Canna D-Block 1L

Canna D-Block CANNA D-Block is a product that is preventative against blockages when used in addition to your main nutrient products (in the same tank). It makes sure your pipe work stays clean and blocked pipes belong to the past so that your plants get the feed they need. If you are growing organically only use CANNA D-Block as a flush to clean your pipes and drippers between crops.
