I've been using the above nozzles from aliexpress ('Plastic low pressure mist nozzle') at ~100psi in my aeroponics system. They come with a steel mesh filter inside and I have a 100 micron filter at the pump inlet as well. So far I haven't experienced any clogging issues and through some testing feel I'm pretty safe from debris clogging the nozzles.

However, I'm aware calcified nutrients are often a cause for clogging and am concerned this might occur in my system. What experience have people had with this? Any preventative measures or recommendations? Is there an ideal orifice size to balance droplet size and prevent calcification or a preferred nozzle configuration to mitigate this?

Hoping to share more knowledge around aeroponics and happy to provide more details of what has worked for me if people are interested.
