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!

Muy buena actividad en conjunto.
Si nos sorprendió que creciera tanto en una region donde hace frio constante y es muy humedo. Pero se dejó crecer atrás del refrigerador y ahí está el resultado. :D
