      • Why isn’t HEAVY 16 based off of a PPM Scale? 📝

PPM’s have long been used to gauge nutrient strength in irrigation water. While this method can still be employed, HEAVY16 utilizes a cascading delivery system with multiple nutrients that have no charge out of the bottle, and therefore won’t register on an EC or PPM meter. These neutral organic minerals have a potent nutritional value that becomes available to your plants over time. Hence, we prefer to use specific dosing increments (mL) per gallon to measure fertility versus PPM’S 🧪

You can still use the PPM/EC scale as a judgment tool when auditing your water chemistry over time. Additionally, we do recommend using such measurements when assessing the hardness of your water and efficacy of your filtration system. 🌿

      • Feed your rhizosphere the way it deserves! 🌱💥

HEAVY ROOTS is a next-gen additive that hits every angle of root development—packed with multiple functions in one bottle, minus the hormones that can drag down yield or quality.

Root promoter ✅ Root protector ✅ Drip system cleaner ✅ Anti-precipitate ✅

All-in-one, no fluff.

From clone to the final flush, add ROOTS first to your reservoir at just 1mL per gallon before your usual nutrients—and watch the magic happen. The real power? It’s in the root hairs—those delicate, fluffy white zones that do the heavy lifting when it comes to water and nutrient uptake. ROOTS boosts both the size and number of these absorption powerhouses, expanding the root zone like crazy and unlocking faster, more vigorous growth from the inside out.

More root hairs = more uptake = healthier, more resilient plants ready to perform.

Let your roots do the talking! 🗣️

      • Big results start in small batches 💧

At HEAVY, every formula is crafted with intention, not mass-produced. Our micro-batch blending means every drop is mixed, tested, and perfected under the same principles that built the brand:

🌿 Use only the highest-grade ingredients on the planet

⚗️ Deliver complex chemistry in an easy-to-use form — more science, fewer bottles

🧪 Maintain total quality control and peak freshness through small-scale brewing

It’s not just nutrients: it’s precision horticultural chemistry, designed for growers who demand the best from every run! 🤜🤛

      • HEAVY Finish isn’t just a flush — it’s a 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. 💧🌱
