Greenhouses
Most greenhouses that are already established for the cultivation of tropical plants (high humidity and stabilized temperatures) make ideal environments in which to grow Nepenthes. Due to their different requirements, highland and lowland species are best maintained in separate greenhouses (see temperature, below).

Terrariums
An aquarium or similar glass tank can make an excellent growing chamber for keeping a small collection of tropical plants and is surprisingly easy to maintain. Nepenthes thrive in the high humidity that a terrarium provides and most species will rapidly outgrow even large tanks. Lighting is best provided by several fluorescent tubes (any broad-spectrum brand works well) positioned directly on the lid of the tank.

Houseplants
An increasing number of plant collectors have been finding that, with proper care, many Nepenthes may be grown as houseplants on sunny windowsills. In addition to catching a few annoying houseflies, a healthy plant with pitchers makes a fascinating addition to the windowsill garden. Those species of Nepenthes which can tolerate relatively dry air and temperature fluctuations seem to perform best indoors. Good candidates include: N. alata, N. maxima, N. tobaica, N. ventricosa, and various hybrids. It is very important to insure that plants grown indoors receive adequate light and humidity. Plants should only be kept on bright windowsills which receive a minimum of 3 hours direct sun each day. Additional humidity can be provided by frequent spraying with pure water.
