A Pennsylvania grower's N. ventricosa (bought April) produced one leaf, no pitchers after moving outdoors in 95°F heat under a rhododendron (6–7 hrs sun). Leaves reddened (good light). The expert attributes failure to repeated environmental shocks: low light indoors → intense outdoor light/heat → humidity/temperature swings. Red leaves = adequate light, but young tendrils may have burned. Recommends: bring indoors to stable south window + supplemental fluorescent, keep stationary, allow weeks/months to recover. Stable environment is key.
