Operating Instructions
Planting Your Garden (Rye Grass)
- Find an area that is easy to clean and waterproof. A kitchen sink with a plug in the drain is recommended.
- Open a small hole in the potting mix, then add half a cup of water. Mix well.
- Place the soil into the deep terrarium sections. Be sure not to overfill.
- Sprinkle your seeds around the soil and then use your finger to gently press the seeds down into the soil.
- Once your seeds are set, fill up the mister bottle with water. Gently spray your seeds to water them.
- Be sure to water your seeds everyday. After 3-5 days the seeds will begin to germinate.
- Once your seeds have germinated, use the rocks to decorate your terrarium. Don't forget to continue to water your plants!

Growing Your Crystals
- Open the crystal growing powder and pour each packet into one cup.
- With the help of an adult, boil some water. Then have the adult carefully pour the water into the cups. Fill each cup with 90ml boiling water.
- Use the mixing spoon to stir each of the mixtures until the powder is completely dissolved. Allow to cool for 5 minutes.
- Once the mixture has cooled to room temperature, add 1 crystal growing rock to each cup. Be sure the rock is able to absorb the color of the liquid to grow its crystals.
- Place the trays in a well-ventilated location where they will not be disturbed for 5-7 days. The trays should be placed out of direct sunlight in a location with stable temperatures.
- After 5-7 days, carefully pour out the extra liquid from the cups. You can remove your crystals by gently removing them from the trays.
- Once dry, carefully remove your crystals from the cups and use a paper towel to remove any excess solution. Place your crystals on the islands of your terrarium!

Maintenance
- Watering: Continue to gently mist the rye grass daily to ensure it remains hydrated and healthy. Avoid overwatering.
- Light: Place the terrarium in a location with indirect sunlight. Direct sunlight can cause the terrarium to overheat and harm the plants.
- Temperature: Maintain a stable room temperature for optimal plant and crystal longevity.
- Cleaning: If needed, gently wipe the inside of the geodome lid with a soft, damp cloth to remove condensation or dust.
