Terrariums are the most rewarding way to recreate a slice of nature in your office, your lounge or anywhere in your home. 🏠 🌿
While journeying the early morning dew this weekend I stopped to appreciate the intricate beauty that Mother Nature has to offer. The amount of greenery and bio-diversity you can discover all hidden in plain sight is astonishing.

If you’ve been wanting to journey into having a terrarium or living bowl at home come and talk with our team, we will be more than happy to educate you on how to get started. Stay tuned for our terrarium and aquascaping workshops coming very very soon 😆😁
