Questions about setting up my Hermit farm

[wolfsspinne]

Hi there,
I have some more questions on that subject so here they go:

How much does pot-purity/water-purity/humus-purity matter? is it like 33%/33%/33%?

should one look for a clay pit as well as a lime pit or would selfmade clay work just as fine?

what would be better: 1 high element and 3 average elements (like 40/20/20/20) or 2 high elements and 2 low elements (like 40/40/10/10)?

is worm purity caped by the things I feed them on?

when focusing on one element for farming, should I look for a mine with the same element?

This one?

No. Fertilizers (dross in this case) don't affect farm output. This was removed some time ago (around the time of that post or shortly before).
