If I have unused discs from a 2020 purchase are they still going to be effective?
The Gentrol Point Source Stations when unused will have a shelf life of 5 years per the manufacturer Zoecon. Once activated, each station will continue to give out the growth-inhibiting vapor for 3 months (90 Days) before each station would need to be replaced.
