Revolucionary: Forget to irrigate, plants take the water that they need at every moment.
Simplicity: You just need to do an earthmoving, not very depth and install the system. Forget electronic devices, complicated programs or instructions. When the system is already installed, it works automatically and without electricity.
Without maintenance: Only administrate a constant source of water. You can fill a water tank or connect to the mains water directly.
Lots of possibilities: The system can be placed anywhere with any climate. The same system works for an orchid, a garden, terraces, sloping surfaces...
