the dimensions of my growroom are 4m x 3m and 2.6 high.in it theres a flowering room thats 2.4m x 1.2 x 2.6m high with a 600w hps and a 430w hps that im thinking of replacing for another 600w and a small veg space with a 430w for the mothers ,a dresser with 8 cfls ,i got a fan on a cooltube on every reflector but still its getting a little hot 26c to 27c but thats not s problem now what im thinking whats gonna happen when it gets hot outside for now its cold 0c maybe 5c,so i wanted to get a aircondotioner,my question is if i set a airconditioner how much do i need to ventilate fresh air from the outside couse if i keep the air flowing from outdoors at this rate the AC could never cool it
