Add crystal seeds onto the rock base. Seal lid tightly and allow for 24hrs of optimal crystal growth to begin. Use a flashlight each day to watch growth changes. When crystal clusters reach the water surface, pour out the solution. Crystal growth takes about 10-12 days depending on indoor temperatures.

The crystal can now be kept in a dry place.
