Nepenthes copelandii Fails to Pitcher Due to Low Light

my plant

A Zone 7 grower's N. copelandii (intermediate) lost pitchers after summer purchase. Hangs in a basket near a window with a single CFL.

Diagnosis

Insufficient light. Nepenthes need far more light than ivy to pitcher, produce nectar/fluid, and digest. Author's success: 3 banks of 40W shop lights (18,000 lumens) 4–6 inches away. Hanging basket too high, window too dim. Light is key – too little starves the plant.
