### ⭐⭐⭐⭐⭐ My guide
*by T***T on July 9, 2025*

Follow my guide1. Follow their traditional instructions2. Once u have a good grow with crystals covering the whole stone and it's not falling apart remove it3. Chip off undesired edges of growth4 save all the current water salt solution and chip off any dried salt/crystals from the edges of cup or bowl and take a small pan pour all that into pot and heat it and stir till all is liquid and pour that back in the cup or container you were using to grow but do not put the stone with the leftover grown crystals in until it's warm (WARM)5. Repeat this process till it looks like mineAfter this kit I just ordered alum from Amazon and started growing my own crystals with out needing a kit anymore .
