Fancy hydroponic setups aren’t almost 0 cost. Vertical farming is not cost competitive with the farming that we have.
There are companies like http://rowbot.com/ who develop farm robots to more effectively use fertiliser.
There are plenty of devices for growing food at home on kickstarter.

Having fruit trees isn’t free. Having fruit trees in cities costs the cities enough to prefer other kind of trees.
It’s worthy to be suspicious of free. Most of the time there’s some work involved. It’s worth understanding the hidden costs.
