Additional terrarium tips:

There will be a lot of reptile keepers that suggest a specific model of spray foam or silicone glue, but in reality most of them may work properly—just make sure they do not have any mold inhibitors and that the spray foam is fully sealed by the silicone.

The most recommendable real plants, in my opinion, to place in your bioactive terrarium would be the following:

Pothos Plants

Often called the “armored plant”—are highly resilient, fast-growing, and thrive in a wide range of terrarium conditions.

Brazilwood (Palo de Brasil)

Grows steadily, provides sturdy vertical surfaces perfect for wall-climbing geckos, and adapts well to terrarium conditions.

Waterfall!

Let´s work with remains!

A cleaner approach:

When working with spray foam backgrounds, cover about half of a plastic pot with foam and let it fully cure. Add silicone and press in substrate for a natural look. Cut a small drainage hole at the bottom of the pot.

Glue it securely onto the terrarium background or side, fill it with soil, and add your plant. Water it regularly, and it will thrive in its elevated space.
