Make the air come from the outside through a 4'' fan, run some ducting from the fan through your lamps coolable hood (assuming you have one). then shoot the air right back out the window. the only heat that comes off the lamp then will be able to be wisked away by an ocilating fan in your room. check out my grow and look how i got it rigged up. I don't have the input from the outside but its the same general assembly.

if your fan is on a thermostat (not running all of the time, only when temps get too high), bring the air in and run ducting to the highest point in the grow. The cooler air will drop to the floor and mix with the hottest air in the room. What I would do for this, is reverse the job of the intake with the exhaust for the winter and switch it back for the summer months.
So... Draw the hot air from your grow at a low point, and bring your cold air in at a high point.

THIS ONLY WORKS FOR TEMPS THAT ARE FREEZING OR LOWER.
If you need a pic I will draw it up for you.

thanks, u don't need to draw me a pic i got it is a good idea Thanks. but how i can deal the winter when the climate is variating so i don't have all the time freezing or bellow they can go also to
50°F.

Is this system can work with temp like this ? do you think is a good ideea to remove the cool tube to can provide more fresh air ?

No need for intake fans. Use an exhaust fan only. But yes, use a thermostat for the fan.

and how i provide fresh air in the box ?

through whats called a passive intake. Just a vent in the wall at a low point and your exhaust fan at the top will pull air out of the room, meanwhile fresh air enters the intake.
