I heard 10/1 is a good substrate to spawn ratio. The cylinder of spawn has a base with a 3" diameter and is about 3" tall inside a quart jar. How do you find the volume of a cylinder? How many cubic inches of poo/straw could I case it with?

The volume of a cyliner is the surface area of the base (a circle -- pi*r^2) multiplied by the height. You don't need that, though. You can use whatever you want -- using more spawn will make it colonize faster, though, and less time to colonize means less chance for contamination.

10:1 is a good rule of thumb, though.

EDIT: 3" diameter = 1.5" radius. Pi*r^2= 7.07 sq. inches * 3" hieght = 21.2 cubic inches.
