sometimes when bags and jars I’ve made with a high percentage of sawdust, I’ve noticed that the mycelium doesn’t get as fully white as other bags.
I’m wondering, are these still fully colonized, and ready to fruit?
I was having a bit of trouble capturing a good photo of this.
But here is an example of a bag that is fully white:
And here is an example of a bag where mycelium is all over the bag, but seemingly less dense/white:
Also in the photos below, comparing a bag spawned with 50% sawdust and 50% coffee vs a bag with 90% sawdust and 10% coffee, the 50-50 bag appears much more white than than the 90-10 bag. But they were inoculated one day apart, so maybe this is just “as far as” I should expect the sawdust bag to go?
We also tried a few sawdust jars one time which seem to have stayed in this sort of “stalled out” state for a long time, which makes me wonder if there aren’t enough nutrients that the mycelium needs if eventually it just stops growing in the substrate and doesn’t become as dense as in a more nutrient rich substrate. have others also observed this?
