It is advisable to connect all sources of heating through an automatic temperature controller. thermal relay. This will avoid overheating. terrarium, especially during the hot summer months. Any temperature switch consists of a temperature sensor, which is a thermistor or contact thermometer, and a device for setting the required temperature.
Domestic thermal relay of the Danio type, TL-3-1 can be purchased on the Bird Market for 100. 200 rubles. There is also a thermal relay company Hagen (Germany). The temperature sensor is located inside the terrarium in the place where it is necessary to maintain the desired temperature.
Lighting. It is necessary to illuminate any terrarium containing various species of tree reptiles: chameleons, day geckos of the genus Phelsuma, tree snakes of the genera Boiga, Achaetula, iguanas. For most snakes such as pythons, snakes, milk snakes and soil geckos (scink geckos, geckos of the genera Eublepharis, Hemitheconyx, Goniurozaurus, Coleonyx) lighting can be neglected. If the terrarium is planted with living plants, good lighting is necessary for their normal growth. Usually, daylight lamps of the LB type (15, 20, 40 W) are installed, corresponding in power and length to the size of the terrarium. For plant growth, it is useful to use a block of four fluorescent lamps, which are located at the top of the terrarium, if it is made of transparent glass or plastic. All woody daytime species need regular ultraviolet (UV) radiation. For them, one of the lamps in the lighting unit can be replaced with a lamp of the ReptiGlo (Hagen) type, which has a UV part of the spectrum. Thus, the problem of UV exposure will be solved. It should be noted that any source of UV radiation must be located on the terrarium grid or directly inside the terrarium, since glass retains most of the UV spectrum. Daylight hours should last from 8 to 12 hours, depending on the time of year.
Glass, plastic (organic glass), wood are suitable for the manufacture of a terrarium. Plexiglass terrariums are small in weight, it is convenient to install heating and lighting systems on them (plexiglass is easily drilled), and, of course, not as fragile as glass structures. However, there are drawbacks: the cost of plexiglass compared to ordinary glass is quite high, in addition, over time, the plexiglass is covered with a network of small scratches, "becomes cloudy" and can be slightly deformed. Wooden terrariums are comfortable, but it’s hard to maintain the required humidity level. In addition, wood and plywood warp from moisture. This can be prevented by covering the wooden parts with several layers of furniture varnish. The optimal solution is to use as a material either one glass or a combination of glass and plexiglass.
The technology of manufacturing glass terrariums
For gluing glass terrariums, only silicone-containing adhesives-sealants can be used, for example, Silicone-BB, 911. The abstract should indicate that the adhesive can be used for gluing frameless glass structures. The sealant is available in the form of l cylinders. The cost ranges from 60 to 150 rubles, depending on the brand and company. First, it is best to fill the sealant in one or more plastic disposable syringes without needles. In such packaging, it can be stored in the refrigerator for several days. At the same time, a drop of sealant should protrude from the opening of the syringe, otherwise it will harden and clog the syringe. The glass or ceramic surfaces to be bonded must be degreased with alcohol or acetone before applying the sealant, and the metal surfaces must be cleaned with a sandpaper or file before degreasing. After applying the sealant, the surfaces of the terrarium are pressed against each other for a day using a press or glued with adhesive tape (scotch tape). In the manufacture of a terrarium, all walls are first cut out with a glass cutter (cutting accuracy of 1 mm!), Then the walls with ventilation holes are glued together (Fig. 1).
