grow light burn on Thai Constellation
Quick answer
If your Thai Constellation has grow light burn, the most likely cause is: Thai Constellation (Monstera deliciosa 'Thai Constellation') variegated white leaf sectors lack chlorophyll and cannot conduct photosynthesis, causing these tissues to heat rapidly under direct light exposure. White sectors reach temperatures 15-25F above ambient within 10-15 minutes under high-intensity grow lights or direct sun, leading to photooxidative damage and cellular collapse in the absence of photoprotective pigments.
Start here:
- 1. Move plant immediately to lower light area if white leaf sectors appear pink, brown, or translucent
- 2. Trim severely damaged white sectors with sterile scissors, cutting 1/4 inch into green tissue

How to reverse grow light burn on Thai Constellation
- 1
Move plant immediately to lower light area if white leaf sectors appear pink, brown, or translucent
- 2
Trim severely damaged white sectors with sterile scissors, cutting 1/4 inch into green tissue
- 3
Reduce LED intensity by 20-30% increments over 1-2 weeks to find tolerance threshold
- 4
Position grow lights 24-36 inches above canopy for standard LEDs, 18-24 inches for lower-wattage LEDs
- 5
Monitor white sectors for 1-2 weeks after light adjustment to confirm recovery
- 6
Avoid relocating between very different light environments more than once per month
Keep grow light burn off this Thai Constellation
Position Thai Constellation 24-36 inches below LED grow lights rated 200-400W; use 6500K full-spectrum lights at 40-60% intensity initially; maintain ambient temperature below 80F; never expose white variegated sectors to direct unfiltered afternoon sun.
