/**
 * This method will search through a vertical column of positions, starting from the top.
 * It will stop searching any lower once it hits anything other than air or plants.
 * Any plant found has an independant chance for a growth tick. That percentage is controlled by AgriCraftConfig.
 * Farmland also ends the search, but it first has its moisture set to max (7) if it isn't already.
 * The lowest position is special: a plant this far away is not helped. Only farmland is currently.
