I need to know if the box of gentrol I purchase has already outlived it's shelf life. They seem to have nothing in the breakable tube.
The Gentrol Point Source Stations when unused will have a shelf of at least a year or so. Once activated, each station will continue to give out the growth inhibiting vapor for 3 months before each station would need to be replaced.
