These are models without complex automatic control systems. They are actually a terrarium or a flower showcase with the usual elementary lighting and ventilation system, usually located at the top of the model. Today, more and more often, in addition to these two components, orchidariums and flower showcases are equipped with a thermometer and a hygrometer, allowing you to see humidity and temperature indicators and accordingly change them by adjusting the ventilation schedule.
There is no talk of a general automatic control system, but the simplest devices simplify the task of creating ideal conditions for growing a collection of orchids. To create comfortable conditions, you need to monitor the plants and resort to small tricks.
In the simplest models, the temperature is lowered by airing or by installing them in rooms with reduced rates, air humidity is controlled by ventilation, by opening the doors or the “roof”, installing pallets and sponges and oases soaked in water.
More economical options are models for small collections. In simple models of orchidariums, plants are usually grown that are similar to each other not only in terms of temperature requirements, but also to lighting. It is impossible to place a separate collection in them, because there are no several levels of plant placement in them. There, for example, you can place oncidiums with Cattleya together, but not oncidiums with Wands and Phalaenopsis.
In the “multi-level” models of orchidariums, you can grow any of the indoor orchids – both the rarest and the most typical for residential premises, but capricious

Home orchidariums are always the most economical options, but not in every case they are the most modest. They are made from accessible materials by those who like to craft and experiment. It is better to independently build an orchidarium for those gardeners who have previously dealt with aquariums or terrariums (at least – backlit florariums), has at least minimal experience in organizing additional lighting and a stably humid environment for growing capricious plants.
It is better for beginners to first experiment with florariums, and only then try themselves with much more valuable orchids grown in special “indoor houses”.
Home orchidariums are variants of home-made flower showcases and florariums. They can be either large, designed for a collection, or created for a single orchid.
Most often, orchidariums are created on the basis of an aquarium, choosing sizes, shape, model, style to your taste and to your interior. Both frame and glued aquariums with one removable side wall and a glass thickness of 6 to 8 mm are suitable for orchidariums.
If the model of the aquarium is open, then the removable wall is replaced with a “cover” of plastic, acrylic, plexiglass (high wear resistance and transparency are important). You can also use large glass vases of an original form to create an orchidarium, especially if it is planned to place only a few miniature orchids in it.
Planning is a key success factor in creating home orchidariums. Disappointments and loss of plants can be avoided if you think in advance not only those additional elements that will be used in creating the orchidarium, but also the entire functional component.
The type and intensity of lighting, the method of mounting sensors or systems, the laying of communications, holes or gaps for ventilation, the mesh or frame for attaching plants – all this must be “calculated” in advance. Having carefully drawn up the plan and studied the features of the plant life support systems, one should not forget about moisture protection, safety measures when working with electrical devices and wiring, and additional decor.
There are several essential elements in home orchidariums:
Lighting system – special phytolamps, lamps for illumination of plants or, in extreme cases, fluorescent lamps (usually use standard 36 watt lamps), which create a full range of illumination for plants. Additional illumination is necessary for any orchidarium that is not located on the south window. For orchids, the lighting system is thought out so that the plants receive light in an amount of about 20,000 lux for photophilous species.
Ventilation system – openings that allow plants to breathe and provide a steady flow of fresh air or specially installed fans that provide continuous air renewal (they use special ventilation systems for plants and ordinary computer fans).
Communications – holes and channels for electrical wires and other functional elements.
Protective elements and fasteners – special “thresholds”, supports, coatings that hold the decor and plants at the attachment point, which make the composition inside the orchidarium stable and maintain the isolation of the orchidarium itself.
