- full_unconnected_stem: itemstring of the full-grown but unconnceted stem node. This node must already be done
- connected_stem_basename: prefix of the itemstrings used for the 4 connected stem nodes to create
- stemdrop: Drop probability table for all stem
- gourd_itemstring: Desired itemstring of the full gourd node
- gourd_def: (almost) full definition of the gourd node. This function will add after_dig_node to the definition for unconnecting any connected stems
- grow_interval: Will attempt to grow a gourd periodically at this interval in seconds
- grow_chance: Chance of 1/grow_chance to grow a gourd next to the full unconnected stem after grow_interval has passed. Must be a natural number
