Heavy 16 – Base Theory

Our Base nutrients represent our mission at HEAVY16. From day one, we have been all about our Base. That’s why we started by solely focusing on Veg and Bud. To us, additives should complement a finely tuned Base that has been honed by years of data, and founded on a balance between farming wisdom, proprietary ingredients, and agricultural technology. We have sourced some of the world’s most precious derivatives and we only add the finest virgin and food grade minerals to ensure optimum cascading availability as your reservoir/media pH rise naturally. We pride ourselves in having created a stand-alone base nutrient that in its simplest form can grow an outstanding crop with no other additions. Our Veg and Bud were designed in the Dutch two-part style for ease of use and its ability to harness complex blends. Lastly, as plant scientists we believed that vegetative/leaf crops required a completely different nutritional composition than fruiting/flowering crops, hence Heavy 16 Veg and Bud.

HEAVY VEG A & B

The Heavy 16 Veg A & B formula embodies years of plant production experience and nutrient chemistry. Its ultimate function is to begin the process of achieving crops with larger vascular systems and structural integrity to support Heavy fruit loads in the bloom cycle. Understand the fact that both under and over-fertilization are detrimental to your plants (and microbes) even when the visual appearance is good. Heavy 16’s chemistry helps to eliminate these imbalances and create a platform to get creative but stay buffered.  Heavy 16’s diverse vegetative nutrients address intense cropping systems collectively with cellular structure and tissue integrity at the core of what we are talking about. Think of plant cells and tissue at the molecular level in leaves, shoots and roots. Now think of the microscopic holes that will happen when minerals are unavailable in the building process.

From our standpoint, it’s all about the Veg, and Heavy 16 Veg A & B is formulated to prove we practice what we preach. Simply put, you want to build beautiful, strong, well-integrated plants with large root mass in the Veg so they can take the abuse when you really hammer them in the flowering phase. This makes it imperative that you use Heavy 16 Veg A&B from day one on crop material and mother stock to ensure integrity starts from the beginning.

heavy veg b – NATURAL PRODUCT BLEMISHES

Heavy Veg B is derived from potassium and sulfur forms that employ an organic inert clay carrier that can cause intermittent cloudiness when shaken.  This cloudiness is completely normal and considered part of the products characteristic.

  • 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 🔥
