Speed of colonization: the advantages of dunking colonized grain (agar pictures) 1

So I took a bag of grains that had been colonized with an isolate.
I removed one grain before dunking the rest.
I also took a dunked grain of the same size.
I put the two on agar to see just how much the mycelium benefits from being rehydrated before spawning to bulk.
Here is the timeline, today I realized this would be a good thread of its own:
8/27 (24 hours after being placed on the dish):

8/29

8/30

8/31
Here is the not-dunked side vs dunked:
9/1


I know which one I want mixed into my substrate

Results you can't argue against. Awesome Frank.

I started dunking my grains about a month ago and the results have been very pleasing.

Let us know if you see a difference in actual colonization times with your subs, but from this alone I'm dunking for myself to try it
Edit
Colonization times for bulk substrate decrease, sometimes by as much as 50%+. Fruits are thicker and healthier. Yields are improved. -FH
Well that answers my question

I just dunked my grains and used the water to get my compost, which was a bit dry, to field capacity. Do you think using the dunk water will aid colonization?

Dunk water + agar ? nutritious enough?

Those are great results! Im dunking for sure now. But just to be scientific about can you repeat it a couple times?
I noticed that the myc differences look like the difference in my two MS bags of PE. Maybe one is less hydrated? I got them mail order.
I did see you used an isolate. But I have read there can be multiple varieties if its an isolate from MS.

I'm not sure I follow.
This is an isolate, there is no "variety" whatsoever. It is a single sector, one of about 50 isolates I keep in slants.
It doesn't really get more controlled than this 
If you are using MS, you can expect everything to look different every time, from mycelium to fruits.

It sure as hell won't hurt to try 
Pasteurize it properly before you spawn to it.

This would be a question for my agar journal or the grain dunk thread

Hopefully it was still okay from the last time I used it, about a month ago. Bought 10lbs from a sponsor and kept it sealed in a bag inside the fridge. Crossing my fingers.

This about settles it for me 
Maybe I'll do this with some other species as well.

Since dunking isn't done with sterile procedure, is it a contam risk to use dunked grain for my future agar projects? It seems you pulled it off and that growth is impressive. I've always used non-dunked grains for agar while doing g2g.

Are you asking if you can take a grain from your drained spawn jar and put it to agar without much sterile procedure?
Yes, you can, it's very easy.
The mycelium is recovering so fast it will outrun any contams. The dunked grain even rolled around a bit on the petri dish, but it colonized before anything else had a chance.
I wear gloves and take a clean, unopened ziplock bag.
I take the piece(s) of grain out of the pile and put it into the bag.
I seal the bag quickly and spawn the tub.
Then I go to my "lab" with the ziplock, wipe down my gloves, put on tyvek sleeves, and transfer the grain(s) by hand to the petri dish(es).
You will get some really aggressive growth. Make sure to take at least one transfer before using it to inoculate more grains.

So if one was to use quart jars for a bulk spawn, would you just fill the fully colonized jar up and leave it overnight. Drain and spoon out the grain into the bulk substrate?
Edit: Nvm found the link with the info I needed. I will be using this method next go around.

The process is described in detail here:

FrankHorrigan said: How to do it the quick way:
I take a roll of fiberglass screen (the kind used in window screens) and cut a piece to fit around the top of a five gallon bucket.
Grab the five gallon bucket and clean it out.
Break up your spawn jars and give each a good smell to make sure it is clean.
Dump the contents of each clean jar into the bucket and fill with enough cold water (not distilled) to cover the grains.

Attach the house screen with a rubber band and let it soak for 10 to 20 minutes.

When the time is up, secure the screen with your hand around the edges and tilt until the water pours out. It will drain very quickly, tapering down to a small stream after 10-20 seconds.

How to do it the other way:
Fill each jar with cold water (not distilled). Let it soak for 10 to 20 minutes.
Drain by placing the lid over the top and leaving a gap between the lip of the jar and your lid. Drain it well. The grains will be quite wet at this point.

Hope this helps

sweet want to try this out with a isolate i have from a good ol' friend of mine.
would the mycelium ever weaken or degrade after so many transfers?
