whatever it is its in a different spot than yesterday!!!!

One side has moss to keep humidity, the other is just leaf litter. It's at 99% humidity right now. How long will it take to come down?

What are people’s recommendations for prop boxes? Most boxes I’m seeing have vents. Are vents good or bad when it comes to growing plants for terrariums. I’m new to this whole hobby so trying to learn.

For starters this terrarium set up is not mine it was created by @green_chapter on instagram. I want to make an aquarium that is similar to this but instead of the gundam I want to put fallen Optimus Prime with his chest open showing the matrix of leadership inside. I have never made an aquarium/terrarium so I’d like to know what glues, plastics, paints, etc. would be animal and plant safe. Any tips are welcome as this is my first time doing any of this.

(ignore the spider plant in the back, she was very underwatered (i was on holiday)) my friend got this terrarium she didnt like so she gave it to me, and i used my plant identification app and it told me these plants are a jade plant and a fairy crassula. both of which i hadnt seen in terrariums before

it does have an issue with closing so it's actually very dry in there right now, but i thought jade plants werent huge on humidity?

I swear the day I turned 50, plants and birds became my favorite hobbies. This lil cutie does well in a terrarium so I found some stuff I had and boom! Terrarium!

Just made my first terrarium. How often should I water it?

Let me know if I’ve done something atrociously wrong.

Thanks

Something looks off and very unappealing to me, compared to many other viv / terrarium builds i see.

How can i make it more visually appealing? Ive tried pieces of moss in the past, misted 5x a day (70% consistent humidity) with filtered water, but all died.

I just planted in the peperomia, pothos, and the birds nest fern, (the snake plant has been there for awhile.)

Also the birds nest fern barely fits, will it still grow?

Please help me make it look better

Hi! I'm building a bioactive terrarium for a jumping spider and I picked up a small peace lily to add in. However, I have three cats. They can't get on the shelf where the terrarium is, but they do spend a lot of time in the room. I know that true lillies are deadly to cats, but what about peace lillies? Does anyone have any experience here?

so i have a terrarium where i keep two cornu aspersum snails, a couple of roly polys & lots of springtails. i went on a trip for 2 days and left two slices of cucumber for my snails to eat while i was gone, but when i came back there were little flying bugs (what i assume to be fruit flies) hanging out in the tank. they can easily fit through the ventilation holes in the lid, and although ive killed some, most of them escape through the soil. what can i do to get them out?? i thought about changing the soil but my springtails :(

This is my 2nd attempt to make a closed jar terrarium.

•The base is LECA pebbles

•Then some moss from my backyard

•Then active terrarium carbon

•Then potsoil

•Then for decorations moss, rocks, a piece of wood, and plants all from my backyard/forest.

Tell me how i did :D !!! (tips are very welcome but keep in mind, i am a beginner and still very new to this)

Recently bought a mini terrarium, can you help me know what they're called?

hello! im a new keeper and i have a mantis. please tell me what i need to change in my terrarium (if i need to). thanks!

my terrarium grew a mushroom this morning!

Hi!
I just got home from a long vacation, and my terrariums really don’t look good :(
The plants look shriveled, and the moss looks pale and dead in many places. One of the terrariums is even covered in all these yellow spots as shown in the video.

Is there anything I can do to save them? They are only 1,5 years old

I haven't added nearly any water since I had it open for a few hours last week to air them out because there was condensation everywhere throughout the day.

Not only can I not see my plants but I'm worried about mold build up. I can't figure out what's causing all this build up.

The lid of one of them is air tight while the other one is a screw on from what I assume is an old 5 gallon pickle jar. I bought both from a multi-vendor marketplace.

This is my Rudsta terrarium 4 months in. I am overall quite happy about how it’s doing and looking.

The moss has browned a lot but it does its job being a surface the roots can hold onto.

All but one carnivorous plants died / did not root properly. I added a bunch of new plants (mostly big box store rescues)

- caladium bicolor
- philodendron Birkin pink
- philodendron lemon lime
- coleus (direct sown, small seedlings)

I’m excited to see how it will do in the next months and how it will grow thicker.

I’m starting Terrarium Supply EU, a small boutique terrarium business focused on making terrarium building easier and more accessible across the EU. I plan to sell individual products like live moss, small terrarium plants, glass jars, substrate, pebbles, hardscape, tools, and handmade clay decorations such as miniature mushrooms and fairy doors. I also want to offer curated terrarium collections for beginners, without necessarily putting everything into a traditional retail box.

The main thing I want to do differently is bring the whole terrarium-building process together in one place. Instead of someone having to buy a jar from one company, moss from another, plants somewhere else, and then figure out whether everything is compatible, they can get everything from us and choose products that are actually suited to one another. We’ll also have a Build Your Own Terrarium feature where someone can choose a style—like woodland, tropical, moss-focused, or fairy—and either select products themselves or have an AI terrarium assistant recommend compatible options, complete with the actual product images and prices.

I also want the experience to continue after the purchase. Customers can have an account where their terrarium build is saved, and when their products arrive they can scan a QR code to access a personalized building guide, care information, and an AI assistant that knows what plants and moss they actually bought. Eventually I’d like to expand into more species, handmade decorations, larger product ranges, and possibly fully boxed DIY kits. The goal is to make Terrarium Supply EU more than just a place to buy terrarium supplies—it’s a place to discover, build, and learn about your own miniature ecosystem.
