Will (4) SF-4000 create enough heat? Co2 in veg?

Hello all.... I have a dedicated veg space in the basement. It's a 18'x18' room and stays at an ambient temp of around 60-64 degrees all year long.
I want to run 3 or 4 SF-4000 lights over a 5'x16' table. Do you think these lights will get me into the mid to high 70's on their own or will I need to run a heater in this space? If I don't have to vent the room to maintain temps is it worth while to seal up the room and supplement co2?
