So im still new, so all help is needed! but right now im wondering what is this item I just got via exploring: Scheme: Hops golem. Does it do something if I use it? im afraid of using it and wasting it or something, in case it holds any value...

Schemes and blueprints let you build things, under Craft and Construction.

Golems take X amount of a substance, eg 30 cotton, then double it over six days. Giving you 60 cotton.

I'm not sure how much hops you need but the same concept applies.
