What is a Spawn to Substrate Ratio?

Spawn to substrate ratio refers to the proportion of mushroom spawn (the mycelium of the mushroom) to the substrate (the material the mycelium consumes) in mushroom cultivation. This ratio is crucial as it affects the speed of colonization, the yield of mushrooms, and the potential for contamination. A higher spawn to substrate ratio means faster colonization but can be more expensive, while a lower ratio is cheaper but takes longer and has a higher risk of contamination.
