These little crystals hold an amazing amount of water.

Filled the cup to the top and they absorbed that and expanded to fill the whole cup!

This product is a miracle. It is definitely comparable to the MiracleGro water crystals. I bought two of the 3lb bags because it was a better value ($ per #), the seller shipped the two bags together, but still charged double shipping via USPS, but still a better value than ordering than 5# and alot cheaper than MiracleGro. However, I will check into another a brand I ordered previously that was better packaging (this product comes double-bagged in ziplocks), I don't know why I didn't think to check the previous brand ordered for larger packaging and it was free shipping compared to $7.95 S&H for this product. I still give them 5-Stars because the product is a great product and a great value, it really works. I have been using water crystals from MiracleGro (8oz @ $7.95) for years and the results have been wonderful, especially for outdoors, if you live in an area where you get alot of rain and then drought, this product is great or if you have very hard soil where you get alot of run-off when you water your plants, I also use it in my lawn, under my grass I transplanted to keep it from wilting or drying out between waterings. The product will stay in your soil for up to 5 or 7 years. I also used it in my veggie garden with tremendous results, no wilted veggies in the afternoon.

The product aerates your soil when it expands and contracts keeping oxygen flowing through soil, it holds "extra" water that would normally soak on through or run-off as waste, it sticks to the plant roots so roots can absorb moisture from the crystal when soil becomes dry, and it keeps you from overwatering (holds excess water away from roots until they are dry again. For the price/value I use it for lawn, houseplants, veggie garden, flower beds, fruit/citrus trees, etc.

I use these crystals inside fabric neck coolers. Half a teaspoon will absorb over a cup of water and will cool constantly through slow evaporation through the fabric. We've had a heat wave in San Diego the last few weeks and it has saved my life on the tennis courts and out hiking.

The price on these crystals are great! Much less expensive than I have seen anywhere else!

These crystals hold an amazing amount of water and expand more than expected. Before using in soil, tested them to see how much water I could expect them to hold. Placed about a teaspoon, maybe less, in a coffee cup and added a little water. These do expand slightly slowly, not instantly, so it took a few minutes. Checked back and they had absorbed half a cup of water. Added more water. They absorbed that. Filled the cup to the top and they absorbed that and expanded to fill the whole cup! They may have held more than that but I stopped there, with the whole cup filled from one teaspoon of crystal.

This should help the soil in my garden, here in the desert.

If ordering this, don't expect pure white crystals like instant snow. These have a yellowish tinge. Not a problem for mixing with soil but I was a little disappointed. If they were white, I would have been ordering multiple bags to hold for around Christmas. If you want to add coloring to them, that would work!

I purchased the water crystals as a method for water supply for crickets to feed my Fire Belly toads and House Geckos. Water crystals are better than water for this purpose as the insects will not drown and the crystals inhibit bacterial growth and mold unlike standing water.
1 teaspoon of crystals will make 2 quarts of water gel. Mix 1 tsp with 2 qt water, stir and wait about an hour. Any residual water can be removed by pouring water gel into a fine strainer. Water gel can be stored in the refrigerator.

This seller has the best price for water crystals and delivered very quickly. The packaging was only double Zip-loc bags, so you may want to have your own storage when it arrives, I suggest an air tight jar. Make sure whatever you use is 100% dry.

I ordered this product for my reptile feeder insect colonies and it works very well, absorbs water very quickly and filling my jars only takes a small amount. Only negative thing to say was it came in a zip lock bag. After placing my order it was processed and shipped very fast, but with a zip lock I would be worried about it busting during shipment. I'm not sure how to ship it more effectively without a large cost for a more secure way of containment but the product works very well. Would recommend it to other insect breeders.

Product is much cheaper than "brand name" & performs just as well. I use it when setting transplants into raised garden beds, & it really eliminates shock losses. The beds are naturally dry, and the crystals hold water between rains. As I don't till the soil, but add more compost the following year, the crystals remain intact, & help hold water in the bed. A great product, a teaspoon/plant does the job.

These crystals hold a lot of water. I am growing Tropical Fruit trees in Florida as a hobby. I mix these crystals in with the soil when I plant trees in sandy soil to ensure the trees have a water source during droughts. These crystals are a better value than the $8 crystals at WalMart (very small bag).
