Liquid KoolBloom is a bulking agent that goes way beyond other bloom boosters. Enriched with stress-reducing vitamins and nutrient transporting acids, it promotes heavy production of essential oils, fantastic flavors, and increases fruiting and flower development. Liquid KoolBloom should be used at the start of the reproductive cycle initiating larger, heavier fruits and flowers. During the last two weeks, use Dry KoolBloom for an additional bloom boost and to facilitate ripening.
