  • 🧪 Decades in the making, engineered for results! Heavy 16 isn’t just another nutrient line — it’s the product of a lifelong obsession with plant science, agricultural chemistry, and horticultural efficiency. Born in the gardens of Southern California and refined with careful field testing, our formulas were originally developed to meet the real-world demands of high-performance growers. Every product in the Heavy 16 lineup was built from the ground up with: ⚗️ Pharmaceutical-grade raw materials for superior uptake 🧬 Multi-path nutrient delivery systems for redundancy and resilience 🧫 Micro-batch production for full-spectrum quality control 🧠 Intelligent ratios of macro/micronutrients, chelators, and biological co-factors We spent years field-testing with top-tier California farmers — tuning and retuning until every bottle was dialed for maximum translocation, consistency, and performance. The result? A lean, efficient, highly concentrated nutrient system that gives you all the complexity of modern plant science — in a format that’s easy to run, easy to scale, and ridiculously effective in flower. We don’t do hype. We do real R&D — and the difference is in the yield 🤌 #HEAVY16 #HEAVY16Nutrients #GetBigGetHEAVY #BigGrowerPreferred #GrowWithHEAVY
  • Weekend plans 😎🤘 A little bit of work in the garden, and a whole lot of enjoying the fruits of our labor! 😗💨 Hope everyone has a good one! 👊 #HEAVY16 #HEAVY16Nutrients #GetBigGetHEAVY #GrowWithHEAVY
  • If your pup can sniff out quality, trust that your crops can too 💯🐕 This isn’t just some plant food, it’s a professional-grade nutrient system built to give growers strong roots, vibrant plants, and gnarly harvests from seed to bloom 📚👨‍🌾 HEAVY 16 is all about premium ingredients and a streamlined formula that gets the job done without the extra fluff 🤘 #GetBigGetHEAVY #GrowWithHEAVY #DogApproved #HEAVY16 #HEAVY16Nutrients
  • Hot off the production line 🔥 HEAVY16 pushes crops to their ultimate potential using a powerful combination of mineral and natural ingredients 🍃 in a system that is straightforward to apply and maintain. By hand-mixing each batch in small quantities, HEAVY16 can ensure quality and freshness that other brands just can’t match. ⁠ HEAVY16 products are brewed in micro-batches to ensure quality and freshness. Each ingredient is refined to ensure purity and consistency. HEAVY16 is committed to this artisanal approach to quality nutrient production. Based on our phenomenal results and customer feedback, we wouldn’t have it any other way. 🤙 #HEAVY16 #HEAVY16Nutrients #HEAVY16Bud #BudAB #GrowWithHEAVY

  • Paranormal root growth and rhizosphere health 💥 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! 💧 #GrowSmart #GrowYourOwn #GrowWithHEAVY #Indoor #Outdoor #HEAVY16Stacks #BigGrowerPreffered #HEAVY16 #Hydrofarm
  • Bringing the flavor with HEAVY PRIME 🍭🍓 Top-shelf flower 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 ALL unforgettable 🤘 #Heavy16 #FlavorMatters #TerpsMatter #HEAVY16Nutrients #HEAVYPrime #Prime #Flavor #GrowWithHEAVY #BigGrowerPreferred #HEAVY16Stacks

  • 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. #HEAVYFoliar #FoliarSpray #HEAVY16 #HEAVY16Nutrients #GrowWithHEAVY #HEAVY16Stacks #Foliar #BigGrowerPreferred
