I use this media bottle because of a recommendation from here. The pour is like magic. Very precise. I like this shape better for pouring because my SAB is small. 250ml is good for like 5 myco-quarts++...
I also like the clarity of the bottle for the needed sight, the measurment, and it being pressurc oookable all in one

You Can PC it, just keep the bottle lid from sealing 100%. You can feel it when tightening. It will be fine sealed too but safety first, it wont melt. Use foil on top so that you can equalize pressure in the bottle after PC.
Outline:
Make grain soak/boil water your base with agar powder. Make it like you're going to pour agar but 1/3rd - 1/2 the amount of agar. I added a small amount of light malt extract as well. Its agar, do what you want.
Let it cool, be patient.
Take a very tiny piece of mycelium off of an agar plate, it can be 1st or 2nd transfer from germination preferably. drop it in and tighten lid. Temperature shouldn't be too warm for this or it may sink and make the next step hard.
Let it grow on top, be very gentle and do not shake. Watch for contams, its still 2D surface.
Give it a day or two to stretch out a little and shake. Shake it hard, don't be a bitch. Give it bubbles.
The bubbles are suspended inside the agar bottle along with a huge amount of microscopic growing mycelium. The surface of the agar is now hundreds of little spheres and growth is RAPID.
You will be able to pour soon. you'll see how much growth you have if you hold it to the light after sitting a long time and settling the bubbles.
If you shake it a day or two after the first shake, your growth is exponential.
Great! So a fast-colonizing innoculant with a sterility test built-in. It could be possible to shoot or drop a tiny amount of spores in and germinate like this too. Just keep your eye out for contams longer(you will anyway because germination is slow).
There is utility to this.
The agar is mostly water, it liquefies but also stays suspended throughout the grain jar. This prevents pooling after using a large amount of the bubble slush. It also re-hydrates your grains, allowing you to keep your grains on the drier side when prepping your grain jars. helps to keep bacteria down and prevent waterlogging.
Using more IS better. You're spreading around buoyant water-filled agar slush(slushier is better than lumpy) saturated with happy already growing mycelium. It itself is useful to your spawn as food and water.
Shake it hard. Don't be a bitch.
This can take you from syringe to grains in one step, feed and hydrate your spawn, and make colonization time a week. I didn't wait more than a week after transfer before I poured the slush to grains. It was more than enough already.
Really fast innoculant/grain colonization, or spore germ to unlimited grain jars(g2g or use less innoculant each).
A T0 liquid culture parent is pretty neat. Might take a couple tries though.
