Heavy 16 – Prime

PRIME is an ultra-diverse liquid formulation designed for use at all times of your crops’ cycle. We have formulated Prime to be the centerpiece of the Heavy 16 program, but its chemistry allows for flexibility throughout cultivation systems and alternative feeding programs from aeroponics to outdoor soil crops.

Prime aids in bolstering the development of a robust root system, and eliminates your need for multiple other additives that would be considered redundant or incomplete. Tastes, colors, flavors, and brix levels will all be heightened while expressing the plants true phenotype.

  • Happy Holidays from all of us at HEAVY! 🎄✨

As the year winds down, we just want to say thank you to every grower, partner, and supporter who trusts our nutrients and stands behind what we do! Your passion, dedication, and pursuit of better grows is what drives us to keep raising the bar.

We’re grateful to be part of your gardens and your journey. Wishing you a season filled with rest, good vibes, and big plans for the year ahead. Here’s to bigger yields in the new year 🌱💪

  • 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. 💧🌱

  • The HEAVY 16 centerpiece: PRIME 🟪🌿

Designed to elevate every stage of your crop’s life cycle, PRIME delivers more than just nutrition—it transforms the entire environment your plants thrive in:

✅ Bolsters root development
✅ Fuels microbial populations
✅ Optimizes soil & nutrient conditions
✅ Unlocks true flavor, aroma, and phenotype expression

Why juggle a dozen additives when one bottle can do it all? PRIME is the ultra-diverse liquid formulation that eliminates redundancy and amplifies results, whether you’re running aeroponics, hydro, or soil.

From richer colors and heightened flavors to higher brix levels and stronger yields, PRIME isn’t just another input—it’s the foundation that makes every other piece of your program shine ✨ 

#Heavy16 #Prime #HEAVY16Prime #H16Prime #GrowWithHeavy #CropPerformance #CultivationEssentials
  • Built different by design 💪

Our lineup isn’t about bloated feed charts or unnecessary additives. It’s a streamlined, science-driven nutrient system made with premium raw ingredients and small-batch blending for consistency you can trust. Every formula is designed for maximum bioavailability, so plants get exactly what they need, when they need it.

✔️ Balanced Veg & Bud A&B for strong structure, healthy growth, and heavy yields
✔️ Prime, Fire & Foliar deliver targeted support for roots, terpenes, and overall plant vitality
✔️ Works seamlessly in soil, coco, and hydro
✔️ Clean inputs that support both plants and beneficial microbes

Growers running HEAVY 16 consistently see stronger roots, thicker stalks, healthier plants, and better finishes: without overcomplicating the grow.

  • Balanced flowering nutrition! 🤟🔥

When it comes to the flowering stage, your plants deserve nothing less than premium nutrition. HEAVY BUD A&B is built to deliver just that: a cascading flow of high-quality Calcium, micronutrients, and a proprietary Phosphorous + Potassium blend designed to push plants toward robust, top-shelf yields 🚀

Formulated with low salt-indexed ingredients, exotic trace elements, and four distinct forms of Calcium, this powerful base nutrient fuels every phase of the bloom cycle with precision and consistency. The result? Dense, resin-packed flowers and vibrant health from start to finish 🤌

Ready to take your flowering game to the next level? Use BUD A&B throughout your entire bloom cycle, following our custom nutrient schedule here at heavy16.com/nutrient-calculator 👊

  • More than just a root promoter! 💦

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! 💧

  • HEAVY takes you higher ⬆️😎

Switching to HEAVY 16 does more than just change up your plant food: it supercharges your crop from root to bloom. Our streamlined nutrient system (Veg A&B → Bud A&B → Prime + Fire + Foliar) delivers deeply bioavailable macros, micros, and calcium, fueling vigorous root growth, thicker tissue, and higher-yield flowers 💐 

Growers who make the switch often notice stronger root mass, more robust structure, and denser final yields — because HEAVY 16 was built with “more science, fewer bottles.” 🧪

  • 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.

  • Full-spectrum nutrition for a top notch finish 🚀

The HEAVY lineup was created with both science and growers in mind — leaning on simplicity of use, without sacrificing the complex chemistry that sets our lineup apart 🧪

Kick things off with Veg A&B — balanced macros/micros + multiple calcium and nitrogen sources that build strong structure and vascular strength from day one. Pair it with Prime to boost microbial life, improve soil chemistry, and elevate brix, aroma, and overall plant vigor.

As bloom begins, Bud A&B steps in with fast-acting P/K and enhanced trace elements for dense, high-quality flowers. Layer in Fire for a powerful late-phase P/K ramp that drives heavy stacking, resin, and true genetic expression.

Support the whole run with Foliar for direct leaf-fed calcium and micros, helping with tissue strength and stress resistance. Then close the cycle cleanly with Finish — restoring medium balance, flushing excess salts, and sharpening color, aroma, and final weight.

Strong start. Stronger finish. 💪

  • When it’s time to take your flowers to the next level 🔥

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. 🔥🌱
