Revision 4

Overview

The Grinder is a crafting station that converts harvested crops back into plantable seeds. Before unlocking it, players depend on the Happiness Seed Shop for every seed purchase, which adds up quickly as crop variety grows. The Grinder removes that bottleneck and lets farms become self-sustaining.

How to unlock

The Grinder blueprint unlocks at the Senior Farmer profession tier, the fourth of five tiers (Apprentice, Junior, Intermediate, Senior, Expert). You receive the blueprint from Graminova after completing the Senior Farmer certification quest. Once learned, the Grinder is built at a Worktable III, which itself requires advanced materials including a Mini Reactor. Both the profession rank and the upgraded worktable make this a mid-to-late game unlock.

How it works

The Grinder is a placeable station, like a Furnace or Loom. Put it on your farm, load a harvested crop into it, and it processes the crop into plantable seeds over real in-game time. The processing is not instant, and a single Grinder working through a large harvest takes a while.

The practical solution is to build several Grinders. Many players dedicate an entire shed to them so they can batch-process crops in parallel. If you are converting a full field's harvest, three or four Grinders running simultaneously keeps the wait manageable.

What you can convert

All plantable crops can be converted, including regular farmland crops, trellis crops (Cucumbers, Grapes, Tomatoes), and paddy field crops (Rice, Water Spinach). This covers the full range of seeds available from the Happiness Seed Shop and beyond.

Why it matters

Seed costs scale sharply with profession tier. Apprentice seeds like Wheat (20 Coins) are cheap, but Expert seeds like Honeyvine (720 Coins) or Star Mango are expensive enough that buying in bulk cuts into profit margins. The Grinder pays for itself quickly once you start growing higher-tier crops. Instead of spending 720 Coins per Honeyvine seed, you convert one harvest into the next planting.

It also pairs well with everlasting seeds. If you have not yet obtained everlasting versions of your best crops, the Grinder bridges the gap by keeping your supply of regular seeds flowing.

Tips

• Build multiple Grinders early after unlocking them. A single one is too slow for a productive farm.

• Dedicate a small shed or corner of your property to Grinders. Keeping them grouped makes batch processing easier.

• Prioritize converting expensive seeds first: Expert-tier crops where each seed costs hundreds of Coins.

• Do not sell your entire harvest. Set aside a portion of each crop for seed conversion so you never run out.

• The Grinder does not replace everlasting seeds, which regrow without replanting at all. Think of the Grinder as the stepping stone until you acquire everlasting versions of your best crops.
