Heavy 16 Bud A & B is the highest grade bloom nutrient on the Planet. It’s a bold statement, but years of controlled trials and positive customer feedback affirm that claim. It is no wonder to us why every grower we change over to Heavy 16 Bud never goes back to the base bloom nutrients they were using before. It’s because Bud embodies the next level of nutrient brewing craftsmanship and quality. It represents our new-school plant nutrition philosophies that achieve the finest crop quality and yield. Quality farmers and world class plant breeders love The Heavy 16 Bud because of its simplicity, and its unique ability to express the desired traits of top genetics. Heavy 16 Bud does not require a long list of "add-ons". "Simple and effective" is our motto when it comes to all of our products, yet still retaining ultra high quality and a craftsman level of detailing. Heavy 16 Bud has been representing this to the fullest from the beginning.
