Hi Minh, I use a terrarium, but I don't have a chiller its in my room, my room is naturally highland conditions, so i have no fancy machines or anything, just a bottle to mist and some lights thats it. thanks for the compliment.
Aristolochioides isn't necessarily ultrahighland but it highalnd its a bit pickier than most. But in this cross you get spectabilis aswell. Spectabilis is a very easy highlander, so the cross spectabilis x aristolochioides, is easier than a pure aristolochioides.
