Optimizing Fluorescent Lighting for Indoor Nepenthes: Intensity, Spectrum, and Leaf Burn Prevention

Optimizing Fluorescent Lighting for Indoor Nepenthes: Intensity, Spectrum, and Leaf Burn Prevention

Too Much Light?

Small plants: yellow leaves = light too intense. Move fixture back.

Large plants: top leaves get more light than lower. If upper leaves yellow, raise lights slightly (trade-off: lower leaves get less).

Spectrum Preference

Red light promotes flowering; blue promotes foliage. Cool white fluorescents (balanced) outperform plant bulbs for pitcher production.

East Window Supplement

1.5 hours eastern sun helps marginally. Fine-tune throughout season.

Good growing!
