CANNA D-Block is an organic product based on anionic detergents. It cleans and prevents blockages in drip and sprinkler systems during cultivation. It also prevents the build-up of precipitants.
Use CANNA D-Block preventively with each irrigation (the product is completely non-toxic) and make sure that the pipes and the dripper remain internally wet between irrigations.
For each new cultivation, it is recommended to fill the system with clean water and D-Block (with an adjusted pH of 5.2) to protect the system and prevent blockages during the next cultivation.
