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