Description
Perlite is a naturally occurring volcanic rock which, when heated to super high temperatures, produces incredibly lightweight, micro-porous granules. When mixed with compost, these granules hold water and nutrients and also improve aeration and drainage in the compost, creating a healthier growing environment and stimulating root development and growth.
Vitax Perlite can be used alone as a seed starting medium. Its structure maintains uniform moisture and temperature levels and its bright white colour provides protection against bright sunlight and high radiant energy. The white colour also reflects light up under the foliage which encourages growth.
