I have tested this. I own a data logging CO2 monitor and yes if you have good air turnover the CO2 was generally well over 500 ppm at all times.
Good to hear results from someone other than evil corp lol...Have you measured Co2 levels outdoors and if so are they really around 400ppm? Like nfhiggs I am naturally skeptical especially when it comes to anything mainstream puts out.

And tell Robin apologies that I lost touch, I haven't forgotten him, just had a lot happened this year, decided to do a few jobs to build up some funds currently on the last one then I will be in touch for a load of your Quantum Boards hopefully by the end of August;)
