N. ventricosa × inermis

Treat like N. ventricosa—same window, same care. Grows slower but equally adaptable.

Heliamphora heterodoxa × minor

• Minimum humidity: ~50%. Short dips okay; sustained <50% = decline.
• Terrarium-free? Only part of year if humidity maintained. Windowsill usually too dry.
• Heat waves (90s°F): Survive with misting; growth slows. Greenhouse temps hit 90s daily in summer with misting.
