Setpoints — ShotCaller

ShotCaller LED enriched CO₂ working ranges: two vegetative weeks and nine flowering weeks. Temperatures in degrees Fahrenheit. Pair lower RH with lower temperature and higher RH with higher temperature. Temperatures and RH are rounded for display; VPD uses the unrounded temperature and RH pairs. Day air remains a nominal leaf +3°F starting point. Verify measured leaf VPD when setting room controls.
