r/terrariums

I swear I didn’t plant this.
A few weeks after building my rainforest tank, this tiny white “spirit-like” organism suddenly appeared out of nowhere.
It looks almost unreal — like something from another planet. 🌿🤍
That’s the part I love most about closed ecosystems:
if the environment is healthy enough, life starts creating itself.
Tiny forests. Tiny climates. Tiny miracles.
Anyone know exactly what this little guy is?

It’s coming home after work and zoning out in front of a rainforest you built with your own hands. 🌧️

Hi everyone! I’ve had this nerve plant for ~4 years now. It fit in my palm when I got it and I’ve grown it thru multiple terrariums into its final resting place - this huge Walmart terrarium that it will never be able to move out of bc I’d have to smash the whole thing to get it out lol. I watered it plenty thru its growing stages but since planting it in this terrarium and putting the cork on the humidity and sunlight have done the rest of the work to keep it the appropriate climate in there.

It was originally super full at the bottom but I had to move into an apartment for the past two years that it never got enough light in, hence it dropping its bottom leaves. A couple of months ago I moved into a new place with the perfect lighting again and it has since completely regrown at the top and seems to be flourishing again!

I was wondering if there’s anything I could do to help with the bare bottom of the plant, or if that’s just going to be barren from now on because of the time spent in the dark? I can tell there has been a little regrowth down there but I’d love to get it back to its bushy, full self if possible!! Should I just leave it or is there something I can do to bring back the bottom growth?

It's on a 4lt jar that I didn't want to photograph from the outside because the condensation makes the photos look horribly bad and I just take em with my phone. I'm really happy to see how many new sprouts appeared and to know that it's still going on (I know 11 days is not that much at all but STILL I'm proud lol). Something that concerns me a lil but is the white funghi or whatever it is that's growing on the piece of bark (bark? idk, english isn't my native language, I'm sorry 🫠) between the plants and the pieces of wood on the border/edge/youknow, mostly because I don't think there are enough springtails (yet) to get rid of it and I'm kinda worried that it could damage the plants.

Below everything that's visible I put a layer of rocks anddd that's all about it! I hope I can receive useful tips if someone wants to leave them and I am really happy and excited to read opinions (and critics of course)!

The left one is about two weeks old and the right is a week. I saw some YouTube shorts and my husband already grows carnivorous plants and tillandsias and such so I didn't have to buy much in the way of supplies. I think I'm hooked.

Hello! Which of these plants are good for terrariums?

I built a terrarium a little over a year ago and it’s not doing well. Many of my plants died and I think it’s probably because I didn’t set it up right from the beginning. The first things to go were the plants on the cork. Then, the two terrestrial orchids so probably not as he right substrate either.
I had a fogger that I placed in a plastic cup behind the cork but I would have to be constantly refilling the water everyday because it ran out after an hour.
Also the moss I used was foraged from around my house and maybe being in a tropical terrarium was not their favorite, also I thought they would spread but they never did anything.

I’m looking for something more self sufficient now so a better system for creating a fog (I’m not planning to add anything other than plants and springtails) and air circulation. Some of the orchids that I had preferred to be cooler at night and warmer during the day. I’m curious how people could achieve something like this?
Also, what is the best system for creating high humidity/fog that doesn’t break the he bank? Like, I prefer not spending $200 in a fogger
And how do I get this look with moss? What type of moss is it? And where can I buy this species?

Recommendations for fogger that it’s not too expensive

It’s our first terrarium in a small jar. We made these at one-day class so the materials we used were sourced properly. We left the lid softly opened for it to breath the first few months, but we closed it completely when we were gone for a trip.

Also Should I be concerned by how many of them there are?
We stopped watering them a couple months ago and the soil seems to be moust still. How often should we have to water them?

Who else finds building pieces so relaxing and centering? Made with intention, it’s like part of you becomes embedded with the terrarium.
The glasswork was on the clearance rack. All the moss harvested myself. All plants are from my propagation boxes.

does anyone know if this kit for a crested gecko is worth it or should i just buy stuff individually?

If I got more plants etc, I know it's not tall, but would it work for crested geckos? It's about 23-24C steady and around 60-70° with occasional misting. Right now it's home to one living vampire crab, the rest have died out.
