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!

That is cool 99.99 and some sweet pics!
You could probably get away with using milo or oats too w/out any changes to your recipe.

Thank you guys, I'm hopeful to hear some reports come in about how it works for others.
@Bajazly, I do up to quart size jars for 90 min @15 psi with no problems.

Thank you guys!
SDO, that'd be awesome to cut back your workload like that! On the occasions I've done large bags of grain, it seems like they used a little less water than jars. Plus if you use heavy amounts of LC, maybe cut back your hydration water just a few ml?
Good luck!

Good luck Milkboy, shake them hot if you can, it makes life MUCH easier!
Suckatshrooms, I did volume measurements because they are much faster, especially if you are doing multiple jars. Near the bottom of the post, before all the pictures, I put metric conversions for volume. Good luck!
Some conversions
1 1/3 C = 236.59 ml 2 Tbsp = 29.57 ml 1 lb = 454.59 g

I'm sorry to hear that Milkboy, I do get some burst grains but not a solid layer of them. Maybe cut back 5ml of water for your materials? If the wheat was really dirty, you could try rinsing it first. Hopefully your jars will colonize fine and you wont be disuaded from trying no-prep again.
Good luck!

Hello BirkenSaft,
Pint jar = 473ml Quart jar = 946ml
For a pint jar add 2/3C rye = 160ml and 100ml water
For quart jar add 1 1/3C rye = 320ml and 200ml water.
Good luck!

milkboy said: Well half of them I did rinse so I dont think it was that, no worries will try again in a few days.
I wonder if heating of the PC makes a difference? I usually put mine a little over medium to bring to boil. I used to get cracked jars on occasion and this was my remedy. Maybe a slower rate to boil might allow the grains to absorb water better, kind of like a mini boil? Did you use gypsum?
Thank you again for your input Milkboy, your data will help get the kinks out!

Hmmmm interesting, maybe it is the heating? None of the grains I've run ended like that.
Edit: I used red and it looks like you used white wheat but I don't think that makes a difference.
Edit#2: With wheat, id guess you wouldnt need to rinse, unless you noticed a lot of chaff or other debris with your last batch.

Well poop, I'm sorry to hear that Milkboy! I made some wheat pints for tonight, in solidarity with you. I also made a couple oat jars for nostalgia. I'll get pics later, I'll also grab a pic of my wheat for comparison.
Thank you for trying again.

Hello Mind.at.large, so far I've only done up to 3 pound bags. They seem do fine but use slightly less water.
Milkboy, I tell you hwhat. You might not know this but sometimes I am a complete dumbass! Did you try hot shaking your wheat jars? Your first jars were the right ratio just needed a thorough shake. I made some pints and allowed them to completely cool in the PC w/out shaking. Though smaller jars are easier, I still had some solid pucks of grain in the bottom of the jars like you. You made it right the first time! 
To be honest I hadn't taken pictures of the bottoms of my jars but they do look like yours. I was able to break up the cold grains with shaking but it did take effort. There was a mix of hydration levels with the grains and a film on the inside of the jar but that is all fine. I G2G from 1/4 pints and shook again. I did 3 jars of wheat and 2 of oats. BTW, Oats were much easier to shake.
WHEAT


OATS

Thank you for trying Milkboy, I really appreciate your effort!!! Maybe just try 1 jar so you dont waste anymore time or materials. I don't think 150ml is going to work any better but I hope I am wrong, good luck! I don't think it is a difference in grains either. Here are some wheat pics, BTW 1 1/3C of wheat weighed 268g.

Before the PC
Wheat
Oats

It is weird they did not break up when you gave them the hot shake. I wonder if a tsp of gypsum would help, it does wonders for WBS. I'm no Hulk but I did manage to break up the pucks of cold grains with some effort.
Thank you again!
I may have to run a couple wheat quarts next!

Thank you again for trying Milkboy, i do appreciate your efforts!
I smack them on the lids to get the grain puck off the bottom of the jar before I try ye ol' shake and break. Maybe?
If not, I'm at a loss and this will haunt me til my dying day.....

I know nothing of your shaking abilities. Though he has good technique, I don't think this guy could break up the grains. 😀

Do you have a magnet or coins on your PC rocker? Next run for me will be another quart of wheat!

Did you do jars or bags? I know this tek says to use bags but I have a lot of jars and no bags lol
SunGuy, I've done WBR and pearled barley in jars up to pint size. Because their is no husk to the grains, they want to stick, shake while hot if you can.
Thank you for your input Tedoro. I'd agree not all of the grains are properly hydrated but after the shake it doesn't seem to matter. I'd invite you to give a jar of no-prep a try, there is even a ratio for WBS.
Good luck!
