Watching your succulents stretch into pale, weak shadows of their former selves?ย Etiolationย (stretching) indicates your plants are starving for light. Most succulents needย 2,000-3,000 foot-candlesย of light intensityโequivalent to bright, direct sunlight. Thisย definitive succulent grow light guideย gives you the exact specifications professional growers use to maintain picture-perfect plants.

The Succulent Stretching Crisis: Understanding the Problem
Why Windows Fail Succulents:

- North/east windows:ย 200-500 foot-candles (causes severe stretching)
- Window film/glass:ย Blocks 40-60% of crucial UV and infrared light

- Red light (600-700nm):ย 20-30% for color enhancement
2. Intensity & Duration Mastery
- Light intensity:ย 2,000-3,000 lux minimum
- Daily duration:ย 12-14 hours consistently
