Liquid KoolBloom (0-10-10) is used at the onset of flowering to initiate a faster blooming response and increase essential oil production for heavier, more flavorful fruits and larger, more fragrant flowers. This highly-soluble bulking agent is designed to compliment other General Hydroponics fertilizers including the Flora, Nova, and Maxi series nutrients.

Dry KoolBloom (sold separately) is added during the last two weeks of development to facilitate ripening and add a final bloom boost.
