If you were planning to grow plants at home, you really should take a second look at Urb Garden by Xavier Calluaud. It is an amazing vertical food garden that lets you grow plants and indulge in gardening even if there is no space for you to indulge in gardening in a conventional way.
It encourages the urban dwellers to grow their own food, however tiny their flat might be. The Urb Garden makes use of organic recycling and plant fertilization and can be used in balconies, courtyards or even in gardens themselves for their aesthetic appeal. It comes with a self-contained drip watering system which keep the pants hydrated.
It also allows for recycling and fertilization and you can grow your food at easy. You could perhaps grow vegetables, herbs like coriander, thyme, parsley and even lettuce. When you do so, you would not only save money but also grow food in an organic way which is clean, green and environmentally friendly. There is no information about its price or availability but I am sure it would be really popular once it reaches the market.
