Care for a Heliamphora minor (Sun Pitcher), provide bright light, cool temperatures, and well-draining substrate with high humidity. Use only mineral-free water.

Light: Heliamphora minor needs bright, direct sunlight or strong grow lights (12-16 hours a day) for healthy growth and vibrant colors.

Temperature: They thrive in cool, humid environments. Daytime temperatures are between 60-80°F, with nighttime temperatures slightly cooler 45-60°F. 

Water: Use only mineral-free water, such as distilled, rainwater, or reverse osmosis water. Keep the substrate consistently moist but not waterlogged. You can water from above, allowing water to drain through the pot. 

Substrate: An airy, well-draining mix is crucial for Heliamphora's roots.Use a mix of long-fiber sphagnum moss and perlite, or pumice/lava rock.

Humidity:  High humidity is essential. Misting the plant with pure water regularly can help maintain humidity.

Fertilization/Feeding: You can feed them insects or use Maxsea once a month, apply in the pitchers/leaves, about 1/4 teaspoon per gallon of water.
