The feed circuit, especially restrictive feed outlets like drippers, can become blocked with salt build-up, dirt, algae, root growth and medium.
To minimize this problem:
Employ a filter on the inlet to the nutrient pump. Also, in recirculating systems, install a filter in the return line. Ensure filters have a large surface area. This will minimize how frequently they need to be cleaned.
Position plants to avoid roots being drawn into drain outlets.
Maintain nutrient pH well below 6.5 to help prevent salt precipitation (particularly calcium sulfate).
Routinely disinfect the nutrient solution to prevent the build-up of algae and slimes.
Ensure nutrients are fully soluble.
Avoid using water that has high “hardness” levels.
Use a regular maintenance schedule. Routine 'discarding' and 'flushing' will help prevent the build-up of solids such as insoluble salts, algae and plant debris. Between crops it is useful to perform a chemical flush to remove insoluble precipitates.
