This is my first air sealed terrarium that I sealed 5 days ago.

The plants were thriving until I spotted these small white gelly type of worms they don't move or twitch they're just being there.

I made this terrarium with leca pebbles for the base, active carbon and pot soil that I bought. For decoration moss and rocks I found in my local forest and plants that I bought.

If you know what it is please let me know!!!

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.

Hello guys I just made my first terrarium, what do you think about it ?
Any advices ?
Thanks :)

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.

It took around four months from seed to bloom for this micro Sinningia species.

I am a newbie when it comes to culturing fruit flies i have no idea where to look or who to ask so if anyone could point me in the right direction thank you!

I made a homemade fruit fly media mix

Using ingredients :

Water
Vinegar
Instant mashed potatoes
Powdered sugar
And nutritional yeast

And place it inside this container with my baby fruit flies from the store bought container.

To my surprise not much long later there is black and green mold-like growth atop of the mix! Curious as to whether this is a normal part of the process or bad and what i can do to change it. My flightless fruit flies ended up laying eggs in here which is exactly what i wanted, there are larvae crawling around and the population has noticeably increased.

Are these safe to feed my toads?

It has a couple types of moss. Some growing on oak bark, on a stick, some hydrocotyle cuttings from my fish tank, moss rose, and like 3 more random plants i found growing in a gutter

The chip was there before the crack, I put the rocks and i noticed the rocks were still wet and since i wanted it to dry; i blow dried it for 3 mins before realizing the crack. I am so stupid.

Hey for some context in January there was a terrarium sale at my local garden and i decided to purchase one. About a month or too i noticed there was a small snail inside. I did research and i think it’s a glass onion snail. We put in lettuce daily and he ate it. At the start of June we saw 2 snails in there and we continued feeding like normal. Today i check in on them and noticed that there was a ton of snail babies on the lettuce. Its a small terrarium and I don’t know what to do or what they are.

I made this for the 2 ladies at the hospital who have been doing my iron infusions. After commenting on their pretty Shivereana Ficus, said they “want” to be plant ladies, but struggle with keeping them alive 😅 I figured a terrarium would solve the problem. Everything except the medium came from my yard.

Hello! I am an avid indoor gardener with a decent collection of houseplants. I am also an avid outdoor collector and scavenger. I have a elk jaw specimen that was burned in a wildfire. I would like to add it to my new build terrarium as a focal piece. It was found deep in the woods and has been outside in my garden since then. Planning on scrubbing it with water before I add it.

Is this a bad idea for any reason? Do I need to do any additional prep?

Thanks for any insight provided!

I was thinking of buying something from here but I'm not sure if it's legitimate or not.

I’m like halfway through my build, but I don’t know any finishing touches would be appreciated to fill these cracks in. I tried working with Aqueon silicone and it was a horrible mess… both times I’ve tried working with it. It was a nightmare..

I see so many beautiful looking walls with moss and plants and I’m trying to do the same thing
