1000HPS Small Room Venting Questions.

Will a 1000w HPS in a 6" air cooled reflector get too hot in a room that is 4x5.5x6 if I pull air from inside the room as opposed to pulling cooler air from outside the room.
I am wondering because I would like to limit the number of holes I am cutting in my house :).
I have a flower and veg room. I would like to use the air off of the 1000w HPS to heat the veg room, but am concerned that temps may get too hot in the small flower room if the reflector isn't completely sealed.
I live in the North Bay, CA, so temps don't drop below freezing too often, but I do live in an old house with no heating and the veg room has a wall that is exposed.
Check out the image, blue is cold air, red is hot air.
I know I need to test it myself, but before I go cutting holes opinions would be appreciated.

HEY HEY HEY HEY!!! i want to help you. I bought a 1000 watt hps and a 4x8x7 grow tent and just the venting of the cool tube into the room turned the whole room up to 90+ and was FUCKING my central air conditioner. The ONLY solution since I have a big window and cant create an air box was to cut a hole in the ceiling and vent through the attic. it sucks so hard since I rent and am gonna have to fix it but it was the only option. I HOPE YOU HAVE BETTER LUCK. just ask if you want pictures

So you pulled air off the 1000w and it raised your room temp to 90?

My ambient temp drops to 40 at night right now, 30 during winter, and day time it is around 75 now, drops to 60's in winter

Yes the air coming off the cool tube was being vented into the room outside the tent (which is a bedroom) and it rose the temp to 90+ which in turn raised the intake temperature for the tent (and also really screwed with the thermostat for my air conditioning)

I live in a warm humid climate so the cold in your area might be enough to keep in under control but having the outside temp at 88+ and the air conditioning fighting that plus all the 1000watt HPS nastiness in the actual house really didnt work for me. Thus the ceiling had to be cut :(

Im in Canada and its n my basement but it definitely gets a little cold in the winter!! How would i go about raising the emp at night when the lights are out???
 
It might be to hot, the faster the air is pulled the cooler it will be for your veg room, Check out my pics and I have 2 1ks HPS venting at the moments, and the air comming out is about 75 or less. What about sutting a hole in the floor under the carpet?
