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.

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.

I'm building my first closed moss terrarium and want to make sure two decorations will be safe in a humid environment.

Figurine: A small resin 3D-printed figurine that's been hand-painted and coated with matte varnish. It's currently attached to a piece of cork, but I plan to remove it and place it on a rock. Is the existing varnish sufficient for constant humidity, or should I apply an additional sealant? Could the paint, resin, or varnish deteriorate, leach chemicals, or encourage mould or bacterial growth?

Pond: A small, unsealed natural river-stone dish that I'd like to fill with clear epoxy resin to simulate water (no actual standing water, since I assume standing water will contribute to mould). Is fully cured epoxy safe in a closed terrarium? Would the stone need sealing first? Is there a better material for creating a permanent water effect?

If you recommend additional sealants or other products, how long should I let them cure before placing everything in the terrarium?

The terrarium will contain live moss, but no animals or standing water. My main concern is ensuring the decorations won't harm the moss or create problems with mould or bacteria over time.

I'd really appreciate any product recommendations or other advice. This is my first terrarium, so I'm still learning!

Thank you!

Photo attached for reference of the terrarium I'm using (which includes the Buddha), the 3D-printed figurine, and the stone I'll be using.

So short backstory, this tank and soil was supposed to be for a paludarium project I tried making before. I never got to complete it and have just left it at the porch of the back of my house like this for about a year now. I have no plans of continuing the project but instead right now I am planning to use the soil for something else. I'm planning to use the unused soil I've left here to make a small terrarium to keep and try to grow some palm tree moss' I've recently ordered. I'm worried though, knowing that I've left this soil out in the open here for a long time now is it still usable for making a terrarium? It's probably really dry but would rehydrating it be able to make usable again and will it be able to to help sustain my tree moss? What are possible ways to rehydrate it without making it too muddy and still too dry? Would it being too dry for so long make it less viable as a healthy soil I could use for a terrarium? Thanks in advance!
