The whole thing on purity and alchemical values is very confusing to me.
However, it seems that purity is more than just some min/max thing, and I should get into that matter.
So, I am currently setting up my hermit farm, as in the farming guide sugested I've created 4*4 fields that I will be splitting into the 4 elements, giving me 4 fields per element.
As I've understood I'd need 4 compost bins one for each element, to get that I'd have to grow trees for each element, remake a new compost bin rince and repeat.

Plus, I could get some worms (are pythons better or is there no difference between those two?) and feed them good element food to increase the outcome a tiny bit more...
Is all of this even worth it?

At the end of the day all I really want/need is to have decent food (mainly phlegm and bb) to be able to do other stuff around my camp. (and some gluttony)
Currently I use mushrooms, but I don't want to run around searching mushrooms anymore.
