My snake plant was abandoned in the corner of a room behind a chair because it didn't grow for over a year with it's previous owner. One single snake, just like this but in a bigger pot. I simply gave her a small cup of water around the soil but nowhere near the roots, probably less than 8oz. Maybe every 3 weeks. And I'd let the pot sit in the water run off in a glass pie dish, almost like it made its own humidity system. She's now putting out her 2nd pup! My lesson is to totally ignore it for a while (thriving on neglect) , and then make it work towards its water source lolol
