But your bluing is consistant across the side of the cakes, which to me indicates a problem with humidity. No lid on your terrerium? How do you keep the humidity up? Improper humidity can also cause bluing and prevent or delay pinning. You cakes look classic. Is the casing as dry as it appears?

Yes you continue misting the cakes till the first pinns appear. Make sure your humidity is in the mid 90s and you temp in the mid 70s till pinning. Then raise temp to low 80s and the humidity to low 90s.

Your cakes will recover. Good Luck.

Plus how are you keeping humidity, you have perlite, but that won't keep the entire room humid; you need to get a lid.

You should also put something on the sides of that container, I taped black (opaque) plastic to the sides, if you do that light won't hit from all directions, and when shrooms do grow they'll grow up instead of every which direction (believe me you want them to grow up). Also the lids you use will keep humidity in, but get some plastic (black) to put over the top too. The shrooms grow faster in the dark (i've found this to be true), and only need a few hours of some light (just take plastic off of top and have light in room on) cause they are phototropic.

Then I'd make sure to air out the chamber about twice a day, maybe more. I'd only mist right after you air it out, to get the humidity up quickly. Then the perlite will keep it humid.
