Watering Nepenthes: Brita Filter vs. Tap Water Flushing

Grower with N. sanguinea and N. 'Miranda' in terrarium asked if Brita-filtered water suffices (mom won't buy distilled daily).

Brita Limitations

Removes chlorine, heavy metals, debris – not calcium, magnesium, iron (hardness minerals).

Practical Nepenthes Watering

• Water like houseplants: when soil surface feels dry, top-water thoroughly, drain completely.
• Tap water is fine if flushed monthly with distilled water to prevent mineral buildup.
• Weekly watering typical indoors.
• Myth: Nepenthes require only distilled water.

Terrarium Note

Terrariums reduce evaporation – water less frequently. Ensure drainage.
