Growing My Own Crystals 

My partner’s ten-year-old sister got one of these crystal-growing kits last Christmas. Super amazed, I convinced her to let me help her grow the crystals, as the thought of growing crystals was reawakening my inner child! 

We set up the kit, poured some water into some of the powders, and viola, to my surprise, a few days later, crystals had grown! I felt pretty badass growing these crystals, like I was some divine crystal-growing goddess or Mother Gaia herself!

Basics of Growing Crystals at Home 

Before embarking on the task of growing your own crystals at home, it’s crucial to learn about a few general guidelines for safety and set appropriate expectations.

Safety should always come first when cultivating crystals. Although many crystals can be grown using harmless substances, like sugar or salt, others require chemicals that must be handled carefully. 

When handling hot solutions or chemicals, it’s a good idea to wear gloves and eye protection and ensure your working area has sufficient ventilation if working with substances that emit fumes.

Locating the ideal location to grow crystals is essential. Your crystals should have time and space to develop safely without disturbance from pets or children who might try to reach into them. This area should also be cool without direct sunlight.
