Stonecrops Sedum spp. Cacti and succulents generally are easy-to-grow plants that do not have a long list of requirements. One of the few requirements they have, though, can be difficult to provide indoors. They require light levels at a minimum of 1, foot-candles to survive. Jungle cacti, like the Christmas cactus Schlumbergera truncata , can be maintained with foot-candles, but thrive with 1, foot-candles. A south-facing window may provide enough light, but where this is inconvenient or impossible, cacti and succulents can be placed under grow lights to help meet their light exposure needs.
If you notice that your cactus has discolored, dry, or drooping leaves or segments, there are a number of possibilities for what could be bothering it. First diagnose the problem and give it the proper immediate care. Then take steps to give your cactus the best chance for long-term survival by providing it the appropriate soil, light, and environmental conditions. If the cactus seems shrunken, wrinkled, or wilting, give it water. If the soil is not dry, move the pot to an area where the cactus can get more sun. If the cactus is turning yellow or brown, it is getting too much sunlight and you should move it into a spot with better shade. Cut away any brown or black parts of the cactus to prevent rot from spreading.

Incandescent lights are good for lighting up a room or growing low-light houseplants, such as vines, ferns or dracaenas. They have limited utility for growing plants with higher light requirements.
Cacti are prized for their ability to thrive in full, hot sunshine and survive periods of extended drought. Because they need little watering, they are often cultivated as houseplants. Along with a little water, however, cacti need a lot of sunlight, which is something that is more difficult to come by indoors. For this reason, many home gardeners choose to grow their cactus plants under artificial lightening. Florescent lighting is a good choice for growing plants indoors, according to the University of Missouri Extension.
