  • Use HEAVY Finish in soil AND foliar feedings! 💦 HEAVY FINISH is a high-quality formulation for mixing of mineral formulas. FINISH can be applied to trees and vines, vegetable and field crops, turf and greenhouses and various ornamental species! Use HEAVY FINISH to cleanse impurities, express natural plant flavors, and unlock rich, full-bodied aromas. HEAVY FINISH promotes the natural qualities of a plant’s genetic composition by cleaning unwanted build-up of common impurities. Use HEAVY FINISH in low dosage as directed through a plant’s life cycle, and a larger dose for the final flushing before harvest. #HEAVY16 #HEAVY16Nutrients #HEAVYFinish #Foliar #FoliarSpray #Flush #HEAVYOnScienceLightOnPrice #BigGrowerPreferred

  • A root promoter, root protector, and drip cleaner/anti-precipitate all in one! 🌿 NOW EVEN MORE AFFORDABLE 🚨 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 🌿 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! 💧 Photo Credit: @killsm0ke 📸 #GrowSmart #GrowYourOwn #GrowWithHEAVY #Indoor #Outdoor #Greenhouse #Soil #Soiless #Hydroponics #HEAVY16Stacks #BigGrowerPreffered #Horticulture #Gardening #HEAVY16 #HEAVY16Nutrients #HEAVYOnScienceLightOnPrice #GetBigGetHEAVY
  • 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!   #HEAVY16 #HEAVY16Nutrients #TheMoreYouKnow #GrowYourOwn #Big Yields #CascadingDelivery #BigGrowerPreferred #GrowWithHEAVY #AskHEAVY #TeachMeHowToHEAVY #GrowWithHEAVY
