Venting a SMALL stealth grow

my enclosed, insulated space is 40" wide 24" deep and I have about 60 inches tall max.
(36 cft.)

360 total watt actual CFL lights. 3x85 watt cfl, 4x26watt cfl all at 6500k during veg,
switching out to 3000k for flowering.

2 plants lighted from above, and in between the plants,

This is in a unheated basement which is 49F in winter and 57F summer. my air in will be from the basement and my exhaust, up a chimney.

I'm figuring on using a Titan Controls Apollo 2 timer to turn on and off the duct fan pulling grow area air from a 4" can filter. 15 seconds on every 30 mins, during light. The fan will pull about 125 cf/min.
does this air exchange sound like it's enough/often?

I have a temp controlled heater to warm it back up, if needed.

I would just run the fan constantly.

It wont be too much and it will keep the air circulated regularly.
 
49F air in will be way to cold for the ladies. I'm aiming at keeping ave temp as close to 75 as possible for a along as possible.
That is my question: is 15 seconds @125 cfm enough for a 36cft room?
