StopBloc helps prevent irrigation blockages by resisting the formation of nutrient deposits in feed-lines, sprayers, drippers, pumps and filters.
- StopBloc also helps prevent build-up of nutrient deposits at the root zone
- Compatible with all types of nutrients / fertilizers, systems and substrates
- Use during vegetative & flowering
- For use in hydroponics, soil or coco
- Dose rate 0.2ml/L (0.8ml/Gal)
- Available in 250ml, 1L, 5L and 20L
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.
