There are a lot of factors to keep in mind when choosing what goes in a terrarium. These variables include the types of terrarium plants that you choose, the size of your terrarium and more. But there is one very important thing that can make all the difference: your terrarium design.
The main question that most people have is what goes in a closed terrarium. The answer is simple: light. Any kind of plant will do as long as it gets plenty of light. Plants that are native to the Amazon rainforest do best in direct sunlight, while others prefer to stay in a dark, somewhat cool environment. You will need to experiment with your terrarium plants in order to find out what conditions best suit them.
Some kinds of plants do better in potting soil, while others prefer gravel or bark to be planted in. Most tropical plants can thrive in both kinds of medium, but you might find that your DIY terrarium plants do not do so well in either one. If this is the case, then you should consider repotting your plants instead of moving them to a new location.
You also have a choice of what goes in a DIY terrariums. Most African violet plants can do well in either a potting soil or gravel/stone tray. However, you may find that other succulents, such as Java ferns or some floating plants, do better in the one place. This is because they have adapted to their new home quite well and are therefore more able to survive in that environment.
As far as what goes in a terrarium that has no direct sunlight, the answer is pretty self explanatory. Water is your biggest concern. Many plants prefer water as well as oxygen, so you will need to make sure you keep the terrarium well watered. However, make sure you never drown the plants with water, as this is very hazardous for the health of the plant and can even result in death. Instead, keep the water in the terrarium’s reservoir and access it by placing a small tray with water underneath the terrarium.
So what goes in a DIY terrarium that has direct sunlight? Again, the answer is pretty simple – the plant needs a source of light to photosynthesize. Many plants such as Java ferns do really well in this sort of environment and do extremely well when placed in a terrarium with some gravel or pebbles as the base. However, there are other plants such as Java Ferns that do not do well at all in direct sunlight, so make sure you do not place Java Ferns in a terrarium with direct sunlight.
What goes in a terrarium that has both direct and indirect sunlight? If you are planning on placing live plants in your terrarium, it is best to purchase a kit that contains both a planting medium such as gravel or perlite and plant food, which can be purchased separately. If you are planning on using soil or potting soil, then it is best to use a type of potting soil that will not hold water, but also has enough drainage to prevent root rot. This will also help prevent the roots of the plants from becoming drowned while they are growing.
What goes in a terrarium that has both open and closed terrariums? In this case, the plants will need to be properly cared for if they are going to survive the exposure to both sunlight and shade. If you have purchased a kit with both the planting medium and plant food included, then make sure you follow the directions carefully so that your plants will get the proper care. This way, you will also avoid the problems that might occur when only one of the materials is used.
