YoshiTrainer's guide to low-prep grains * 54
    #28052502 - 11/15/22 10:35 AM (1 year, 2 months ago)

Below is a chart I put together for low prep methods for various grains. To me, soaking, boiling, draining and drying are all a waste of time. For the most part, I measure my grains, add water, then lid/foil and into the PC. For a lot of these grains, it is that simple, for others, a little extra care is needed. These #s are what work for me, you might need small adjustments for your materials. I will also add, smaller jars are more carefree than larger. Edit: when you bring your PC to temperature,  use a medium+ heat, this may help reduce burst grains The values below are grain:water.

Grain        1/4 Pint                Quart              Lb

Millet        2Tbsp:1Tbsp      1 1/3C:158ml
   
Milo          2Tbsp:21ml      1 1/3C:210ml

Oats          2Tbsp:17ml      1 1/3C:175ml

Pearled barley 25g:15ml                                1lb:270ml

Rye            2Tbsp:22ml      1 1/3C:230ml

RGS            2Tbsp:13ml      1 1/3C:150ml

Wheat          2Tbsp:22ml      1 1/3C:240ml

WBR            25g:17ml                                1lb:275ml

WBS            2Tbsp:16ml      1 1/3C:165ml

Millet: a great choice for no prep, cheap and easy to work with. It is 2:1 seed:water by volume.

Milo: Kind of a pain to work with but seems to be good for spawn and great for drying later.

Oats: Many love or hate these grains. They are easy to work with, a good price and work really well for hearty spawn.

Pearled barley: I added this one mostly for edible mycelium TEKs, should be done in bags.

Rye: Another great choice, it is easy to work with,  just grain + water.

RGS: Surprisingly easy to work with, measure  it is a heavy 2 to a light 1 seed:water ratio by volume. I use RGS for high spawn rate with low nutrition.

Wheat: Another classic, a little sticky and hard to shake though. Not the best for big jars but great in bags.t

Whole Brown Rice (WBR): Another grain I use mostly for edible mycelium TEK. Should use bags for this one.

Wild Bird Seed (WBS): I've warmed up to WBS alot lately. Give it a whack on the lid to get the grain puck loose then a good shake.

Rinsing:  For grains that need rinsing, you  need cold water, a scale and a strainer. For single jars, add your grains to the jar, place jar on scale and rezero your scale. Keep the scale "awake" while you rinse your grains. Put your jar back on the rezeroed scale and add your water (1ml=1g).

You could also find the weight of your grains + jar and add water weight. Rinse with cold water to your heart's content, drain, don't worry about drying. I have a small mesh strainer the fits inside the jars mouth to drain with. Reweigh your jar and top with water til you reach your right weight (jar + dried grain weight + water weight). As an example, if your jar and dry grains weigh 550g and you are adding 200ml water (200g), your jar should weigh 750g after rinsing/draining then topping off.  If you normally make multiple jars, consider with the first round weighing them all and taking the average. Just use that average for this and the next runs.



Some final thoughts, no prep will save you tons of time and effort. The grains will not come out evenly hydrated, some will be drier, a few will have burst, some even leave a film in the jar,  it is all fine. Of the grains tested, millet, oats, rye and RGS were the easiest to work with then WBS, milo and wheat. Also, maybe anecdotal but grain mixes, seem to work better, two I use a lot are:

I start most of my agar on this grain mix, in  a quarter pint jar, add

1 Tbsp oats
1 Tbsp rye
19ml water

PC 90min @15psi

Here it was dumped on MS Starry Night agar



I G2G the quarter pints to these pints then use them to bulk or you could G2G to quarts.

In a pint
2 Tbsp oats
2 Tbsp rye
2 Tbsp millet
2 Tbsp RGS
66ml water

PC 90 min @ 15 psi



With MS Starry Night



I hope you will try a jar of no prep your next PC cycle and let me know how it works out.

Cheers!

