Urban Leaf introduces the World’s Smallest Garden which enables you to convert any empty bottle into a practical planter. A round tool in the form of a test tube, it has a soil-like substrate with a seed that’s pre-planted, which means you don’t have to mess with particular dirt or trouble sourcing your seeds. After that, you just put it into the mouth of a container that has water.
Since the Urban Leaf World’s Smallest Garden is partially submerged, it uses capillary motion to drive water to the seed. Once the seed grows, it will send roots expanding right into the bottle, enabling the plant to draw water all by itself. They suggest putting the containers in a spot where the plants get a good amount of sunlight, like windows or decks. That way, all the upkeep you’ll have to do is watch the water supply and refilling it as needed (when the crops mature, they project you will need to add water 1x each week). As of now, they have 12 plants on the market, which involves kale, basil, lettuce, mint, and bok choi, with some more presently in testing, so the list should increase in no time.
