Highland Nepenthes Terrarium: Night Cooling Solutions

Otto (Sweden) plans a highland Nepenthes tank (50×33×27 cm) with T5HO 2×24W (3300 lumens), computer fan for circulation, 88% humidity, 23°C day. Night temp stays at 23°C; frozen bottles drop it to 14°C but humidity crashes to 62%. Target: 10–13°C night / 80% humidity.

Another grower (not Jeff) replied: they grow highlanders at 25°C day / 18°C night, 70–75% RH with great results. At 17°C night, 65–70% RH is fine—plants tolerate lower night humidity if days are 80%. They use AC now, previously ice packs.

Good Growing!
