Cactus
One of the downsides of growing houseplants can be keeping the environment humid enough to maintain the health of tropical plants, which often need jungle-like conditions to truly thrive. This is not a problem for cactus, as these desert plants appreciate dry air and average room temperatures. Although some sun is necessary for cactus health, many species can get by on three hours a day and supplementary lighting can help specimens living in north-facing windows.
