I'm running some tests and I'm having issues trying to get my viv up to the right heat level. From what I've read a 15w heat cord should be enough to warm my enclosure, however, I'm running a Reptile 1 2m 15w heat cord plus a 50w IR Bulb, and I can't get it beyond 26°c. (Aiming for 32°c as this will be for a Woma python). The cage I have is on loan from a friend as I'm getting a juvi. I plan on buying a 120x60x60 in prep for when it grows (as I hear they grow quick!) so this is the intermediate solution. Here's a pic of the cage (which is 60wx40wx50h). I haven't put in substrate yet - just trying to run tests to get an idea of heat and humidity correct first. Please excuse the layout. I haven't tied down the cabling yet - it's just hanging down. (One being the thermostat, and the other the heat chord) - at present, it's just about finding the right equipment for the job, and I'll worry about tidying it up next. Tech info: Reptile one 50w IR Bulb (on left side) Reptile one 15w 2m Heat Cord Microclimate Ministat 300 (which never reaches cut off temp, so it's currently been on 24x7). Ambient room temp between 13°-18° celcius. Lower vent on the cooler side (right which can be seen in photo) Higher vent on the hot side (which I have placed tape over on the outside in an attempt to reduce heat loss) Full solid wood roof, back, sides and floor. Only the front is glass.
