Troubleshooting Brown Sundews in Terrariums: Light, Acclimation, and Setup Issues

Older leaf browning after shipping/transplant is normal. Key issues: 2×20W CFL at 12hr may be insufficient—lights must be <12" from plants. Terrariums hinder light penetration and overheat in sun. Ensure mineral-free water, sphagnum-based media (add sand/perlite if granulated), no fertilizers. Allow weeks for acclimation; new growth should produce dew.
