Always In Humid Hide

[Bogertophis]

I always am so scared of mold/fungus growing also. I'm so OCD about this I fear. LOL.

I know what you mean...it's one reason I'm glad I don't keep BPs, or snakes that need similar warmth + humidity.

For what it's worth, I've tried (in the past & for a couple years) a pair of plastic enclosures & had mold issues in the substrate. I live in a fairly humid state, & I even
drilled many extra vent holes but still had the issue. Also, I just didn't like using "plastic" housing, & these were one of the few made of HDPE plastic. (ie. 'food safe')

The thing about HDPE plastic is that even that isn't supposed to be re-heated (when used for food) since it does break down & can leach or off-gas carcinogens...but
most everyone in the BP-community is so hooked on plastic enclosures for BPs & it's just too "inconvenient" to consider this issue... To me, glass is safer...it's inert
when heated, & disinfects easier (plastic scratches). The plastics can also sag a little over time (from the constant heating).

You'll have to make up your own mind...nothing is perfect.
