Lightning in a Bottle: Plasma-Activated Water for Hydroponics

This episode explores plasma-activated water (PAW): how ionized gas (like lightning) can be used to create reactive oxygen and nitrogen species that supply plant-available nitrogen and act as a natural sanitizer for hydroponic systems.

We cover potential benefits (reduced synthetic nitrogen use, biofilm and pythium suppression, no toxic residue), practical approaches, current research and real-world trials, plus limitations such as dosing control, decay of reactive species, equipment costs and energy demands.
