Mexican Pinguicula Light and Water Requirements: Debunking Dormancy Myths

Pinguicula agnata losing dew and yellowing lower leaves = insufficient light. All CP need high light; butterworts are shade-tolerant but still require direct sun or close artificial light. Mucilage production is photosynthesis-dependent. Halogen lights fail—they lack blue spectrum. Use 5000-6500K fluorescent (CFL or tubes). Water when soil feels dry; slight tray water OK. Desktop lighting involves tradeoffs: cheap+efficient=ugly; attractive+efficient=expensive.
