Guides Included
Scan the QR code printed inside the box flaps for your Step-by-Step Build Guide and Care Instructions, so you can set up and maintain your terrarium with confidence.
Difficulty & Care
Build time around 30–45 minutes. Once planted and settled, a closed terrarium is wonderfully low-maintenance — it recycles its own moisture, so watering is typically needed only a couple of times a year. Keep it in bright, indirect light, away from direct sun.
Sustainability Tip
Please consider reusing the cardboard box for storage or repurposing — every small step helps support a greener planet!
