It contains the nutrients needed to enhance the production of robust blooms as well as essential oils and fragrance in many flowers and culinary and medicinal herbs. KoolBloom is part of a blooming feeding regimen. We recommend starting with Liquid Koolbloom during the early stages of blooming following feed chart instructions. Switch to KoolBloom only during the last 1-2 weeks of flowering to promote ripening in plants.
