I recently put together a new rack system, mainly for geckos. It's 3 levels high with an 80watt heat cord from the herp shop connected to a pulse thermo. Each level has three grooves routed into it about 2 inches apart where the heat cord lies.
I am using starmaid containers however if I have them sitting so that their shorter side is running parallel with the cord I am struggling to make the desired temps, if I turn them around so their longer side is parallel, it's getting to a higher temp but is still taking a long time. Now where the rack is currently located it is quite cold and being in Melbourne that doesn't help.
I thought using three runs of an 80 watt heat cord I wouldn't have any trouble making the desired temps but not so. Other then moving the whole rack to a warmer room is their anything else I can do, or something I have missed? I have also put some foam insulation under the shelf to keep the heat in but it only had a minimal effect. The only other thing I can think of is adding more runs of the heat cord.
Any idea's?

Is it worth making a small square with some wood and placing a thin layer of sand in this directly above the heat cord and then place the tub over the thin layer of sand? As the tubs I am using are not perfectly flush and I think there might be some loss of efficiency there?

I'd also have a well insulated hide right above the heat cord. This well help retain a lot of the heat creating a nice spot for the gex to go into to warm up.

I would get some flat bottomed tubs and have a thin layer of sand above the heat cord (in the tub) but if you want to keep the tubs you have then yes, what you suggested may help a little.

|  | Let the haters hate. Subscriber | Join Date: Jul-06 Location: Sydney Gender: | | | | Just a thought JP2 but if you put enough sand in there for the gecko to burrow in (assuming there are nephrurus) then the insulation in the burrow should reach the desired temp?

What temp is the room dropping to at night.
Could you post a pic? PM or email it to me at junglerobb@hotmail.com
Should be easy to sort out. |

| | Willia6 fan Subscriber | Join Date: Jun-06 Location: Victoria Gender: | | | | Thanks Rob I will get some pics to you tomorrow, I am trialling 30L and 15L tubs I think, but I will have to double check. The room gets quite cold at night as its not insulated and being in Melbourne, but even during the day it takes a long time to heat up.
