But I'd still like to streamline things so I don't need to have her too involved so as to not make the whole proposition too much of a burden. She's already done so much for me and all that.

And fwiw, the snake wouldn't be moving directly to this type of enclosure, since it'll be in a quarantine tub first and then probably grown out a bit in my currently empty 30 gallon. So even post-arrival I'll have ample time to fine-tune everything.
Um, no...you don't want to try to spread silicone aquarium sealant on flat surfaces...no, no, no...it's used in the corners, just like in actual aquariums. That's all- don't even go there.

Look into the pond sealants, perhaps, for what you're thinking- & again, I've never used them, but someone else here mentioned them a while back, if you can search that out. I don't remember who or how they used it, only that I became aware of such products att & thought they looked "interesting". (I enjoy hardware stores & thinking 'outside the box'.)
