Welcome to Heavy 16
For years, Heavy 16 Professional Plant Nutrient has been the preferred choice among elite growers across California.
Now, this artisan-grade blend is available to growers around the world.
Heavy 16 breaks free from the hype and hassle of other nutrient lines and eliminates the need for excessive additives by utilizing only the highest-grade ingredients in the most scientifically advantageous formulation on the market.
Heavy 16 is powerful, yet simple. Heavy 16 is a complete two-part nutrient and features all of the essential macro and micro elements that plants require to produce maximum yields of unsurpassed quality.
Heavy 16 performs robustly in soil and hydroponic gardens alike. Used alone, Heavy 16 produces superior crops, but it can also be combined with organic stimulants, compost teas, enzymes, hormones and microbial inoculants for fantastic crop customization.
Heavy 16 is hand-brewed in micro-batches to ensure quality and freshness and each ingredient is refined to ensure purity and consistency. Heavy 16 is committed to this artisanal approach to quality nutrient production. Based on our phenomenal results and customer feedback, we wouldn't have it any other way.
