Innovations of the gardening kind are popping up for the city set who want to grow their own food in the smallest of spaces. One of the new kids on the block is Edn, a plug ‘n play vertical garden system. Edn is a vertical garden system that packs a hard punch—making it possible to grow up to 21 vegetables at a time inside the comfort of your own home. Edn comes with an app, which acts as your personal gardening assistant and teacher. In your app you record which plants you’ve chosen, and it will do much more than tell you when to refill your water tank, though it will do that as well. Read more about this system in the source.
