Unfortunately I’m kinda stuck with this set up until I have a bit more money, the reptile shop kinda did me dirty by convincing me this is what I needed. I only put it the 100 watt bulb today as the 60 watt bulb I had before wasn’t hot enough with the extractor fan on ( only getting to around 24 degrees in the basking spot), hence why I put a new stronger bulb which allows the basking spot to get to the proper temps required, plus if it is too hot then the thermostat should regulate that, right? As for the UVB, the website you just linked me to says that 12% is okay at a distance of 12” which it definitely is. I keep humidity around 40% in the day, air flow is kept up by having a fan attached to the back and creating a chimney affect ( which other members on this site have said works well for their wooden vivs). The fan is switched off at night along with everything else allowing temp to drop to around 17 degrees and humidity to rise upwards of 80%. Surely this is all okay? Plus like I said before, it’s only temporary while he is still small, I plan on getting a mesh hybrid once he is bigger and I can afford it
