Hello, world! First timer here.

I did a bit of researching through the care sheets and a few others posts. It looks like my question has been asked in some other threads (not as the main topic,) but with mixed answers. I'm looking for the final word on this one. Anyway, here 'goes...

I'm setting up a tub enclosure for my future ball python. I've used a tank setup in the past, but I want to be able to use a tub for its ability to retain humidity and to provide an environment that allows the snake to feel less vulnerable. Right now, the tub's ambient temperature is at 84* F. The basking side is set to 92* F on the thermostat and the basking thermometer reads 90* F on the nose! Not bad for a first run! But my concern is that this may not be easily-maintained in the future. In the summer, my room hits a high of about 78* F, but it can drop down considerably in the winter. I don't want to have a situation where I'll be panicking about the temperature, I want to be prepared for it!

I've seen a few people write that an additional heater isn't necessary, but I strongly disagree and this is where I need your help. The bottom line is that if the ambient temperature falls too low, then there's a problem. If the snake isn't comfortable, then neither am I. I want to have measures in place so that in the event that the temperature drops below 80* F, I can bring it back up quickly and safely.

I've heard of people adding heat lamps via a stand or clamps - does anyone have a link or something that they can provide for one of these fixtures? Any pictures or examples?

I'm not crazy about putting in an additional UTH because I'll lose my temperature gradient.

Are there any other methods for going about this? Suggestions? ... Criticisms?

Thank you all in advance!
