No, not terrariums. Start them in a pot, then you can move some to a terrarium, or do whatever you want. Here is a link that will answer all your questions.

Regards Devin! Happy growing. I hope they grow well for you!

They do very well at window sills and/or under artificial lighting.

thanks for all the tips. again, anything you can tell me would be nice.

petiolaris said it best, no terrarium needed. A bright Windowsill is best. CPs should not be grown in terrariums IMHO.

As soon as I have room in my terrarium that is where I'm starting my capensis seeds. IMHO I think they will get a better start with the added humidity. I wont leave them there though. Once they get a few leaves I will move a few of them to my grow area under T12s and some to my window sill. I hope they get large enough by summer to move some outside to the deck where they will get full sun in the late afternoon.

My cape sundew was ordered online and didn't have dew, I purchased a terruim and put the plant in it and a week later it was covered in dew! I strongly recommend a terruim.

The dew should come from having enough light (energy) to produce the dew. Is your terrarium also having enough light? That would be the main reason why the sundew has dew, not so much that it was in a terrarium.
