Because of where I live, I have hot lowland summers and the winters are too cold for lowlanders. My summer temps are usually about 36C (97F), and the summer nights are about 27C (81F). I want to give a highland nep a try, but I don't want to buy a cooling setup. I heard that ventricosas and boschiana can survive those temps, and so do veitchii crosses. What nep should I choose?
