CO2 monitors โ€” Episode 2: In which I learn their highest... and best use

2werfgh

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.
