Seeds Quality.

[Wolgirt]

I am playing for about 4 months and I have a question about the quality of the seeds.
In the Ring of Brodgar says: Farming limits: seeds when harvested (MaxQuality = farming +5)
I have 190 farming + 120 from some items = 310, but the seed I have at level 160 does not increase when I harvest!
Is there another way to raise seed levels?

When you plant a crop, it receives a quality change between -2 to +5, assuming farming doesn't cap. The quality change amount is the same for all crops of the same type, in the general area (minimap or two?), planted within a similar time-frame.

If you want to know specific bounds, one of the devs stated that it took about 500 tiles in any direction or about 8 hours to get a fully random number for the quality change. Small changes, a dozen tiles, 10 minutes, would only add in small variances, -1 to +1. For my small farm (<100x100 total area for all crops), that's the biggest variance I've seen for any one plant.

Sprouting barley on a herbalist table can increase the q if you have a good q table.

Slow grind for most everything else though. This late in the world you can probably find 600-800q+ seeds in abandoned bases.
