This small tank was built for growing miniature high altitude orchid species from Papua New Guinea. Despite its extremely tropical location (~5 ̊S), due to lapse rate, temperatures at higher altitudes can be extremely cool. For example, in Laiagam in Enga Province, temperatures are often ~50 ̊F at night and rarely reach 70 ̊F during the day. Laiagam is approximately 2200 meters (7,217 feet) above sea level. Parts of New Guinea reach higher than 3000 m and have snow and glaciers capping the peaks. This tank is in Austin, Texas, where outdoor temperatures often exceed 105 ̊F.
