Fun crystals to grow, I let them grow for about 2 weeks and they turned out really well. The only issue I had was removing them from the seed rock, I completely destroyed a crystal trying to remove it and didn't bother with the other crystals. The light up display is a cool idea and based on other reviews they turned out great, I just had troubles removing the crystals without destroying them. Photos were taken with a DSLR and a macro lens.

This product is fantastic for hands on fun and it turns out to really cool thing to have around when complete.

I really thought this was pretty cool! My 6 yr old did also, but I did most of the work. I grew three at a time in pint glasses and let them grow on a shelf in my son’s walk-in closet (where I knew the cats couldnt get at them). Overall, super neat. I let them grow the full 7-day period. So, be patient! Definitely get out all the supplies you will need before conducting all the steps. I highly recommend setting up the area beforehand, too.

I didn't have high hopes on how this would turn out but my daughter wanted this kit for Christmas so I decided to give it a try! And wow! Instructions say at least 3 days and for best results 7 days. We set these aside in glass cups and forgot about them for a week and a half but the results were very surprising!TIP: Getting them out of glass cups was a little tricky but we poured hot water in the glass and swirled it around very briefly and tipped it out. The crystals slid out with a few taps.

The media could not be loaded. So I need to revise my review. At first I was very pleased with this “Mega crystal growing lab” until we bought another National Geographic crystal growing lab. The new kit only has 3 crystals to grow in it and a sleaker lighted base but what bothered me was the differences in the instruction book and the difference in the seed rock. In the kit that I am reviewing the instructions say after boiling a cup of water to pour a small amount of the crystal growing powder into the hot water and stir it with the starring stick until it dissolves, then pour in a little more powder and keep stirring, continue pouring and stirring until no more powder will dissolve into the solution. This process should take no more than five minutes Then it says to carefully pour the crystal growing solution into your crystal growing chamber, then let the solution cool for 15 minutes and then place in the seed rock and to leave the experiment undisturbed for 7 to 10 days while the Crystal grows. We followed these instructions to a T. Now the new set with only three crystals in it, the instructions say to pour ALL of your crystal growing powder into the growing chamber and then pour the cup of boiling water into the crystal growing chamber and to stir for two minutes until it is fully dissolved then let cool for 10 minutes And carefully place the seed rock into the solution and it says to let it sit for 3 to 4 days but for best results, let it grow for seven days. We did this two days ago. It hasn’t even been a full 48 hours and the crystals are already bigger in two days than the ones we made from this kit following this kit instructions that we let sit for a week and a half. We only made four crystals out of this set that I’m reviewing but two of those four we could not pull the seed rock away from the crystal for the light of the base to shine up through the crystal so I’m having to take a Dremel tool and try to drill it out so the light will shine through it. As I said earlier, the seed rocks from this other national geographic set were different. They were kind of smooth, so I’m thinking that they’ll pop out easier but the two that I was able to remove from this set one of them removed fine but the second one the crystal actually broke while removing it and then like I said two more I couldn’t even get to remove so I will post pictures of what I have right now and then in a few days once these other crystals are finished growing. I will update my review again to let you know if those seed rocks came out easier, and I will also share pictures of both instruction guides, but if you are going to buy this kit, I suggest going by the instructions that say to dump all of the Crystal powder in at once because doing it a little bit at a time in a little bit at a time the water cools off and you can’t dissolve as much Crystal powder so your crystals don’t grow as big. I still think it’s a great experiment to do with your kids. I just wish that the instructions were the same as in the other set so we would’ve got a better result. Also I wanted to add that it truly is just the difference in the instructions that made the difference because the red crystal and the glow in the dark crystal that we are growing now came out of the mega crystal growing lab set. Only the crystal powder for the blue crystal came from the new set. So use the instructions pictured here that say use all the crystal powder!My 5 year old son and I had so much fun making these crystals. It’s a good value and easy to use and clean up was a breeze. The hardest part was finding a place in my home to set it where it would be undisturbed while the crystal grew. But when it was finished we had big beautiful crystals! I love the lighted stand to display your crystals on but you have to be super careful removing the crystal from the silicone growing container or you will break shards off of your crystals. Totally worth the money! We still have a few more to grow. I personally can’t wait to do the glow in the dark one!
