Hi. I'm new and have some lighting questions.

[Ms. Neon]

Hello.  I've been reading through some of the old posts trying to find answers to my questions, and I want to verify something.  During incubation the jars should be in complete darkness, but during fruiting they'll require light for a simulated day time?

Yes.
During incubation they don't necessarily need complete darkness, but they don't need any light at that stage.

Light has no little to no affect during colonization. Paul Stamets used to believe this but now disagrees. If you go to www.fungi.com you'll see Thousands of jars under 12/12 lighting. If it does pin spawn it anyways. Paul believes the pin of the mushroom will speed up fresh healthy fast live mycelium because of the hormones in it.
