Heavy 16 – Base Theory

Our Base nutrients represent our mission at HEAVY16. 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 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. 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 VEG A & B

The Heavy 16 Veg A & B formula embodies years of plant production experience and nutrient chemistry. Its ultimate function is to begin the process of achieving crops with larger vascular systems and structural integrity to support Heavy fruit loads in the bloom cycle. Understand the fact that both under and over-fertilization are detrimental to your plants (and microbes) even when the visual appearance is good. Heavy 16’s chemistry helps to eliminate these imbalances and create a platform to get creative but stay buffered.  Heavy 16’s diverse vegetative nutrients address intense cropping systems collectively with cellular structure and tissue integrity at the core of what we are talking about. Think of plant cells and tissue at the molecular level in leaves, shoots and roots. Now think of the microscopic holes that will happen when minerals are unavailable in the building process.

From our standpoint, it’s all about the Veg, and Heavy 16 Veg A & B is formulated to prove we practice what we preach. Simply put, you want to build beautiful, strong, well-integrated plants with large root mass in the Veg so they can take the abuse when you really hammer them in the flowering phase. This makes it imperative that you use Heavy 16 Veg A&B from day one on crop material and mother stock to ensure integrity starts from the beginning.

heavy veg b – NATURAL PRODUCT BLEMISHES

Heavy Veg B is derived from potassium and sulfur forms that employ an organic inert clay carrier that can cause intermittent cloudiness when shaken.  This cloudiness is completely normal and considered part of the products characteristic.

HEAVY BUD A&B will aid in building larger, more integrated roots, foliage, and vascular systems, in addition to heightened fruit set and quality.

The chemistry of BUD A&B contain the most plant bio-available versions of Phosphorous and Potassium plus micronutrients to ensure superior quality and yields 💪

Exotic trace elements, and our multiple forms of Calcium back up traditional mineral nutrition 🌿

It is because of this perfection in chemistry that you can run our select enhancers or your special additive regiment to achieve the highest quality crops possible!

Quality fruit comes from healthy plants that are put under a certain degree of stress as they fully senesce. HEAVY BUD A&B are revolutionary in this process because they are made in such a way as to correctly push the cellular limits of this stress while allowing for both complex and high-quality nutrition to enter the plant allowing you to increase the amount of dry matter (more yield), limit the amount of water weight, and increase the flavor and taste complexities 🔥

  • No more cardboard terps 🚫📦

Top-shelf flower starts with flavor, aroma, and resin-rich potency—and that’s exactly where HEAVY 16 PRIME shines. 🌺🔥

PRIME is a powerhouse microbial feed and sweetener, crafted to elevate oil production, boost brix levels (hello sweetness + density), and bring out those unique terpene expressions that set your cultivar apart. 🍇🍋🍊

While it doesn’t contain live microbes itself, PRIME supercharges the effectiveness of your microbial inoculants, compost teas, and enriched media. It’s the missing link that brings everything together, feeding the underground life that fuels explosive above-ground quality. 🌱⚡️

Use it through the entire life cycle to dial in plant performance, push genetic potential, and unlock flavor profiles that hit like no other. Taste, smell, potency—PRIME makes sure they’re unforgettable.

  • Feed your rhizosphere the way it deserves! 🌱💥

HEAVY ROOTS is a next-gen additive that hits every angle of root development—packed with multiple functions in one bottle, minus the hormones that can drag down yield or quality.

Root promoter ✅ Root protector ✅ Drip system cleaner ✅ Anti-precipitate ✅

All-in-one, no fluff.

From clone to the final flush, add ROOTS first to your reservoir at just 1mL per gallon before your usual nutrients—and watch the magic happen. The real power? It’s in the root hairs—those delicate, fluffy white zones that do the heavy lifting when it comes to water and nutrient uptake. ROOTS boosts both the size and number of these absorption powerhouses, expanding the root zone like crazy and unlocking faster, more vigorous growth from the inside out.

More root hairs = more uptake = healthier, more resilient plants ready to perform.

Let your roots do the talking! 🗣️

  • Whether you’re in hydro, soil, coco — HEAVY gets the job done ✅

Lil throwback shot from @voodoo_gardens, showing off the root growth running the HEAVY lineup 🚀

HEAVY ROOTS is a powerful all-in-one root additive that works throughout your plant’s entire life cycle—from cloning to just before harvest. It’s designed to boost root growth, protect roots, keep your irrigation system clean, and prevent nutrient buildup—without any yield- or quality-reducing hormones.
Using it is simple: Add HEAVY ROOTS first to your reservoir at 1mL per gallon, then follow with your usual nutrients and additives.

This formula not only encourages strong lateral root branching but also greatly increases the number and size of root hairs—the fine, fluffy white parts of the root system responsible for most water and nutrient absorption. More root hairs mean a bigger surface area for uptake, faster growth, and a stronger, more resilient plant! 🌱

  • The gold standard of foliar sprays 👑

FOLIAR is our mission in a bottle — full-spectrum plant nutrition at its peak. This revolutionary blend pushes plant metabolic growth and tissue integrity “so far beyond” that many growers have eliminated recurring issues altogether.

Sprayed on foliage, HEAVY FOLIAR’s net-neutral chemistry is rapidly absorbed, strengthening the canopy as it moves to the roots. Its carbon-based minerals — especially high-quality calcium — boost tissue elasticity, adaptive membranes, and yield potential.

By fueling photosynthesis and carbon storage, FOLIAR supports vigorous growth and top-tier harvest quality. Use before stress events: taking cuttings, transplanting, transitions, or extreme temps 🌡️

Compatible with virtually anything — compost teas, pest control, organic oils, surfactants, sulfur, fungicides — in a single pass 💪

PRIME, our centerpiece additive, sets the pH for you via complex organic acids. If your source water is roughly between a 5.5 and 8.0 on the pH scale, PRIMES complexion will naturally titrate the pH, eliminating the need for hard acids in the garden 🌿

PRIME’s chemistry allows for flexibility throughout cultivation systems and alternative feeding programs from aeroponics to outdoor soil crops. Primes superiority to other products including proprietary derivatives and mixing procedures will eliminate your need for multiple other additives that would be considered redundant or incomplete according to our data 💸

Carbohydrate complexes, L-amino acid and B vitamin supplements, kelp and natural Phyto-hormone derivatives, and high-grade humic acids are all represented in Primes composition 🔬

Along with these necessary standard constituents, we have added exotic trace element suite, six forms of potassium (including potassium silicate), yeast and plant extracts, ultra-fine low molecular weight fulvic acid, and proprietary organic acids to ensure your crop and its microbial life are optimally fortified and functioning at their peak metabolic/intelligence levels.
