    • 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. 🔥🌱

    • 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.

    • 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! 👊
