GreenAir2 - The concept comes from the metamorphosis of butterfly (shown above). GreenAir planter (green part) is made of biodegradable material, so when the plant has grown up, it can be directly transfer to soil to let it grow bigger.
It has a fan inside it to pull the air to the root area, using solar panel as the energy source.
It employs self watering system, using nylon thread as the extension of the root. So, the plants can absorb water according to their needs.
