Yes. I mentioned in another post that I have come across a source

and
have
ordered some.

Must've missed that.. Y can still ahve fun making you're own if you
wish though.. Try Agar and up to 5% V8 carrot juice.. As long as it
starts off sterile (eg clean heat cleaned containers) and is set hot
then cooled) there is no reason why it might not work OK..


Where does one buy Agar?
What does it cost?
What is wrong with simply making up a weak jelly with ordinary "food"

jelly?

[...]

Wholefood shops sell Carragheen or Irish moss: I don't imagine it
costs much. I've always meant to try making the pudding, but have
never got round to it.

I have no idea if you can use gelatin for propagation; but I think the
reason it isn't used in labs is that it has a lower melting-point than
agar.


I have my doubts if this is important. After all, I propose to root the
cuttings at a temperature at which the jelly will be stiff.

There may also be an issue in terms of reactivity to acids,
perhaps?


You may have something here.
I will have a shot at using jelly, but not until after I have played with
the commercial gel
