The other is to add much needed nutrients that deficient people need. Here is an anecdote from our adventure. We were able to artifically add enough Vitamin B12 to Spinach that non-vegetarians can benefit from. Vitamin B12 is not available in vegetarian diet.
The other audacious goal we tried. What if that same Spinash is loaded with enough nutrients for pregnant women that the malnourished women in rural India can get their fair share of nutrients during their terms for a healthy mother and a healthy baby!
These specialized way of farming can only be managed by a well managed indoor farm. For instance, in a country like India with enough sunlight, besides leveraging solar energy, we can also make the plants have enough sunlight while still inside the farms. So, combine a mix of hydro + the likes of Dutch Bucket Method can make way for lot cheaper way of indoor farming.

Edit: Sorry for feeding the wrong nutrient. Vitamin B12 and not K12.
