Terrarium setup

Build the right terrarium base layer

Closed terrariums need a stable base that balances moisture, structure and hygiene before the planting layer goes in.

Frequently Asked Questions About Terrarium Kits

What makes a good terrarium kit?

A good terrarium kit starts with a suitable container, clean substrate, and plants that genuinely want the same conditions. Decorative extras matter far less than getting the plant mix and moisture balance right.

Should I choose an open or closed terrarium?

Choose by plant type, not just by looks. Closed terrariums suit small humidity-loving plants, while open terrariums stay drier and work better for plants that dislike trapped moisture.

Can I put succulents or cacti in a closed terrarium?

Usually no. Most succulents and cacti struggle in trapped humidity and weak airflow, so they are better kept in open setups with a faster dry-down.

Do terrariums need fertilizer?

Not at the start, and usually not often. Terrariums are easier to manage when growth stays steady rather than fast, so feeding too early often leads to algae, mould, or soft overgrown plants.

Why is my terrarium foggy, mouldy, or starting to rot?

That usually means it is too wet, too stale, or planted with the wrong mix of species. A little light condensation can be normal, but constant heavy fog, mould, and soft collapsing growth mean the setup needs to dry out and rebalance.

Die Pflanzen waren prima verpackt und ein heatpack war im Paket enthalten. Die Lieferzeit hat 2 bis 3 Tagen gedauert, was aus meiner Sicht wirklich gut ist. Alle drei Pflanzen haben die Lieferung gut überstanden. Ich habe mich auf Hoyas spezialisiert und habe schon die nächsten Pflanzen meiner Wunschliste auf der Website gefunden. Daher wird die nächste Bestellung nicht lange auf sich warten lassen.

The plants are carefully packaged and arrive in great conditions (I’m based in Spain) and they’re always there to help in any way they can with your purchase.I have and will always recommend Foliage Factory to every friend I can. I’m not only satisfied with their plants and prices, but their customer service is exceptional.

José

★★★★☆

Very healthy and well packed plant. Unfortunately there was one plant that ordered couldn’t be delivered as it was out of stock hence 1 star less.

Sam

★★★★☆

Die Sendung kam leider in keinem guten Zustand bei mir an, kann passieren. Habe mich darauf hin sofort an Foliage Factory gewandt und habe selten einen so guten, schnellen, freundlichen und kulanten Kundendienst erlebt.

Frauke

★★★★★

Everything arrived in good condition and very well packed - it wasn't easy with a fragile plant and a heavy bag of substrate. I recommend it!

Lia

Bester online-Pflanzenhandel den ich kenne (habe davor 4 andere ausprobiert). Eine teure Pflanze wurde beim Transport beschädigt und mir ersetzt. Der Kontakt dabei war auch sehr nett (danke Jan) und hat mir gut geholfen. Die anderen Pflanzen sind in einem sehr guten Zustand, keine Schädlinge, super Bewurzelung. Nur zu empfehlen! :)

The plants have arrived in perfect condition, the roots and the foliage so so healthy! I had problem with 1 plant out of 16 and they have responded to my email almost instantly and the issue was resolved straight away. I'm really impressed and satisfied, definitely getting more plants from them again!

Patricija

★★★★★

I received perfectly heathy and absolutely beautiful plants, even bigger than expected. The delivery within Europe was really fast. I think Foliage Factory has one of the best plant web shops in the internet. It‘s just great to get so much informations about the plants. I will definitely order again :)
