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.

  • 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. 🌿 #HEAVY16 #HEAVY16Nutrients #PPM #GrowWithHEAVY #Hydrofarm
  • We make using HEAVY Foliar as simple as possible! Read this caption and take notes… 📝 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. #HEAVYFoliar #FoliarSpray #HEAVY16 #HEAVY16Nutrients #GrowWithHEAVY
  • Rocking the HEAVY tank in the garden 🪏😎 @mwreikiroom Even if she isn’t running HEAVY nutes on this veggie garden, she’s still repping! It’s all about the HEAVY mindset — heavy harvests, all the time 👊😎 Looking good! #HEAVY16 #HEAVY16Nutrients #HEAVY16Fam
  • Flat flower? Thin aroma? Missing that full-bodied flavor your genetics should be expressing? 🌱 It might not be your cultivar: it might be what’s happening beneath the plant. HEAVY PRIME is built to fuel the root zone from veg through finish, supporting the biological activity and nutrient conditions that help plants reach their full potential. Designed as a powerhouse microbial feed and sweetener, PRIME helps support microbial populations, improve overall plant nutrition, and create better soil/nutrient conditions for stronger crop performance. At the root of elite flower is an active, well-fed system, and PRIME brings the fuel. With a layered formulation featuring humic and fulvic acids, amino acids, B vitamins, kelp, phytohormones, carbohydrates, trace minerals, and multiple potassium sources, PRIME helps support nutrient transport, metabolic function, microbial energy, and the natural processes that drive better flavor, aroma, resin, and plant performance. That means louder terpene expression. Richer aroma. Improved sweetness and density. And flower that tastes as good as it looks. PRIME doesn’t contain live microbes itself — it feeds and supports the biological engine already working in your media, compost teas, inoculants, and root zone. It’s not just another additive. It’s the foundation underneath the finish. No more cardboard terps! 🚫📦 #HEAVY16 #HEAVY16Prime #GrowWithHEAVY #Prime #Hydrofarm
  • Use HEAVY Finish in soil AND foliar feedings! 💦 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 plant’s genetic composition by cleaning unwanted build-up of common impurities. Use HEAVY FINISH in low dosage as directed through a plant’s life cycle, and a larger dose for the final flushing before harvest. #HEAVY16 #HEAVY16Nutrients #HEAVYFinish #Foliar #GrowWithHEAVY
  • Grow your FIRE with HEAVY FIRE🔥 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. 🔥🌱 #HEAVY16 #HeavyFire #Heavy16Fire #H16Fire #Flowering
  • A root promoter, and a lot more 🤘💦 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 isn’t all it can do! 🌿 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 🐜 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! 💧 #GrowSmart #GrowYourOwn #GrowWithHEAVY #Indoor #Outdoor
