Farming and Raid Defense Guide

Plan crop rows with exact 1.0 plant values, a protected seed reserve, one defended approach, and automation sized to an 8–12 plot test row.

Tomato crop icon from Scrap Mechanic
Tomato is the value-1 baseline. Every higher crop should be compared with this unit before a visually small fruit row is added.
Water System part icon from Scrap Mechanic
A Water System removes bucket repetition, but it does not protect seeds, defend the approach, or verify that every soil plot received water.

Use the Raid Calculator for the current total and next threshold; mixed beds hide value faster than labeled single-crop rows.

Plant by Value, Not by Soil Count

Ten Oranges contribute 1000 plant-value points, the same calculator weight as one Pineapple and one thousand Tomatoes. A small fruit patch can therefore demand a stronger night than a broad starter field. Label rows by crop and record the count before watering so the Raid Calculator receives real numbers.

Protect the Recovery Layer

  • Store spare seeds away from the crop approach and away from harvested produce.
  • Keep a manual Water Bucket even after installing a Water System.
  • Place the vehicle outside the kill lane; it is transport, not disposable cover.
  • Use Metal-tier material on first-contact faces and scrap material behind it.

Build One Lit Kill Lane

  1. Walk the route from open terrain to the crop row before the warning.
  2. Block side approaches without removing the mechanic's escape path.
  3. Place hard peek cover where Tapebot shots cannot see the field center.
  4. Stage potatoes and food behind the firing position, not beside the crops.
  5. Repair the lane before replanting the next batch.

Watering Automation Is a Coverage Test

The FRM-03 watering baseline starts with 8–12 plots, one Water Container, one Water Cannon, two Pistons, a Controller, separate water and master controls, and an optional end Sensor. The number that matters is missed plots per pass. Speed increases only after a complete zero-miss cycle.

Harvest, Repair, Recalculate

  1. Clear all remaining bots and move drops out of the approach.
  2. Inspect walls, Pipes, Pistons, and storage connections.
  3. Return spare seeds only after the defense path is functional.
  4. Enter the next crop counts in the Raid Calculator.
  5. Expand one row or one automation stage—not both on the same untested night.
