifully they would fit right on the shelves of their greenhouse.

EDIT: I'm nervous to pasteurize . . . wonder if I can do it in the huge A.A. PC I have.  Otherwise, I learned to seal the mycobags with the ribbon sealer before they get PC'd, so when I take them out and into the SAB I then cut them and introduce spawn. :thumbup:

You shouldn't pre-seal your mycobags. They can blow up, even if they say they're designed for it. You don't wanna clean that mess up. Check out RR's videos, look at how he does it with Tyvek sleeves.

You can absolutely pasteurize in your PC. Check out FrankHorrigan's link. But I would really sterilize them if you've got a big enough SAB or hood to inoculate them in. It just ends up being easier IME.

Also leave out the humus and coffee. Humus just doesn't do anything but close up your substrate, and coffee is very acidic and can cause contam problems if not carefully pH balanced. If you're still in the process of figuring out how to pasteurize and such, you don't wanna add that extra bullshit.

Sounds good.  I'm new here, so if you have time, would you mind sending me links to RR's tyvek video (aka bag-no-splode), and FH's PC pasteurizing?

Hmmm . . . I'm very intrigued about this pasteurizing thing now . . . before this, I've always worked in a cramped SAB (which is a pain).  So the procedure following pasteurization would be something like:

1. Wait for PC to cool
2. Shake-n-breakup rye jars
3. Open PC
4. Open a mycobag
5. Dump 3-4 jars into mycobag
6. Ribbon seal mycobag
7. Repeat 4 - 6
8. incubate (that rhymes)

And all this can be done in the open air? (My clean basement)

PS: I have a 2' x 4' industrial HEPA . . . wayyy to big, because I'll need something like a 1200 cfm fan according to Stamet's calculations.  (I'll get one eventually. I found a workaround for building a box he he heeee :wink: )

Why lime? is it because the straw is acid? I never donne straw before...

I ran some bags with coir/verm/gypsum/black kow , I sterilized the 4-5qts and dumped 1.5qts of spawn in front of a flow hood.
Pink Buffalo






I sterilize everything though, don't care much for just pasteurizing anything, even though most people have great success with it (hell I may have even used the roast pan oven pasteurizing tek before loading it into bags to pc, probably over kill, but I don't have many contams and I'd like to keep it that way lol)

No. Use the search engine. You'll end up learning more that way.

Search and read. You can't spawn sterile substrates in open air.
