I have a question. During the colonization period you point out that as the fungi grows bigger, its growth rate begins to deteriorate because as they grow they use up more oxygen. Couldn't this problem be easily fixed by punching in additional holes? The additional holes should provide more ventilation the bigger fungi needs, thus allowing it to retain its growth rate, thereby making the entire growth time lower, and everyone likes growing good stuff in less time right?

wow this is awesome :)

"In order to illustrate the point, assume that the spore syringe has slightly 'dirty' contents but is still viable. Assume any given injection site has a 50% chance of becoming contaminated. If you inject only one site, the culture has a 50% chance of becoming contaminated. If you inject four sites, the culture has a .5 * .5 * .5 * .5 = 6%"
