They love being in shade or with dappled light, loves being root bound. During winter, watering is lesser, well, since all my spider plants are outdoors so easy enough to dry out after the occasional rain. But this winter season, it has been unusually dry, so I do one heavy watering once every two weeks.
Signs of overwatering, leaf tips turning brown, and if too much light, leaves turning too white and transparent ..
I remember seeing a very large spider plant at a friend's home, grown in a hanging basket under an awning, and it is just growing so profusely with lots of babies cascading. I used to trim the babies a lot, and seeing those cascading babies, I let the babies in my plants hanging on longer
