a couple questions

[little_dragon_]

I live in Ontario, my room is in the basement I don't use any heat lamps. If you are worried about your crested gecko's getting too cold although I highly doubt it. Put their tanks by a vent. So they can get heat in the winter, and colder air in the summer. My fluorescent strip lights give off enough heat near the top of their tanks so if they need extra heat they can climb up on the leaves and get a basking spot of 80 degree's. In the winter this is about 74 degree's.

Anthony- Got your temp. gun ready? Looks like we is gonna have us a good ol fashioned temp gun dual!

I don't need to convince you that the room temp is different for you because I think that we can both agree that room temp is whatever you keep it at. Mine sits at about 68 during the day in my reptile room to accomadate my leaftails. It dips down lower at night. If the basking spot was 100-105 I'm sure that my Phelsuma would have been crispy critters ages ago, and unless my temp gun is broken the basking spot is sitting at 88 roughly 6 inches below the lamp. It is aimed at a 30 degree angle though, so I'm sure that probably plays some part in dipersal of heat.

I think the point I was trying to make is that with two 50 watt bulbs on the tank concept3 is seeing a temp variance of 8-10 degrees. That would make the cage temp vary from about 60-70 with no supplemental heat source. I definitely don't disagree with you on the heat requirements, and I only put 15 watt bulbs over my Rhac cages for basking purposes during the breeding season. Heat tape or a heat pad was something that I did overlook, and would be the preferable way to raise ambient temps in the cage overall. I was workin the light angle because it was what concept3 said he/she was working with. In my opinion 60-70 is going to be on the chilly side for proper developement of a juvie crested; therefore raising the ambient temp by any means wouldn't be a bad idea. I've never noticed juvies basking, only my gravid females, so I stopped offering a basking spot to juvies a few years ago. Whether or not the juvie fries itself under a 100-105 basking spot is probably irrelevant, as you pointed out it just won't use it.

I don't disagree with anything you've said. So please don't take this the wrong way.

Incidently, I'll trade outdoor temps with you any day!

ok i have several undertank heaters not being used right now, are uth a good way to raise ambient air temp? lol i know that sounds dumb but im fairly new with lizards i mainly deal with frogs that sit directly on the uth all day and the ambient isnt very important.

Basically, whatever heat you are using your daytime temp should be 70- 75 and your night time around 65. There temperatures in the wild are even known to drop as low as 50 degrees. Temperatures around 80 degrees over time can be harmful to cresteds. Also mine are kept on organic paper towell that is kept ever so slighty damp. (just a light mist on top and not even all the time) I don't think uth raise the ambient temp much if at all but I've never really tried it Hope that helps.
