It must be installed on the client. Installation on the dedicated server is optional.
This release supports both sides, but the source does not require it on the server.

About this project
What does Worm Castings Expanded add?
REQUIRES PRIMITIVE SURVIVAL TO RUN CORRECTLY.
This mod adds a mechanic to an existing feature in Primitive Survival, the worm mechanic. In Primitive Survival, if enough worms are concentrated onto 1 piece of farmland, they will turn it into castings. There is a recipe added that allows the user to combine water and said worm castings to make compost, as well as compost tea, a nutrient-boosted irrigation replacement for water. It can be filled and poured out of a watering can, which is 4 times more efficient than pouring from a bucket. You can fill it from a barrel or bucket so you dont use all 10 liters of compost tea off of the ground.
The user may now stack worm castings like a firewood pile.
I recommend running this mod with Vermicomposting.
Multiplayer compatibility untested.
