Peace Lily in a Windowless Office: LED Light, Watering, and Pot Size Solutions

Current Issues

• Yellow/brown floppy leaves, black tips.
• No natural light; only LED grow strips (red/blue/green) 4–6 feet away, 12 hrs/day.
• Pot too large—plant cannot become rootbound, so it won't flower.

Fixes

1. Remove yellow leaves at base; they won't recover.
2. Light: Fluorescent tubes (cool + warm white) 12 inches above plant, 12+ hrs/day, are more reliable than untested LEDs. If keeping LEDs, move plants as close as possible (intensity drops sharply with distance).
3. Pot: Do not repot. If the plastic pot is ugly, slip it into a decorative cachepot. The plant must fill its pot with roots to bloom.
4. Water: Wait until soil is dry 1–2 inches deep. Use pot weight as gauge.
5. Misting: Unnecessary; doesn't raise humidity.

LED Specifics

• Reflecting light from below does nothing—photosensors are on top of leaves.
• Mirrors beside plants can redirect light to lower leaf surfaces.
• Closer = better intensity.

Outlook

With bright enough light and a snug pot, new leaves will be firm and flowering may occur. Existing soft leaves stay soft but won't harm the plant.
