City dwellers know finding green space can be a challenge, which is why so many urbanites turn to cultivating rooftop gardens. These smart modular greenhouses from Cityblooms sit at the cross-section between urban microfarming and commercial agriculture.
As the world's population grows -- it's expected to reach 9 billion by 2050 -- food security is increasingly becoming a concern. This kind of lightweight gardening solution could help alleviate issues.
The tiny farms only weigh about 16 pounds for every square foot. This means city folk can install rooftop gardens without having to worry about potential roofing support problems. You can combine any of the hydroponic microfarm units and track their growth too. This gives gardeners more control over aspects like irrigation, humidity and plant nutrition, especially compared to community gardens.
