Heavy 16 – FINISH

Heavy Finish aids in achieving an electrochemical balance because it is both a donor and receptor of electrons. When used as a final media flush, the result is a purer soil. That is because Heavy Finish contains natural chelating structures that have been scientifically enhanced in the laboratory, achieving a streamlined and uniform molecular size. Heavy Finish has aided in reclaiming used or imbalanced soils while making nutrient programs available. Heavy Finish can also help cleanse sub-par nutrient regimens via extreme levels of pH and PPM/EC buffering capacity This helps eliminate the threat of heavy metal exposure and all things bad about some unrefined and undefined nutrient programs.

In the tradition of fine viticulture, Heavy Finish is the pure essence of the finest soil terroir. When using Heavy Finish during flower senescence, you can observe the deepest and heaviest aromas and colors your crops’ genetics can express. Some growers choose to use Heavy Prime with Heavy Finish in the final week for added natural aromatic fragrances, while others choose a more minimalist approach by solely using Heavy Finish with pure water.

The bottom line is, no matter what your growing objectives may be, Heavy Finish is the ultimate finite resource for achieving horticultural superiority.

heavy FINISH – NATURAL PRODUCT BLEMISHES

Heavy Finish is an ultra-fine organic acid product that is derived from an ancient deciduous hard-wood forest.  It is extracted with cold water and very minimally treated for stability to maintain its chemical structure and organic complexing abilities.  Cloudiness or white fungal growths may occur from time to time, yet this is normal and the product is considered fine for use.

Also, from time to time, the products’ color can vary from amber to grey. This is a normal occurrence and is not a concern to efficacy.

  • 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. 🔥🌱

  • Need some tips on how to use HEAVY Foliar? You came to the right place! 📝

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.

  • Cheers to good food, good company, and strong roots. Happy Thanksgiving from HEAVY 16! 🍂🦃
  • The real magic starts below the surface 👀

When you run HEAVY 16, you’re not just feeding your canopy — you’re building a root system that can’t be stopped. 🌱🔥

HEAVY’s approach fuels explosive root hair production, and those tiny hairs are everything. Root hairs massively increase the plant’s absorption zone, pulling in more water, more minerals, and more energy to drive serious growth. More root hairs = more fuel for monster plants ⚡️

This isn’t just about thick roots: it’s about building a foundation that sets your entire garden up for success. A dense, aggressive root network gives your plants the power to stack heavy once they hit flower, pumping nutrients upward to support top-tier structure, aroma, and resin.

  • The most complete base nutrients in the game 🌿😎

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 CO₂ 🌿

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 🚀

Both are crafted with HEAVY’s premium raw inputs and micro-batch blending, giving you a clean, powerful, streamlined base that works in hydro, coco, or soil — without complicating the feed chart 🤟

Use Veg A&B + Bud A&B as your foundation, stack your favorite HEAVY additives, and you’ve got everything your plants need from start to finish! 👊
