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.

  • HEAVY FOLIAR is Liquid Gold 🏆

Foliar feeding isn’t just hype—it’s science. When you spray nutrients directly onto the leaf surface, plants can absorb them up to 10x more efficiently than through their roots. Why? Because leaf tissue has tiny pores (stomata) that can take in dissolved minerals almost instantly, bypassing the slower, soil-based uptake process.

But that’s not all.

Foliar feeding doesn’t just benefit the leaves—it kickstarts activity underground too. When plants photosynthesize more efficiently due to optimal nutrition, they release more carbohydrates into the root zone. These sugars act as food for beneficial microbes, helping them multiply and thrive, which in turn makes even more nutrients available to your plants.

The result?

• Improved micronutrient delivery
• Enhanced microbial life in the soil
• Stronger roots
• And ultimately—bigger, better yields

That’s why foliar feeding with HEAVY Foliar is a win-win—for your plants, your soil, and your harvest.

  • It all starts here 🌿🚀

HEAVY VEG A & B were born from years of hands-on plant production and advanced nutrient chemistry. Their purpose? To kickstart the development of larger vascular systems and strong structural integrity—so your crops are ready to bear heavy fruit come bloom time.

It’s important to remember: both overfeeding and underfeeding can quietly harm your plants and microbes, even if everything looks fine. HEAVY16’s balanced formulas are designed to correct those hidden imbalances, giving you the freedom to push your grow creatively while staying buffered and stable.

These powerful veg nutrients are built for high-demand cropping systems, focusing on cellular structure and tissue strength at the molecular level—from leaves to shoots to roots. When minerals are missing during key developmental phases, you get microscopic weak spots. That’s why we say: it’s all about the Veg. And HEAVY16 Veg A & B are our way of backing that up.

If you’re aiming for vigorous, healthy plants with massive root mass and rock-solid structure, start from day one with HEAVY16 Veg A & B—whether it’s for your crop material or mother stock. Build it right from the beginning 🌿

  • Where HEAVY VEG leaves off HEAVY BUD will begin 🚀

HEAVY BUD A&B will aid in building larger, more integrated roots, foliage, and vascular systems, in addition to heightened fruit set and quality.

The chemistry of BUD A&B contain the most plant bio-available versions of Phosphorous and Potassium plus micronutrients to ensure superior quality and yields 💪

Exotic trace elements, and our multiple forms of Calcium back up traditional mineral nutrition 🌿

It is because of this perfection in chemistry that you can run our select enhancers or your special additive regiment to achieve the highest quality crops possible!

Quality fruit comes from healthy plants that are put under a certain degree of stress as they fully senesce. HEAVY BUD A&B are revolutionary in this process because they are made in such a way as to correctly push the cellular limits of this stress while allowing for both complex and high-quality nutrition to enter the plant allowing you to increase the amount of dry matter (more yield), limit the amount of water weight, and increase the flavor and taste complexities 🔥
