Some people prefer to add charcoal or a decorative layer at the very bottom of the drainage layer. One to two inches of drainage material can be placed on top of the substrates.
You can also use a drainage bag, which is a plastic bag with a hole in the bottom that you fill with water. This will allow the water to drain through the bag and into your substrate, but it’s not as effective as the drainage method described above.

Do you put rocks in the bottom of the terrarium?
To prevent plant roots from rotting, it is important to create drainage layers in terrarium containers. Start by putting a 2-inch layer of coarse gravel, sea glass, or beach stones in the bottom of the terrarium. This will act as a barrier between the soil and the water. Next, add 2 inches of fine gravel or sand to the top.
Add a few more inches to this layer, and then add a couple of inches more of finer gravel. Continue this process until you have created a drainage layer that is at least 3 inches deep. You can add more gravel if you need to, but be careful not to add too much, as this can lead to root rot and other problems.
If you are not sure how much you should add, start with a small amount and work your way up to a larger amount as needed. Be sure to keep the layers of gravel and sand in contact with each other so that the roots of your plants will not dry out and rot from the lack of moisture.
It is also a good idea to put a little bit of peat moss on top of each layer to help keep it moist and prevent it from drying out. Once your drainage is complete, you can place your plant into the container.
Do I need sand in my terrarium?
Sand and Charcoal for Drainage Your DIY terrarium will need a layer of sand and crushed charcoal to help with drainage so the plants don’t rot. If you’re learning how to make your own, a 1-in. layer of sand/charcoal mix is sufficient. You can also use a mix of 1/2 to 3/4 cup per gallon of water, depending on the size of the container and the type of plants you want to keep in it.
If you’re not sure how much to use, start with a small amount and work your way up to a larger amount as you become more familiar with the process. For example, if you have a 10-gallon container, you can use about 1 cup of charcoal for every 10 gallons. How to Make Your Own Terrarium Sand and charcoal are available at most home improvement stores, and they can be purchased in a variety of sizes and colors.
The best way to find the right size for your container is to measure the depth of your soil, then divide that number by 2.5 to get the number of square feet you need. Then, multiply that by the amount of soil you’ll be using in your DIY terra cotta.
Why is it important to have gravel at the bottom of a terrarium?
Gravel or Stones (The Bedrock) This layer is the foundation of your terrarium, and serves the purpose of the bedrock in channeling and storing water. If you use material that is large and non-uniform in shape, it will create spaces for your plants to grow in. You’ll want to make sure that your gravel or stones are large enough to allow for the growth of plants, but not so large that they block out the light.
If you’re using gravel, it should be at least 3/4 of an inch in diameter and 1/2 to 1 inch thick. For example, a 1-inch-thick piece of gravel would be a good size for a 2-foot-tall plant, while a 3-by-3-in. piece would work just fine.
Make sure you don’t use gravel that’s too soft or too hard, or you’ll end up with a plant that won’t be able to stand up to the weight of its own roots. Watering Your Terrarium Watering is a very important part of keeping your plant healthy and thriving. The best way to do this is to use a watering can, which you can purchase at most garden centers or garden supply stores.
Should a terrarium be airtight?
Terrariums are fine if they are airtight, but we suggest removing the lid periodically (about once a week or even daily) to allow fresh air to circulate through the terrarium.
Why do you need charcoal in a terrarium?
The charcoal helps absorb any sitting water and prevents odors and bacteria build-up. You can purchase moss by the bag at garden centers and craft stores. This will add an authentic forest look to your terrarium and it will prevent the soil from dripping into the water. Once the moss is in place, you’ll want to add a layer of soil to the bottom of the container. You can use any soil that you have on hand.
I like to use a mix of peat moss and vermiculite. If you don’t have any of these ingredients, then you will need to purchase some from your local garden center or craft store. Once you’ve added your soil, place the lid on the pot and let it sit for a few hours to allow the moisture to evaporate. After that, it’s time to move on to adding the other ingredients.
How deep should terrarium soil be?
To avoid over watering your plants, fill the bottom of the vessel with rocks to collect the water drainage. You can add a layer of soil for your plants. It should be 2 inches deep for the plants to root to, but not so deep that the roots are exposed to the air. Water your plants as soon as the soil dries out.
If you are watering more than once a day, you may need to add a little more water. You can also use a drip irrigation system if you have one, or you can use an automatic watering system like a sprinkler or a rain barrel.
