Still putting together my powerpoint....
But for now, here is my easy agar recipe
1 teaspoon of agar
1 teaspoon of malted milo
250mL of water (or coffee)
Mix agar into boiling water, simmer and stir until dissolved, add milo.
Then pressure cook the mix in a bottle, covered with foil, for 15 minutes at 15psi.
You can add 1-2mL of hydrogen peroxide when the temperature of the agar is between 50 and 60 degrees C.
Pour into petri dish/jam jar etc., allow to cool, then add mycelium.
For grain spawn, choose a grain (can be mixed bird seed), and cook.
For wheat grain, I soak for 24 hours after a rinse, then drain and cover in boiled water, bring back to the boil for 5 minutes, then drain.
Now your grain should have the consistency of just cooked brown rice-not mushy, but if you squeeze a grain between your fingers, it should squish.
Load into jars/bags/polypropylene tubs and pressure cook for 2 hours at 15 psi.
Allow to cool, then add some colonised agar.
Once your grain spawn has colonised, you can use it to spawn more grain, or add to a bulk substrate.
For the sawdust blocks, just add boiled water.
You can also add between 50 and 200gms of a supplement, like rolled oats, but you will need to Pressure cook the mix once you add the supplement.
Hope that helps for now.
