Similar to agar?

Here is something that may be close to agar. It so called aquafaba Is made from chickpeas. It calls for salt when cooking the chickpeas but I believe you can omit it. It hardly has any nutritional value either.
There are other legumes similar to chickpeas that can emulsify, gel, & thicken

Kuzu works as an exceptional thickener like cornstarch, but it is unprocessed and makes a stronger jell.
What about arrowroot or water hyacinth?

I've seen aquafaba used as an egg substitute in vegan whipped cream and in cocktails because it will emulsify. not positive of its potential for agar replacement but it doesnt seem capable of getting gelatinous/semisolid

Is that what is made from chick peas? If it is, I remember something about it being very salty from salt being added as the chick peas are cooking. Hopefully the salt is just added for flavor.

All I know is that it’s a resin.

There is a resin from the spruce tree that the Cree used. I believe it is what gum was originally made from.

Gum arabic wouldn't be an easy medium to make transfers with. It gels and it's nutritive enough to grow molds and maybe other fungi on its own, yeah, but it shrinks when it gels since it only does so via evaporation of water or by chemically rendering it insoluble in water like you would for intaglio printing or gum bichromate photography. Both of these processes are pretty acutely toxic to most everything and would almost definitely destroy its ability to be a growth medium through said toxicity and by not retaining water well
Agar is cheap enough that there's not really a good reason to find a replacement for it imo.

Thanks for the thorough explanation! I think some people look for alternatives due to availability. It might be cheap where you live, and it could be literally banned in other places. For example, you cannot buy Naphta or similar clean solvents to extract DMT where I'm currently at. Pickling lime is not sold anywhere either. And nobody knows what the hell food-grade gypsum is. Agar, fortunately, is available...

Aquafaba wouldn't be a good replacement for agar in my opinion. It's just that thick, starchy syrup that's in canned beans. It doesn't set in the way agar does, but if you mixed it with agar, it would probably make a good medium. It's way starchier than grain water is, and beans have a better nutrient profile.
