Many comments on compost threads suggest the heat in a compost pile is the mechanism which kills weed and grass seed in the pile. Many people also say their compost piles never seem to generate heat, but the seeds seem to be killed over time anyhow.

I wonder if the moisture content and the warm (not hot) temps inside a compost pile cause seed to germinate. Since no sunlight is available, the germinated seed simply dies.

Which is more important in a compost pile, generating enough heat to cook the seed or creating an environment which causes the seed to germinate?
