Nepenthes spathulata in Hot House: Wrinkled New Leaf Likely Transient, Not Heat Stress

Your Conditions Are Fine

Days 90s°F, nights 75°F, AC at 82°F, 5 hrs morning sun — well within tolerance. N. spathulata grows at Lelani Hapu'u Nursery in Hawaii with warmer summers.

That Wrinkled Leaf

Minor deformity on a new leaf = usually nothing. Could be brief humidity dip, watering inconsistency, or just developmental variation. The growth point is already making the next leaf — plant is active and healthy.

Don't Overmanage

• No need to artificially cool nights.
• Cool evening water helps but isn't critical.
• Don't cut pitchers — they're the plant's energy factories.
• Stability > fiddling. Nepenthes hate constant changes.

Signs of Real Heat Stress

Pitchers aborting en masse, basal dieback, no new leaves, root zone >90°F. You have none of these.
