With the mean experiment-to-date airspace CO2 concentrations in biospheres 1 and 2 getting close to the 100 ppm mark, the death of parent leaves in these tanks continues.  Tank 2, at 117 ppm CO2, now has four dead leaves; while Tank 1, at 135 ppm CO2, has four and a half that have died.  In contrast, no parent leaves in Tanks 3-6 have yet expired, although a few appear to be losing chlorophyll and are starting to turn yellow.  Our standard measurement updates for new-vine length per plant and primary and secondary root length per plant are depicted in Figures 1, 2 and 3, respectively.
