These giant aerogardens can ease the strain on our planetary land and water resources, while helping to feed everyone!
It seems like a win=win, with these leafy crops growing and ready for harvesting in half the time of plants that come from soil.
Could be a good way to re-use empty buildings too..
And on a much smaller scale, maybe you already have one of these or know someone who does, you can have your very own little aerogarden!
