Grow Better Crystals with Deionised Water: Here’s Why It Matters

Crystal growing kits are a fun, hands-on way to get kids interested in science — but did you know that the type of water you use can affect how well your crystals form?

If you’re using a kit like the National Geographic Crystal Growing Lab, using tap water could hold you back. Here's why HYDROFYX Deionised Water from The Somerset Clear Water Company is the best choice for growing crystals at home.

🔬 Why Does Water Type Matter in Crystal Growing?

Crystal formation is a delicate chemical process. Tap water contains:

• Minerals like calcium and magnesium

• Chlorine and trace metals

• Impurities that slow crystal growth or cause cloudy formations

These impurities interfere with the crystallisation process and can result in dull, discoloured, or uneven crystals.

✅ Deionised water, on the other hand, is completely free from those impurities — giving your crystals the best chance to grow larger, clearer, and faster.

🌈 Perfect for STEM Kits Like:

• 🧪 National Geographic Crystal Growing Lab (Amazon UK)

• 🧬 National Geographic Mega Crystal Growing Kit (Amazon UK)

• 💎 National Geographic Crystal Garden Kit (Amazon UK)

If the instructions mention “distilled” or “purified” water, deionised water like HYDROFYX is not only suitable — it’s often better.

💧 Use HYDROFYX Deionised Water for:

• Vibrant colours

• Sharp edges

• Faster growth
