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

regards,

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
