Customer Questions & Answers

my planters are 4x4x2 how much of the water storing crystals do I need to use.

Asked by: irishrose2191
You can determine the amount needed by pouring water into the planter. How ever many ounces/cups of water used is the amount of crystals. ie: 8oz of water is 8oz of crystals.

I thought I would have to repot that plant sooner, but the water crystals help. I actually bought the Water Store Crystals for my crickets & Dubia roaches. The crystals go a long way to provide these insects moisture without drowning them. The water crystals are a bit smaller than Flucker's cricket quencher, but less messy & without the blue dye.

We use the crystals to make "yuck" to sling at each other during a messy game. One Packet makes easily 10 gallons, maybe 12. We let it hydrate overnight but can be sped up with warm water. We add about a one cup/5 gallons of non-toxic tempura paint to add color. It disappears into the lawn and help in retain moisture in our sandy soil.

Rated 5 out of 5 by from Amazing I bought this product to water my feeder insects. 1/4 cup absorbed a whole gallon of water. Would be great for watering plants as well.

Rated 5 out of 5 by from This is a wonderful product! Add these crystals when potting up your plants, and cut your need to water. Add these crystals in the lower layers of soil in a pot. Cut your watering requirements to every other day, or even every third day, during hot weather. I have used this product for 6 or 7 years and am very pleased. You can also use the crystals in pre-potted purchased plants by creating vertical "tunnels" with a knife or awl, then pouring in crystals and covering the surface. Overall, a GREAT product, which saves lots of time and extends the periods between watering.

Rated 5 out of 5 by from ALTERNATE USEAGE ---- KEEP COOL THIS SUMMER I make a summer cooler for myself, family and friends by taking a 3" strip of 45" fabric and sewing it into a tube with a 1/4" seam alllowance (leaving a 2" opening at the CENTER to turn the fabric tube). Then sew across the tube 15" from each end AFTER turning it inside out. Feed 2 LEVEL tablespoons of MIRACLE-GRO WATER STORING CRYSTALS into the remaining CENTER third of the tube, and carefully sew the last opening tightly closed. It seems like a small amount of crystals, but remember, each tiny crystal becomes HUGE after getting wet. Wet the tie in cool water for a few minutes -- I set it in the sink covered with water and you have a FABULOUS tie for use in hot weather (I live in Arizona). My neighbor carries a lunch size hard cooler with ICE WATER in it to refresh (he alternates 2 ties) them during the day. He works outside, and finds it much more comfortable with this ability to keep himself cooler all day. They can be dried out if you live in a climate where it wouldn't be used in the winter. Just make sure that it is completely dry befroe storing. When dry, the crystals will dry into hunks, and then become brittle, and it can be moved around and broken back up into crystals again.

Rated 5 out of 5 by from Miracle-Gro Water Storing Crystals I love the Miracle-Gro Water Storing Crystals!!! I use it in all my containers, and hanging plants. Please follow the directions, use only the recommended amount. When I purchase hanging plants a use a dowel to make a few holes, and put a small amount in the holes. Works like a charm to keep the plants happy all summer!!!

Rated 1 out of 5 by from Stay away from this product... I purchased this product to make sure the plants remained hydrated while I was away. It worked fine until we had a deluge - 3 inches of rain in 24 hours. The crystals swelled to the point that the turned into gel and did not released the moisture back into the soil. It killed two of my plants because the soil in the pot swelled to the point that the pot broke. The other pots where I did not use the crystals did fine and those plants are healthy.
