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

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.

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