Since the dawn of terrariums, thrifty hobbyists have faced one recurring problem time and time again.
It’s hard to find lids to fit pre-existing containers, and it’s hard to find containers that come with lids in the first place.
Closed terrariums are obviously more fun than open terrariums, so there must be a way (there, I said it, sue me).
I’ve found, tried, and tested the best terrarium lid solutions, and today I’ll share them with you.
So let’s jump to it!

Custom Terrarium Lids (For Lidless Containers)
Picture it. You’re in Ikea, you’ve worked your way through the labyrinth, the Swedish meatballs are in sight, and only one last obstacle remains – the bargain bin.
That’s when you see her: glass, gigantic, and only $10.
She was born to be a terrarium.
But there’s a catch, as there so often is with thrifty glassware finds. Your new favorite terrarium container is lidless.
Fear not; you have options. Here are the three best ways to approach it:
1 | Acrylic/Plexiglass
All hail the best all-rounder and my personal go-to solution for lidless terrarium containers.
It’s transparent, easy to clean, and readily available.
- If your container has a circular opening, you can grab one to size from this shop on Etsy.
- If your container has a rectangular or square opening, you might need to do a little more digging to find the exact size, but there are plenty of vendors to check out on Etsy.
2 | Cork Plug
A big cork stopper is fabulous if you want more of a rustic look and have a container with a circular opening.
And, because they’re wider at the top and narrower at the bottom, cork stoppers are suitable for a small range of opening sizes, just like a door wedge. With other lid shapes, you need to be much more specific.
Just be aware that it will block light from the top, so you might need to pop your piece closer to the light source or next to a grow light.
Or, take a look at some of our low-light terrarium plant picks for options that are better suited to the project.
3 | Saran Wrap
Don’t sleep on saran wrap.
It’s not perfect, but it’s the ultimate “it’ll do for now option.”
And despite what you’d think, if you’re careful to stretch it flat and trim around the edges, it can look relatively neat. Relatively.
The main thing I noticed is that it can get super dusty, and if you need to take it off for any reason, it’ll most likely tear, and you’ll need a new piece and proper reapplication each time.
Make Your Own DIY Terrarium Lid?
For the absolute DIY heroes out there, I’m sure you’ve already clocked that making an acrylic lid is pretty straightforward.
And it is, provided you have the right equipment.
Acrylic is cheap and easy to work with, but buying a vice and a saw is so much more expensive than I had anticipated (well over $100), so it’s only viable if you already own them.
Lids for Bioactive Terrariums & Animal Vivariums – Things to Consider
If your terrarium is home to any lively inhabitants, this whole thing will need a different approach.
Here’s what you need to consider:
- Animals need ventilation and airflow (duh).
- You don’t want any escapees running around your house.
- Depending on the animal and setup, you’ll need easy access for cleaning and feeding.
To make your life easier, the acrylic custom lid vendor I mentioned earlier has an option to add holes in for $1.
Of course, this solution is only suitable for species large enough not to slip through the holes and small enough not to be able to budge the lid.
If your residents are on the smaller side (I’m looking at you, springtails and isopods), you might also need to add a fine mesh to the lid.
Larger animals will naturally need a larger tank-style container to suit their spatial needs.
So for a lid, you’ll likely need something heavier or physically attached to the container.
There are plenty of ready-made vivarium tank lids available to purchase. And some good options if you want something a bit more high-tech, like a sliding lid.

Buy a Terrarium with a Lid
1 | Cloche Dome
This cloche by NCYP Garden on Etsy is stunning. It’s dainty, it’s timeless, and it’s surprisingly inexpensive at less than $20!
What better way to have a lid than to enclose the entire piece with it?
2 | Hinged Wardian Case
Wardian cases are modern glass pieces inspired by the historical roots of the terrarium. And they make a statement.
This glassware piece by H Potter on Etsy is a beautiful combination of traditional and relevant styles.
Admittedly it’s more pricey than the other options, but for that kind of craftsmanship, it’s pretty reasonable.
3 | Wooden Ball Lid
This piece by CYS EXCEL on Amazon is so interesting. It uses a wooden sphere to seal the opening, and for under $35, it’s a steal.
The only downside is that more narrow openings are more difficult to plant in, but if you’re up for a challenge, glassware doesn’t get chicer than this.
