I took ownership of 3 new corns on Sunday (pics to come when they have settled in). They came complete with a viv stack and everything.
However, the stack is heated using bulbs which I don't really have any experience with so could do with some help. I bought some guards for it as there weren't any fitted and have installed some new digital thermometers today. It does have one already in the top viv but dial ones in all the others. All the lights are controlled by the same dimmer stat, the probe is in the top viv in the middle at substrate level. I have got it set so that the digital thermometer is reading from substrate level underneath the bulb.
The problems I am having is that the top viv is getting hotter than the bottom viv. Also when I wake up in the morning the thermometer in the top viv was reading around 31oC so I turned the thermostat down gradually until i was getting a consistant 28oC or so. But then I go to check on them around this time and the temperatures have dropped to 26oC. After installing the new digital thermometers the bottom viv was 3oC lower than the top.
The sun isn't on the vivs to make the thermostat cut the heat off so I don't know why it is being so inconsistant. Obviously I can't keep adjusting the thermostat and I want to get it sorted before it's time for their first feed with me. |

i agree with gp here, i had my corn viv ontop of my JCP viv. he had a 150w i/r bulb giving a basking spot 6 inch away or 30oC. my corn viv was seeing a temp of 33oC on the substrate an that was through 30mm of wood an the mat stat turned off. so had to make a stand to lift it up abit |

I much prefer using bulbs, but agree that in stacks they are a right pain. |

I have a stack of 2 vivs thinking one stat would be ok lol
Well let just say I got 2 dimmers now
The top light sometimes hardly on as the bottom one is heating the bottom of my season viv
I'd like to be the snake in the top viv best of both worlds |

When I got my Royal I wanted Spot to be in the top viv but I totally forgot about the heat rising issue and I found Spot hanging out in his branches and his temps were through the roof, shifted it the other way round and problem solved. I'm planning the viv stack for when my babies are all grown up and looking for some nice posh metal legs to create a nice airgap/shelf between vivs. |

the heat transfer can be an absolute swine..........i'd go for mats any day!!
if you get 3 the same you should be able to run them all through 1 stat and get reasonable temps hun  |

Mats will be loads easier to sort and they can be on the same stat so loads cheaper. |

Thats what I meant G. Using mats on mats stats instead of using bulbs. Just means that I have got to take the snakes out so I can drill a hole for the cables. N get the temperatures right |

mat sharing for lights is not recommended, Would either change to mats that you can easily share stats or get individual dimmers. |

Doh!!! Didn't think about heat rising. Yeah the roof of one is the floor of the next.
What do you think about the fluctuations in temp at different times of the day? I don't really want to be worrying about temps dropping to 22-23oC in the bottom viv when I feed them.
I think I'm going to have to disturb them and put mats in. At least I know what I'm doing with them.

In my opinion to get the perfect temperature setup the bulbs really need individual dimmer stats. As heat has a habit of rising the top viv will be hotter than the bottom one. An airgap or insulation between each viv will solve it but if your is a custom build the roof of one viv is probably the floor of the next one.
The best you can do for the moment is put the stat probe in the top one, don't want to cook the penthouse occupant.
