The Purple Mystic AIO is at the "any day now" stage. Hard to see through the bag, so until the shrooms reach a discernable size, it's a tough call on when to begin FAE. Personally I think sooner is better so I think tomorrow I'll make the second notch at top-right and start FAE. I've installed duct tape tabs on the front and back of the bag so I can make like an accordian to billow air in and out.
The Blue Meanie Cubes grain is fully colonized now and just getting denser, so I think tomorrow will be a good time to mix the grain with the substrate. I'm using the compost+CVG type of substrate for additional nutrients, so the grain needs to be thoroughly mixed to get the maximum number of inoculation points in the dung-bearing substrate. Literature says casing layer is optional so not going to bother.
The Purple Mystic- X-periment is recolonizing at an amazing rate! There was a lot of mycelium and I mixed it until my arms got sore, so it looks like the effort paid off. 5 days until the substrate arrives- the grain will be a solid block by then!
