View Feed Schedules: Heavy 16 Basic Feed & Foliar Recipe | Heavy 16 Dosatron Feed | Heavy 16 Outdoor Feed

Mixing procedure

  • Fill reservoir with water (filtered preferred, but not required)
  • Add HEAVY 16 products in order listed on feed chart (shake each bottle well)
  • Rinse measuring cup after dosing each individual product
  • Do not use airstones in reservoir: gentle circulation is preferred
  • HEAVY 16’s natural and mineral formulation is Grower-Engineered™ for mL per gallon dosing versus EC/PPM dosing
  • For accuracy and optimum fertility, mixing at recommended rates will yield best results
  • Shake well; settling is normal.

pH

  • When using HEAVY PRIME with HEAVY 16 nutrients, do not adjust pH: 5.5 – 6.5pH is an acceptable starting range
  • Ideal irrigation will produce 10% runoff with a pH rise of approximately 0.5
  • If runoff pH rise is higher than 0.5, plants require more frequent or longer feedings

LONGER CROP CYCLES

  • For mother plants, use VEG Week 2 dosage
  • For longer VEG cycle, duplicate VEG Week 2 dosage until BUD
  • For longer BUD cycle, duplicate BUD Week 6 dosage. When ready, resume with BUD Week 7 onward

INOCULATING FLUSH

  • 1-2mL Prime, 1mL Roots, 2.5mL Finish plus a Bacterial Inoculant of your choice
  • This vigorous inoculation is a fresh carbon source, resetting PH and breaking down salts through organic complexion
  • You will want to mix and apply every 7-10 days

  • Wishing everyone an awesome Halloween! 🎃

Stay safe out there and have a blast, from your friends at HEAVY! 👻

  • GROW YOUR FIRE! 🔥

Heavy Fire is a versatile bloom supplement that can, because of its ingredients, be incorporated into any existing plant system and nutrient program. This premium blend of PK and other essential bloom ingredients is what it takes to grow the biggest and best flowers you can, by increasing flower formation rate and maturation.💥

Starting Heavy Fire in the last week of veg and going through the entire bloom cycle with a gradual ramp will provide your entire pre-bloom stimulation, intermediate and late-phase ripening nutritional, and phyto-hormonal needs – all culminating in big buds, tasty flowers, and a harvest you can be proud of 🔥

  • Same family. Same aroma magic! 🍃✨

Hops and another famously “aromatic” (😉) plant come from the same botanical family — which is why their terpene profiles are so strikingly similar. Think bold, sticky, citrusy, floral notes that fill the air and make growers (and brewers) smile. 🍻🌱

And here’s the best part: HEAVY 16 nutrients deliver just as much punch for hops as they do for their more famous cousin. Consistent feeding = stronger plants, richer aroma, and heavier yields. 💪

  • 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! 🗣️
