Heavy 16 Bud A&B




Professional flowering base nutrient by Heavy 16, designed to fuel plants with complex ingredients to drive quality and yields to astounding heights.

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. 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.

Heavy 16 – Base Theory

Our Base nutrients represent the mission here at Field 16. From day one, we have been all about our Base. That’s why we started by solely focusing on Veg and Bud. To us, additives should complement a finely tuned Base that has been honed by years of data, and founded on a balance between farming wisdom, proprietary ingredients, and agricultural technology. We have sourced some of the world’s most precious derivatives and we only add the finest virgin and food grade minerals to ensure optimum cascading availability as your reservoir/media pH rise naturally. We pride ourselves in having created a stand-alone base nutrient that in its simplest form can grow an outstanding crop of unsurpassed quality with no other additions. Our Veg and Bud were designed in the Dutch two-part style for ease of use and its ability to harness complex blends. We also believe in a professional approach to nutrient systems, so we bypassed the third bottle or thick glue-like chelating agents. Lastly, as plant scientists we believed that vegetative/leaf crops required a completely different nutritional composition than fruiting/flowering crops, hence Heavy 16 Veg and Bud.

Heavy 16 – BUD A & B

When getting into the nuts and bolts of what makes Heavy 16 Bud A & B tick, think about where the Veg leaves off and where the Bud will begin. As the Veg does all that its description entails, the Bud will take all those same attributes of building larger, more integrated roots, foliage, and vascular systems, and add to this a heightened fruit set and quality. The chemistry of Heavy 16 Bud contains the most plant bio-available versions of phosphorous and potassium plus micronutrients to ensure superior quality and yields. Exotic trace elements, natural high-grade chelators, and multiple forms of calcium back up the traditional mineral nutrition with a synergism that is second to none. It is because of this perfection in chemistry that you are able to run our select enhancers or your special additive regiment to achieve the highest quality crops possible.


  • Cascading delivery of both organic and mineral calcium and micronutrients
  • Natural and superior chelation through our ultra-fine proprietary mix of organic acids
  • Exotic trace mineral suite allowing for superior oil content and flavonoid expression
  • High rates of phosphorous and potassium to ensure a significant, high quality harvests
