Saves 90% of water - because Hozelock water storing gel & feed is the fastest acting gel available (50 times faster than nearest competitor) it acts quick to lock water into the compost. This reduces the amount of water that is wasted either by running out of the bottom of the plant pot, or due to evaporation. Only water once per week - when the water storing gel is mixed into the compost, it forms a series of miniature water reservoirs around the roots of the plant. This means that for most of the year plants in containers only need to be watered once per week. Supplies a constant supply of water & nutrients to your plants - the gel is mixed with a slow release food. The food lasts for up to 12 months and supplies a balanced supply of nutrients to the plants as they need it. The water stored in the compost is released to the plant slowly as and when it is required.
