New Grow room problem Please help.......

My new Grow room is 3f bye 4.5f bye 8f it works out 80cbf i have a 600w HPS the ballest is outside of the room in the attic..I have a Vortice ca 100 which on full power should extract 250cbf with a Rhino carbon filter attached then i also have a 125 inline fan sucking air into the room....My problem is its reaching 30.5 in the shade so could i have to much ducting?????????Ive got my ducting running threw the roof into the fan units and pumping in and 1 out please HELP ME LOL....

got any pics?
is your intake at the bottom and your outtake in the top?
where is your intake taking air from?
i don't know how to convert 30.5c to farenhieght off the top of my head but im guessing that around 85 degrees.

I have vents in the roof of my house which which the air is pumped in and out the ducting runs to the vents and threw the roof of my grow room its doing my head in lol

beter to take air from a lower source for intake.. and did i read that right you have a 100 cfm for exhaust and a 125 for intake? you backwards if thats right.. your intake should be smaller than your exhaust.. plants like negative presure..

...check it out >>>

My exhaust even being a 100mm its more powerfull than the 125mm intake i know how it sounds but ive checked it out so its true i put both fans in my tent and it sucked the sides in nice its just not doing same now lol.....
