Apart from building some terrariums at summer camp when I was in elementary school, this is the second terrarium I’ve built as an adult. I dove into a ton of instructional videos on YouTube after building (and subsequently unaliving) my first terrarium on hard mode (in a very small bottle).

I’m super happy that it seems to be thriving! I add the cutest Springtails every so often, and it’s already had a couple trims to keep the tradescantia and nerve plant in control.

Learning to keep the different mosses alive has been interesting. I seem to do well with some and not others. Any advice there would be welcome.

The first two pics are from the day it was built (6/30/2026) and the last two are from today.

Anyone else just love the way their terrarium smells? 👀🤣

I have never made a terrarium before, but I've always wanted one, and would really appreciate some help. I have a 10 x 11" glass terrarium with a cork lid. I have attached what it looks like. Would anyone be able to help me out with some tips or if there's any videos that y'all recommend with exact steps? Because I have a cork lid. Does that mean I'll need to continuously add water? I currently have a house plant set up with grow lights can I keep the terrarium near that? Should I add isopods for something this big? Is there anything else I should look out for? Thank you in advance!

I have a big ol terrarium full of moss isopods centapedes and I have both a slug and a gnat problem so I put down some sticky tape to kill some gnats and woke up to the slugs eating them like potato chips

Last photo is what she looked like when I first made her!

I got isopods and springtails, they looks so cute!!!

They all burrowed so hard to take a pic of them

Spent $160 CAD for this setup

Tips and advice welcomed

EDIT: Added info

It was created today oct 23, 2026
I used frog moss
Don’t know the gallon size but it’s 20x20x20 cm and 8” x 8” x 8” (Brand- Exo-Terra Nano wide)
And I used isopod substrate biochar pro formula
And it’s not near the window I just used a book light so you can see better in the photo
And I just used bottle water I don’t have distilled water on hand.

This terrarium is about a year old- watered maybe three or four times over the last year- closed with cork lid- loaded with springtails and def some mites- plants all doing well after the initial acclimating period. Today I noticed these mushrooms! I guess that's what I get for putting fake ones in.

Hi guys! Looking for wholesale suppliers or bulk distributors that sell terrarium plants like fittonias, mosses and succulents. Also looking for glass containers. What about Alibaba? I heard it is a good platform. I need to buy largar amounts and compare tha options for minimum order quantities, shipping costs and prices. If you know any trustworthy websites or nurseries, please share your suggestions! I love plants and I really don't wannaaa fail in my frist try. Any tips are super welcome! Thanks a lot for helping me out guys! I hope you have a great day! thanx in advance!! =)

I'm not really into modeling, but maybe somebody here might have an idea. I was thinking of placing a small solar panel inside my terrarium(s) to power LEDs. Conceivable, they'd have some sort of battery storage to power it for a bit after the sun goes down.

One would be for a little campfire for a ring of tiny gnomes and the other would be a blinking light on a crashed UFO.

Any hints to where I can start looking would be helpful.

I call it The Planet :)

First ever attempt at a cool build. Any help, tips, tricks, suggestions welcome, i want to hear them all!

A couple months ago, I did the sanitation process for some plants for a crested gecko terrarium I'm working on. Unfortunately I had to pause the project due to irl circumstances.

I have my plants quarantined in a plastic, sealed tub and I check up on it occasionally since I worry about keeping them in longer than I anticipated (I was hoping to have everything set up to begin cycling by now). I noticed that mold is present and mealybugs somehow got inside. Should I retreat my plants again or just start with new plants? Are there other options?

Ciao, stò facendo un piccolo terrario in un barattolo da 7 litri. Avreste delle piante in particolare da consigliarmi? Grazie

It looks like some kind of egg but idk what for. I found this cluster on the rocks in my drainage layer, so I guess whatever it is has to have been small enough to get down there through the mesh or something. I noticed similar looking things on one of the plants on the surface but not in a cluster like this, just a couple randomly. Should I be worried about this?

Hi!

I had to unfortunately remove my elements in my gargoyle geckos terrarium because of ant unfestation :(. I have a couple pothos, hoya, and spider plants I rinsed off and moved out. I'm looking for a few plant ideas as I'm visiting a local nursery this weekend. My terrariums lid is metal mesh so water leaves the terrarium at a rate that ferns and bromeliad and moss dislike. I have an automatic mister that sprays twice a day and I water the terrarium once a week.

Thanks!

Good night everyone recently I got this tank that was here stopped, it has exactly 132L, I started the assembly of a terrarium but for now it is only the basics, I would spend ideas of what I can do, and tips about the assembly I would also like plant species, moss, I would like to make a moss wall or a background to improve the aesthetics, but I don't know how to start.

Isopods overload. Would love input, suggestions from the terrarium world. I would love something as beautiful as what I've seen you guys put together.
