New Grow Room!

hi peeps..

i started building this room about a week ago and i will post all the info on it later as well as the pics but i have a problem right now... i am using a 600w HPS with a cool tube and an inline fan to pump the hot air from the light away... i am also running an portable A/c in the room to keep the temp down. i have a vent in the bottom corner of the box so that there is constantly new air going inside the box... my problem is that the inline fan just sucks the cool air from the A/c out and brings hot air in through the vent in the bottom corner, so my room is staying at about 85-90F midday.. should i cut another hole in the roof and have the inline fan suck air from outside? if so, will i have enough air/co2 circulating in the room?

below are some pics... sry about the quality... they are pics from my phone

Nice set up man.How many sq. ft. ?

If you can cut a hole up there...try it. By blowing through/pushing the air over the lamp & through the tube and out you won't pick up any smell from the garden. Then the AC can cool the space....

hopefully....

bt dt

it is 168 cubic inches. dimensions are 7'long, 4' wide, 6' tall. i am in the process of getting this room set up. its my first grow. i have a mother Purple Urkle right now on compact fluro's which i have been working with for around 7 months. this grow will be interesting, i am trying to get my hands on a clone of another Urkle plant so i can have it ready in a few months. i am trying to make this a perpetual harvest with a dozen new clones going in and another dozen coming out every fortnight...
