Setup
- Prepare Your Workspace: Choose a clean, stable surface away from direct sunlight or drafts. Protect the surface with newspaper or a mat to catch any spills.
- Gather Materials: Ensure you have all kit components, plus a heat-safe container (like a measuring cup or beaker) for boiling water, and hot water (preferably distilled or bottled).
Operating Instructions: Crystal Growth
Follow these steps carefully to grow your crystals. Patience is key for optimal results!

- Prepare the Solution:
- Boil approximately 200ml of distilled or bottled water. Tap water may contain impurities that affect crystal growth.
- Carefully pour the hot water into one of the silicone cups.
- Add one pack of crystal powder to the hot water. Stir continuously with a stir stick until the powder is completely dissolved. This creates a supersaturated solution.
- Allow the solution to cool completely to room temperature. This is crucial for proper crystal formation.
- Add the Seed Rock:
- Once the solution has cooled, gently place one crystal seed rock into the center of the cup. Ensure it is fully submerged.
- If desired, gently wipe the rim of the silicone cup with a clean cloth to prevent crystals from forming on the cup's edge (crystal creep).
- Grow the Crystals:
- Place the cup in a quiet, undisturbed location where it will not be moved or shaken. Avoid areas with temperature fluctuations.
- Observe the crystal growth over the next 7 to 14 days. Do not disturb the cup during this period. The longer the crystals grow undisturbed, the larger and more defined they may become.
- After 7-14 days, carefully pour out the remaining liquid.
- Remove and Rinse:
- Gently remove the grown crystal from the silicone cup.
- Rinse the crystal briefly under cool, running water to remove any excess solution. Pat dry gently with a paper towel.
- Repeat for More Crystals: Repeat steps 1-4 for each additional crystal color you wish to grow.
Displaying Your Crystals
Once your crystals are grown and dry, you can proudly display them on the included LED light-up base.

- Connect Power: Connect the USB-C cable to the LED display base and plug the other end into a compatible USB power source (e.g., computer, wall adapter, power bank).
- Place Crystals: Carefully place your grown crystals into the designated slots on the LED display base.
- Enjoy the Glow: The base will illuminate your crystals, enhancing their beauty, especially in a darkened room.
Maintenance
- Cleaning Crystals: If crystals accumulate dust, gently brush them with a soft, dry brush. Avoid using water or cleaning solutions, as this may dissolve or damage the crystals.
- Cleaning Base: Wipe the LED display base with a soft, dry cloth. Do not immerse the base in water.
- Storage: Store unused crystal powder packs in a cool, dry place. Keep grown crystals away from high humidity or extreme temperatures to preserve their structure.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Crystals are not growing or are very small. | Solution was not fully saturated; solution cooled too quickly; solution was disturbed; tap water used. | Ensure crystal powder is completely dissolved in hot water. Allow solution to cool slowly and undisturbed. Use distilled or bottled water. Ensure the seed rock is fully submerged. |
| Crystals are growing on the sides of the cup. | Solution crept up the sides of the cup. | Gently wipe the rim of the silicone cup after adding the seed rock to prevent crystal creep. |
| Crystals are fragile or break easily. | Crystals were removed too early; improper handling. | Allow crystals to grow for the full recommended period (7-14 days). Handle grown crystals with extreme care. |
| LED base is not lighting up. | USB cable not connected properly; power source issue. | Ensure the USB-C cable is securely connected to both the base and a working USB power source. Try a different USB port or power adapter. |
