bird 1. farming in caves
WHY?
- should be possible for some crops
- it's been talked about by devs a few times
- potted plants can grow underground
bird 2. some form of over-winter farming should be viable
WHY?
- some crops shouldn't die in winter
- raised beds prolong planting season IRL
- potted plants can grow in winter
Generally, the concept would be that we make dynamically sized structures that we can plant crops in, the structure itself (and/or the fuel you add in it) can even aim to softcap the product to balance the overall benefit it would give to the player.

The idea is that we would be able to click-and-drag the build much like a fence, it would be a 2xX structure so both sides would be reachable for harvest.
Likely built with boards, glue, blocks and a buttload of dirt. After that you should need to keep the bed watered and filled with compost. If either run out, a timer starts and if it reaches the end the plants go fallow.
I think even the average hermit could aim to benefit from something like this by first winter, and it would definitely be a way to extend the larp underground and keep some cave crops running over winter at lower qualities for animal food or something even for bigger villages. The structure and/or fuel softcapping the crop would likely put them behind the quality of other plants over time, but perhaps this would be a fair cost for being able to grow in winter/caves. This could potentially also lead to specialized cave cultivars (think endives) in the future.
