To start this off, this is based on the current limit of THREE pods in the whole game right now. Each pod can only take 6 modules, which means there's currently only 18 modules that can grow any of the 43 possible farming options right now.
We need more.
My idea is that there should be a "dynamic" system, sort of like what happens with Ixion's capsules, where someone can rent a pod at the usual rate (1k/week) for access to a racked pod. Everyone would be limited to one pod, but more people would get access and create a wider array of material growth.
