The Beneath may be a harsh environment, but it is still possible to find crops there. Beneath crops are incredibly resilient and can grow in extreme heat conditions making them useful for surviving below the Earth and on the surface.
Crops in the beneath behave just the same as crops on the surface, they have hydration, temperature, and nutrient requirements. You can even plant them in Greenhouses.
An important concern when planting crops in the Beneath is that crops require a light level of 12, which isnt provided by the Beneath's natural light. To solve this problem, you can utilize Lava Aqueducts or any other available light source.
