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. #HEAVY16 #HEAVY16Nutrients #HEAVY16Roots #HEAVY16Veg

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! 🌿 #HEAVY16 #VegAB #PlantNutrition #GrowWithHEAVY #Hydrofarm

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. 🌿 #HEAVY16 #HEAVY16Nutrients #PPM #GrowWithHEAVY #Hydrofarm

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. #HEAVYFoliar #FoliarSpray #HEAVY16 #HEAVY16Nutrients #GrowWithHEAVY

Rocking the HEAVY tank in the garden 🪏😎 @mwreikiroom Even if she isn’t running HEAVY nutes on this veggie garden, she’s still repping! It’s all about the HEAVY mindset — heavy harvests, all the time 👊😎 Looking good! #HEAVY16 #HEAVY16Nutrients #HEAVY16Fam

Flat flower? Thin aroma? Missing that full-bodied flavor your genetics should be expressing? 🌱 It might not be your cultivar: it might be what’s happening beneath the plant. HEAVY PRIME is built to fuel the root zone from veg through finish, supporting the biological activity and nutrient conditions that help plants reach their full potential. Designed as a powerhouse microbial feed and sweetener, PRIME helps support microbial populations, improve overall plant nutrition, and create better soil/nutrient conditions for stronger crop performance. At the root of elite flower is an active, well-fed system, and PRIME brings the fuel. With a layered formulation featuring humic and fulvic acids, amino acids, B vitamins, kelp, phytohormones, carbohydrates, trace minerals, and multiple potassium sources, PRIME helps support nutrient transport, metabolic function, microbial energy, and the natural processes that drive better flavor, aroma, resin, and plant performance. That means louder terpene expression. Richer aroma. Improved sweetness and density. And flower that tastes as good as it looks. PRIME doesn’t contain live microbes itself — it feeds and supports the biological engine already working in your media, compost teas, inoculants, and root zone. It’s not just another additive. It’s the foundation underneath the finish. No more cardboard terps! 🚫📦 #HEAVY16 #HEAVY16Prime #GrowWithHEAVY #Prime #Hydrofarm

Use HEAVY Finish in soil AND foliar feedings! 💦 HEAVY FINISH is a high-quality formulation for mixing of mineral formulas.
