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.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.
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
