What's the difference between Spawn and Substrate?
    #7290855 - 08/13/07 02:27 PM (7 years, 2 months ago)

Ok, I'm a little confused.

Since I'm playing the waiting game with my millet jars, I've been reading like a maniac. And I am confused as to what the difference between 'Spawn' and 'Substrate'. I know that colonized millet is my substrate. But one TEK was mentioning different water levels in jars, when drier, the substrate is best for Spawning, and when more wet, is more suitable for casing.

If you do a G2G transfer, is that "Spawning" to another substrate jar?

Here goes .....

Your millet could be spawn or substrate.

If you colonize your millet and then use it to colonize more millet (G2G) or if you use it to colonized HPoo or Coir/Coffee (bulk substrates) then it is 'spawn'.

If you grow straight from your originally colonized millet, cased or uncased, it would be substrate.

http://www.shroomery.org/5122/The-Shroomery-Mushroom-Glossary

Spawn - Culture of mycelium on grain, sawdust, etc., used to inoculate the final substrate, or bulk.

Substrate - Whatever you're using to grow the mushrooms on. Different varieties of mushroom like to eat different things (rice, rye grain, straw, compost, woodchips, birdseed). Different techniques involve infecting substrates with anything from spores, to chopped-up Mycelium, to blended mushroom.


So your Millet could be either Spawn or Substrate depending what you do with it.

If you use it to inoculate another substrate it is spawn.
If you fruit it will be the substrate.

Does that make sense???

Makes perfect sense. It was as I suspected.

Thanks for the link to the glossary. I had forgotten about it.

Most often you will see spawn opposed to bulk substrate, and not substrate.

The noun form of 'spawn' is the actual culture you use to inoculate your substrate.  The verb form of 'spawn' is the act of placing that culture on your final substrate.
