While the amount of light a VFT receives can affect the coloring of the plant and trap, it isn't necessarily the definitive factor. Some VFTs won't get real pink or red no matter how much sun they get. That depends on the genetics of the plant. However an east window should be ok for your plants. An eastern exposure isn't real strong sunlight and the amount of hours is limited (err...unless you live somewhere exotic... I don't know where you live.). In fact your plants might do better with a little more sunlight than that.
What you need to be concerned about with a terrarium and direct sun, is that the temperature doesn't build up inside and get too hot. Also you need good air circulation so the inside doesn't stay too warm and wet which encourages mold and fungus.
As long as you watch the temps and air circulation, I don't see any reason why your terrarium can't go in your window.
I think full sun would be fine as long as you watch the temperature. IF your terrarium is enclosed, the heat can build up very fast. Is there a reason you have the VFT in a terrarium? If you just like the way it looks, that's fine but you don't HAVE to grow a flytrap in a terrarium. They don't have high humidity requirements like some other CPs do. They can grow fine just sitting on a window sill or table in the sun. That also makes it easier for them to catch bugs. I have a VFT at work on a window sill and it does well.
Yeah...I finally changed my avatar. Thats my sweet dog Jonah. He is a hoot.
A general rule is all flytraps will go all red in the traps if given sufficient light, exept for the all green or yellow type.Some may require massive massive amount of sunlight to go red in the traps. Some will go red easily, like my dingley giant in jhaluska's avater.

Yes grow lights would be good for your plants....but I would use florescent lights instead (much cheaper). That is what I have been using for the past two years for my cps. I have a timer that turns the lights on at 6 am and turns the lights off at 10:30pm. Even when I go on vacation the timer still works durning that time frame.
That I can not ansewer because I have not tried grow lights. I am sure grow lights are better but is it worth paying more for a cp that may have the same results (whether grown by florescent lights or grow lights). I think grow lights are about 15 to 45 dollars depending on size compared to florescents light witch are roughly 5 to 25 dollars (this is a guess I have gone out personnally to check prices
) I also know that grow lights cost more on your bills...
