Remove the petri dish of moss from the top of the box and place out of direct sunlight.
Empty the stones from cloth bag into a strainer. Run stones under water for 30 seconds to rinse off any dust. Then, pour clean stones into a cup and leave them to soak in water for at least 30 minutes or overnight.
Open the petri dish containing the moss. Using a fork, gently lift the moss off of the nutrient gel-coated disc. Submerge the moss in a dish containing a half-inch of water. Save petri dish for next step.
Retrieve the cup with the stones and pour out the water. Using a teaspoon, scrape the gel out of the petri dish and add it to the cup with the stones. Add a teaspoon of fresh water to the cup and mix with teaspoon.
Carefully spoon stone-gel mixture into the base of the glass terrarium. Take care to avoid touching the sides of the terrarium with the gel. When the mixture has been fully transferred, use the base of the spoon to flatten the stones across the bottom of the terrarium.
Retrieve dish with moss and remove plastic backing to the moss, using a fork to get under the moss if required. Using your fingers, roll the moss into a cylinder that can fit through the terrarium opening. Place the moss inside the terrarium on the stone-gel mixture. Position the moss with your fingers or a fork. Once you are satisfied with the position of the moss, gently press it down, taking care to not squeeze the gel out of the sides of the moss.
1. Indirect Light
Orbella doesn't respond well to hot, dry climates and prefers temperatures below 77°F (25°C). Place Orbella in a room with a window where it will receive natural light or where the lights are on at least eight hours a day. Avoid intense, direct sunlight.
Water Orbella twice a week. Keep the gel under the stones hydrated by pouring a quarter of a cup of water into the terrarium, or enough to ensure the moss is submerged. Fully soak the moss for 2-5 minutes. Then, pour away excess water. You may also add home plant fertilizers to the terrarium if you wish.
Orbella may require less watering in a humid environment (such as a bathroom) or may require more watering in a dry climate. If Orbella shows signs of curling or is not moist to the touch, it requires additional water.
If you are away for 3 or more days, water the moss before your departure as detailed above. Cover the terrarium opening with plastic wrap to retain moisture.
5. Forgetting Water
Orbella may be recovered if its watering schedule has been broken, but not if it appears decomposed. During recovery, Orbella’s fragrance may take time to fully return. To revive dry moss, soak it in water. Set aside for 30 minutes before pouring out excess water. Take extra care in pouring out excess water as the stones can become loose when Orbella dries out.
