Get a 250W, I dont think increasing exhaust size will lower the room temps enough.

buy an air cooled hood----->Bash some holes in your wall---->run some exhaust-----> connect a/c vent to cupboard via ducting.....problem solved.
Dont downgrade to a 250w, buy a cool tube and possibly a 6" fan with at least 300cfm and your good to go
thx kush cool tube sounds good. when u say 6" fan do you mean table fan or fan and filter
i no i am thick or do u mean buy another 6" extract fan
You should get a cool tube w/6" flanges and a 240cfm can fan, it's only 85.00 foa a 5000btu A.C...never be concerned with the weather! set it and forget it keep's temp's and keep's Co2 in space!!...work's good for me!First pic 3 rd week flowering...simple grow set up cost me 237.00 to build! found A.C. for free craig's list!too heavy for retired woman to move so I gave her 50.00 and she was more than happy! high heat = fire if your not careful think out your grow....inside there would go with flouresent's..??2 week clones purple haze.jpg!6 inch cool-thru 32 inch sq reflector.jpg1000watt HPS cool thru xxl hood 34000btu output!.jpgclone and flower room's.jpg429 cfm exhaust thru lamp outside.jpg500btu A.C. 77 degree's allway's!!.jpg

Yeah dont downgrade your light power if you can avoid it. Like these guys say if you can spring for it, get an air cooled hood for your light and increase the diameter of your exhaust fan. I also use a 4 inch fan bringing in fresh air from outside into my tent and that helps some and it also helps to bring fresh air in.
See, after running a 400 for awhile you probably wouldnt be happy with a 250. An AC unit is another option but I try to avoid that since I'm already running 2 400 watt lights and enough fans to lift off the ground with and my electric meter is already spinning right off the house.
Good luck to you
