I've had my snake plant for about eight months now and I'm still figuring out the watering schedule

I've had my snake plant for about eight months now and I'm still figuring out the watering schedule. Mine's in a terra cotta pot with cactus soil, but I keep second-guessing myself on how dry it should really get between waterings. I know they're supposed to be low-maintenance, but I'd love to hear how often others are actually watering theirs? I have a photo of mine if anyone wants to compare growth rates—the variegated sections seem to be spreading, which is exciting!
