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 107 ̊F.

For right now it's just a ten gallon. I will eventually upgrade to a larger tank.

The tank is specifically for Papua New Guinea orchids that come from 2000-3000 meters above sea level. Specifically, Dendrobium cuthbertsonii, dekockii, agathodaemonis, brevicaule, etc.

The cooling system is a Haier cube dorm fridge minus, well, the fridge. I put the evaporator coil from the fridge inside a ten gallon vert. The compressor and condenser coil are directly behind the tank.

The lighting is composed of six Cree XP-G high intensity LEDs mounted to aluminum heatsinks. They are driven by a 1000 mA Buckpuck driver and powered by a 24 Volt Potrans power supply.

Watering is accomplished by a standard MistKing system.

Air circulation is accomplished by a 60 mm ADDA waterproof DC fan.

The reservoir at the bottom of the tank (filled with distilled water) is warmed. The fan turns off, the compressor kicks on and voila, precipitation in a tank.

Eric, 75 during the day (which I will lower when I get a proper thermostat), then 48-52 at night (depending on compressor cycle).
 
call Tom at Golden Gate Orchids. I just visited him last week and he has got the best cuthbertsonii collection ever. hands down. now is their blooming season also..

10 gallon vertical I built for my desk at work in hellishly hot Austin, TX. I secured hardware cloth to a dorm fridge evaporator (the compressor and condenser are outside the tank and not pictured). Daytime temps are around 71-73 deg. F (21.7-22.8 deg. C), night temps dip down to 48 deg. F (9 deg. C). I water with distilled water using a MistKing system. Lighting is provided by six Cree XP-G R5 LEDs driven at 1 amp each with 40 degree reflectors.
 
Great set up!

It just boggles my mind that while I deal with trying to keep orchids warm, others are trying to keep their plants cooler =)
 
Chris, this is fantastic, and probably the coolest thing I have seen in a while. I would love to try it for certain high-altitude Ddendrobates species. And orchids. And anything else. A big, 75 gallomn terarium. dream on, Brian
 
Hahah Eric, yeah, it's in a laboratory with several million dollars in instrumentation that runs 24/7, power is not a concern.
