How do you make a closed terrarium? The first thing you have to do is purchase or make some terrarium plants. Make sure that the plants are very small and they don’t take up too much space in your terrarium design. If you are using rocks, you can place them on a flat surface instead of on the ground. The rocks will help support your terrarium plants and they will also keep the water of the terrarium and the plants from standing on the gravel.

How to create a closed terrarium using pebbles: For a closed, pebbled terrarium, you will need a container of large and flat rocks. The rocks should be about an inch thick. Add some activated charcoal to the base of your container. Next, add a shallow dish with water and some medium-sized succulent terrarium plants (at least ten, but up to twenty) in a single layer above the rocks.

The container should be a shallow tray. You can use any container that has a flat bottom and is big enough for your initial plants and the succulent terrarium plants. Start placing your first plants into the terrarium, keeping them in the dish with water. Start putting the medium-sized terrarium plants in one layer right over the rocks. These medium-sized terrarium plants should not be placed directly on the rock.

When the plants are well placed in the terrarium, you can now place your seeds and propagate into your own species of plants. Remember to keep the container of rocks with the air plants in a shady place. If the terrarium plants do not tolerate being in direct sunlight, they will quickly spread all over your terrarium, killing most of your initial hardy plants. The best way to set up your terrarium is to have it in an indirect, south-facing part of the house. If the indirect sunlight cannot be afforded, you can always place your terrarium on a sunny windowsill or on a sunny day when there is no breeze.

You can always add some medium-sized food to your terrarium, such as pellets or seeds. It is also possible to use vermiculite or perlite as a substitute for the potting soil in your terrarium. There are many other closed terrarium supplies that you can find at hardware or gardening stores. These include wires, tubing, aquarium dosing pumps, thermometers and test strips.

For safety reasons, you should keep your plants in a sealed terrarium. To achieve this, you can have a clear plastic lid with either a clear top or with a net or a mesh top over a smaller clear plastic lid. On the inside of the net or mesh lid is another piece of glass or acrylic that fits tightly over the lid and keeps the plants from rolling out of the top. In addition, you can use a small pump to circulate the air in your closed terrarium to keep the lid closed and the plants from moving out of the top.

There are a couple of special closed terrarium supplies that I would suggest you purchase if you are not afraid of introducing some new plants into your system. One of these is called activated charcoal. This special kind of charcoal is typically used for baking and to keep foods safely stored at low temperatures. Activated charcoal is often used in closed systems, but it is particularly good at controlling algae growth. Having a little activated charcoal in your soil will help prevent the dreaded brown algae disease.

If you have a filter on your terrarium, you may want to get creative and use that filter to add extra dimension to your closed system. Have you ever seen fish tanks that have gravel layers in the bottom to give the fish additional nutrients? You can easily do this with a closed system by making the gravel a part of your substrate. The only problem with this is that you have to constantly water the gravel. You can also make the substrate into a substrate for your plants to grow on instead.
