I think the method that thedutchie13 is using is best.
Nothing to mess up, no air stones, no pumps and great yeilds.
You are correct in that most people often do ventilation as an after thought, and it is so very important. Not just for achieving the correct temps, but to replenish the co2 that the plants have used up too.
You'll see alot of posts here asking about home made brews for co2, but they have crap for ventilation. A proper ventilation system will beat any home brew, all day long.
Peace
