Nepenthes Judith Finn generally like bright light without much direct sun. About 50% sun or dappled shade is good. Plant grow lights often work well if they are broad spectrum and are kept just far enough away to prevent overheating or scorching. Sunburn usually appears as red or dead zones
on the upper most growth, facing the sun or light. Do not allow Nepenthes to dry out completely. They benefit from moist media and occasional flooding to wash away any accumulated salts. Use relatively clean water such as rain, distilled or purified water. Tap water can be used in many localities if the water is low in salts. Low levels of chlorine do not seem to be a problem. Nepenthes often tolerate low humidity, they usually stop making pitchers. Humid environments such as greenhouses
, terrariums or even tents made from sticks and clear plastic bags can provide the needed humidity. Be sure to provide some ventilation to prevent overheating and stagnant air. Many people put their plants outdoors during warm, humid weather. Some shade must be provided and bring the plant(s) indoors before temperatures drop below 50 degree F.
If you are growing
the plant where it cannot catch insects for long periods, you can add an occasional small insect such as a fly, a cockroach or a few very small insects to mature pitchers.
