Can I keep a cactus indoors?
user
To keep a cactus alive indoors, I’d recommend two conditions:  one, it must have a well-lit spot with enough light for the plant to make food, and two, it must be kept warm enough so that the cactus doesn’t freeze at night.  If you live in a very cold climate, it might be necessary to light the cactus for several hours in the evening as well as morning.
