How to Assess Your Home's Light Conditions
Here's our simple hand test method to determine your light levels:
The Hand Test: Stand in your chosen spot around midday and hold your hand about 30cm above the floor:
- Strong shadow with defined edges = Bright direct light
- Soft, fuzzy shadow = Medium indirect light
- Barely visible shadow = Low light
- No shadow = Very low light (consider artificial lighting)
Different Types of Light Exposure
Bright Direct Light
Perfect for sun-loving plants like cacti and certain rare plants. Typically found:
- Within 30cm of south-facing windows
- On sunny windowsills
- In conservatories
Bright Indirect Light
Ideal for many tropical plants like Monstera and Ficus. Found in:
- 1-2 metres from south-facing windows
- Near east or west-facing windows
- Bright rooms away from direct sun
