CO2 monitors โ Episode 2: In which I learn their highest... and best use
Three weeks ago I featured a high-priced ($461) indoor CO2 monitor and noted that I couldn't see why anyone would want one.
A reader commented, "Dope grow room!"
Doh.
Shows how little I know about the world.
I need to take a cue from Gray Cat and get out more.
But I digress.
Two other readers offered sites selling a much less expensive CO2 monitor [top].
In the interest of discretion I'll pass on acknowledging these tuned in... individuals by name.
Heh.
Best price: $189.95.
