"MY GOAL WAS TO CREATE A NUTRIENT SYSTEM FOUNDED ON MODERN AND PROVEN HARD SCIENCE – NOT THE MARKETING HYPE THAT WAS BEGINNING TO DOMINATE THE HIGH-END SPECIALTY GARDENING FIELD."

Bryce Patterson
founder of heavy 16

Some of my earliest memories of growing up in Orange, California are of working with my father on our family garden every day. I was always excited to discover new fruits and vegetables sprouting as a reward for our hard, but gratifying, work. By the time I was a teenager, my passion extended far beyond basic gardening and I was determined to pursue a career in agriculture, exploring new frontiers in plant science.

This passion led me to Cal Poly, San Luis Obispo, where I earned my degree in Agriculture/Horticulture Science. After years working for industry-leaders in agribusiness, I began formulating my own nutrient based on the demands of many local farmers that I had befriended over my lifetime.

I based HEAVY 16 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

It wasn’t long before word was spreading throughout California that HEAVY 16 nutrients were producing massive yields, of top-grade crops for serious growers. I quickly began receiving more requests for custom batches of HEAVY 16 and eventually decided to make my blend available to the growers across the country. The feedback has been phenomenal and I couldn’t be happier that my life’s work is helping so many people get the results they’ve been striving for. We are always available to answer any questions you may have and look forward to helping you achieve your agricultural goals.

  • Strong roots. Strong plants. Strong foundation. 🌲🌱

Just like the towering redwoods around us, great plants start with a solid foundation.

HEAVY VEG A & B is designed to support vigorous vegetative growth, delivering a balanced combination of essential nutrients to help plants develop strong roots, healthy foliage, and the structural integrity needed to thrive throughout their growing cycle.

With multiple forms of nitrogen, calcium, and micronutrients, our two-part VEG formula provides comprehensive nutrition without unnecessary complexity.

Because the bigger the goals, the stronger the foundation needs to be. 💪

  • Only you can grow the fire 🐻🔥

At HEAVY 16, we’ve never believed that top-tier craft is an accident: it’s an obsession! When your canopy pushes into mid-to-late bloom and the stakes are highest, off-the-shelf nutrient regimens tap out. That’s where HEAVY Fire takes over.

Formulated with a hyper-pure 1-10-16 profile, Fire isn’t designed to bulk up empty water weight or blast your root zone with cheap, harsh salts. It delivers clean, bio-available phosphorus and potassium engineered specifically to:

🔥 Stack Dense Calyxes: Drive tight, rock-solid flower development through peak floral swell.

🔥 Ignite Trich Production: Trigger secondary metabolite synthesis for unmatched resin density and frost.

🔥 Max Out Terpene Expression: Protect volatile aromatic profiles so your dry and cure actually smells like the garden on day 50!

  • 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 to make applying HEAVY Foliar as simple as possible? Keep reading! 📝

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.

  • A root promoter, and a lot more 🤘💦

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. But that isn’t all it can do! 🌿

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! 💧

  • If your flower looks incredible but tastes flat, PRIME will change the game for your garden 🪴

At HEAVY 16, Prime is the backbone of our system—an ultra-diverse liquid formulation designed to run from veg through finish, in any medium.

Because “cardboard terps” don’t come from lack of inputs… they come from a lack of biological depth.

Prime is built as a layered microbial feed, delivering everything your root zone needs to fully activate nutrient conversion and plant metabolism:

• Humic & fulvic acids for nutrient transport
• Amino acids + B vitamins for metabolic function
• Kelp + phytohormones for growth signaling
• Carbohydrates for microbial energy
• A full spectrum of trace minerals + multiple potassium sources

It’s FUELING the system beneath the plant.

The result is:

👃 Loud, cultivar-specific terp profiles
🍯 Increased resin, oil production, and density
🌱 Stronger roots, healthier growth
🔥 Clean burn, full flavor

PRIME, our centerpiece additive, sets the pH for you via complex organic acids. If your source water is roughly between a 5.5 and 8.0 on the pH scale, PRIME’s complexion will naturally titrate the pH, eliminating the need for hard acids in the garden 💪🌱

PRIME’s chemistry allows for flexibility throughout cultivation systems and alternative feeding programs from aeroponics to outdoor soil crops. Primes superiority to other products including proprietary derivatives and mixing procedures will eliminate your need for multiple other additives that would be considered redundant or incomplete according to our data 👌💵

Carbohydrate complexes, L-amino acid and B vitamin supplements, kelp and natural Phyto-hormone derivatives, and high-grade humic acids are all represented in PRIME’s composition 📗🔎

Along with these necessary standard constituents, we have added exotic trace element suite, six forms of potassium (including potassium silicate), yeast and plant extracts, ultra-fine low molecular weight fulvic acid, and proprietary organic acids to ensure your crop and its microbial life are optimally fortified and functioning at their peak metabolic/intelligence levels!
