Should the GreenGrid® system be irrigated?
Irrigation requirements will be dependent upon project location and plant selection. For Extensive GreenGrid® Systems planted with a mix of highly drought resistant ground covers, an irrigation system is generally not needed (exceptions do apply to some arid climates). However, we strongly recommend a backup system be available to irrigate the green roof during prolonged droughts or during hot dry windy weather patterns. Intensive GreenGrid Systems in most cases will require perminant regular irrigation.
