Heavy 16 – Foliar

In our quest to provide the highest-grade products with superior efficacy to our growers, Heavy 16’s Foliar Professional Plant Additive is hands down the illustration of that mission, with full spectrum plant nutrition being the core of that statement. This revolutionary blend is “so far beyond” in its effects on plant metabolic growth and tissue integrity that many of our growers have eliminated a long list of reoccurring issues.

When sprayed on the foliage of your crop, Heavy Foliar’s net neutral chemistry is easily absorbed into the negatively charged foliage helping to immediately strengthen the canopy on its eventual journey to the roots. As the carbon-based concentration and mineral nutrition moves throughout the plants vascular system, the result is more elastic tissue, more adaptive membranes, as well as heightened yields at harvest. The amount of quality Calcium in Heavy Foliar is key to this elasticity and structure as it provides a perfect bridge between phospholipids, glycolipids, and proteins in the cell membrane.

Heavy Foliar supports vigorous growth and photosynthesis. The result of this influx of carbon-based molecules ultimately aids the plants’ ability to make and store its own necessary carbon and energy, i.e. the variables of a high quality yield.

We recommend using Heavy Foliar before perceived stressful events, i.e., spraying mother plants before taking cuttings, before transplanting, before transition periods, and before nights of freezing temperatures or extreme daytime heat.

Heavy Foliar Synergistically provides a single spray pass made by the grower, as the neutral based chemistry can be combined with any foliar applied compost/biological teas, pest control products, organic oils, any surfactant product, sulfur/fungicide, etc.

NATURAL PRODUCT BLEMISHES

Heavy Foliar is a complex chemistry of plant available carbohydrates and multiple forms of Calcium.  The vinegar smell is normal and part of the acetate chelation and fermentation in the bottle.  Also, from time to time, the products’ color can change from vibrant green to dark green.  This is a normal part of the fermentation process that still occurs after bottling and is not a concern to its efficacy.  The pH of Heavy Foliar should be in the 3.0 range, which is normal and the basis of our organic acid philosophy.

  • 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.

  • 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! 🚫📦

  • Bring the HEAT with 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. 🔥🌱

  • 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.

  • 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! 💧
