YoshiTrainer's guide to low-prep grains 54

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

good stuff Yoshi 
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

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 Iβve 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

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.

just in case anyone else here uses alpiste ive been running no-prep experiments and the best ratio seems to be 400g seed to 130g water

Cool write up Yoshi, I've got some millet I'm itching to try with some LC that is looking really nice.
For the pint jars is PC 90min @15psi good or should it maybe go 2 hours?

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.

Sounds good. I need to test the LC on some agar and I'll report back in a week or two.
Thanks for the quick reply.
