Default Vent, Fan, or Vent & Fan?

I have an 18" exo cube. That is sealed up except for the exo vent on front and the tiny gaps in the door. I spray once a day and humidity stays around 80%ish. BUT, the 3 windows are always condensed up.

So I have been reading about how to solve this, but I'm confused if I just make a vent and recut the glass on top - will that will be enough to alleviate this or will I need a vent and a fan to really get rid of the condensation.

Any help would be greatly appreciated!

i was told vent for sure, because the plants release CO2 at night that will toxify your frogs.
the fan is for air circulation, beneficial to some plants, it also helps with sreading the fog if you plan to get a fogger.

so I reccomend both.

you could also just try the fan, if it's not enough then cut a vent.

I leave one of the front vents open. Mist once a day and my humidity stays aat 95-100. If there is moisture on the glass for a long period of time and it is not evaporating, that means there is nowhere for it to go. Ie. Ur humidity is higher than you think. What type of gauge are you using?

Plants actually use the CO2 for cellular respiration and convert it to O2. If you use a fan, make sure it isn't going to create a whirlwind in the vivarium by being too powerful. The fan will lower your humidity so you will have to mist more often, however it will create air flow which some plants such as orchids require; it will also clear up the condensation on the glass.

The vent at the front bottom of the tank allows the CO2 buildup from detritus and the frogs cellular respiration to exit the viv. CO2 is heavier than O2 so it stays on the bottom of the vivarium. With the lower vent and plants, plus opening the door to feed the frogs, you don't need to really worry about CO2.

I'm of the opinion that vents are more important than internal circulation fans. I have passive vents in every one of my vivs (with the exception of a few froglet raising tanks). Additionally, some of my vivs have internal circulation fans. I love both, but if I had to choose one or the other, it would be passive vents.
You can always try a passive vent, and put a fan in later if required/desired.

Thanks for the thoughts guys. I know the frogs are fine - I'm not worried about CO2 buildup because of the low vents in front. I am simply annoyed by the water that is constantly collecting on the front and sides.

That is a good thought about my humidity gages. I am using one of the cheap exo terra dials. I will up grade this and see what it says my humidity is it.

I think I am going to at least put a vent in the to - following your previous instructions doug. Then the fan I will save for further down the road if necessary.

Thanks everyone.

It all depends on local conditions by you. People living in Arizona need less venting due to low humidity in the external environment. People living in western Florida and louisana probably vent more due to higher humidity.

You could build the vent and if its too much, you could wrap it in Saran Wrap if you're leeching humidity. It's harder to add once frogs are in there since you have to keep lid on or cover with something else while your lid is completed.
