These water-storing granules produce a saturated gel which retains moisture to reduce the risk of baskets, containers and Flower Pouches™ drying out in the summer. Each granule will hold up to 400 times its own weight in water! Simply add some water retaining gel to the compost to improve growing conditions for your plants, and reduce your time spent watering. 1kg will mix approximately into 1000 litres of compost, or will be enough for 100 30cm (12”) baskets or 60 35cm (14”) containers.
