Whats the test you're trying to perform and what information are you trying to gain?

What species do you plan on growing?

Is this going to be a pf/bottle grow or are those meant to be bulk substrates?

Suggestions can't come if we have no idea what you're trying to do with all this

That's fair, right now I have Golden Teacher, JMF, and Tosohatchee. Was wondering what would be the best for what.
Along with, how do you store substrates? Is that even possible?
And just general strain recs, sorry I wrote that in a rush

^ what boxtrotalpha said

Hi Cube. Addressing the Golden Teacher grow…

If you haven’t seen the HHG, it’s a great read. Link in my sig. it covers making spawn and substrate

On the substrate, current tek for cubes is to just use coir. You don’t want nutrients in the substrate

Storing, just don’t hydrate and coir keeps forever. If you do, the hydrated coir seems to keep in sealed buckets for quite a while. I’m not sold on that and I’m starting to make fresh for each tub. Ymmv

I looked at your pics.  I’m not sure what’s up. Just practicing?

It’s a little confusing. If your doing bulk grows you would be spawning your grain “spawn” to inert substrate. If your doing PF tek you would be inoculating a nutrient media that’s like a hybrid of substrate and spawn… sort of.
The best substrates for bulk are inert, lacking almost any nutrient, such as coco coir, coco coir and vermiculite, pasturized manure with a blend of coco coir and vermiculite, or pasturized and ph adjusted peat. Really though your best substrate will be coco coir.
PF tek uses brown rice flour and vermiculite to make cakes in jars which you inoculate with a spore solution or liquid culture, then birth the cakes, when fully colonized, into a fruiting chamber and the fruits grow right from the cakes.
Both methods are super simple and very beginner friendly.

How does your spawn made from rolled oats and flour look? That’s a pretty dense media that would be hard to break up and would likely be anaerobic a little ways inside. Though I’ve been out of touch for a few months so maybe this is a new trend, but even oat groats and whole rice seem like really finicky grains to use. Lots of other user friendly stuff out there.
All the “substrates” you mention seem like very bad choices.

You definitely need to read through the Hitchikers guide.

Most actives get all of their nutrition from the grain spawn.

The Substrate they get spawned to provides absolutely no nutrition, ONLY WATER. Hence, plain Coco coir is all you need for substrate for most any active, other than the exotics like wood lovers and Poo lovers like Pan Cyans
