The plants in the first pix are 4 week old cuttings that have been 'enhanced' for the last 2 weeks with a CO2 generator. Incredible growth rate.
The second pix is my laptop showing a CO2 monitoring program called ZG Viewer which is available with the monitor through CO2Meter.Com. I was able to use the monitor to fine tune the CO2 output to a very consistent level of 1200PPM.
