I'm currently in the early stages of a 16g and I'm wondering whether I need a vent on the top, or can I just do a hinged glass lid? I will be manually misting so probably be opening it twice a day. Will this be enough air flow?

Glass lid would be fine. If you are worried about circulation you can always install a case fan.

I only have 6 vivs, but they are all glass lids, no screen.

I just finished up a 16g bowfront. There is a glass place near my house and I had them cut a glass lid with two 1 1/2 vent holes. I covered them fine mesh and secured in place with silicone.
The glass still fogs up so much I still have to wipe down so I can see inside....I'm considering adding a fan to one of the openings.

Make sure you're using in tank cirulation, not pulling the air (dry air) from outside the vivarium into the tank.

i like glass with a cut whole for vent and a fan for circulation.. keeps humidity up.
