2x 600 hps 2.4x1.2x2.0 tent severe heat issues

Hi guys in real need of help with my set up this is the hot weather just kicked in up in scotland and i am struggling to get my temperature below 40c or 104 degreess f
my tent is a 2.4L X 1.2 W X 2.0H meters high running 2x 600w hps lights and a 6" inlne fan and 600mm carbon filter fan which should be effective enough to pull the heat out of my tent there is also a pedastel fan circulating the air in the tent. i have also got the air from the tent blowing out the room via an open window but sound is an issue as i am not wanting detected for obviouse reasons i have recently just add another fan pulling fresh air from outside into the tent to try drop the temperature but nothing seams to be working has any body got any ideas please help as i am having to feed my girls every day to keep them from severe drying out in this tropical climate the humidity is only 26% also. cheers

Air conditioner in the tent maybe? They sell stand-alone AC units that are awesome if thats in your budget. Other than that maybe just use one 600 for now until you flower if your still vegging. I live in hot ass weather myself I feel your pain.

Yup, AC will be the only way if you want to run both those 600W's.

Alternatively during the day use 1 600W and turn the other on later on during the cooler hours.

regards,

cheers guys have been thinking about an AC unit for a while now but thought maybe so more experienced growers maybe had a different solution but its looking unlikely. i really cant run just 1 light during the day not wanting monsters on 1 side and dwarf plants on the other lol

have also been thinking of getting an air cooled shade for 1 of the lights and duct it out the house to keep the temp down a bit wht use think???
