There's something captivating about terrariums. Like ships in a bottle, or snow globes, they offer up a miniature world you can easily get lost in.  However, what sets terrariums apart is the fact they're self-sustaining ecosystems. Despite being small, these pockets of organic life can totally transform a room. To help you find the right one for you, we've a compiled a list of our picks for the Best DIY Terrarium Kits (plus a few classes thrown in for good measure). Time to get those fingers green, and build one from the soil up!

Spruce up your space with a Terrarium Kit

So what exactly is a terrarium? Simply put, terrariums are mini ecosystems created in glass or plastic vessels containing plants, soil, minerals and a host of other things. The idea? Bring the outside in. Terrariums can be open or closed (although the open variety are best suited to succulents/desert plants only) and come in many different shapes and sizes.

Most likely, you've seen many pre-built terrariums for sale before, but what's really taken the world by storm is DIY Terrarium Kits. By giving you all the requisite tools and ingredients, these allow you to construct miniature paradises all on your own. There are a wide variety of terrarium kits, including cactus terrarium kits, succulent terrarium kits and terrarium starter kits, so botanical lovers are spoilt for choice.

Are terrariums high maintenance?

The answer to this depends on your definition of the term. If you consider watering your plants and cleaning your glass once a week to be high maintenance, then terrariums might not be for you. However, if you're willing to put in a little bit of effort and care, then a terrarium can be a low-maintenance way to add some greenery to your home.

In fact, if you follow a few simple guidelines, terrariums can be pretty easy to care for. So, if you're looking for a way to add a little bit of life to your home without all the hassle, a terrarium could be the perfect solution. Here's a couple of tips to keep your terrarium thriving:

  • Most plants need at least six hours of sunlight per day, so ensure your terrarium receives enough light. If your terrarium is in a spot that doesn't get much sun, you may want to consider using a grow light.
  • Be careful not to over water your plants. Too much water will cause the roots to rot, and the plant will eventually die. Err on the side of too little water rather than too much.
  • Keep an eye out for pests. If you spy any pesky insects in your terrarium, remove them immediately, as they can destroy the plants.
Glass for aesthetics, plastic for lightness and affordability 

Is glass or plastic better for terrariums?

Glass or plastic? It's a question that's divided the terrarium community for years. Some people swear by glass, while others remain loyal to plastic. So, which is the better option? Well, it all depends on your needs. If you're looking for something affordable and durable, then plastic is the way to go. However, if you want your terrarium to have a sleeker, more natural look, then glass is the better choice. Ultimately, it comes down to personal preference. Whatever you choose, just ensure you keep your terrarium healthy and happy!

How long can a self-sustaining terrarium last?

A terrarium is a self-contained ecosystem, so as long as the conditions are optimal, it can theoretically last indefinitely. Of course, though terrariums have a long lifespan, if not properly attended to things can occasionally go wrong. For example, if the container is not airtight, outside contaminants can enter the system and disrupt the delicate balance. Similarly, if the terrarium is not big enough, the limited resources might eventually become depleted. In practice, most terrariums only last for a few years before they need to be refreshed. But with proper care, a terrarium can be a beautiful and low-maintenance way to enjoy nature for many years.
