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 bud a & B

Heavy 16 Bud embodies the next level of nutrient brewing craftsmanship and quality. It represents our new-school plant nutrition philosophies that achieve the finest crop quality and yield. Quality farmers and world-class plant breeders love the Heavy 16 Bud because of its simplicity, and its unique ability to express the desired traits of top genetics. Heavy 16 Bud does not require a long list of “add-ons”. “Simple and effective” is our motto when it comes to all of our products, yet still retaining ultra-high quality and a craftsman level of detailing.

When getting into the nuts and bolts of what makes Heavy 16 Bud A & B tick, think about where the Veg leaves off and where the Bud will begin. As the Veg does all that its description entails, the Bud will take all those same attributes of building larger, more integrated roots, foliage, and vascular systems, and add to this a heightened fruit set and quality. The chemistry of Heavy 16 Bud contains 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 are able to 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. The reason why Heavy 16 Bud is revolutionary in this process is because it was 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. This allows you to increase the amount of dry matter (more yield), limit the amount of water weight, and increase the flavor and taste complexities.

Heavy 16 Bud is the true embodiment of the years of experience in the field that gave us respect for traditional ways while harnessing the current horticultural technology platform we are at. Just like any good farmer would.

heavy BUD b – NATURAL PRODUCT BLEMISHES

Heavy Bud 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.

  • No need to pH when you’re running HEAVY 💪

PRIME, our centerpiece, sets the pH for you via complex organic acids! 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 🌱

One less step in your routine so that you can spend time where it matters most! 😎

  • Need some tips on how to use HEAVY Foliar? You came to the right place! 📝

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.

  • Less bottles. More growth. 🌱

HEAVY 16 Veg A+B, like all of our products, was built different: a true two-part base designed to carry your plants through veg with everything they actually need (and nothing they don’t). No bloated feeding charts. No stacking endless additives just to get results.

Just precise, balanced nutrition, dialed in from the start.

HEAVY 16 in general is engineered around a streamlined, potent system that delivers complex formulas through simple application. And instead of chasing EC/PPM targets, you’re feeding in clean mL-per-gallon measurements. This makes consistency effortless, from small runs to full rooms!

What that means in practice:

• Fewer inputs per feeding
• Lower overall nutrient usage
• More predictable results
• Less time mixing, more time growing

Veg A+B lays the groundwork for everything that comes next: building strong vascular systems, structural integrity, and root mass so your plants can actually handle heavy inputs later in flower 🌺 

When it’s all said and done, HEAVY delivers: a balanced, high-performance veg formula that improves overall plant nutrition and optimizes conditions for real growth 🤘

  • 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.
 
One less step in your routine so that you can spend time where it matters most!

  • FIRE helps create larger, more robust flowers, so why start in veg? 🔥

HEAVY 16 is built around a Cascading Delivery system. We have incorporated slow medium and quick release forms of our phosphates into our FIRE! 🧪

By administering low levels in the last one to two weeks of veg and going through the entire bloom cycle with a gradual ramp, your providing pre-bloom stimulation, maintaining tighter nodal regions for larger flower/fruit development, and supplying intermediate and late-phase #CascadingDelivery of Phosphorous 📈.

Not to mention, running Heavy Fire in the late phase of veg will provide for a larger, more resilient root mass, and create larger, more branched foliage. Setting up your crop for a HEAVY tier finish! 🤜🤛
