My house has central AC and stays around 73 to 78 depending on season. I have a 12x12 bedroom with a 4x4 tent with 600W HPS. This bedroom also has 15k btu window AC to supplement my central ac. I want to passively intake from bedroom and exhaust into SAME bedroom. Ill add dehuey and CO2 if necessary. Main concern is temp. If sealed rooms maitain temp with 4k btu cooling per 1k light, is it feasible my 15k btu window ac will cool my tent exhaust fast enough? Kind of the same concept as sealed room of constantly heating a room up and battling it with AC except Ill be able to keep negative pressure on tent to scrub odor. Does any of this sound feasible?
