There is only one scrubber in the workspace, because I smoke in there and its gonna smell with the flower room only recirculating and not exhausting. The second one you see is actually for my dryer.
The veg room is cooled by the scrubber, and having mother plants in there its gonna smell a bit. I run an almost identical veg room now, and temp and humidity are perfect with the scrubber running 24/7.
Also I think my 10000btu AC will do the job. It was keeping 2000w cool in my 5x5 tent, I only turned them down to avoid bleaching. This area will be a bit bigger than that. Also forgot to add co2 and circ. fans to the drawing.
