Universal light requirements
Quick answer
For Universal, light requirements come down to this: CAM (Crassulacean Acid Metabolism) photosynthesis allows succulents to keep stomata closed during daytime hours and open them at night, storing carbon dioxide as malic acid to be used during daylight for photosynthesis. This adaptation reduces water loss through transpiration by up to 90% compared to C3 plants.
Start here:
- 1. 1. Accept that succulents grow more slowly than typical houseplants due to CAM metabolism
- 2. 2. Provide bright light during day to fuel photosynthesis after nighttime CO2 storage
What light requirements mean for Universal

This adaptation reduces water loss through transpiration by up to 90% compared to C3 plants.
How to meet Universal light requirements
- 1
1. Accept that succulents grow more slowly than typical houseplants due to CAM metabolism
- 2
2. Provide bright light during day to fuel photosynthesis after nighttime CO2 storage
- 3
3. Water in evening or early morning to align with natural CAM cycle
- 4
4. Maintain temperatures between 50-85°F for optimal CAM function
Keeping Universal in range
Understand your succulent's native climate — CAM idling occurs when night temperatures remain high, causing stomata to remain closed day and night, recycling CO2 from respiration.
