What do you grow on your farm?
My wife wants to grow lavender and distill it. That stuff is in demand apparently.
Corn, wheat, soy, and sunflowers. Food and oil.
Lavender isn’t a bad choice, its high profit margin BUT hard core aromatherapists (a hobby of mine) will only buy French, English, and Bulgarian because where it grows affects the constituents of the essential oil. However, she could probably sell it to a MLM like Young Living or Doterra. They grow their own but I have heard they also buy from outside sources.
