Free CO2, about double ambient, gasses out from roots during lights off.
Therefore, 2 grow rooms, well sealed, cross ventilated, one ON one OFF, symbionically support each other because both have what the other needs.
There's no extra carbon footprint and a biomass increase to your show, all that's required is hook two rooms together in a well constructed tight environment that preserves & uses outgassing CO2.
Additional savings heating & cooling via cross venting on/off rooms plus the CO2 recycle for more biomass.
