Yo, @wekesa zab ! We're actually pretty intentional about keeping surplus low to limit waste. Once the family is familiar with the unit, and has a sense of their base consumption needs, they could then chose to produce more for their neighbors or communities.
Love the idea of bringing food closure to consumer. You mention you're interested in getting the perspective of farmers, what things specifically are you lookings to learn (interact with a lot of farmers during my day job)?
