It’s not very successful to grow cacti in humid environments, but they can grow in terrariums. Make sure you pick a container that doesn’t have a lid. If the lid were on, the humidity would be much higher. If you want to grow a succulent in a greenhouse, you will need to use a humidifier to keep it from drying out.
You can use an air conditioner, but it will take a while for the air to get to the plants. If you are growing in an area with a lot of humidity, it may be a good idea to have a fan blowing on your plants to help keep them moist.

Are cactus good for closed terrariums?

How to Grow Cactus in a Terrarium Cactus can be grown indoors or outdoors, depending on what you want to do with them. If you’re going to grow them indoors, it’s best to choose plants that are small enough to fit into a small space.
The smaller the plant, the more room you have to work with, and the easier it will be to keep the plants healthy and happy. You can choose from a wide variety of plants, including succulents, daffodils, lilies, chrysanthemums and more. Some of the most popular plants for indoor growing include: cattails, daisies, hydrangeas, hibiscus, magnolias, roses, sunflowers, tulips, water lily and many, many more!

How do you take care of a cactus in a terrarium?
Between watering, allow your cactus to get bone-dry. When the soil feels completely dry to the touch, give it water about every 3 – 6 weeks. You can poke the cacti with a stick to see if it is thirsty. If it doesn’t move, it’s thirsty.
If you want to add a little more moisture to your soil, you can add 1/2 cup of peat moss per 1,000 sq. ft. of soil. This will increase the moisture content by about 1-2% per year, but it will take a few years for this to have an effect.
How do you make a cactus terrarium for a fish tank?
The bottom of the aquarium should be lined with two to three inches of pebbles. Four to six inches of commercially available cacti soil or a mixture of equal parts potting soil and coarse sand can be spread. The cactus will get good drainage from this. Next, fill the tank with water.
Add a few drops of aquarium salt to the water to help prevent algae from forming. You can also add a small amount of calcium carbonate (available at your local fish store) to your aquarium water if you don’t already have it.
If you do not have any of these items on hand, you can purchase them at a pet supply store or online. Once your tank is filled, place it in a sunny location away from direct sunlight for at least two weeks.
During this time, the plants will begin to grow, and you will be able to see the results of your efforts.
