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 bud a & B

Heavy 16 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.

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, and our multiple forms of Calcium back up traditional mineral nutrition. 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.

Quality fruit comes from healthy plants that are put under a certain degree of stress as they fully senesce. The reason why Heavy 16 Bud is revolutionary in this process is because it was 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. This allows you to increase the amount of dry matter (more yield), limit the amount of water weight, and increase the flavor and taste complexities.

Heavy 16 Bud is the true embodiment of the years of experience in the field that gave us respect for traditional ways while harnessing the current horticultural technology platform we are at. Just like any good farmer would.

heavy BUD b – NATURAL PRODUCT BLEMISHES

Heavy Bud 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 Finish: the final statement! 🌿

This all-natural bio-regulator transforms water at the molecular level, making it more active and able to penetrate deeply into soil and media. It balances electrochemistry by donating and receiving electrons, unlocking the full expression of your crop’s genetics 🧬

Use it in your final week to reclaim tired soils, buffer EC and pH, and purge out residual salts or heavy metals from sub-par regimens. Its natural chelating structures are lab-refined to a uniform size that cleans far deeper than typical finishing products 💦

Expect deeper color, heavier oils, and richer aromatics during flower senescence — the kind of results that elevate good runs into great ones. Some growers pair it with Heavy Prime for extra terp lift, others run it solo with pure water for a clean, powerful finish 🔥

However you use it, Heavy Finish is your go-to for the final flush that actually finishes. 💧🌱

  • Keep your pH balanced from start to finish with PRIME 👌

HEAVY 16 is developed on an organic acid pH scale, as opposed to the common mineral acid pH scale. Because of its buffering or “friendliness”, organic acids allow for optimum microbial development. Hence, HEAVY PRIME is not only a microbial feed, but also naturally functioning pH regulator. To grasp the difference between organic acid and mineral acid, think of orange juice representing organic acid and battery acid representing a hard mineral acid – which is seen in most “pH down” products.

If your water source is roughly between 5.5 and 8.0 on pH scale, PRIME’s complexion will naturally titrate pH, eliminating the need for hard acids in the garden.
 
One less step in your routine so that you can spend time where it matters most!

  • Want your flower to stand out in a sea of green? 🤌

It 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.

  • A root promoter, root protector, and drip cleaner/anti-precipitate all in one! 💦

As a root promoter, Heavy Roots will increase branching of lateral roots, but more importantly, it will significantly increase the quantity and size of the true absorption zone, the root hair 🌿

As a root protector, Heavy Roots will elicit naturally induced resistances, or specifically, give the plant a complex layer of systemic acquired resistance (SAR). Tapping the plants evolutionary predisposition to ward off pestilence, we promote these hidden genetic gems through extremely fine derivatives. The result is that the plant becomes more resilient against fungal pathogens as well as insects 🐜

As a drip cleaner and anti-precipitate, Heavy Roots, through its outstanding composition of natural ingredients, will protect against lockout caused by poor water or base nutrients, exotic nutritional programs or faulty mixing methodologies. Heavy Roots will also keep your equipment and media free from salt buildup and scale! 💧
