Raingel is a perfect all-in-one hydrator and fertiliser for all of your plants. The gel absorbs water and then it is released as and when required. Because Raingel is also a plant feed a single application will nourish your plants. The crystals swell to absorb water then water is released as needed throughout the season reducing your watering by up to 90%! Only one application is needed to last the whole season. A 150g tub can treat up to 10 x 27cm Hanging Baskets.