Some conversions

1 1/3 C = 315.45ml
2 Tbsp = 29.57 ml
1 lb = 454.59 g

Yeah i think grain prep is a wast of time also, i use this for wheat,and rye


Nobody does it like me
1 cup wheat
1 cup water
1cup vermiculite

Cook in mushroom grow bags for an hour and a half 15 psi ,let cool and inoculate in front of flowhood
After bags are fully colonized i put in greenhouse
enjoy mushrooms

No grain prep no soaking no extra steps other than what I’ve said

Close bags up like this before you cook and leave them like this to colonize


My martha set up
Light on 24/7
80Β°
Humidity on for 15 minutes off for 1/2 hour



Some of my all wheat grows

Milkboy, I ran a QT of wheat last night and let it cool completely in the PC. My dial read 17-18 psi for 90min. I'll takes more pics tonight.

Thanks yoshi I’ll try out some no prep bags when I’m back home and report back!

Milkboy, have you ever thought of throwing some vermiculite into the jars before hand? Just a thought but it might help with the clumps. You might have to adjust water ratio though

These are the 4 jars I did up 2 1/2 weeks ago. This is a little under 3 days after the second shake and they seem to be doing pretty well I think. Most of the bigger clumps seem to have broken up fairly well too. Think I'm gonna do 1:3 on these to see how they go, the 1:2 I've been doing hasn't worked out quite as good as I hoped so guess I'll find out.

2 are from 1 plate pin and 2 are from another plate pin I grew out on agar so I'm hoping for a decent canopy in the two SBs.



I have 2 other jars I no prepped of red millet I threw a whole plate pin in each and those are looking good too, so far I'm really liking this grain prep method. Super quick and easy working very well so far.

Hi Yoshi, I have used this method with success, thank you for posting it. The jars colonize and I haven't had any contamination, but there is one issue, the rye grains get very sticky and clump up, the only way to get them out of the jar when fully colonized is to cut up the mycelium with a knife. Any tips on how to stop it from being sticky? I do shake them after PCing, when they cooled down enough that I can touch them. But they still clump up strongly in the end and won't release easily from shaking. I don't want to bash the glass jars too hard because they might break. Later I will get millet as I heard they are better for this method, but for now I have tons of rye to work through.

Cleaned up your chart a little. If you use code blocks, it'll use a monospace font and things will line up:

Code:

Grain 1/4 Pint Pint Lb

Millet 2Tbsp:1Tbsp 1 1/3C:160ml

Milo 2Tbsp:20ml 1 1/3C:200ml

Oats 2Tbsp:17ml 1 1/3C:175ml

Pearled barley 25g:15ml 1lb:270ml

Rye 2Tbsp:21ml 1 1/3C:210ml

RGS 2Tbsp:13ml 1 1/3C:150ml

Wheat 2Tbsp:22ml 1 1/3C:220ml

WBR 25g:17ml 1lb:275ml

WBS 2Tbsp:16ml 1 1/3C:165ml



Might try this to use up the oats I have left. I would be doing them for 2.5 hours because it seems they're always bacterial. For quart jars: 0.75 quarts / 1.333 cups = 2.25, so I assume I'd add 175 * 2.25 = 393 mL water?

I like how they turned out. I was eating dinner with my in-laws so they sat in the pressure cooker longer than I would have liked. I also suck at following directions so I didn't weigh anything before I rinsed. The bottom grains were a little bit of a puck, but I got it broken up. I am going to say it was mostly operator error. Here is one of the jars. I will update with how colonization goes.

Went pretty well I'd say! Used one and a half cup (my cup size isn't standard) and 200ml of water for a single quart. I'd say it's kind of on the dry side but you know how it is - we'll see tomorrow when it's cooled down if that's actually the case. There's some gunk on the bottom that's pretty stuck but I mean hey it's probably sterile and nutritious as hell. :stoned:

I've also added a single teaspoon of coffee to go with the teaspoon of gypsum because I'm a "I soak and simmer my grains in coffee and gypsum because I grow stones and stonesun told me so in his original guide which I've never been able to let go"-guy. Don't @ me :mad2:

All-in-all I call it a win.

Thanks Yoshi! :heart:

An update on these guys, 3 bags of low-prep grains left without inoculation and stored for a year. All look fine, no contam, the cracked corn in the WBS is a little mushy though.

good stuff Yoshi :rockon:

Will give some of this a try for sure on the next grain order, always been shy to do no prep but you convinced me to give it a go now
