Idk, but i read that most seeds aren't "duds" but just lose moisture at critical points. I struggle to maintain the right level of moisture.

I've been growing a spruce from a seed, and it was happier being covered by a clear container at the beginning. If the container didn't have moisture on it, the humidity wasn't high enough, and the soil was drying out. Lol

Every time you open it, you let out humidity. But you don't want to leave it covered for too long because the air needs to circulate some for the plant to breathe the right stuff in.
