Temperature control advice/help

Hi guys, Getting ready to setup my first ever grow but having a huge temperature problem. My equipment:

80cm x 80cm x 180cm Tent

600w MarsHydro LED (275 true watt)

105m3/h (61cfm) Exhaust fan with carbon filter

Passive intakes

Outside room temp is around 20-23C (68-74F)

My problem is temps are not getting below 32C (90F)

So I just ran a test:

Temp inside tent with nothing on - 23-25C (73-77F)

Light on with no extraction for 1 hour 30 mins, then measuring temps - 33-35C (91-95F)

Extraction on for 1 hour with light, then measuring temps again. - 33-34C (91-93F)

It seems my light is increasing my temp in my tent about 10C, is that normal?

It also seems my extractor fan is not really removing any heat from my room, maybe about 1-2C.

So heres my dilemma do I buy a smaller light, do I buy a bigger exhaust fan or both?!

So any advice/help would be super appreciated.

I'm 58cm x 58cm x 158cm and running a 4", 171 cfm exhaust fan w/ carbon filter. IMO, bigger fan. 600w sounds like a lot, though. I don't know what the heat-equivalent is compared to what size hps or cfl. I think the golden rule is you want to remove 3x the cab space a minute minimum? With a carbon filter and a bend in ducting, my 10x per minute is greatly reduced.

Thats the kind of fan i want to upgrade to, do you know how much it reduces your tent temperature by? Like with and without it on?

Dude seriously??
How many threads are you going to start asking the same questions.

You've gotten a bunch of advice already
