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.

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

NOW EVEN MORE AFFORDABLE 🚨

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! 💧

  • HEAVY Prime is as versatile as they come! 💪

HEAVY 16 is developed on an organic acid pH scale, as opposed to the common mineral acid pH scale. Because of its buffering or “friendliness”, organic acids allow for optimum microbial development. Hence, HEAVY PRIME is not only a microbial feed, but also naturally functioning pH regulator. To grasp the difference between organic acid and mineral acid, think of orange juice representing organic acid and battery acid representing a hard mineral acid – which is seen in most “pH down” products.

If your water source is roughly between 5.5 and 8.0 on pH scale, PRIME’s complexion will naturally titrate pH, eliminating the need for hard acids in the garden.
