Growing Heliamphora on a Windowsill: The Double-Pot Method for Cool Roots

Heliamphora minor can thrive on a sunny windowsill in mild climates (like Hacienda Heights, CA) – but only if you protect its roots from heat. The secret: **double potting**.

How Double Potting Works

1. Place the planted pot inside a larger, **non-draining ceramic pot**.
2. The air gap insulates the inner pot from sun-heated sides.
3. Water only to runoff – never let water accumulate in the outer pot.

Why It Matters

Heliamphora roots are extremely heat-sensitive. In nature, they grow in cool, misty tepuis. The outer pot acts as a heat shield while the inner pot's surface gets light. A temporary humidity dome helps during acclimation, but gradual hardening off to ambient humidity is best.

With 70-75°F days and 60°F nights, your conditions are ideal – just add the double pot and bright light.
