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.

  • Want your flower to stand out in a sea of green? 🤌

It 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.

  • A root promoter, root protector, and drip cleaner/anti-precipitate all in one! 💦

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 🌿

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! 💧

  • Our founder began formulating this nutrient line based on the demands of many local farmers that he had befriended over his lifetime.

Simply put, HEAVY 16 is based on a few key principles:

🔥 Use only the highest grade ingredients on the planet

🔥 Use complex chemistry for easy application: more science, fewer bottles

🔥 Use Micro-Batch blending techniques to ensure total quality control and peak freshness

And the rest is history 👊
