The smaller the size, the less time it will take to absorb the water. For 1.5-2mm size in 2-3h you could have them hydrated, 2.5-3mm balls in 4-5h. For 6-8mm balls you will need at least 10h to reach 30mm and up to 48h to reach 50mm.


They are used both as a fun experiment for children, as decoration and also for gardening, as once they have absorbed water, they will gradually release it, which makes them very useful for plant maintenance.

Colours: Blue Balls, Red Balls, Green Balls, Yellow Balls, Orange Balls, Transparent Balls and Multicoloured Balls.
