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.

  • Use HEAVY Finish in soil AND foliar feedings! 💦

HEAVY FINISH is a high-quality formulation for mixing of mineral formulas. FINISH can be applied to trees and vines, vegetable and field crops, turf and greenhouses and various ornamental species!

Use HEAVY FINISH to cleanse impurities, express natural plant flavors, and unlock rich, full-bodied aromas. HEAVY FINISH promotes the natural qualities of a plant’s genetic composition by cleaning unwanted build-up of common impurities. 

Use HEAVY FINISH in low dosage as directed through a plant’s life cycle, and a larger dose for the final flushing before harvest.

  • Flat flower? Thin aroma? Missing that full-bodied flavor your genetics should be expressing? 🌱

It might not be your cultivar: it might be what’s happening beneath the plant.

HEAVY PRIME is built to fuel the root zone from veg through finish, supporting the biological activity and nutrient conditions that help plants reach their full potential. Designed as a powerhouse microbial feed and sweetener, PRIME helps support microbial populations, improve overall plant nutrition, and create better soil/nutrient conditions for stronger crop performance.

At the root of elite flower is an active, well-fed system, and PRIME brings the fuel.

With a layered formulation featuring humic and fulvic acids, amino acids, B vitamins, kelp, phytohormones, carbohydrates, trace minerals, and multiple potassium sources, PRIME helps support nutrient transport, metabolic function, microbial energy, and the natural processes that drive better flavor, aroma, resin, and plant performance.

That means louder terpene expression.
Richer aroma.
Improved sweetness and density.
And flower that tastes as good as it looks.

PRIME doesn’t contain live microbes itself — it feeds and supports the biological engine already working in your media, compost teas, inoculants, and root zone. It’s not just another additive. It’s the foundation underneath the finish.

  • Bring the HEAT with FIRE 🔥 

HEAVY FIRE is a hand-crafted P/K booster built with real nutritional chemistry behind it — brewed and aged (not just blended) to create a truly unique, balanced bloom supplement. It slides seamlessly into any nutrient program thanks to its ultra-fine minerals and natural homogenization.

Kick it on in the last 1–2 weeks of veg and ramp it through the entire bloom cycle. You’ll get early support before flower set, stronger late-phase (“Cascading”) phosphorus delivery, and all the ingredients needed for a bigger, more resilient root mass with fuller, more branched foliage 💥

Powered by three forms of phosphorus (including highly effective phosphite), three forms of potassium, and ammonium nitrogen to improve P uptake. Finished with a premium cold-processed kelp mix to naturally support blooming — it’s one bottle that simplifies your regimen and brings out the full potential locked in your plant’s genetics. 🔥🌱

  • We make using HEAVY Foliar as simple as possible! Read this caption and take notes… 📝

HEAVY FOLIAR is highly versatile and can be used alone or with other products. Mixing HEAVY FOLIAR with HEAVY ROOTS and HEAVY FIRE allows a for a comprehensive nutritional delivery in both phases of plant development. HEAVY FOLIAR can be mixed with pesticides, fungicides, soaps or oils.

We recommend spraying every three days for optimal nutrition uptake. If you prefer to spray every day, we recommend using the HEAVY FOLIAR recipe at half strength. For best results, spray your crop from seedling up until the fourth week on flowering crops. Please note that there is no need to adjust the pH of the FOLIAR formula after mixing, but that FOLIAR should be sprayed within three days of mixing!

🌿 Mix HEAVY FOLIAR with water, adding HEAVY16 Products in order as listed on the schedule on our website

🌿 Lightly mist plants every 3 days during foliar periods. Avoid drenching foliage.

🌿 You can spray HEAVY FOLIAR lights on or off; our recommendation is to spray at first light.

🌿 Do not adjust pH of FOLIAR mixture.

🌿 Use FOLIAR mixture within 3 days of dilution with water.

🌿 An oily sheen on leaves is normal.

  • A root promoter, and a lot more 🤘💦

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. But that isn’t all it can do! 🌿

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! 💧
