Self watering or sub-irrigated planters introduce water from the bottom of the planter allowing it to soak upwards through the soil in the columns to the root system. This allows the plant(s) to take on water as needed and allowing for optimal plant growth. The water contained in the reservoir is protected from wind and sun, significantly reducing evaporation, and dramatically increasing water efficiencies.
These self-watering planters feature an innovative double hull that creates a reservoir at the bottom of each container.
A tube protrudes above the soil which allows the reservoir to be filled and a drainage hole allows for extra water to exit the reservoir.
