The problem statement for growing a charcoal crystal garden would be: How can charcoal be combined with a crystal-growing solution to create visually appealing crystal formations on the charcoal surface in a controlled and replicable manner?
To grow selenium crystals with bluing charcoal and ammonia, start by dissolving selenium powder in boiling ammonia. Add bluing charcoal to the solution to act as a reducing agent and promote crystal formation. Allow the solution to cool slowly to encourage crystal growth, and then filter and dry the crystals for collection.
they grow faster on charcoal
Crystal's grow by a process called nucleation.
Dissolve Copper sulphate in water. Keep adding it until the solution is saturated (no more dissolves). Decant the clear, saturated solution into a clean beaker. Now tie a thread around a small copper suphate crystal. Wrap the thread around a lolly stick. Dangle the crystal in the saturated solution and leave it all on a window ledge. As the water slowly evaporates, copper sulphate solid will be deposited on the best surface it can find. This will be the dangling crystal, and it will grow.

NO
there are materials inside of the crystal to help them grow
Blue whales grow and grow but when I was told everyday.
A small quartz crystal can grow about 1mm a week assuming it is in a stable matrix.
