The Mona Link 7 is a versatile and highly efficient subsurface irrigation system designed to deliver water directly to the root zone of trees, shrubs, and plants. Each Link 7 tank holds 7 litres of water and can be connected in sequence with others via flexible tubing, making it ideal for large planters, green roofs, roundabouts, interior planting beds, or unusual shapes like staircases or sloped areas.
The Link 7 is part of the Mona Plant System, a 100% water-efficient solution that stores water underground and releases it slowly to plant roots as needed. Designed for both interior and exterior landscaping, the system is unobtrusive, easy to install, and customisable to fit even the most complex planting designs.
