So I got a new vivarium for my 3 to 4 year old bearded dragon because his old one was getting tacky in terms that I had to replace the entire bottom.
So in this new viv, I can't seem to get the humidity down. It's a 2nd hand vivarium which was originally brought from swell reptile I believe the original owners said.
The humidity ranges from about 65 to 70% at night and drops to about 35 to 42 during the day.
I have pushed out all of the plastic ventilation things (I can't remember what they are called) that he won't be able to get out of and the window closest to his viv is opened 24/7.
His UVB is 3 weeks old and his temperatures are perfect.

Can anyone give me any sort of advice on dropping the humidity?

You could add more ventilation, use a smaller water bowl (or move it waaaay over to the cool end If it isn't already)
What substrate are you using ? Some will be holding more moisture than others although might dry out enough after being in there for a bit. I realise that not all , or possibly any of these may be the issue for you but if all else fails ventilation is probably the key. Hope this helps :)

It's Lucky Reptile Desert Bedding as it's the only substrate I can get where I live that is clay like. (I have tried tiles, wood chippings, Lino, etc, but he stopped eating and became extremely stressed, wouldn't use the dig box and started to damage his claws so I had to change to it)

I was thinking that but I don't know if anyone knows of a good extractor fan? I have never needed it in my old viv or my females...

It's the Komodo hygrometer

A PC cooling fan turned around will do the job :) slimline and silent however you would also need an appropriate power source (someone correct me if I'm wrong but a mains to 12v sounds about right). There might be packages on ebay for it?

The humidity sounds VERY similar to the humidity outside though, have you tried closing the window?

It's slightly higher with the window closed by a few % so I thought it was best to leave it open to drop it even by a few %

Interesting... Correct me if I'm wrong but the bedding is dry is it not?

No water bowl...

There are only 2 other things I can think of, you have a very humid room. Or part of that viv is retaining water/rotten.

Aside from that I'm baffled!

On a side note...Why are we all still awake? Lol

There is nothing wrong with that humidity as long as there is good air transfer. Take a look at the humidity in much of their home range and youll find it pretty much matches up with what you are describing. Its only of concern if you have a poorly vented/circulating enclosure where fungus can build up. If you really want to get it down more then cut out a hole above your basking area. Screen it, put a larger wattage light in and watch the humidity plummet. ;)

Hmm, are you sure? I have been told by the local reptile vet and my friend who is a reptile expert that it needs to be about 30 to 40% or they could get a respiratory infection... There is defiantly no sign of mould thankfully

The bedding is bone dry, I check often, Daisuke has a terrible habit of spreading his greens every where so I spend about 30 to 60 minutes a day/every other days looking for any food he's decided to bury.

I don't think my room is humid, I personally have no heater in my room (other than the viv) but I've found out my sisters been closing my bedroom door during the day when I've not been around so he doesn't escape into her room...

I can't sleep :( what about yourself?

Booked 2 weeks off work, slowly sends me nocturnal!
Then when I go back to work I just die for the 1st week lol

I'd still be checking the integrity of the viv, aside from that matey boy above has provided some words of wisdom

What are your temps and where are you measuring your humidity? With sufficient high temps I'd imagine your basking zone would be much lower in humidity.

In addition to all the other comments, there's a high chance your hygrometer is just naff. They are rarely accurate and require salt tests to make sure they're correctly calibrated.

Digital is better than analogue, but really can be hit and miss when it comes to hygrometers.

Tomcannon - it's about 35C under the basking spot and about 20 to 25C in the cool end
The hygrometers are at the back on the side walls and are digital

Jesterone - it could a really off set I got... I'll look at how to do a salt test and see if that helps

I'd run a hotter basking and cool temp. Your beardy will probably prefer higher temps as is standard and it'll reduce humidity. Also if you read your humidity level under the basking spot it would probably be much much lower. The key in my opinion to humidity is not to eradicate it but to provide it in a decent gradient alongside your temperature gradient. So with a very hot low humidity basking area with cooler areas which provide higher humidity levels.

Ya, I agree with Tom. Boost your basking area to around 40-45 C and the cool end to around 27 C and you should see your humidity drop and your dragon probably get a little more energetic too.

Cool, I will get a higher wattage bulb tomorrow.
He is a very active beardie, always running around trying to be Mr Escape artist or wanting a cuddle until he decides enough enough and basks the day away

I have three digital thermometers and if I put all three probes next to each other and leave them for an hour our two when I come back there can be over 20% difference on the readings of all three. I think Jersterone's right, they rarely give accurate readings so I wouldn't worry too much about what the hygrometer is saying.
