Give Venus fly traps as much light as you can. Full direct sunlight at least four hours a day is best, though Venus fly traps can flourish under strong artificial lighting as well. Water them with “pure” water (low in mineral content), either distilled, rain water, or other water that has a low concentration of dissolved solids. For optimal growth, do not keep Venus fly traps sitting in water. They prefer to have their soil always damp, never dry, and not too wet for too long. And plant Venus flytraps in a proper mix of a nutrient-poor medium. Most people use peat, sphagnum moss, sand and perlite in some combination.
