Hi carni-growers! Today I am doing this post to share with you my last project: a highland landscaped terrarium. The goal of this was really simple: have a really nice landscaped terrarium to keep it in my living room & have a highland room to keep my Heliamphora collection. So I bought an old exoterra terrarium (60cmx60cmx45cm : height x width x depth), and I built a ‘structure’ around it. So the goal was to increase the insulation, and have a nice terrarium box. This is the setup: 1) Watering Really basic system, with high pressure pump, nozzle, water level security (to avoid running the pump without water). 2) Temperature Night: 12-15°C Day: 23-27°C I don’t heat the tank (I don’t need it with the LED just over it), but I need to cool it. For this I use an aquarium chiller (hailea HC 130A) which is under the tank, in a furniture (built for the tank). Cold water goes into the terrarium with a pump, and then into the 3 heat sinks (with fans) and comes back to the chiller. I also made a water cooling unit with PVC pipes, and mesh fabric. The fabric is always wet, and the air is coming through thanks to 2 fans. So water is evaporating, and thus airflow is getting a bit colder. 3) Ventilation 3 fans for air flow, plus 2 fans for the water cooling unit. They are running during the day. I will adjust frequency according to the plants reaction during the next months. 4) Light I am using Led lighting. There is 8x20W COB led. Leds are cooled with heat sinks and fans. 5) Landscaping Walls are covered with polyurethane moss, cork oak, and black mesh fabric. So the mosses, and orchids will grow on it. I wanted something really natural, without pots, labels, etc. So everything is hidden (but all the labels are in place ^^). In the bottom there is Dibond aluminium base over a seedling plate to make a small water reserve (to avoid plant soaking in the water). On top I put some horticultural felt to keep moist under the post, and to bring some water for my water cooling unit. 6) Regulation system The most important part of this tank (because without it nothing can run automatically): the regulation system. I built it with an Arduino Mega board, with many electrical connections, and computer programing (my brother helped me for this part). So everything can be ‘ON’, or ‘OFF’, or ‘AUTO’. I can change the setup/timing really easily. In the next weeks, I will add a Bluetooth module to control it directly from my smartphone. 7) Plants (The really most important part ;) ) This is the list of actual plants in my tank, but I am still looking for some heliamphora and some Utricularia ORCHIDS: Barbosella cucullata Bromeliacée sp. Bulbophyllum barbigerum Cleisostoma scolopendrifolium Earina autumnalis Epidendrum porpax Lockhartia sp. Masdevallia erinacea Masdevallia nidifica Masdevallia pyxis Masdevallia striatella Neolauchea pulchella Neoregelia liliputiana Pleurothallis /lepenthes sp. Pleurothallis hemirhoda Pleurothallis picta Pleurothallis rodrigoi Pleurothallis sertularioides Pleurothallis tripterantha Pleurothallis viduata Psychopsiella limminghei Restrepia echo Restrepia sp. (en pot) Restrepia sp. X 6 (dont Restrepia elegans) Restrepia trichoglossa Restrepia vasquezii Stellis sp. CARNIVOROUS PLANTS: Catopsis berteroniana Heliamphora heterodoxa x minor Heliamphora huberi (Akopan Tepui) Heliamphora arenicola (Tramen Tepui) Heliamphora chimantensis (Chimanta Tepui, Venezuela) Heliamphora minor Heliamphora ciliata Heliamphora pulchella (Amuri Tepui, Venezuela) Heliamphora hispida (Cerro Neblina, Venezuela) Heliamphora x 'tequila' Cephalotus follicularis Utricularia tricolor Drosera adelae ORTHER: Paepalanthus tortilis Xyris sp. (Neblina) And then the pictures of the building and the terrarium: Global view : My old electrical system My old highland terrarium (5 years old) The new tank Insulation of the tank Backgroung making Global view of making Left side view Covering with black mesh fabric View from top Water cooling unit Soldering station Regulation system making Regulation system (almost finished) I will add more pictures later to show you the plant growth =) If you have any question feel free to ask me ☺ Cheers Benjamin (Sorry for my English, I am French ^^)
