Make the switch, never look back — just ask our growers! 👊
Here’s the full testimonial from a satisfied @baysidegardensupply customer:
“Before being introduced to Heavy 16 many years ago, I was incorporating 20+ different products from various nutrient lines into my feed schedule. Grow/Bloom/Micro bases from here or there, Cal-Mag from another source, Silica, Humic/Fulvic acids, carbohydrates, high PK bloom enhancers, potassium sulfate, etc. etc. etc.
There was never a “do it all” nutrient line...until Heavy 16. Not to mention the complete lack of salt buildup! What a miracle! I do still like to add a biological inoculant product and an enzyme to keep my soil healthy & the plant’s roots clean & active, but going from 20+ bottles to 8 really made life easier.
And to this day Heavy remains the most complete & highest performing line on the market. I’ve never looked back. The cal-mag is built into the bases (Veg A&B, Bud A&B), the Prime has 3 silica sources as well as humic & fulvic and all your carbohydrates, potassium sulfate and terpene enhancing extracts in the Finish, PK boost & disease preventing phosphite in the Fire, just to scratch the surface.”
Want to give a big shoutout to @baysidegarden for their continued support! 🤘

Grow your FIRE with HEAVY FIRE🔥
HEAVY FIRE is a hand-crafted P/K booster built with real nutritional chemistry behind it — brewed and aged (not just blended) to create a truly unique, balanced bloom supplement. It slides seamlessly into any nutrient program thanks to its ultra-fine minerals and natural homogenization.
Kick it on in the last 1–2 weeks of veg and ramp it through the entire bloom cycle. You’ll get early support before flower set, stronger late-phase (“Cascading”) phosphorus delivery, and all the ingredients needed for a bigger, more resilient root mass with fuller, more branched foliage 💥
Powered by three forms of phosphorus (including highly effective phosphite), three forms of potassium, and ammonium nitrogen to improve P uptake. Finished with a premium cold-processed kelp mix to naturally support blooming — it’s one bottle that simplifies your regimen and brings out the full potential locked in your plant’s genetics. 🔥🌱

Balanced flowering nutrition! 🤟🔥
When it comes to the flowering stage, your plants deserve nothing less than premium nutrition. HEAVY BUD A&B is built to deliver just that: a cascading flow of high-quality Calcium, micronutrients, and a proprietary Phosphorous + Potassium blend designed to push plants toward robust, top-shelf yields 🚀
Formulated with low salt-indexed ingredients, exotic trace elements, and four distinct forms of Calcium, this powerful base nutrient fuels every phase of the bloom cycle with precision and consistency. The result? Dense, resin-packed flowers and vibrant health from start to finish 🤌
Ready to take your flowering game to the next level? Use BUD A&B throughout your entire bloom cycle, following our custom nutrient schedule here at heavy16.com/nutrient-calculator 👊

Don’t forget HEAVY16 can be used on seedlings and cuts! 🌱
Found in the first column of our feed cards, or at https://www.heavy16.com/nutrient-
calculator/. As shown, values are per gallon.
You can pretreat with this solution for increased success rates during propagation as well as feed your freshly rooted seedlings or cuts! 🌿
#ROOTS will promote root development while stopping pythium and other possible infections in its tracks! Less damping off... more growing up!
Once rooting has started the low levels of our VEG base will help maintain growth, eliminating the nutritional stress in that transition for the little ones.

Built different by design 💪
Our lineup isn’t about bloated feed charts or unnecessary additives. It’s a streamlined, science-driven nutrient system made with premium raw ingredients and small-batch blending for consistency you can trust. Every formula is designed for maximum bioavailability, so plants get exactly what they need, when they need it.
✔️ Balanced Veg & Bud A&B for strong structure, healthy growth, and heavy yields
✔️ Prime, Fire & Foliar deliver targeted support for roots, terpenes, and overall plant vitality
✔️ Works seamlessly in soil, coco, and hydro
✔️ Clean inputs that support both plants and beneficial microbes
Growers running HEAVY 16 consistently see stronger roots, thicker stalks, healthier plants, and better finishes: without overcomplicating the grow.

Strong veg sets the stage for everything that follows. 🌱💪
HEAVY 16 Veg A & B is built to give plants a powerful, balanced foundation during the vegetative stage — supporting overall plant nutrition, optimizing nutrient conditions, and helping crops build the structure they need before the demands of bloom.
This two-part base keeps the program simple without cutting corners. Instead of overcomplicating your feed room with a shelf full of bottles just to get through veg, HEAVY 16 Veg A & B (and Bud A and B) deliver a professional-grade foundation in a straightforward A/B format and is complimented by only FIVE other additives total.
The goal: healthy, vigorous plants with the strength to support bigger growth later on. From root development to leaf expansion to overall plant structure, Veg A & B helps growers dial in the early stages with confidence.
That’s what sets HEAVY 16 apart: complex formulation, simple application, premium results. The line is designed for growers who want high-performance nutrition without unnecessary guesswork — and Veg A & B is where that system starts.
Build the plant first and the harvest follows! 🌿

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
Why isn’t HEAVY 16 based off of a PPM Scale? 📝
PPM’s have long been used to gauge nutrient strength in irrigation water. While this method can still be employed, HEAVY16 utilizes a cascading delivery system with multiple nutrients that have no charge out of the bottle, and therefore won’t register on an EC or PPM meter. These neutral organic minerals have a potent nutritional value that becomes available to your plants over time. Hence, we prefer to use specific dosing increments (mL) per gallon to measure fertility versus PPM’S 🧪
You can still use the PPM/EC scale as a judgment tool when auditing your water chemistry over time. Additionally, we do recommend using such measurements when assessing the hardness of your water and efficacy of your filtration system. 🌿

We make using HEAVY Foliar as simple as possible! Read this caption and take notes… 📝
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.
