Agar agar is an extract from a seaweed used to solidify media. In mushroom cultivation it is used to make a medium beneficial to mycelium growth in an enlosed round flat dish, called the petri dish.
This petri dish can be either inoculated with spores or a small piece of a mushroom
tissure or mycelium can be transfered to it.
Amature mycologists may want to try their hand at using agar but are put off due to the fact that they would require a pressure cooker, glovebox or flowhood for doing sterile work.
