I will say that this thread managed to get me curious...I'm not that familiar with grow tents, and after looking at some, what I COULD imagine using one for is a sort
of exercise "play-pen" for my big rat snakes. To install various interconnected branches or bamboo poles & give them some time to stretch out for a few hours a day,
and without them getting into trouble. (Rat snakes are generally great for clearing shelves!)

It would have easy clean up from drinking water or other 'spills', & it appears you could "lock" the zipper pulls together, though there'd still be some 'wiggle room' so
I'd just never leave a snake "home alone" this way. I know I've seen some open-air screen cages designed for reptiles to get some sun in...just never thought about
using a grow tent w/ indoor lighting.
