[MERGED PR] Makes botany chem production scaling have diminishing returns

[Jimbo20]

i can't think of any legitimate criticism of this other than "me no like botany nerf"
other than it being less of an unlimited chem factory (which seems it could mostly be solved with just a lot of high yield and fast growth), i think this is mostly a nerf to tomato floods + seethers - seethers i guess they kind of had it coming...
you're gonna come for my rainbow melons next *shakes fist*
