MORE SCIENCE, FEWER BOTTLES.


HEAVY 16 USES A POWERFUL COMBINATION OF MINERAL AND NATURAL INGREDIENTS IN A SYSTEM THAT IS STRAIGHTFORWARD TO APPLY AND MAINTAIN

  • Use HEAVY Finish in soil AND foliar feedings! ๐Ÿ’ฆ

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 plantโ€™s genetic composition by cleaning unwanted build-up of common impurities. 

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

  • When itโ€™s time to take your flowers to the next level ๐Ÿ”ฅ

HEAVY FIRE is a hand-crafted P/K booster built with real nutritional chemistry behind it โ€” 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 1โ€“2 weeks of veg and ramp it through the entire bloom cycle. Youโ€™ll get early support before flower set, stronger late-phase (โ€œCascadingโ€) phosphorus delivery, and all the ingredients needed for a bigger, more resilient root mass with fuller, more branched foliage ๐Ÿ’ฅ

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 โ€” itโ€™s one bottle that simplifies your regimen and brings out the full potential locked in your plantโ€™s genetics. ๐Ÿ”ฅ๐ŸŒฑ

  • ๐Ÿงช Decades in the making, engineered for results!

Heavy 16 isnโ€™t just another nutrient line โ€” itโ€™s the product of a lifelong obsession with plant science, agricultural chemistry, and horticultural efficiency. Born in the gardens of Southern California and refined with careful field testing, our formulas were originally developed to meet the real-world demands of high-performance growers.

Every product in the Heavy 16 lineup was built from the ground up with:

โš—๏ธ Pharmaceutical-grade raw materials for superior uptake
๐Ÿงฌ Multi-path nutrient delivery systems for redundancy and resilience
๐Ÿงซ Micro-batch production for full-spectrum quality control
๐Ÿง  Intelligent ratios of macro/micronutrients, chelators, and biological co-factors

We spent years field-testing with top-tier California farmers โ€” tuning and retuning until every bottle was dialed for maximum translocation, consistency, and performance.

The result? A lean, efficient, highly concentrated nutrient system that gives you all the complexity of modern plant science โ€” in a format thatโ€™s easy to run, easy to scale, and ridiculously effective in flower.

We donโ€™t do hype. We do real R&D โ€” and the difference is in the yield ๐ŸคŒ

  • More than just a root promoter! ๐Ÿ’ฆ

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 isnโ€™t all it can do! ๐ŸŒฟ

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 ๐Ÿœ

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! ๐Ÿ’ง

  • Picking up only the best ๐Ÿ˜Ž๐Ÿค˜

Veg A&B delivers balanced macros + micros, multiple forms of nitrogen and calcium, and a steady nutrient release that builds strong roots, thick tissue, and a resilient structure that can handle high light and COโ‚‚ ๐ŸŒฟ

Bud A&B picks up right where Veg leaves off, pushing density, oil production, and overall quality with highly bioavailable P/K, premium chelators, and elevated trace elements for a true top-shelf finish ๐Ÿš€

Both are crafted with HEAVYโ€™s premium raw inputs and micro-batch blending, giving you a clean, powerful, streamlined base that works in hydro, coco, or soil โ€” without complicating the feed chart ๐ŸคŸ

Use Veg A&B + Bud A&B as your foundation, stack your favorite HEAVY additives, and youโ€™ve got everything your plants need from start to finish! ๐Ÿ‘Š

  • HEAVY is here to bring your garden to the next level ๐Ÿš€

The HEAVY lineup was created with both science and growers in mind โ€” leaning on simplicity of use, without sacrificing the complex chemistry that sets our lineup apart ๐Ÿงช

Kick things off with Veg A&B โ€” 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 โ€” restoring medium balance, flushing excess salts, and sharpening color, aroma, and final weight.

Strong start. Stronger finish. ๐Ÿ’ช
