So we have a free hectare and we want to produce food. We decide to culture wheat in that space.<p>Our wheat would reach around 1m high, thus our "food 3D printer" has a volume of 100 x 100 x 1m. We could obtain 2 to 7 tons of wheat in that space<p>With corn our production space is 100 x 100 x 2 m and we can obtain on average 5 tons of corn (but we could obtain 7-10 tons with some extra effort).<p>With avocados our production volume is 100 x 100 x 25 m. We could obtain between 7 and 13 tons of Has avocados, but with a good culture practices, good rootstocks and smart planning we could produce 23 tons<p>With Oranges we could harvest also 10 - 22 tons of oranges<p>And bananas would yield 50-60 tons of food... on average<p>So If our goal is to feed as many people as possible, what should we culture, trees or herbs?
