72deg's 99%RH but it might be higher. 50/50 verm coir.

Those casings look fine. Humidity might be a little high, but other than that, they look great. Overlay is dead mycelium on top of the casing. What you have is healthy, rhyzomorphic growth poking through the casing layer. You should see knotting/pinning very soon. I'd also wrap those clear containers with foil to help prevent side pinning. Nice job so far.

Actually overlay is quite alive bro and continues to veg when it should be in the generative state. FYI

You're my man, Hyphae. I will always continue to back your pinning strategy, since it has helped me in so many ways. I must disagree with your statement that overlay is alive. When I get overlay, it becomes bright white and stops vegetative growth, well..., stops growth all together. Please enlighten me if I'm wrong. If you are correct (which you usually are ) then the FAQ's need to be revised. I.E.  What is "overlay" (Clickety-Click)
"The condition when the fine strands of mycelia die and become hard and matted (as compared to the light, strandy mycelia you will become familiar with.) is called stroma. Overlay is often bright white, since it has become so matted and impenetrable. Mushrooms will not grow directly from a section having stroma, as the mycelia layer is dead on top, and cannot be penetrated from below. Touching stroma (it's generally not a good idea to touch casings) - it literally feels like it is one solid piece, as compared to the much more pliant healthy mycelia."

Casing looks fine to me. Dont see any overlay.

Also, don't get overlay confused with thick mycelial "finger" growth on the casing. A lot of people get them mixed up. Personally, thick colonization of the casing surface has never presented a problem.

Not necessarily, rhizpmorphic growth is a aggressive form a mycellium.
Overlay by definition is a layer of DEAD mycellial growth on top of the casing layer that is inhibiting new mycellium to form pins.  What you have is a overgown casing.  Where the casing surface is covered in living mycellium, this can lead to overlay, but you dont have too bad of a case.

Hard overlay is when the surface myc DIES & forms a coating of dead hide over the substrate.

The mycelium blasts through 50/50 casing almost too fast, and the OVERLAY caused me a great deal of difficulty when watering and misting. Never heat the casing from above (like with a light) or circulate air forcibly over the casing. Both of these will cause the mycelium to dehydrate and DIE, and once it dies on the surface, it won't pin from under where it's healthy.

I don't know man, I'm still confused. Is overlay dead? Does it differ from complete/over colonization of the casing layer. Can it be both? There seems to be a lot of conflicting opinions out there. I wish some old hand would lend out some advice. A lot of people throw this word around, and I don't think too many of us are quite sure of the true meaning.
