Looking for a DIY Closed Terrarium Kit? Here Are the 7 Best!

Terrarium kits are made to make your life easy and save you money.

Everything is found in one place; there’s no need to buy more than you need, and absolutely no paying for separate postage. Sounds perfect to me!

I’ve hand-selected four great closed terrarium kits for you. The best all-rounder, the best mossarium kit, and the two best kids kits – each selected based on the quality of materials and appropriate plant and moss choices.

Honestly, I’m very critical of terrarium products, and I was really impressed by these kits. Many of them have exclusively 5-star reviews and, importantly, pass my rigorous judgment. 

So, let’s take a look at what we’re working with.

7 Best Closed DIY Terrarium Kits

1 | All-Round Best Terrarium Kit

This complete kit by BTV Terrarium Kits is genuinely the best kit I’ve come across online.

And it’s perfect for someone wanting to jump straight into building a more significant piece.

It comes in several container sizes, and you even have the option to grab the kit without the glassware (or the plants) if you already have some options to hand. So it’s great for adapting to your needs.

The plants are appropriate for a closed environment, and the substrate and drainage material look very high quality. The only thing it doesn’t include is a spray bottle, which you can pick up cheaply from Amazon.

Overall, a fantastic terrarium kit for adults!

2 | Best Terrarium Kit for Gifting

This lovely kit by Kraft Stories is a fantastic gift for a special someone because it comes in a beautifully designed package.

And (at the time of writing this), it boasts exclusively 5-star reviews. Nice!

With a single type of moss, it’s a neat and tidy beginner’s terrarium build and the perfect way to dip your toes in the hobby.

Just note that the moss is live, so remember you’ll need to care for it until it’s time to gift/use or consider not ordering it until you’re ready.

3 | Best Terrarium Kit for Beginners

This playful by MyDIYTerrarium is ideal for beginners; it’s a straightforward build and a nice starter size.

There are a few different cute style options, too. You can choose between blue sand and shells, resin ladybirds, or little rubber ducky figurines.

The glassware even has an inbuilt LED light, so you can keep your terrarium in a darker area where plants typically need grow lights.

4 | Best Mini/ Mossarium Kit

This gorgeous moss terrarium kit by EK Terrariums is about as cute as it gets – measuring up to only 3.4 inches tall.

If you want an inexpensive, simple, and classic terrarium starter kit with quality materials, this adorable moss project is the one for you. And it’ll only look more lush and wild as it grows over time.

Why not try adding a cutting to spice it up a little more? Something like Ficus pumila or Peperomia prostrata (String of Turtles) would work a treat and look great. 

Check out our DIY Moss Terrarium Guide for more help and inspiration with these mossy wonders! Or peruse our picks of moss terrarium kits for different projects.

Alternatively, EK Terrariums also has plenty of ready-made mossariums if you fancy skipping the DIY element altogether.

5 | Best “Landscape Style” Terrarium Kit

This cute kit by Green Mountain Moss it’s perfect for someone with an eye for design.

While it’s a simple build in terms of container size and plants, what’s extra special about this kit is that it puts hardscape at the front and center.

Hardscape (rocks and wood) helps set the scene and create scale in the terrarium world, and the result it creates is a stunning natural look.

So, no matter how small your piece may be, you can rest assured that when built, it will look professional and sleek.

6 | Best Terrarium Kit for Kids

This great kids’ kit by Sugar Blush Studio not only offers up an opportunity to teach the water cycle but the seed cycle too.

How come? This one-of-a-kind kit involves chia seeds, which will sprout just a few days after planting.

As I’ve mentioned, kids’ kits often can put style over substance, and that certainly isn’t true with this kit.

Not only does it include all the necessities (drainage stones, charcoal, soil pellets, moss, seeds, tools), but it also has all kinds of extra stuff that kids love. 

A personalized stand? Yes. Miniature dragon? Yes. Plastic gemstones? Yes. Optional glass jar with a solar-powered lid that charges in the sun and lights up in the dark? You know what…Yes.

7 | Best UK Terrarium Kit

This awesome kit by Ome is perfect for anyone UK-based.

With all the materials you need and the option to go with or without tweezers and mister – in case you already have those knocking about – you can be sure to only pay for what you need.

It comes in two sizes; classic (3 plants), and XL (5 plants) for those wanting to build a showstopper of a piece straight away.

They also plant a tree for every order so you can feel good about your purchase.

Terrarium Kit Red Flags

Of course, there are more kits out there than I’ve found for this list today.

So, if you decide to expand your search, let me give you four tips.

1. If you see any closed terrarium kits that include succulents or cacti, run away and never look back. Arid plants won’t survive in a closed, humid environment; they’re a logistical no-no and will need an open terrarium to thrive.

2. Live moss in an open container is also a crime against horticulture; it will dry out and perish quickly (BIG nope)…

3. Keep an eye out for any terrarium kits with Venus Flytraps. They’re possible to create (sort of), but certainly not for the faint-hearted terrarium builder. They’ll need very particular care requirements and an open container. There are much more suitable carnivorous plants for closed terrariums, but if you want to attempt it, see our Venus Flytrap terrarium guide.

4. Another thing to watch out for is kits that include foraged items. Unsustainably taking things from natural environments for free and selling them online for a profit is a great money-making idea but not an ethical industry to support.

Appropriate Closed Terrarium Plants

We’ve covered what won’t work, so what kind of terrarium plants should you be looking for in a closed terrarium kit?

This is by no means an exhaustive list, but there are some good things to look out for:

  • Peperomia
  • Pilea
  • Ferns (especially miniature varieties)
  • Fittonia and Polka Dot Plants
  • Syngonium 
  • Tradescantia 
  • Calathea, Jewel Orchids, and Air Plants are compatible but enjoy airflow now and again.

And we’re only just scratching the surface; there’s so much more. Check out our closed terrarium plants guide for more.
