## Description

Color: Purple Package: 10gram (makes over 4 cups of beads) Hydro Crystals are an odorless and pretty soil substitute for indoor plants and vases of flowers! The water crystals can store water for up to 2 months for the plants, without the need for regular watering! Ideal if you are going on holiday or want a unique finishing touch to a glass vase, simply soak the Hydro Crystals in water for 8-10 hours before use.These water crystals are made from Polyacrylamide; a non toxic, biodegradable substance that will help nourish and water your plants. Expanding up to 150 times their original size, our Hydro Crystals will look like colored jelly balls and make fantastic accessories to table centerpieces and flower arrangements! An ideal stocking filler, Birthday or Mother's Day gift, why not place them in a vase full of flowers for the recipient to enjoy and wonder at. Polyacrylamide is also used in cool packs, so why not make full use of your Hydro Crystals! Soak a few in water as the instructions show and put the gel balls in a freezer bag before placing on your forehead to help ease a headache!
