Is it Necessary?

[Hamsnacks]

you need to get more creative. buy a terra cotta planter big enough, make a hole. ~$15.

this isn't africa tho, and they're not in the wild. they're pets. there's no benefit to dropping temps.

also, how does "extra" vitamin D do anything for a nocturnal animal??? there's no basis for that at all, and there is no science proving positive or negative. here is a study done on captive ball pythons showing no correlation between exposure to vitamin D and how well they absorbed calcium (the biological process vitamin D is used for).

i cover 3 sides to almost all my snakes enclosures. whatever sunlight makes it into their tubs is plenty.

To each their own I guess lol, nothing against your suggestions, pretty funny and creative not going to lie.

Not here to argue, but you might want to do a bit more research on Vitamin D and animals, your link is from 2013, Nocturnal animals just means they are more active at night. The Moon reflects UV light, BPs get UV light no matter what lol, they also get it from their food, but now compare a wild mouse vs a captivity mouse, is that mouse getting exposed to UV enough, does it have enough vitamins for your BP? Just something to think about.
The debate is, is UV really beneficial or not, since I am not giving my snakes UV at night, mind as well give them it during the day while they are in their hides, whether they get any or not, won't harm them in anyway. If you read this link, its interesting, there may be signs that extra Vitamin D can be transferred to the eggs of a female BP.

Good Luck on your snakes! All the best. Like I said not here to argue but a good debate.
