I finally finished my HL setup Oh gosh, how much I have dreamed about this! The terrarium (53L) is placed in our cellar. The lighting is 2X18W lamps and the heater is 50W aquarium heater. The cellar stays all the time 12-14C so I only have to heat it at day.
Since I have been stuck with lowland species for 2 years I have no idea what temps some highlands can handle. Other likes it warmer and other colder.
Day temps: 22-24C (72-75F)
Night temps: 12-14C (54-57F)
I'd like to have easy and beautiful highland species that stays rather small. From what I have read, N. spectabilis and N. spectabilis X aristolochioides would be nice
