The ideal placement of your terrarium should be within 5 feet of a window. South-facing windows will be best for cacti and succulents because the south side receives the most amount of sunlight. Terrarium plants that prefer indirect sunlight will be best placed near a south or west-facing window.
As such, open and closed terrariums require different plans. Open terrarium plants prefer circulating air and a drier environment. Plants such as aloe, hens and chicks, cacti, and air plant are best for this. On the other hand, closed terrariums thrive in a closed space with more moisture.
To start assembling the terrarium, begin with a drainage layer of pebbles or vermiculite layers, then add activated charcoal on top. You can also cover the activate charcoal with mesh fabric to prevent root rot. Then top with soil, polymer hydration crystals (optional), and the plants themselves.
Charcoal is an important element in a terrarium because it helps remove toxins and odors. If you don’t have charcoal, you can still make a terrarium, but you’ll need to to take extra steps to ensure your plants remain healthy and that the environment inside your terrarium remains clean and odor-free.
Most plants that are suitable for terrariums do not require extremely bright light. If placed in direct sun or extremely bright light, terrarium glass can act as a magnifier and burn the plants. … Most plants can’t tolerate this kind of heat, so it’s best to keep terrariums out of the direct sun.
In general, for terrariums with a normal, loose-fitting glass lid, it most likely will need to be watered a small amount every 3 months. For a terrarium with a cork, rubber, or tight glass enclosure, it can stay closed without needing any water at all.
Keep in mind, however, that not all containers are suited for being repurposed into terrariums. Ideally, a closed container with a lid will encourage the humidity that helps your plants thrive. … We recommend plants like tropical ferns, mosses, Selaginella, Peperomia, Cryptanthus, and air plants.
Moisture from the soil and plants evaporate in the slightly higher temperature inside the terrarium. This water vapour condenses on the walls of the glass container, and falls back to the plants and soil below. … The moisture in closed terrariums is constantly recycled, so they need minimal care.
Terrarium Soil Mixes
Soil components for blending are standard potting soil, sandy potting soil (often labeled cactus soil), soil-less potting mix, perlite, peat moss, grit or sharp sand, humus and horticultural charcoal. The proportion and components used determine the characteristics of the resulting soil mix.

Sphagnum Moss is true terrarium staple. It has huge utility thanks to its incredible water retention capabilities – making it just as effective a substrate as a carpeting moss. Not all that surprising considering its natural role of forming peats bogs in the wild through storing water.
Lizards, which live in open spaces and on the ground, are well suited for horizontal terrariums. Cubic terrariums are good for many lizard types, including those which often dig holes and go under the ground in the wild.
The best type of artificial lighting for a terrarium is fluorescent or LED lighting like this. Compact fluorescent bulbs (CFL) are also a choice of lighting for your terrarium plants. Please note that general household bulbs will not keep your plants alive and growing.
Air plants grow well displayed in terrariums, which are clear glass or plastic containers filled with small plants. Often terrariums are tightly closed, but my light-bulb shaped container has one side completely open to help with air circulation.
Container Gardens/Terrariums/Houseplant: Aloe vera will grow well in a container garden, terrarium or as a houseplant. … Aloe vera is a terrestrial succulent and should be planted in the substrate. Aloe vera will grow from 6-12″, so keep this in mind when planting Aloe vera in your desert vivarium.
A terrarium is an ideal environment to sprout grass seed, either as decor or as a teaching tool for children. It’s also a viable way to grow food grasses, such as wheatgrass, indoors, creating a readily available supply any time you like.
These plants should have night temperatures of about 50 to 55 degrees F. Locations with these temperatures may be difficult to find in the home, but in the winter, when plants are placed on a windowsill close to the glass with the drapes pulled behind them, a pocket of cool air will develop.
If you have a closed terrarium and it’s fogging, it will be mainly caused by too much water and differences of temperature inside and outside of the terrarium. If for example, direct sunlight hits the closed glass terrarium, the temperature inside the terrarium becomes too high.
