PreparationH said: It's not recommended to inoculate your grains with spores. spores/syringe may have contams. I've gotten away with it too but you're much better off germinating your spores on agar then inoculating with a wedge into your grains.
is it because of the colonization time from spore to active colony on the grain? Im guessing brown rice will take a foothold a lot quicker than on grain therefore giving the colony a better chance at life against contams? i dunno, ive always done pressure cooked grain to manure never really thought about it or had problems.

No its because spore syringes are not really clean enough to inoculate anything but cakes or agar with.
Cakes don't get shaken and agar can separate the nasty from the good. With agar you get clean mycelium for inoculation of grain
thats crazy because thats the only way ive ever done it

LC needs to be started with a clean culture. Like on agar.
A single drop of spore syringe solution can have literally millions of spores https://www.shroomery.org/forums/showflat.php/Number/21365919/fpart/all/vc/1
the chances of 1 contaminant being part of 1,000,000 cube spores is pretty high, we grow cubes out in the open in fruiting chambers. You would have to grow the shrooms in a bio-hazard clean room to get a print to be clean enough to make reliable LC with.
LC is liquid so one single contamination will and homogenize so that the entire LC will contain the contaminant microorganism.
on agar a single contaminant or two stays localized on the first dish and you can transfer clean mycelium to a new dish leaving any contamination away. this clean culture is what you need for LC work.
thats pretty cool man =D
