Calathea: low light myth
Quick answer
Plant stores market Calatheas as 'low light' and 'low maintenance' plants, but this is a care myth. Calatheas require bright indirect light (1000-2500 lux) for vibrant foliage and healthy nyctinastic movement. Low light conditions cause etiolation, faded leaf patterns, slower growth, and weakened plants that appear 'fussy' or 'dying' when actually they're light-starved. This myth leads to overcompensation through excessive humidity interventions and frequent relocation, compounding plant stress.
Start here:
- 1. Relocate to bright indirect light near east or filtered west window, maintaining 1000-2500 lux
- 2. Supplement with full-spectrum grow lights 12-14 hours daily if natural light is insufficient

Ongoing Calathea notes
Position Calatheas in bright indirect light (near east/northeast windows with 1-2 hours gentle morning sun, or filtered west windows). Use light meter apps to verify 1000-2500 lux. Avoid placing more than 2-3 feet from windows in most indoor settings.
