North Window on spider plant

spider plant with north window

What's Happening

North-facing windows provide only 200-500 lux diffuse light - insufficient for spider plant growth. The spectral quality lacks the red and blue wavelengths required for photosynthesis and morphogenesis. Plants in north windows exhibit stunted growth, lack of offsets, and progressively smaller new leaves.

How to Fix It

  1. 1

    Install LED grow light 12-18 inches above plant for 12-14 hours daily

  2. 2

    Use cool white (6500K) bulbs to compensate for missing blue spectrum from north light

  3. 3

    Relocate to east or west window if possible

  4. 4

    Accept slower growth rate and reduced offset production in north locations

  5. 5

    Rotate to brighter location for 2 weeks every 2 months to maintain plant vigor

How to Prevent It

Avoid north-facing windows for spider plants unless supplemented with grow lights. Minimum acceptable light from north exposure requires 10-12 hours of full-spectrum LED supplementation daily.
