Farm Plot 4 by 4 is a planter that can hold 16 plants.
Completing "Plot Holes" will reward the player with 1x Farm Plot 4 by 4 and the blueprint to craft more at the Workbench.
Farm Plots are used the same way as regular planters. They can be placed and removed with the Hammer, or moved with the Item Shifter.
Once plants begin growing in a Farm Plot, moving the actual item will not affect the position of the plant.
