Fertigation system is vital to ensure a consistent growth and coloration of plants at vertical garden wall while it curbs wastage from material, manpower, equipment. It adds water-soluble micro and macro nutrients to irrigation water.  The automated fertigation system is designed with multiple pressure compensated  drippers inserted into the planting medium to deliver water and fertilizers directly to the plant roots. The dosage will depend on growing media where more frequent fertilizer application is needed for soilless mixes with lower nutrient holding capacity.
