Vitax Perlite Compost Additive 20L Litre

When mixed with compost, Perlite holds water and nutrients in the compost, producing a healthier growing media. Can be used for seed starting, rooted cuttings, potting-on or planting out. Its bright white colour provides protection against bright sunlight and high radiant energy. It also reflects light under plant foliage to encourage growth. In a 20 litre bag.
