This set is AWESOME! I highly recommend it! I purchased it to grow crystals in the office as a fun experiment to keep me entertained during busy season and it did not disappoint. You need to be sure to follow the instructions carefully. I made a fatal error on my first attempt and did not wait the full 30 minutes before I added the crystal seeding and nothing ended up growing. On the subsequent attempts I followed the instructions to a T and was able to grow beautiful crystals. I even ordered a second set because the results were astounding. The steps are simple enough I was able to grow these in my office with ease. All you need is boiling water and the rest is provided in the kit. The first step is to dissolve the crystal mixture (it looks almost like sugar) into hot water. Next, you have to let it sit for 15 minutes, and then transfer it into a clear plastic container where the crystal will grow. WAIT ANOTHER 30 MINUTES after the water is transferred. This step is crucial otherwise the crystals will not grow. Once you have waited the allotted time you drop in the crystal seeds. They provide blue, red, and white crystals so you can mix and match them to create different colored crystals. It seems that each type of crystal seed grows a different shape of crystal. I noticed that the red crystal seeds will grow more block-like crystals whereas the blue seeds will create more sharp/pointy crystals that flower out. Blue and red will create a crystal that looks like a combination between the two - it flowers out but is more block-like. Keep this in mind when you choose the colors you make. You will start seeing growth overnight. Its amazing to watch the progress. On the instructions it says it takes 4-7 days before the crystals are fully grown. I would keep an eye on them and drain the water when the crystal is about to emerge from the water. If you leave it too long the crystal is exposed to the air it will form "snow-like" growths on the top (which I think are ugly). The rate of growth will be affected by the temperature of the room as well as the size of the crystal you are growing. The crystals grow well in warmer temperatures. The small crystals will finish growing faster than the large ones. Each bag of crystal mixture can either make 1 large one, 2 medium sized one, or 4 small ones. The kit allows you to grow 1 large crystal, 2 medium crystals, and 4 small crystals simultaneously because that is the amount of containers they provide. If you want to grow 3 large ones you can grow them one at a time because they only provide one large container. I think the large crystals are the coolest.All in all this is an amazing kit. Everyone in the office is jealous and now they want to grow their own crystals too. 5 stars!!! I want to make ALL the crystals! ... show more

    • Fantastic value with great expirimentation oportunity
Style: 7 Crystals
Great value- I'm looking forward to practicing with this kit before moving onto more expensive growing sets with my niece and nephew. Pros: Great value. This kit has a great focus on experimentation where other kits are more focused on the growing aspect. This kit has several different sizes so you can try growing the small ones in different locations to see which one is the best to grow the larger ones in. You can also experiment with the color of the crystals. Do you want a deep blue, light blue, red, purple, pink, etc? Mix the seed mixture in different amounts and see what you get as a result! If you're the impatient type, you can also use the supplied materials to mix up all three batches in one day. Cons: When compared to other kits like the one from National Geographic, this one just gives an impression of being very budget minded or cheap. Granted, it does cost less than half the price, but it's the minor things that add value. For example, there aren't any dedicated growing containers. Instead you are forced to reuse the plastic display containers that are made out of very thin plastic. Every time I touch them, I am terrified I'll damage it. The last thing I want in my display case is a scratch from the crystal that grew in it while attempting to remove said crystal. The Mixing container for the National Geographic case also had a fill line in the event that you don't have a measuring container. The fill line is clearly absent in this kit. Neither of these things are a deal breaker, this is still a fantastic introductory kit. For my money though, if i had to buy another kit i would more than likely go with the one from National Geographic again. ... show more
