The light scale
Scale in µmol/m²/s, linear from 0 to 800. Lux are read as daylight: 1 µmol/m²/s is about 54 lux.
- Very dim: up to 25
- Dim to medium: 25–100
- Bright, no direct midday sun: 100–300
- Some direct sun: 300–700
- Direct sun: above 700
Care
Propagation
Seed of Thaumatophyllum bipinnatifidum covered at twice its diameter emerged at 80–91 % in five media; covered at four times its diameter it emerged more slowly and, in two of the media, at only 18–22 %.
